Description

[0001] The invention relates to a method for producing an embossed insulating packaging, a plant for producing an embossed insulating packaging and an embossed insulating packaging.

[0002] State-of-the-art insulated packaging made of expanded polystyrene (EPS) is known for enabling mobile product cooling. The products to be cooled are placed in a container, usually a square EPS box, along with a cooling medium, such as ice packs or dry ice, and sealed with a removable EPS lid. Depending on the performance of the cooling medium, the products can be cooled for several hours or even up to several days, for example, two days. The EPS box with the lid closed can be placed in a shipping carton and shipped.

[0003] In many cases, when shipping refrigerated products such as food or medicine, the insulated packaging is disposed of after use. For environmental reasons, a recycling process for the insulated packaging is preferred. There are no established recycling processes for EPS materials, especially for private households. Furthermore, EPS is a mineral material, so its recycling requires an energy-intensive process. Consequently, the use of EPS as insulated packaging is associated with high manufacturing and recycling costs.

[0004] A more environmentally friendly solution for insulating packaging is known from DE 10 2022 119 517 A1, which discloses insulating packaging made from recycled paper that can be used to insulate refrigerated containers. The insulating packaging is long enough to be inserted into a packaging carton in a curved shape such that it covers at least one edge and one side surface of the packaging carton. Covering the edges of a packaging carton used as a refrigerated container is particularly important for the insulating effect, since thermal bridges often form at edges, reducing the insulating effect.

[0005] An insulating packaging is known from AT 525 089 A4, in which cellulose fibers are incorporated into a quilted tubular bag for insulation. Quilted areas are free of cellulose fibers, so that opposing surfaces of the insulating packaging are connected in a force-transmitting manner. The insulating packaging can be folded in the area of ​​the quilting, causing padded areas of the quilted tubular bag chambers to abut one another, forming an insulated interior.

[0006] Furthermore, a food packaging is known from DE 691 29 766 T2, in which a nonwoven film is bonded to a cardboard box by means of needlepoint embossing. The nonwoven film comprises a hydrophobic fiber layer and an absorbent fiber layer comprising cellulose fibers, which are processed into the nonwoven film using meltable polyethylene binding fibers.

[0007] A system for producing a packaging container using an embossing process is known from DE 23 62 256 A1.

[0008] Therefore, there is a constant effort in the production of insulated packaging to avoid thermal bridges, especially around the edges of a refrigerated container. This goes hand in hand with the effort to find technical solutions to provide insulated packaging that reproducibly avoid any thermal bridges.

[0009] Based on the prior art, the invention is based on the object of enabling the reproducible production and use of an insulating packaging while avoiding thermal bridges.

[0010] This object is achieved according to the invention by the subject matter of the independent claims. Further developments can be found in the dependent claims.

[0011] A method for producing an embossed insulating packaging is provided, comprising the following steps: providing an insulating packaging comprising cellulose fibers forming a fiber carpet and surrounded by wrapping material; and embossing the insulating packaging.Embossing the insulating packaging comprises the steps of positioning the insulating packaging relative to an embossing tool using a transport device; moving the embossing tool and / or the transport device into an embossing position; applying an embossing pressure to the insulating packaging using the embossing tool and allowing the embossing tool to remain in the embossing position while exerting the embossing pressure for a predetermined embossing time, so that the fiber carpet is compressed in the engagement region of the embossing tool; moving the embossing tool and / or the transport device into an open position; and removing the embossed insulating packaging from the embossing tool using the transport device. The above method steps are preferably carried out in the order listed.

[0012] The process introduces a defined embossing into the insulating packaging, which can be characterized by a clear and defined embossing line. The process can therefore be used to produce embossed insulating packaging that has a defined embossing with an embossing line. The embossing line can be free of fraying transverse to the embossing line. The embossing or embossing line can provide a defined folding or crease point for the embossed insulating packaging. A folding or crease process is understood here to mean the movement of connected surfaces towards one another so that the surfaces enclose an angle of less than 180 degrees. The apex of the angle can be formed by the embossing or the embossing line or the crease / fold line. By embossing the insulating packaging, it can be ensured that the insulating packaging retains its insulating effect in the area of ​​the crease / fold and thermal bridges are avoided.In the following, the synonymous terms “folding” and “creasing” are summarized under the term “creasing” and its declined uses.

[0013] The step of removing the embossed insulating packaging from the embossing tool can be followed by a step of folding the embossed insulating packaging, with the embossing defining the folding point. The embossing can lead to a folding point that can be reproducibly introduced into the insulating packaging. The folded and embossed insulating packaging can, for example, be introduced into outer packaging, e.g. an outer carton. The defined folding of the embossed insulating packaging made possible by the embossing simplifies alignment of the insulating packaging relative to the outer packaging. The embossing or folding point can be arranged adjacent to an inner edge of the outer packaging, while side surfaces of the outer packaging and the embossed insulating packaging adjoining the embossing are opposite one another.Defined bends achieved through embossing can therefore reduce the number of steps required to align the embossed insulating packaging with the outer packaging. The defined bends achieved through embossing can also prevent the embossed insulating packaging from slipping within the outer packaging, which in turn prevents the formation of undesirable thermal bridges.

[0014] The introduction of at least one embossing into the insulating packaging and the resulting defined crease can be achieved using an automated process. Likewise, the folding of the embossed insulating packaging can be automated, with the embossing line forming the crease line. This simplifies the reproducible production of embossed insulating packaging that consistently avoids thermal bridges.

[0015] The insulating packaging, in its embossed or unembossed form, preferably comprises a wrapping material and a filling in the form of a fiber carpet. The fiber carpet is preferably continuous. The wrapping material preferably forms a sealed bag that completely surrounds the fiber carpet.

[0016] The wrapping material comprises, for example, a plastic-coated paper layer, which forms a sealed bag by forming at least one sealing section. The wrapping material is preferably free of adhesives, except for a possible sealing layer for sealing the wrapping material. Opposing wrapping material surfaces of the wrapping material are completely separated from one another by the fiber carpet, specifically in the region of the unembossed and the embossed fiber carpet. This means that opposing wrapping material surfaces of the wrapping material are spaced apart from one another and only touch in the region of the sealing surfaces to form the wrapping material.

[0017] The fiber carpet can have a continuous length of more than 60 cm, preferably more than 70 cm, more preferably more than 80 cm, and a continuous width of more than 20 cm, preferably more than 30 cm, more preferably 40 cm or more. According to the invention, the cellulose fibers of the fiber carpet are loosely bonded to one another, e.g., without adhesive. The fiber carpet can have a continuous length and width, e.g., it contains no defects that could cause thermal bridges.

[0018] The use of cellulose fibers is advantageous from an ecological perspective, as they can be obtained from recyclable materials such as waste paper. Consequently, CO2 consumption is significantly reduced compared to the use of EPS. Furthermore, the use of cellulose fibers enables energy-efficient production, with energy consumption being reduced by 5 to 10% compared to the production of conventional EPS insulation packaging, for example. Recycling materials made from cellulose fibers is also very easy. It can be disposed of like waste paper, for which established recycling processes exist for both private households and industrial applications.

[0019] The cellulose fibers provide the desired insulating effect. To achieve this, they preferably have a low thermal conductivity, for example, 36 mW / m*K (lambda). This thermal conductivity is superior in terms of its insulating effect compared to conventional blown-in insulation materials, which have a thermal conductivity of 40 mW / m*K (lambda), and is almost as high as the thermal conductivity of EPS.

[0020] Particularly low thermal conductivity of cellulose fibers can be achieved when the fibers are short and thin. Shorter and thinner fibers can be more flexible and thus form more homogeneous cellulose materials with a uniform pore size distribution. Longer fibers can have more irregular air inclusions, which can lead to an inhomogeneous density distribution and fluctuating mass distribution in the longitudinal and transverse directions. This can create thermal bridges, which lead to an increase in thermal conductivity.

[0021] Furthermore, it has been shown that low fiber fibrillation – fibrils are fine hairs on the fiber surface that point into the open space and can come into contact with other fibers – can be beneficial for the insulating properties of cellulose fibers. Fibrils can act as spacers between the fibers, thus supporting the formation of a fine-pored structure with a high air volume inclusion.

[0022] In some embodiments, the cellulose fibers are provided by shredding comminuted cellulose materials comprising cellulose fibers. Preferably, shredded cellulose materials are obtained by shredding cellulose materials. The cellulose fibers are processed into a fiber carpet, for example, according to a process described in DE 10 2022 119 517 A1.

[0023] Cellulose material can include paper, cardboard, waste paper, and newspapers. Cellulose material also includes all materials that consist primarily of cellulose fibers. For example, recycled waste paper B12 can be used. Waste paper or mixed paper B12 consists of newspapers, cardboard, and writing paper, and preferably contains a maximum of 40% newspapers or magazines.

[0024] The embossed insulating packaging produced by the above process preferably has a thickness of 20 mm to 25 mm with a standard basis weight of between 800 g / m 2 and 1350 g / m 2 , preferably between 1200 g / m 2 and 1300 g / m 2 , more preferably 1250 g / m 2. In another embodiment, the embossed insulating packaging produced by the above method may preferably have a thickness of 25 mm to 35 mm with a standard basis weight of between 1700 g / m 2 and 2000 g / m 2 , preferably between 1750 g / m 2 and 1850 g / m 2 , more preferably 1800 g / m 2 Generally speaking, the insulating packaging can have a standard basis weight of at least 800 g / m 2 , at least 1000 g / m 2 or at least 1200 g / m 2 and / or a standard basis weight of maximum 2000 g / m 2 , maximum 1800 g / m 2 or a maximum of 1600 g / m 2 have.

[0025] The wrapping material preferably completely surrounds the fiber carpet. In the embossed insulating packaging, the wrapping material is preferably completely sealed. When the cellulose fibers are introduced and / or the fiber carpet is formed, the wrapping material preferably has a bag shape with three closed sides and a filling opening. It can be sealed, for example, via sealed seams at both longitudinal ends and a sealed seam along the length of the wrapping material. Preferably, no air and / or moisture can enter or escape from the completely sealed wrapping material. The bag made of wrapping material is therefore preferably hermetically sealed.

[0026] The wrapping material preferably remains undamaged by the embossing process. It may undergo a change in shape in the area of ​​the embossing, although this may be temporary. It is conceivable that the change in shape of the wrapping material will diminish over a longer period of time, even a year or more. The change in shape may be visible to the naked eye. The wrapping material may have an indentation caused by the embossing, for example a V-shaped indentation. The material structure of the wrapping material preferably remains unchanged by the embossing. In other words, the pressure or force applied to the wrapping material by the embossing process leads, for example, to the change in shape of the wrapping material in the area of ​​the embossing.

[0027] The fiber carpet preferably remains undamaged by the embossing process. It experiences compression in the area of ​​the embossing, although this may be temporary. It is conceivable that the compression of the fiber carpet decreases over a longer period of time, even a year or more, and with corresponding agitation. The change in shape may be visible to the naked eye (once the wrapping material is removed). The fiber carpet may exhibit an indentation caused by the embossing, for example a V-shaped indentation. The fiber carpet retains its continuous length and width during the process; only its fiber carpet thickness is changed in the area of ​​the embossing. In other words, the pressure or force applied to the fiber carpet during the embossing process leads, for example, to the compression and change in shape of the fiber carpet in the area of ​​the embossing.

[0028] The embossed insulating packaging has an insulating effect in both the embossed and unembossed areas. The fiber carpet can be bendable along the embossing / embossing line while retaining its insulating properties. Thermal conduction can be slightly greater in the embossed area than in the adjacent unembossed areas of the fiber carpet. However, thermal conduction in the embossed area can be such that no thermal bridges exist in the embossed areas. Consequently, undesirable thermal bridges are avoided. The fiber carpet is not damaged, for example, by the embossing process, i.e., by its compression, and subsequent bending. The fiber carpet can be compressed but retain its continuous length and continuous width, without any defects.

[0029] The transport device can move the insulating packaging in a transport direction. The insulating packaging is held by the transport device, for example, by gravity and frictional forces acting between the insulating packaging / embossed insulating packaging and the transport device. The transport direction preferably runs in the horizontal direction of the transport device.

[0030] The method step of positioning the insulating packaging can be performed by moving the insulating packaging held by the transport device to the embossing tool by means of the transport device. A position sensor can detect when the insulating packaging is in a working position. For example, two position sensors can be provided, wherein when a first position sensor detects the insulating packaging, the speed of the transport device is reduced, and when a second position sensor detects the insulating packaging, the transport device is stopped.

[0031] The step of moving the embossing tool and / or the transport device into the embossing position can be carried out by means of a movement device that is driven, for example, by compressed air. Furthermore, the movement device can be configured to apply the embossing pressure that is applied to the insulating packaging by the embossing tool and / or can be configured to move the embossing tool into the open position. The embossing pressure can be controlled during the embossing process and applied by the embossing tool for a predetermined time. The embossing pressure applied to the insulating device can be between 2 bar and 10 bar, preferably between 4 bar and 8 bar, more preferably about 6 bar. The embossing time can be between 0.5 seconds and 2 seconds, preferably about 1 second. The embossing pressure is maintained during the embossing time.

[0032] According to an advantageous embodiment, the steps of embossing the insulating packaging can take place while the insulating packaging is held by a transport section of the transport device. The steps of embossing the insulating packaging comprise, for example, the following steps: positioning the insulating packaging relative to an embossing tool by means of a transport device; moving the embossing tool and / or the transport device into an embossing position; applying an embossing pressure to the insulating packaging by means of the embossing tool and allowing the embossing tool to remain in the embossing position while exerting the embossing pressure for a predetermined embossing time, such that the fiber carpet is compressed in the engagement region of the embossing tool; moving the embossing tool and / or the transport device into an open position; and removing the embossed insulating packaging from the embossing tool by means of the transport device.In this way, the embossing process is carried out efficiently. There is no need to move the insulating packaging between its unembossed and embossed state, thus achieving a short process time. Additional steps for moving the insulating packaging from, for example, one conveyor belt to another conveyor belt are eliminated. The transport device can be in an embossing position when it engages in the at least one recess of the embossing tool. Likewise, the transport device can be in an open position when it is disengaged from the at least one recess of the embossing tool.

[0033] Before the embossing pressure is applied and during the movement of the embossing tool and / or the transport device into the embossing position, the embossing tool can come into engagement with the insulating packaging. In one embodiment, the insulating packaging can be lifted by the embossing tool in the embossing position, at least in an area intended for embossing. The area intended for embossing is the area in which the embossing is introduced after the embossing process. During lifting, the insulating packaging can detach from the transport device, at least in the area intended for embossing. The lifting of the insulating packaging by the embossing tool can be only slight; for example, the insulating packaging can be lifted in the area intended for embossing by between 10 mm and 100 mm, preferably between 15 mm and 80 mm, more preferably between 15 mm and 50 mm.In an exemplary embodiment, the insulating packaging can be raised between 20 mm and 30 mm.

[0034] Embossing is preferably carried out at room temperature. Cooling or heat input during embossing can be omitted.

[0035] In the embossing position, a section of the transport device can be located in the at least one recess of the embossing tool. During embossing, the transport device can engage in the at least one recess of the embossing tool. The transport device can engage in at least one recess of the embossing tool when the embossing tool is moved into the embossing position and / or when the transport device is moved relative to the embossing tool into the embossing position. When the embossing tool is moved into the open position and / or when the transport device is moved relative to the embossing tool into the open position, the transport device can be disengaged from the embossing tool. A movement of the transport device comprises a displacement movement of the transport device according to a movement path of the embossing tool and / or a movement transverse to this and / or a movement in the transport direction.

[0036] In one embodiment, the embossing tool can comprise a first embossing unit and a second embossing unit that cooperates with the first embossing unit. The first embossing unit can comprise the at least one recess. For example, a portion of the transport device engages in the at least one recess of the first embossing unit. This technical solution can serve to ensure that the insulating packaging is held by the transport device in its embossed and unembossed state, as well as during the embossing process steps, thereby achieving a short process time.

[0037] The step of moving the embossing tool and / or the transport device into an embossing position can be carried out by means of the following sub-steps: controlling the first embossing unit to move it from the open position into the embossing position; moving the first embossing unit relative to and in the direction of the insulating packaging and / or moving the transport device relative to the first embossing unit; controlling the second embossing unit to move it from the open position into the embossing position, wherein the controlling of the second embossing unit takes place in a chronological sequence after the controlling of the first embossing unit; and moving the second embossing unit relative to and in the direction of the insulating packaging.

[0038] While the stamping tool remains in the stamping position and exerts stamping pressure for a predetermined stamping time, the first stamping unit and the second stamping unit are spaced apart by a defined stamping distance. The distance between the first and second stamping units can be monitored using an end-position sensor. This defined stamping distance enables reproducible pressure application during stamping.

[0039] According to a further aspect of the invention, the above object is achieved by a system for embossing an insulating package, i.e., for producing an embossed insulating package. The system is preferably suitable for producing an embossed insulating package that can have the features defined below. Furthermore, the system can, for example, be used to produce an embossed insulating package produced according to the above method.

[0040] The system for embossing insulating packaging comprises a device frame and at least one embossing station attached to the device frame. The embossing station comprises an embossing tool formed with at least one recess, and a movement device for moving the embossing tool between an open position and an embossing position, wherein the embossing tool is configured to emboss the insulating packaging in the embossing position. The system further comprises a transport device attached to the device frame for transporting the insulating packaging relative to the embossing station, wherein a transport section of the transport device is configured to feed the insulating packaging to the embossing station, to hold it during an embossing process, and to guide it out of the embossing station. In the embossing position, at least a portion of the transport section is located in the region of the at least one recess of the embossing tool.

[0041] With the system defined above, the advantages previously described for the process are achieved in an analogous manner. The system can be used to reproducibly produce embossed insulating packaging with a clearly defined embossing or embossing line, which enables folding along the embossing and prevents the formation of a thermal bridge in the folding area. The embossing line can therefore represent the folding line. Furthermore, the system enables effective and short processing times by configuring the transport device to hold the insulating packaging during the embossing process, as well as when feeding the insulating packaging to the embossing tool and when removing the embossed insulating packaging from it.

[0042] The properties of the wrapping material, the fiber carpet and the embossed insulating packaging mentioned at the beginning with regard to the first aspect of the invention apply equally to the second aspect of the invention.

[0043] The insulating packaging or the embossed insulating packaging is moved in a transport direction relative to the embossing station. The transport direction can be along a longitudinal extension of the transport device. The transport direction can always be in the same direction, i.e., the transport direction when positioning the insulating packaging relative to the embossing tool and when removing the embossed insulating packaging from the embossing tool can be the same.

[0044] The embossing station can be movably mounted on the device frame to enable displacement of the embossing station in the transport direction as well as against this. In this way, the position of the embossing relative to the device frame can be adjusted. The system can preferably have two embossing stations, which can be identically designed. For example, one of the two embossing stations can be fixedly attached to the device frame, i.e. cannot be moved, and the other can be moved. Both embossing stations can also be movably attached to the device frame to increase the flexibility of the system. The displaceability of at least one of the embossing stations enables the realization of different embossing patterns.

[0045] For a compact system design, the transport device can be fixedly attached to the device frame. Alternatively, the transport device can be mounted on the device frame in a height-adjustable manner. For example, the transport device can be rotatably attached to the device frame by means of deflection elements. The deflection elements can be driven in rotation by a motor. The transport device can thus be movable around the deflection elements and have a circumferential shape. The deflection elements can, for example, be deflection rollers. A transport section of the transport device, on which the insulating packaging is held, moves in the transport direction.

[0046] For example, the transport device comprises at least two circulating belts designed to hold the insulating packaging. A portion of a belt of the transport device can engage in the at least one recess of the embossing tool. The deflection elements (e.g., deflection pulleys) can hold the at least two circulating belts. For example, the transport device comprises three circulating belts, preferably four circulating belts, designed to hold the insulating packaging. A belt can be understood as an element whose longitudinal extent is significantly greater than its width. A belt width is, for example, less than or equal to 2 cm.

[0047] The belts can be guided by guide elements, e.g., guide rods. The belts can be attached to the device frame in such a way that their spacing from one another can be adjusted.

[0048] A transport section of the transport device corresponds to the outer dimensions of the insulating packaging in at least one dimension, for example, a longitudinal extension. The transport section of the transport device preferably runs horizontally. This allows the insulating packaging to be securely held in its embossed and unembossed state.

[0049] The embossing tool can comprise a first embossing unit and a second embossing unit that interacts with the first embossing unit. The first and second embossing units can be movable relative to one another to assume an embossing position, in which the first and second embossing units are moved toward one another, and an open position, in which the first and second embossing units are spaced apart from one another sufficiently for the insulating packaging to be movable between them. During the embossing process, the first and second embossing units are preferably in the embossing position. In the embossing position, for example, the section of the transport device is located in the region of the at least one recess of the first embossing unit.

[0050] Alternatively or additionally, the movement device may be configured to move at least one of the first embossing unit and the second embossing unit relative to the other between the embossing position and the open position, wherein the first embossing unit and the second embossing unit are configured to emboss the insulating packaging in the embossing position.

[0051] According to one embodiment, an adjustment device, e.g., a height adjustment device, of the transport device can move the insulating packaging into the embossing position while the first embossing unit is stationary. Embossing can be performed by moving the second embossing unit into the embossing position relative to the first embossing unit.

[0052] A space-saving solution can provide for the first embossing unit to be arranged vertically below the second embossing unit. The first embossing unit can be moved relative to the transport device by means of the movement device. The second embossing unit can be moved relative to the transport device by means of the movement device.

[0053] The first embossing unit can comprise the at least one recess. In more detail, the first embossing unit can have an embossing surface that is interrupted by the at least one recess. The first embossing unit can be interrupted in its longitudinal extension by the at least one recess. The first embossing unit can therefore comprise at least two separate embossing elements. In one embodiment, the embossing unit comprises, for example, four recesses and five embossing elements. An embossing surface of the second embossing unit can be continuous.

[0054] The longitudinal extent of the first and / or second embossing unit can be greater than 65 cm, preferably greater than 75 cm, and more preferably greater than 85 cm. In this way, the system can be used to emboss insulating packaging with a transverse extent of up to 65 cm, preferably up to 75 cm, and more preferably up to 85 cm or greater.

[0055] According to a preferred embodiment, the first embossing unit and / or the second embossing unit are movable relative to the device frame at an angle between 20° and 160°, preferably at an angle between 80° and 100°, to the transport section. Consequently, the transport section of the transport device and the embossing units of the embossing tool can be arranged substantially perpendicular to one another. The extent of the embossing units can be determined by their movement path when at least one of the first and second embossing units is moved into the embossing position and / or the open position.

[0056] An embossing suitable for bending can be achieved if the first embossing unit has one or more concave embossing elements and the second embossing unit has one or more convex embossing elements. The concave and convex shapes of the embossing elements are, for example, complementary.

[0057] Pressurization of the insulating packaging during embossing can be achieved using compressed air. In one embodiment, the movement device can be actuated by compressed air. The movement device can preferably comprise a first movement device for moving the first embossing unit and a second movement device for moving the second embossing unit.

[0058] The movement device can be configured to exert an embossing pressure of between 2 bar and 10 bar, preferably between 4 bar and 8 bar, more preferably approximately 6 bar. The movement device can be configured to maintain the embossing pressure for an embossing time of between 0.5 seconds and 2 seconds, preferably 1 second.

[0059] For the reproducible production of an embossed insulating packaging, the system can further comprise at least one position sensor configured to detect the position of the insulating packaging. For example, the device can comprise two position sensors, wherein when a first position sensor detects the insulating packaging, the speed of the transport device is reduced, and when a second position sensor detects the insulating packaging, the transport device is stopped.

[0060] The system may include a control unit for controlling the movement device. For example, the control unit may control the movement of the first embossing unit and / or the second embossing unit such that they are moved into the embossing position and / or the open position. The device may include a control unit for controlling the transport device. The control unit may receive signals from the at least one position sensor and stop or start a movement of the transport device based on the signals from the at least one position sensor.

[0061] The device may comprise at least one pressure sensor configured to detect the embossing pressure applied by the first and second embossing units. In this way, the embossing process can be monitored.

[0062] The device may comprise at least one end-position sensor configured to detect the end position of the first and / or second embossing unit during the embossing process. This contributes to a reproducible embossing process.

[0063] According to a further aspect of the invention, the above object is achieved by an embossed insulating packaging. The insulating packaging is preferably produced using a method according to the first aspect of the invention. The insulating packaging is preferably produced using a system according to the second aspect of the invention. The embossed insulating packaging comprises a wrapping material comprising a (e.g. plastic-coated) paper layer which forms a bag by forming at least one composite section (e.g. a sealing section), and a filling which comprises a fiber carpet made of cellulose fibers. The fiber carpet has a continuous length of more than 60 cm, preferably more than 70 cm, more preferably more than 80 cm, and has a continuous width of more than 20 cm, preferably more than 30 cm, more preferably 40 cm or more.The fiber carpet has a first fiber carpet thickness in an unembossed area of ​​the fiber carpet and a second fiber carpet thickness in an embossed area of ​​the fiber carpet. The second fiber carpet thickness is at least 20%, preferably at least 30%, and more preferably at least 50%, less than the first fiber carpet thickness.

[0064] The properties of the wrapping material, the fiber carpet and the embossed insulating packaging mentioned at the beginning with regard to the first aspect of the invention apply equally to the third aspect of the invention.

[0065] An embossing on the embossed insulating packaging can define a fold or crease line. The embossing can define an embossed line. The embossed line can represent the crease or fold line.

[0066] For example, the fiber carpet thickness is understood to mean the extent of the fiber carpet in a direction that is perpendicular to the length and transverse extent of the fiber carpet.

[0067] The first fiber carpet thickness is preferably between 15 mm and 35 mm, preferably between 20 mm and 30 mm, more preferably between 20 mm and 25 mm. The second fiber carpet thickness is preferably between 3 mm and 15 mm, preferably between 5 mm and 12 mm, more preferably between 7 mm and 10 mm. In this way, thermal bridges can be effectively avoided, even if the embossed insulating packaging is bent in the embossed area.

[0068] A longitudinal extension of the embossing, ie a longitudinal extension of the second fiber carpet thickness, is for example between 20 mm and 60 mm, preferably between 25 mm and 55 mm, more preferably between 30 mm and 50 mm.

[0069] In one possible embodiment, at least one of the width and the length of the continuous fiber carpet is at least 60 cm long. Furthermore, the width of the fiber carpet in one embodiment can be between 55 and 65 cm, preferably 60 cm. Furthermore, the length of the fiber carpet can be between 30 cm and 200 cm or more than 200 cm. Larger dimensions of the fiber carpet make it possible to use the embossed insulating packaging with few or no thermal bridges. If the fiber carpet or the embossed insulating packaging is inserted into an outer packaging, for example, its length allows it to be guided around edges or corners and cover them without creating a thermal bridge.

[0070] The wrapping material can, for example, form a completely sealed bag by means of sealing sections. One of the sealing sections can connect two opposite ends of the wrapping material to each other, creating a wrapping material tube with a circumferentially closed surface. Another sealing section can close the wrapping material tube to form an open bag. Another sealing section can close the bag, which is open at one end, to form a completely sealed bag. Furthermore, other sealing sections are conceivable, as long as a completely sealed bag is formed in which the fiber carpet can be accommodated. The bag is preferably hermetically sealed.

[0071] The fiber carpet is continuous. This means that the fiber carpet is preferably uninterrupted along its length and width. Furthermore, the wrapping material is preferably continuous. This means that the wrapping material preferably has no divisions into compartments and / or quilted seams. In other words, the bag formed from the wrapping material comprises exactly one chamber for accommodating the filling, i.e., the fiber carpet.

[0072] Advantageously, the second fiber carpet thickness is achieved by compressing the fiber carpet. In other words, a compression process can be used to achieve the lower second fiber carpet thickness. One possible process for compressing the fiber carpet is described in the first aspect of the invention. The compression can be achieved by applying force or pressure, e.g., in an embossing process. Other pressure-applying processes are known to those skilled in the art, such as applying pressure using rollers. The compression of the fiber carpet is achieved by applying force to the fiber carpet and / or the wrapping material surrounding the fiber carpet.

[0073] The embossing of the embossed insulation packaging can be visually visible to the naked eye, which simplifies the subsequent folding of the embossed insulation packaging. For example, the wrapping material adjacent to the embossing of the fiber carpet can be embossed in such a way that the wrapping material exhibits a deformation at the embossing point. The deformation can be a V-shaped notch. A semicircular or square notch in the wrapping material is also possible. The shape of the notch is essentially determined by the shape of the embossing tool used.

[0074] For reproducible folding of the embossed insulating packaging, it has proven advantageous if the embossing runs along a straight line.

[0075] Generally, the embossing line follows the shape of the embossing tool and its alignment relative to the insulation packaging during the embossing process. Straight embossing lines are preferred. The embossing line can be exactly straight, i.e., free of deviations such as lateral grooves deviating from the straight line. The embossing line can represent a defined and reproducible crease in the embossed insulation packaging. The embossing line can be free of interruptions.

[0076] The introduction of a defined embossing / embossing line increases the reproducible folding of the embossed insulation packaging. In addition, the embossing prevents the fiber carpet from breaking at a folding point, i.e., the continuous length and width of the fiber carpet is interrupted at certain points. This danger arises if the continuous fiber carpet is folded without the prior introduction of an embossing line along which the fiber carpet is compressed. In other words, without a defined embossing line as a folding point, the continuous fiber carpet can tear and an undesirable thermal bridge can arise. Furthermore, by folding the fiber carpet - without prior embossing - the desired compression of the fiber carpet in the folding area cannot be achieved, which means that the insulation in the folding area cannot be produced reproducibly.If the insulated packaging is folded without prior embossing, the fold is not reproducible and does not show a straight, clearly defined crease line, but rather a rounded shape with a broken crease line. It goes without saying that this is difficult to reproduce and consequently makes it difficult to incorporate into an outer packaging.

[0077] Two embossing lines can run parallel to each other so that the embossed insulating packaging can be reproducibly folded at two different points.

[0078] Opposing wrapping material surfaces are separated from each other by the fiber carpet, specifically in the area of ​​the unembossed and the embossed fiber carpet. This means that opposing wrapping material surfaces are spaced apart from each other and only touch in the area of ​​the sealing surfaces to form the wrapping material.

[0079] To effectively prevent thermal bridges, the weight per unit area of ​​the fiber carpet can be consistent across the entire fiber carpet. For example, a weight per unit area in the first fiber carpet thickness area corresponds to a weight per unit area in the second fiber carpet thickness area.

[0080] The fiber carpet is preferably free of adhesives.

[0081] The embossed insulating packaging preferably has a first fiber carpet thickness of 20 mm to 25 mm with a standard basis weight between 800 g / m 2 and 1350 g / m 2 , preferably between 1200 g / m 2 and 1300 g / m 2 , more preferably 1250 g / m 2 . In another embodiment, the embossed insulating packaging may preferably have a first fiber carpet thickness of 25 mm to 35 mm with a standard basis weight between 1700 g / m 2 and 2000 g / m 2, preferably between 1750 g / m 2 and 1850 g / m 2 , more preferably 1800 g / m 2 Generally speaking, the embossed insulating packaging can have a standard basis weight of at least 800 g / m 2 , at least 1000 g / m 2 or at least 1200 g / m 2 and / or a standard basis weight of maximum 2000 g / m 2 , maximum 1800 g / m 2 or a maximum of 1600 g / m 2 have.

[0082] To effectively avoid thermal bridges, a first density of the fiber carpet in the region of the first fiber carpet thickness can be at least 25% lower than a second density in the region of the second fiber carpet thickness, preferably at least 35% lower, more preferably at least 50% lower.

[0083] This means that in the area of ​​the larger first fiber carpet thickness, the density, i.e., the weight of the fiber carpet per unit area, is greater than in the area of ​​the smaller second fiber carpet thickness. The density in the area of ​​the second fiber carpet thickness can, for example, be more than 100%, preferably more than 200%, and more preferably more than 300% greater than in the area of ​​the first fiber carpet thickness. Due to the embossing or compression of the fiber carpet, its fiber carpet thickness is reduced and its density increased.

[0084] The aforementioned devices, system, and / or units can each comprise dedicated control units and / or controllers. Alternatively or additionally, at least one control unit and / or controller can be provided that controls at least two and / or more of the aforementioned devices and / or units. Furthermore, one or more control units and / or controllers can be arranged hierarchically, so that, for example, one control unit and / or controller controls multiple control units and / or controllers in order to control the functions of multiple devices and / or units. The system preferably comprises a control unit for controlling all of the units and / or devices and / or elements and / or controllers and / or control units comprised thereby.

[0085] The fiber carpet can be continuous in its embossed / creased area. A continuous design means that the fiber carpet runs continuously in the embossed / creased area, i.e., the fiber carpet is a fiber composite made of cellulose fibers without interruption. In this way, the fiber carpet can preferably also perform its insulating function in the embossed / creased area. The embossed insulating packaging can be inserted into an outer packaging. For this purpose, the embossed insulating packaging can be folded at the embossing. The embossing can be such that it corresponds to an inner edge of the outer packaging, while unembossed areas can lie against the inner surfaces of the outer packaging.

[0086] The paper layer can comprise kraft paper, which is preferably coated with a sealable plastic layer. The plastic layer is made of polyethylene, for example. Kraft paper is understood to be a type of paper that consists of more than 90%, preferably more than 95%, more preferably more than 98%, cellulose fibers. Starch, alum, and / or glue can be added to achieve surface effects and increase strength. The paper layer is preferably coated on one side with plastic, e.g., polyethylene (PE). The plastic coating can enable an airtight closure of the wrapping material. In addition, the paper layer can be made water-repellent thanks to the plastic coating.

[0087] In an environmentally friendly embodiment, the paper layer can comprise unbleached paper. Furthermore, the paper layer can be heat-sealable, making it particularly suitable for processing into a sealed bag with sealing sections. Preferably, the paper layer has a water vapor barrier that protects the filling from water absorption.

[0088] In one embodiment, the paper layer has a weight between 67 g / m 2 and 77 g / m 2 , preferably between 69 g / m 2 and 75 g / m 2 , more preferably between 71 g / m 2 and 73 g / m 2Furthermore, in one embodiment, the paper layer has a thickness between 92 µm and 102 µm, preferably between 94 µm and 100 µm, more preferably between 96 µm and 98 µm. The weight is preferably determined according to ISO 536. The thickness is preferably determined according to ISO 534. Furthermore, the paper layer can have a tensile strength MD of 5.4 kN / m (according to ISO 1924) and / or a tensile strength CD of 2.3 kN / m (according to ISO 1924). Furthermore, the paper layer can have a tear strength MD of 550 mN (according to ISO 1974) and / or a tear strength CD of 790 mN (according to ISO 1974). Furthermore, the paper layer can have a bursting strength of 370 kPa (according to ISO 2758). Furthermore, the paper layer can have an absorbency with a Cobb value of 32 g / m 3 (according to ISO 535). Furthermore, the paper layer can have a water vapor transmission rate (WVTR) of 3.2 g / (m 2*24h) (according to ASTM 1249). The above paper properties represent an optimal balance between low material usage, good processability of the paper layer, and a strength suitable for use as an insulating material.

[0092] An embossed insulating packaging 10 is shown schematically in Fig. 1. The embossed insulating packaging 10 comprises a wrapping material 12, which is formed into a sealed bag by means of at least one longitudinal seam 14 and at least two transverse seams 15. The seams are in Fig. 1 as thick dashed lines. The longitudinal seam 14 runs longitudinally and connects the wrapping material 12 to form a tube, which is closed at two opposite ends by means of the two transverse seams 15. In the illustrated embodiment, the wrapping material 12 is a plastic-coated paper layer coated with a plastic layer of polyethylene and heat-sealable, or a heat-sealable plastic layer.

[0093] The wrapping material 12 contains a filling comprising a fiber carpet 16 made of cellulose fibers. The fiber carpet 16 is Fig. 1 by dashed lines and is completely surrounded by the wrapping material 12. A continuous length 18 of the fiber carpet 16 is more than 60 cm, preferably more than 70 cm, more preferably more than 80 cm. A continuous width 20 of the fiber carpet 16 is more than 20 cm, preferably more than 30 cm, more preferably 40 cm or more. Furthermore, the fiber carpet 16 can have a continuous length 18 of more than 100 cm, preferably more than 150 cm, more preferably more than 180 cm, even more preferably 200 cm or more. Furthermore, the fiber carpet 16 can have a continuous width 20 of more than 50 cm, preferably 60 cm or more.

[0094] Embossments 22 of the embossed insulating packaging 10 are in Fig. 1 by means of thick, continuous transverse lines. The embossed insulating packaging 10 comprises at least one embossing 22, which can run transversely, longitudinally, or diagonally as desired. The embossing 22 is provided in the region of the fiber carpet 16. The embossing 22 is visible in the wrapping material 12; for example, the wrapping material 12 can be embossed in such a way that it is deformed in the region of the embossing 22. Fig. 2a and Fig. 2b show examples of an embossed insulating packaging 10 with one embossing 22a or two embossings 22b, each extending transversely to the longitudinal extent of the embossed insulating packaging 10. It can be seen that the embossings 22, 22a, 22b are clearly visible in the form of a notch 24 on the wrapping material 12.

[0095] The Fig. 3a and Fig. 3b show a longitudinal section through the Fig. 2b shows the embossed insulating packaging 10 in two different views with different degrees of abstraction. The embossing of the fiber carpet 16 creates an embossed region 26 that is compressed compared to an unembossed region 28, i.e., at least one spatial extent of the fiber carpet 16 is reduced by means of the embossing 22. Consequently, the embossed insulating packaging 10 has a first fiber carpet thickness 30 in the unembossed region 28 that is greater than a second fiber carpet thickness 32 in the embossed region 26. The regions 26, 28 can be directly adjacent to one another or spaced apart from one another by means of a transition region in which the fiber carpet thickness increases. The embossing 22 can serve as a defined kink point for the embossed insulating packaging 10. Fig. 4 shows the embossed insulating packaging 10 with one or two embossments 22, 22a, 22b, wherein the embossed insulating packaging 10 is bent according to the embossment 22, 22a, 22b.

[0096] In the following, the Fig. 5 to 8, a system for producing an insulating packaging, for example the insulating packaging 10, is explained using an embodiment.

[0097] The system 34 for producing the embossed insulating packaging 10 comprises a Fig. 5, which is movably attached to the device frame 38 by means of a displacement device 37. The system 34 further comprises a further embossing tool 40, which in the illustrated embodiment is fixedly connected to the device frame 38. The embossing tool 36, 40 comprises a first embossing unit 42 and a second embossing unit 44. When both embossing units 42, 44 are at their maximum distance from each other, they are in an open position. For embossing, the first embossing unit 42 is moved towards the second embossing unit 44 and / or the second embossing unit 44 is moved towards the first embossing unit 42. For clarity, Fig. 5 an intermediate position in which the first embossing unit 42 has already moved towards the second embossing unit 44, but the second embossing unit 44 is still in the open position.

[0098] The system 34 further comprises a transport device 46, which in the illustrated embodiment comprises a plurality of belts 48. The transport device 46 runs over at least one deflection roller 49, which is attached to the device frame 38. For the precise positioning of the belts 48 of the transport device 46, at least one guide rod 50 is provided, which defines the positioning of the belts 48 perpendicular to its transport direction 52.

[0099] The embossing tool 36, 40 has at least one recess 54 into which a portion of the transport device 46, in particular a portion of the belt 48, engages. In the illustrated embodiment, the at least one recess 54 is provided in the first embossing unit 42. As shown in Fig. 5, the part of the transport device 46 engages in the at least one recess 54 when the first embossing unit 42 is in its embossing position, ie is moved towards the second embossing unit 44 and / or the part of the transport device 46 engages in the at least one recess 54. Even if this is not apparent in the figures, the transport device 46 is disengaged from the first embossing unit 42 when the first embossing unit 42 is in the open position. In the view of Fig. 5, in the open position of the first embossing unit 42 (not shown), the transport device 46 would be arranged vertically above the first embossing unit 42.

[0100] The sequence of an embossing process is described in detail below. First, an insulating packaging is positioned on the transport device 46 such that the transport device 46 holds the insulating packaging. The insulating packaging is then positioned relative to the embossing tool 36, 40 by means of the transport device 46, i.e. the insulating packaging is located between the first embossing unit 42 and the second embossing unit 44. The embossing units 42, 44 are then moved into the embossing position, i.e. they move towards one another. While the first embossing unit 42 moves into the embossing position, the transport device 46 engages in the at least one recess 54 of the first embossing unit 44 and the first embossing unit 44 slightly lifts at least one section of the insulating packaging to be embossed. The section of the insulating packaging to be embossed is consequently detached from the transport device 46.

[0101] For moving the first embossing unit 42, a first movement device 56 is provided and for moving the second embossing unit 44, a second movement device 58 is provided, which is best shown in Fig. 6. The first and second movement devices 56, 58 comprise a pressure cylinder for applying pressure to move the first and second embossing units 42, 44 toward one another. In a specific exemplary embodiment, an embossing pressure of approximately 6 bar is exerted. However, embossing pressures between 6 bar and 10 bar, preferably between 4 bar and 8 bar, are also possible. An embossing time can last approximately 1 second. However, embossing times between 0.5 seconds and 2 seconds are also possible. An end position sensor and a pressure sensor of the system 34 for monitoring the embossing process can be provided.

[0102] After the insulating packaging 10 has been embossed for a predetermined embossing time and under an embossing pressure, the embossing tool 36, 40 is moved into the open position and the embossed insulating packaging 10 is moved out of the embossing tool 36, 40 by means of the transport device 46 and leaves the system 34. The insulating packaging or embossed insulating packaging 10 is thus held by the transport device 46 during embossing. By means of the at least one recess 54 in the embossing tool 36, 40, it is possible to enable the embossing process while the insulating packaging 10 is held by the transport device 46, whereby precisely one transport device 46 is provided for feeding, embossing, and transporting the insulating packaging 10.

[0103] Fig. Figure 7 shows an embossing station 59, which includes the embossing tool 36, 40 and the movement devices 56, 58. In the illustrated embodiment, the first embossing unit 42 has four recesses 54. Each recess 54 is formed by two spaced-apart embossing members 60. It is understood that more or fewer recesses 54 or more or fewer embossing members 60 may be present.

[0104] The first embossing unit 42, for example a first embossing die, has a V-shaped recess 62, as shown in Fig. 8. An interior angle α of the V-shaped recess 62 is between 60° and 100°. The second embossing unit 44, for example a second embossing die, has a V-shaped projection 64, as also shown in Fig. 8. Legs of the V-shaped projection 64 can enclose an angle β between 60° and 100°. In the illustrated embodiment, the V-shaped recess 62 of the first embossing unit 42 has an interior angle α of 100° and the legs of the V-shaped projection 64 of the second embossing unit 44 enclose an angle of 90°. A leg length 66 of the V-shaped projection 64 can be 40 mm long. An opening width 68 of the V-shaped recess 62 can be 50 mm wide, measured from the open ends of the "V". The V-shaped recess 62 can have an opening depth 70 between 19 mm and 20 mm, measured from the tip to the opening of the "V". The first embossing unit 42 can be made of aluminum. The second embossing unit 44 can be made of steel (e.g. structural steel such as S235jr).

[0105] Process steps for producing an embossed insulating packaging 10, for example the embossed insulating packaging 10, are described in Fig.9 is shown as a flow chart. In step S10, an insulating packaging is provided which comprises at least one region to be embossed. The method further comprises step S20, in which the insulating packaging is positioned relative to the embossing tool 36, 40. The transport device 46 can be used for this purpose. This is followed by a step S30, in which the embossing tool 36, 40 is moved into an embossing position. In the embossing position, an embossing pressure is applied to the insulating packaging by means of the embossing tool 36, 40 for a predetermined embossing time, so that the fiber carpet 16 is compressed in the engagement region of the embossing tool 36, 40 in step S40. In a step S50, the embossing tool 36, 40 is moved into an open position and in a step S60, the embossed insulating packaging 10 is removed from the embossing tool 36, 40 by means of the transport device 46.This can be followed by a step S70 in which the embossed insulating packaging 10 is folded in such a way that the embossing 22, 22a, 22b defines the fold line.
