Description

[0001] Method for producing an embossed insulating package, plant for producing an embossed insulating package and embossed insulating package

[0002] The invention relates to a method for producing an embossed insulating package, a system for producing an embossed insulating package and an embossed insulating package.

[0003] Insulated packaging made of expanded polystyrene (EPS) is known from the prior art, enabling the mobile cooling of products. The products to be cooled are placed in a container, usually a rectangular EPS box, along with a cooling medium such as ice packs or dry ice, and sealed with a removable EPS lid. Depending on the cooling capacity of the medium, the products can be kept cool for several hours, or even up to several days, for example, two. The EPS box with the lid closed can then be placed in a shipping carton and sent.

[0004] In many cases, when shipping refrigerated products such as food or medication, the insulating packaging is disposed of after use. From an environmental perspective, recycling insulating packaging is preferable. However, established recycling processes for EPS materials are lacking, particularly for private households. Furthermore, EPS is a mineral material, making its recycling an energy-intensive process. Consequently, using EPS as insulating packaging is associated with high production and recycling costs.

[0005] A more environmentally friendly solution for insulated packaging is available from the

[0006] German patent application DE 10 2022 1 19 517 A1 discloses an insulating packaging made of recycled paper that can be used to insulate cooling containers. The insulating packaging is long enough to be inserted into a cardboard box in a curved shape, covering at least one edge and one side of the cardboard box. Covering the edges of a cardboard box used as a cooling container is particularly important for the insulating effect, as thermal bridges often form at edges, reducing the insulating effect.

[0007] Therefore, there is a constant effort in the production of insulated packaging to avoid thermal bridges, especially in the area of ​​the edges of a refrigerated container. This is accompanied by the pursuit of technical solutions to provide insulated packaging in which any potential thermal bridges are reproducibly avoided.

[0008] Based on the prior art, the invention aims to enable the reproducible production and use of insulating packaging while avoiding thermal bridges.

[0009] This problem is solved according to the invention by the subject matter of the independent claims. Further developments are described in the dependent claims.

[0010] A method for producing an embossed insulating package is described, comprising the following steps: providing an insulating package comprising cellulose fibers forming a fiber mat and surrounded by wrapping material; and embossing the insulating package.The embossing of the insulating packaging comprises the steps of positioning the insulating packaging relative to an embossing die by means of a transport device; moving the embossing die and / or the transport device into an embossing position; applying embossing pressure to the insulating packaging by means of the embossing die and remaining in the embossing position with the embossing pressure exerted for a predetermined embossing time, so that the fiber mat in the engagement area of ​​the embossing die is compressed; moving the embossing die and / or the transport device into an open position; and removing the embossed insulating packaging from the embossing die by means of the transport device. The foregoing process steps are preferably carried out in the order listed.

[0011] This process creates a defined embossing on the insulating packaging, characterized by a clear and defined embossing line. Consequently, the process can be used to produce embossed insulating packaging with a defined embossing and 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, as used here, is understood as the movement of connected surfaces towards each other, such that the surfaces enclose an angle of less than 180 degrees. The apex of this angle can be formed by the embossing or embossing line, or the crease / fold line. By embossing the insulating packaging, it can be ensured that the packaging retains its insulating properties in the crease / fold area and that thermal bridges are avoided.In the following, the synonymous terms "folding" and "creasing" are summarized under the term "creasing" and its declined uses.

[0012] The step of removing the embossed insulating packaging from the embossing die can be followed by a step of folding the embossed insulating packaging, with the embossing defining the fold point. The embossing can create a fold that can be reproduced in the insulating packaging. The folded and embossed insulating packaging can then be placed, for example, into an outer packaging, such as a carton. The defined fold of the embossed insulating packaging, made possible by the embossing, simplifies the alignment of the insulating packaging relative to the outer packaging. The embossing or fold point can be located adjacent to an inner edge of the outer packaging, while the side surfaces of the outer packaging and the embossed insulating packaging are opposite each other.The defined creases created by the embossing process can therefore reduce the number of steps required to align the embossed insulating packaging with the outer packaging. Furthermore, these defined creases prevent the embossed insulating packaging from shifting within the outer packaging, thus preventing the formation of unwanted thermal bridges.

[0013] The creation of at least one embossed line in the insulating packaging, resulting in a defined crease, can be achieved using an automated process. Similarly, the folding of the embossed insulating packaging can be automated, with the embossed line forming the crease line. This simplifies the reproducible production of embossed insulating packaging that consistently avoids thermal bridges.

[0014] The insulating packaging, in its embossed or unembossed form, preferably comprises a covering material and a filling in the form of a fiber mat. The fiber mat is preferably continuous. The covering material preferably forms a sealed bag that completely surrounds the fiber mat. The covering material comprises, for example, a plastic-coated paper layer that forms a sealed bag by creating at least one sealing section. The covering material is preferably free of adhesives, apart from an optional sealing layer for sealing the covering material. Opposing surfaces of the covering material are completely separated from each other by the fiber mat, both in the unembossed and embossed areas. That is, opposing surfaces of the covering material are spaced apart and only touch in the area of ​​the sealing surfaces that form the covering material.

[0015] The fiber carpet can have a continuous length of more than 60 cm, preferably more than 70 cm, and more preferably more than 80 cm, and a continuous width of more than 20 cm, preferably more than 30 cm, and more preferably 40 cm or more. The cellulose fibers of the fiber carpet are, for example, loosely bonded together, i.e., without adhesive. The fiber carpet can have a continuous length and width, i.e., it contains no defects that could cause thermal bridges.

[0016] 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 emissions are significantly reduced compared to the use of EPS. Furthermore, the use of cellulose fibers enables energy-efficient production, reducing energy consumption to 5 to 10% compared to the production of conventional EPS insulating packaging. Recycling materials made from cellulose fibers is also very simple. They can be disposed of like waste paper, for which established recycling processes exist for both private households and industrial applications.

[0017] 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 known blown-in insulation materials with a thermal conductivity of 40 mW / m*K (lambda) and is approximately the same as that of EPS.

[0018] Particularly low thermal conductivity can be achieved with cellulose fibers when they are short and thin. Shorter, thinner fibers are more flexible, resulting in more homogeneous cellulose materials with a uniform pore size distribution. Longer fibers, on the other hand, can have less uniform air inclusions, leading to an inhomogeneous density distribution and fluctuating mass distribution in the longitudinal and transverse directions. This can create thermal bridges, which in turn increase thermal conductivity.

[0019] Furthermore, it has been shown that low fiber fibrillation—fibrils being fine hairs on the fiber surface that point into the surrounding space and can come into contact with other fibers—can be advantageous 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 encapsulation.

[0020] In some embodiments, the cellulose fibers are provided by breaking down comminuted cellulose materials comprising cellulose fibers. Preferably, comminuted cellulose materials are obtained by comminuting cellulose materials. The cellulose fibers are processed into a fiber mat, for example according to a method described in DE 10 2022 1 19 517 A1.

[0021] Cellulose material can include paper, cardboard, waste paper, and newspapers. Furthermore, the term "cellulose material" encompasses all materials consisting primarily of cellulose fibers. For example, recycled B12 waste paper can be used. B12 waste paper or mixed paper consists of newspapers, cardboard, and writing paper, preferably containing no more than 40% newspapers or magazines.

[0022] The embossed insulating packaging produced by the above method preferably has a thickness of 20 mm to 25 mm and a standard basis weight of between 800 g / m². 2 and 1350 g / m² 2 , preferably between 1200 g / m² 2 and 1300 g / m² 2 , further preferred from 1250 g / m² 2In 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 / m² 2 and 2000 g / m² 2 preferably between 1750 g / m² 2 and 1850 g / m² 2 , further preferred from 1800 g / m² 2 Generally speaking, the insulating packaging can have a standard basis weight of at least 800 g / m². 2 , at least 1000 g / m² 2 or at least 1200 g / m² 2 and / or a standard basis weight of no more than 2000 g / m² 2 , maximum 1800 g / m² 2 or at most 1600 g / m² 2The wrapping material preferably completely surrounds the fiber mat. In the embossed insulating packaging, the wrapping material is preferably completely sealed. The wrapping material preferably has a pouch shape with three closed sides and a filling opening when the cellulose fibers are introduced and / or when the fiber mat is formed. It can be sealed, for example, by sealing seams at both longitudinal ends and a sealing 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 pouch made of wrapping material is therefore preferably airtight.

[0023] The encapsulation material preferably remains undamaged by the embossing process. It may undergo a change in shape in the embossed area, which, however, may be temporary. It is conceivable that the change in shape of the encapsulation material decreases over a longer period, even a year or more. The change in shape may be visible to the naked eye. The encapsulation material may exhibit an indentation caused by the embossing, for example, a V-shaped indentation. The material structure of the encapsulation material preferably remains unchanged by the embossing. In other words, the pressure or force applied to the encapsulation material by the embossing process leads, for example, to the change in shape of the encapsulation material in the embossed area.

[0024] The fiber mat preferably remains undamaged by the embossing process. It experiences compression in the embossed area, which, however, may be temporary. It is conceivable that the compression of the fiber mat decreases over a longer period, even a year or more, and with corresponding agitation. The change in shape may be visible to the naked eye (when the sheathing material is removed). The fiber mat may exhibit an indentation caused by the embossing, for example, a V-shaped indentation. The fiber mat retains its continuous length and width during the process; only its thickness is altered in the embossed area. In other words, the pressure or force applied to the fiber mat by the embossing process leads, for example, to the compression and change in shape of the fiber mat in the embossed area.

[0025] The embossed insulating packaging provides insulation in both the embossed and unembossed areas. The fiber mat can be folded along the embossing / embossing line while retaining its insulating properties. Thermal conductivity may be slightly higher in the embossed area than in the adjacent unembossed areas of the fiber mat. However, thermal conductivity in the embossed area is such that no thermal bridges exist. Consequently, undesirable thermal bridges are avoided. The fiber mat is not damaged, for example, by the embossing process (i.e., its compression) and subsequent folding. The fiber mat can be compressed but maintain its continuous length and width without defects.

[0026] The transport device can move the insulating packaging in one direction. The insulating packaging is held in place 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 direction of the horizontal extent of the transport device.

[0027] The process step of positioning the insulating packaging can be carried out by moving the packaging, held by the transport device, to the embossing tool. A position sensor can detect when the insulating packaging is in a working position. For example, two position sensors can be provided, whereby 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.

[0028] The process of moving the embossing tool and / or the transport device into the embossing position can be carried out by means of a moving device, which is, for example, driven by compressed air. Furthermore, the moving device can be configured to apply the embossing pressure, which is applied to the insulating packaging by the embossing tool, and / or 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, and 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.According to an advantageous embodiment, the embossing steps of the insulating packaging can be performed while the insulating packaging is held by a transport section of the transport device. The embossing steps of the insulating packaging include, for example, the following: 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 embossing pressure to the insulating packaging by means of the embossing tool and retaining the embossing tool in the embossing position while exerting the embossing pressure for a predetermined embossing time, so that the fiber mat in the engagement area of ​​the embossing tool is compressed; moving the embossing tool and / or the transport device into an open position; and moving the embossed insulating packaging out of the embossing tool by means of the transport device.In this way, the embossing process is carried out efficiently. Transferring the insulating packaging between its unembossed and embossed states is not required, resulting in a short processing time. Additional steps for transferring the insulating packaging from, for example, one conveyor belt to another are eliminated. The transport device can be in an embossing position when it engages in at least one recess of the embossing tool. Likewise, the transport device can be in an open position when it is not engaged in at least one recess of the embossing tool.

[0029] 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 engage 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 designated for embossing. The area designated for embossing is the area where the embossing mark is applied after the embossing process. During lifting, the insulating packaging can detach from the transport device, at least in the area designated 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 designated for embossing by between 10 mm and 100 mm, preferably between 15 mm and 80 mm, and more preferably between 15 mm and 50 mm.In one exemplary embodiment, the insulating packaging can be raised between 20 mm and 30 mm. The embossing is preferably carried out at room temperature. Cooling or heat input during the embossing process is unnecessary.

[0030] In the stamping position, a portion of the transport device can be located in at least one recess of the stamping die. During stamping, the transport device can engage in at least one recess of the stamping die. The transport device can engage in at least one recess of the stamping die when the stamping die is moved into the stamping position, and / or when the transport device is moved relative to the stamping die into the stamping position. When the stamping die is moved into the open position, and / or when the transport device is moved relative to the stamping die into the open position, the transport device can disengage from the stamping die. A movement of the transport device comprises a traversing movement of the transport device corresponding to a path of movement of the stamping die, and / or a movement transverse to this path, and / or a movement in the direction of transport.

[0031] In one embodiment, the embossing tool can comprise a first embossing unit and a second embossing unit that interacts with the first. The first embossing unit can include at least one recess. For example, a section of the transport device engages in the at least one recess of the first embossing unit. This technical solution can ensure that the insulating packaging is held by the transport device in its embossed and unembossed states, as well as during the embossing process steps, thereby achieving a short processing time.

[0032] The process of moving the embossing tool and / or the transport device into an embossing position can be accomplished by means of the following sub-steps: actuating 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; actuating the second embossing unit to move it from the open position into the embossing position, with the actuating of the second embossing unit occurring sequentially after the actuating of the first embossing unit; and moving the second embossing unit relative to and in the direction of the insulating packaging. While the embossing tool remains in the embossing position under embossing pressure for a predetermined embossing time, the first and second embossing units are spaced apart from each other by a defined embossing distance.The distance between the first and second embossing units can be monitored using an end-position sensor. The defined embossing distance enables reproducible pressure application during the embossing process.

[0033] According to a further aspect of the invention, the aforementioned problem is solved 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 later. Furthermore, the system can, for example, be used to produce an embossed insulating package manufactured according to the aforementioned method.

[0034] The system for embossing an insulated package comprises a fixture frame and at least one embossing station attached to the fixture frame. The embossing station includes an embossing die, which is designed with at least one recess, and a movement device for moving the embossing die between an open position and an embossing position, wherein the embossing die is configured to emboss the insulated package in the embossing position. The system further comprises a transport device attached to the fixture frame for transporting the insulated package relative to the embossing station, wherein a transport section of the transport device is configured to feed the insulated package to the embossing station, hold it during an embossing process, and transport it out of the embossing station. In the embossing position, at least a portion of the transport section is located in the area of ​​the at least one recess of the embossing die.

[0035] The advantages previously outlined for the process are achieved analogously with the system defined above. The system enables the reproducible production of an embossed insulating package with a clearly defined embossing or embossing line that allows for folding along the embossing and prevents the formation of a thermal bridge in the fold area. The embossing line can therefore represent the fold line. Furthermore, the system ensures an efficient and short process time by incorporating a transport device to hold the insulating package during the embossing process, as well as during feeding the package to the embossing tool and during the removal of the embossed package.

[0036] The properties of the wrapping material, the fiber mat and the embossed insulating packaging mentioned at the beginning in relation to the first aspect of the invention apply equally to the second aspect of the invention.

[0037] The insulating packaging, or the embossed insulating packaging, is moved in a transport direction relative to the embossing station. This transport direction can be along the longitudinal extent of the transport device. The transport direction can always be the same; that is, the transport direction can be the same when positioning the insulating packaging relative to the embossing tool and when removing the embossed insulating packaging from the embossing tool.

[0038] The embossing station can be slidably mounted on the fixture frame to allow movement in and against the direction of transport. This allows the position of the embossing relative to the fixture frame to be adjusted. The system preferably has two embossing stations, which can be identical. For example, one of the two embossing stations can be fixed to the fixture frame, while the other can be slidably mounted. Alternatively, both embossing stations can be slidably mounted on the fixture frame to increase the system's flexibility. The slidability of at least one of the embossing stations allows for the creation of different embossing patterns.

[0039] For a compact design of the system, the transport device can be fixed to the fixture frame. Alternatively, the transport device can be mounted on the fixture frame with adjustable height. For example, the transport device can be rotatably mounted to the fixture frame by means of deflection elements. The deflection elements can be driven by a motor. Consequently, the transport device can be movable around the deflection elements and have a circumferential shape. The deflection elements can, for example, be guide rollers. A transport section of the transport device, on which the insulating packaging is held, moves in the transport direction. For example, the transport device comprises at least two circumferential belts designed to hold the insulating packaging. A section of a belt of the transport device can engage in at least one recess of the embossing tool.The deflection elements (e.g., pulleys) can hold the at least two circulating belts. For example, the transport device comprises three circulating belts, preferably four, which are designed to hold the insulating packaging. A belt can be understood to be an element whose longitudinal extent is significantly greater than its width. For example, a belt width of less than or equal to 2 cm.

[0040] The belts can be guided by means of guide elements, e.g. guide rods. The belts can be attached to the device frame in such a way that their distance from each other can be adjusted.

[0041] A transport section of the transport device corresponds to the outer dimensions of the insulating packaging in at least one dimension, for example, its longitudinal extent. The transport section of the transport device preferably runs horizontally. This ensures that the insulating packaging is held securely in both its embossed and unembossed states.

[0042] The embossing tool can comprise a first embossing unit and a second embossing unit that interacts with the first. The first and second embossing units can be movable relative to each other to assume an embossing position, in which the first and second embossing units are moved towards each other, and an open position, in which the first and second embossing units are spaced apart sufficiently to allow the insulating packaging to move 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 area of ​​the at least one recess of the first embossing unit.

[0043] Alternatively or additionally, the moving device can be configured to move at least one of the first and second embossing units relative to the other between the embossing position and the open position, wherein the first and second embossing units are configured to emboss the insulating packaging in the embossing position. According to one embodiment, an adjusting device, e.g., a height-adjusting device, of the transport device can move the insulating packaging into the embossing position while the first embossing unit remains stationary. The embossing can be carried out by moving the second embossing unit into the embossing position relative to the first embossing unit.

[0044] A space-saving solution can involve arranging the first embossing unit 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 also be moved relative to the transport device by means of the movement device.

[0045] The first embossing unit can comprise at least one recess. More specifically, 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 extent by the at least one recess. Consequently, the first embossing unit can comprise at least two separate embossing elements. In one embodiment, for example, the embossing unit comprises four recesses and five embossing elements. An embossing surface of the second embossing unit can be continuous.

[0046] 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 emboss insulated packaging with a transverse extent of up to 65 cm, preferably up to 75 cm, and more preferably up to 85 cm or greater.

[0047] According to a preferred embodiment, the first embossing unit and / or the second embossing unit is 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 essentially perpendicular to each other. The extent of the embossing units can be determined by their path of movement when at least one of the first and second embossing units is moved into the embossing position and / or the open position. An embossing suitable for folding 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.

[0048] The insulating packaging can be pressurized during embossing using compressed air. In one embodiment, the moving device can be actuated by compressed air. The moving device preferably comprises a first moving device for moving the first embossing unit and a second moving device for moving the second embossing unit.

[0049] The moving device can be configured to exert a stamping pressure between 2 bar and 10 bar, preferably between 4 bar and 8 bar, and more preferably between approximately 6 bar. The moving device can be configured to maintain the stamping pressure for a stamping time between 0.5 seconds and 2 seconds, preferably 1 second.

[0050] For the reproducible production of an embossed insulating package, the system can further include at least one position sensor configured to detect the position of the insulating package. For example, the device can include two position sensors, wherein when a first position sensor detects the insulating package, the speed of the transport device is reduced, and when a second position sensor detects the insulating package, the transport device is stopped.

[0051] 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 system may also 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.

[0052] The device can include at least one pressure sensor configured to detect the embossing pressure applied by the first and second embossing units. This allows the embossing process to be monitored. The device can also include 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.

[0053] According to a further aspect of the invention, the aforementioned problem is solved by an embossed insulating package. The insulating package is preferably manufactured using a method according to the first aspect of the invention. The insulating package is preferably manufactured using a system according to the second aspect of the invention. The embossed insulating package comprises a wrapping material comprising a paper layer (e.g., coated with plastic) which forms a pouch by forming at least one composite section (e.g., a sealing section), and a filling comprising a fiber mat of cellulose fibers. The fiber mat 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 thickness in an unembossed area and a second fiber thickness in an embossed area. The second fiber thickness is at least 20%, preferably at least 30%, and more preferably at least 50% less than the first fiber thickness.

[0054] The properties of the wrapping material, the fiber mat and the embossed insulating packaging mentioned at the beginning in relation to the first aspect of the invention apply equally to the third aspect of the invention.

[0055] Embossing on insulated packaging can define a fold or crease line. The embossing can define an embossing line. The embossing line can represent the crease or fold line.

[0056] The fiber carpet thickness, for example, refers to the extent of the fiber carpet in a direction that runs perpendicular to the longitudinal and transverse extent of the fiber carpet.

[0057] The first fiber mat thickness is preferably between 15 mm and 35 mm, more preferably between 20 mm and 30 mm, and more preferably between 20 mm and 25 mm. The second fiber mat thickness is preferably between 3 mm and 15 mm, more preferably between 5 mm and 12 mm, and more preferably between 7 mm and 10 mm. In this way, thermal bridges can be effectively avoided, even if the embossed insulating packaging is folded in the embossing area.

[0058] A longitudinal extent of the embossing, i.e. a longitudinal extent 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.

[0059] In one possible embodiment, at least one of the widths and the length of the continuous fiber mat is at least 60 cm. Furthermore, the width of the fiber mat can be between 55 and 65 cm, preferably 60 cm. Additionally, the length of the fiber mat can be between 30 cm and 200 cm, or more than 200 cm. Larger dimensions of the fiber mat allow the embossed insulating packaging to be used with few or no thermal bridges. If the fiber mat 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.

[0060] The wrapping material can, for example, form a completely sealed bag using sealing sections. One of the sealing sections can connect two opposite ends of the wrapping material, creating a wrapping material tube with a circumferentially closed outer surface. Another sealing section can close the wrapping material tube to form an open bag. A further sealing section can close the bag open at one end to form a completely sealed bag. Other sealing sections are also conceivable, as long as a completely sealed bag is formed in which the fiber mat can be contained. The bag is preferably airtight.

[0061] The fiber mat is continuous. That is, the fiber mat is preferably continuous along its length and width. Furthermore, the casing material is preferably continuous. That is, the casing material preferably has no division into compartments or quilted seams. In other words, the bag formed from the casing material comprises exactly one chamber for receiving the filling, i.e., the fiber mat. Advantageously, the second fiber mat thickness is achieved by compressing the fiber mat. In other words, a compression method can be used to achieve the reduced second fiber mat thickness. A possible method for compressing the fiber mat 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 methods 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 surrounding covering material.

[0062] The embossing of the insulated packaging can be visually discernible to the naked eye, which simplifies the subsequent folding of the embossed packaging. For example, the outer material adjacent to the embossed fiber mat can be embossed in such a way that the outer material exhibits a deformation at the embossing point. This deformation can be a V-shaped indentation. A semicircular or angular indentation in the outer material is also possible. The shape of the indentation is essentially determined by the shape of the embossing tool used.

[0063] For a reproducible crease in the embossed insulating packaging, it has proven advantageous if the embossing runs along a straight line.

[0064] Generally, the embossing line follows the shape of the embossing tool and its orientation relative to the insulating packaging during the embossing process. Straight embossing lines are preferred. The embossing line can be perfectly straight, i.e., free of deviations such as lateral grooves that deviate from a straight line. The embossing line can represent a defined and reproducible crease point in the embossed insulating packaging. The embossing line can be free of breaks.

[0065] The application of a defined embossing / embossing line increases the reproducible folding of the embossed insulating packaging. Furthermore, the embossing prevents the fiber mat from breaking at a fold point, i.e., from interrupting the continuous length and width of the fiber mat at certain points. This risk exists if the continuous fiber mat is folded without a prior embossing line along which the fiber mat is compressed. In other words, without a defined embossing line as a fold point, the continuous fiber mat can tear, potentially creating an undesirable thermal bridge. Moreover, folding the fiber mat without prior embossing does not achieve the desired compression of the fiber mat in the fold area, making the insulation in the fold area inconsistent.If the insulating packaging is folded without prior embossing, the crease is not reproducible and does not show a straight, clearly defined crease line, but rather a curve with a broken crease line. It goes without saying that this is difficult to reproduce and consequently makes it harder to insert into outer packaging.

[0066] Two embossing lines can run parallel to each other, so that the embossed insulating packaging can be reproducibly folded at two different points.

[0067] Opposing surfaces of the encapsulation material are separated from each other by the fiber mat, specifically in the area of ​​the unembossed and the embossed fiber mat. This means that opposing surfaces of the encapsulation material are spaced apart and only touch in the area of ​​the sealing surfaces to form the encapsulation material.

[0068] To effectively prevent thermal bridges, the weight of the fiber carpet per unit area can be kept constant across the entire carpet. For example, the weight per unit area in the first fiber carpet thickness is the same as the weight per unit area in the second fiber carpet thickness.

[0069] The fiber carpet is preferably free of adhesives.

[0070] The embossed insulating packaging preferably has a first fiber mat thickness of 20 mm to 25 mm with a standard basis weight between 800 g / m². 2 and 1350 g / m² 2 , preferably between 1200 g / m² 2 and 1300 g / m² 2 , further preferred from 1250 g / m² 2 In another embodiment, the embossed insulating packaging can preferably have a first fiber mat thickness of 25 mm to 35 mm with a standard basis weight between 1700 g / m². 2 and 2000 g / m² 2 preferably between 1750 g / m²2 and 1850 g / m² 2 , further preferred from 1800 g / m² 2 Generally speaking, embossed insulating packaging can have a standard basis weight of at least 800 g / m². 2 , at least 1000 g / m² 2 or at least 1200 g / m² 2 and / or a standard basis weight of no more than 2000 g / m² 2 , maximum 1800 g / m² 2 or at most 1600 g / m² 2 To effectively avoid thermal bridges, the first density of the fiber mat in the area of ​​the first fiber mat thickness can be at least 25% lower than the second density in the area of ​​the second fiber mat thickness, preferably at least 35% lower, and more preferably at least 50% lower.

[0071] This means that in the area of ​​greater first fiber thickness, the density, i.e., the weight of the fiber carpet per unit area, is greater than in the area of ​​lesser second fiber thickness. The density in the area of ​​the second fiber thickness can, for example, be more than 100%, preferably more than 200%, and more preferably more than 300% greater than in the area of ​​first fiber thickness. Consequently, due to the embossing or compression of the fiber carpet, its thickness is reduced and its density is increased.

[0072] The aforementioned devices, systems, and / or units may each comprise dedicated control units and / or controllers. Alternatively or additionally, at least one control unit and / or controller may 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 may be arranged hierarchically, such that, for example, one control unit and / or controller controls several control units and / or controllers to control the functions of several devices and / or units. The system preferably comprises a control unit for controlling all the units and / or devices and / or elements and / or controllers and / or control units it includes.

[0073] The fiber mat can be continuous across its embossed / folded area. Continuous formation means that the fiber mat runs continuously across the embossed / folded area, i.e., it is a continuous fiber mat made of cellulose fibers. In this way, the fiber mat can preferably maintain its insulating function even in the embossed / folded area. The embossed insulating packaging can be inserted into an outer packaging. For this purpose, the embossed insulating packaging can be folded along the embossing. The embossing can be such that it corresponds to an inner edge of the outer packaging, while unembossed areas can lie against inner surfaces of the outer packaging. The paper layer can comprise kraft paper, which is preferably coated with a sealable plastic layer. The plastic layer is, for example, made of polyethylene.Kraft paper is defined as a type of paper consisting of more than 90%, preferably more than 95%, and more preferably more than 98% cellulose fibers. Starch, alum, and / or sizing may be added to achieve surface effects and increased strength. The paper layer is preferably coated on one side with plastic, e.g., polyethylene (PE). The plastic coating can provide an airtight seal for the packaging material. Furthermore, the plastic coating can make the paper layer water-repellent.

[0074] 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 contents from water absorption.

[0075] In one embodiment, the paper layer has a weight of between 67 g / m². 2 and 77 g / m² 2 , preferably between 69 g / m² 2 and 75 g / m² 2 , preferably between 71 g / m² 2 and 73 g / m² 2 Furthermore, in one embodiment, the paper layer has a thickness between 92 pm and 102 pm, preferably between 94 pm and 100 pm, and more preferably between 96 pm and 98 pm. 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 burst strength of 370 kPa (according to ISO 2758). Furthermore, the paper layer can have an absorbency with a Cobb value of 32 g / m². 3(according to ISO 535). Furthermore, the paper layer can exhibit a water vapor transmission rate (WVTR) of 3.2 g / (m²). 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 durability suitable for use as insulating material.

[0087] Fig. 9 shows a flowchart of a process for manufacturing a

[0088] Insulated packaging.

[0089] An embossed insulating package 10 is shown schematically in Figure 1. The embossed insulating package 10 comprises a wrapping material 12, which is formed into a closed bag by means of at least one longitudinal seam 14 and at least two transverse seams 15. The seams are shown as thick dashed lines in Figure 1. The longitudinal seam 14 runs lengthwise and joins 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, which is coated with a polyethylene plastic layer and heat-sealable, or a heat-sealable plastic layer.

[0090] The casing material 12 contains a filling comprising a fiber mat 16 made of cellulose fibers. The fiber mat 16 is indicated by dashed lines in Figure 1 and is completely enclosed by the casing material 12. The continuous length 18 of the fiber mat 16 is more than 60 cm, preferably more than 70 cm, and more preferably more than 80 cm. The continuous width 20 of the fiber mat 16 is more than 20 cm, preferably more than 30 cm, and more preferably 40 cm or more. Furthermore, the fiber mat 16 can have a continuous length 18 of more than 100 cm, preferably more than 150 cm, more preferably more than 180 cm, and even more preferably 200 cm or more. The fiber mat 16 can also have a continuous width 20 of more than 50 cm, preferably 60 cm or more.

[0091] The embossed markings 22 of the embossed insulating packaging 10 are shown in Figure 1 by means of thick, continuous transverse lines. The embossed insulating packaging 10 comprises at least one embossed marking 22, which can run transversely, longitudinally, or obliquely. The embossed marking 22 is located in the area of ​​the fiber mat 16. The embossed marking 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 area of ​​the embossed marking 22. Figures 2a and 2b show examples of an embossed insulating packaging 10 with one embossed marking 22a and two embossed markings 22b, respectively, each running transversely to the longitudinal extent of the embossed insulating packaging 10. It can be seen that the embossed markings 22, 22a, and 22b are clearly visible as indentations 24 on the wrapping material 12.

[0092] Figures 3a and 3b show a longitudinal section through the embossed insulating packaging 10 depicted in Fig. 2b in two different views with varying degrees of abstraction. The embossing of the fiber mat 16 creates an embossed area 26, which is compressed compared to an unembossed area 28; that is, at least one spatial extent of the fiber mat 16 is reduced by the embossing 22. Consequently, the embossed insulating packaging 10 has a first fiber mat thickness 30 in the unembossed area 28, which is greater than a second fiber mat thickness 32 in the embossed area 26. The areas 26 and 28 can be directly adjacent to each other or separated by a transition area in which the fiber mat thickness increases. The embossing 22 can serve as a defined fold line for the embossed insulating packaging 10. Figure 4 shows the embossed insulating packaging 10 with a...two embossings 22, 22a, 22b, wherein a bending of the embossed insulating packaging 10 takes place according to the embossing 22, 22a, 22b.

[0093] In the following, an embodiment of a system for the production of an insulating package, for example the insulating package 10, is explained with reference to Figures 5 to 8.

[0094] The system 34 for manufacturing the embossed insulating packaging 10 comprises an embossing tool 36, shown in Figure 5, which is slidably attached to the device frame 38 by means of a sliding device 37. The system 34 further comprises another 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, Figure 5 shows 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.

[0095] The system 34 further comprises a transport device 46, which in the illustrated embodiment includes several belts 48. The transport device 46 runs over at least one deflection pulley 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.

[0096] The embossing tool 36, 40 has at least one recess 54 into which a section of the transport device 46, in particular a section of the belt 48, engages. In the illustrated embodiment, the at least one recess 54 is provided in the first embossing unit 42. As can be seen in Figure 5, the section of the transport device 46 engages in the at least one recess 54 when the first embossing unit 42 is in its embossing position, i.e., when it is moving towards the second embossing unit 44, and / or when the section of the transport device 46 engages in the at least one recess 54. Although not apparent in the figures, the transport device 46 disengages from the first embossing unit 42 when the first embossing unit 42 is in the open position.In the view shown in Figure 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.

[0097] The following describes the embossing process in detail. First, an insulating package is positioned on the transport device 46 so that the transport device 46 holds the insulating package. The transport device 46 then positions the insulating package relative to the embossing tool 36, 40, i.e., the insulating package is located between the first embossing unit 42 and the second embossing unit 44. The embossing units 42 and 44 are then moved into the embossing position, i.e., they move towards each other. As the first embossing unit 42 moves into the embossing position, the transport device 46 engages in 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 package to be embossed. The section of the insulating package to be embossed is then released from the transport device 46.

[0098] A first movement device 56 is provided for moving the first embossing unit 42, and a second movement device 58 is provided for moving the second embossing unit 44; these are best illustrated in Figure 6. The first and second movement devices 56 and 58 each comprise a pressure cylinder for applying pressure to move the first and second embossing units 42 and 44 towards each other. In a specific embodiment, an embossing pressure of approximately 6 bar is applied. 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.

[0099] After the insulating packaging 10 has been embossed for a predetermined time and under a specific embossing pressure, the embossing tool 36, 40 is moved into the open position, and the embossed insulating packaging 10 is removed from the embossing tool 36, 40 by means of the transport device 46 and exits the system 34. The insulating packaging, or rather the embossed insulating packaging 10, is thus held by the transport device 46 during the embossing process. The at least one recess 54 in the embossing tool 36, 40 allows the embossing process to take place while the insulating packaging 10 is held by the transport device 46, thus providing exactly one transport device 46 for feeding, embossing, and transporting the insulating packaging 10.

[0100] Figure 7 shows an embossing station 59 comprising 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 opposing embossing elements 60. It is understood that there may be more or fewer recesses 54 or more or fewer embossing elements 60.

[0101] The first embossing unit 42, for example a first embossing die, has a V-shaped recess 62, as shown in Figure 8. An internal 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 Figure 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 internal angle α of 100°, and the legs of the V-shaped projection 64 of the second embossing unit 44 enclose an angle of 90°. One 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 of 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).

[0102] The process steps for manufacturing an embossed insulating package 10, for example, the embossed insulating package 10, are shown as a flowchart in Figure 9. In step S10, an insulating package is provided that includes at least one area to be embossed. The process further includes step S20, in which the insulating package is positioned relative to the embossing tool 36, 40. The transport device 46 can be used for this purpose. This is followed by 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 package by means of the embossing tool 36, 40 for a predetermined embossing time, so that the fiber mat 16 in the engagement area of ​​the embossing tool 36, 40 is compressed in step S40.In step S50, the embossing tool 36, 40 is moved into an open position, and in 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 step S70, in which the embossed insulating packaging 10 is folded such that the embossing 22, 22a, 22b defines the fold line.
