Description

Technical Field

[0001] This invention relates to a machine for processing roll materials for producing multi-layer materials, especially multi-layer packaging materials, and particularly single-material sequentially connected roll materials.

[0002] Furthermore, the present invention relates to a method for producing multi-layer roll materials, particularly multi-layer packaging materials, and especially single-layer materials.

[0003] In addition, the present invention relates to a packaging material. Background Technology

[0004] Multilayer materials are used, for example, as packaging materials specifically for packaging food, pharmaceuticals, medical devices, optical components, and electronic components. In this application area, one of these layers is often a so-called barrier, protecting the packaged goods from ambient moisture and / or ambient air and / or other gases. Furthermore, it can also serve as an aroma barrier and / or a light barrier.

[0005] Known multilayer materials are made from multiple rolls of material that need to be attached to each other to form a multilayer. Therefore, the production of these materials involves manufacturing processes and machines specifically for producing individual rolls or components, as well as processes and machines specifically for producing combinations or components of rolls. Typically, the different layers of a multilayer material have different functions. For example, three layers may exist, one with a sealant function, one with a barrier function, and one for printing.

[0006] As businesses and consumers become increasingly concerned about the depletion of natural resources, so too does the drive towards a circular economy, in which recycling is an unavoidable reality. Recycling capabilities are becoming increasingly important, particularly for the packaging industry.

[0007] Achieving this is challenging for packaging manufacturers, especially when it becomes, for example, a multi-layered flexible barrier packaging. Typically, recycling such packaging requires separating various polymers and metal foils, which can be costly or impractical. Manufacturers face the challenge of simplifying their flexible barrier packaging. This often involves moving towards a single material constructed from similar or identical polymer grades that can be recycled as a single substance.

[0008] A single material is defined as primarily comprising one type of material, such as PE (LDPE, LLDPE, HDPE), PP, PET, paper, or biodegradable plastics. For plastics, this means more than 90% of a single polymer type. Lamination and bonding processes are known to be used to produce single materials. These processes involve other materials necessary besides the single material itself, and may fail to meet the threshold for being defined as a single material, especially if the material subsequently undergoes a printing process, for example. Summary of the Invention

[0009] The purpose of this invention is to simplify and increase the cost-effectiveness of producing multilayer materials. This is particularly applicable to the production of multilayer packaging materials, especially single-layer materials.

[0010] This problem is solved by a sequentially connected roll-to-roll material processing machine of the type described above, comprising a first vacuum coating unit for depositing a first coating material onto a substrate (e.g., film, paper, etc.) of the roll material to be processed, and an extrusion coating unit for pressing an extruded material film onto the roll material to be processed. The sequentially connected roll material and extruded material are made of essentially the same material. The extrusion coating unit is positioned behind the first vacuum coating unit relative to the processing direction. Further, the first vacuum coating unit and the extrusion coating unit are arranged in a vacuum chamber. Therefore, the sequentially connected roll-to-roll material processing machine is suitable for producing materials comprising at least three layers. Both the vacuum coating unit and the extrusion coating unit are arranged in a vacuum chamber, and not merely as pre- and post-processing in vacuum coating machines known in the prior art. If the multilayer material is a packaging material, the roll-to-roll material processing machine can also be referred to as a packaging structure production machine. Compared to prior art roll-to-roll material processing machines, the roll-to-roll material processing machine according to the present invention is capable of performing a combination of sequentially connected process steps (particularly metal coating and extrusion in separate machines that have been used until now). Therefore, the number of process steps associated with the processing and transport of intermediate materials is reduced. Specifically, intermediate roll material (i.e., roll material that has been processed by some but not all of the process steps) does not need to be wound on the reel before undergoing subsequent process steps. The same applies to unwinding the intermediate roll material to allow it to undergo subsequent process steps. Processes related to bonding or lamination are also no longer required. This saves production time and production costs.

[0011] Furthermore, because the absence of processing and transport steps significantly reduces the risk of contamination and / or mechanical damage, such as that caused by unwinding and rewinding steps for components of multilayer materials, multilayer materials produced by sequentially connected roll-to-roll material processing machines can have enhanced quality. Additionally, since the film of the first coating material can be fragile and / or very thin, the quality of the multilayer material is further enhanced by directly covering the film of the first coating material with an extruded material used as a protective layer. This is done before the material leaves the machine.

[0012] Furthermore, sequentially connected roll material processing machines are suitable for producing multilayer materials with simple structures, thus facilitating recycling. In this paper, multilayer materials primarily made of a single material can be produced; for example, 95% of the mass or volume of the multilayer material can be made of the same material to obtain a single material that provides enhanced recycling capabilities.

[0013] The roll material to be processed, i.e. the carrier material or substrate used for different coating materials, can be a polymer material, such as polyethylene or polypropylene, especially foil-based or biopolymer-based structures.

[0014] The roll material can be provided in the form of a ring roll or a discontinuous roll. If the roll material is provided in the form of a ring roll, the roll material processing machine can operate "from roll to roll", that is, the roll material to be processed is placed on the roll, and the processed multi-layer roll material is also wound on the roll.

[0015] Sequentially connected roll material processing machines can generally operate continuously. This does not preclude some units of the roll material processing machine from operating discontinuously or in batches. Roll material is placed on a spool, and changes to the spool can cause discontinuities in the process. The roll material to be processed can be continuously supplied for the entire spool, and finished multi-layered material can exit the roll material processing machine continuously. Different possibilities exist for changing the spool to ensure the continuity known in the prior art. Another possibility is to change the spool and thus introduce discontinuities in the process steps. The roll material processing machine may include one or more buffer units to make units operating discontinuously compatible with units operating continuously.

[0016] In this document, the barrier film of a material is understood as a thinner layer of material compared to the substrate or carrier material to which it is coated. Preferably, the thickness of the barrier film / layer is less than 90% of the thickness of the substrate, more preferably less than 99%.

[0017] Preferably, the membrane of the first coating material serves as a barrier to prevent moisture and / or gas from passing through the multilayer material.

[0018] The multilayer material leaving the roll material processing machine according to the invention is preferably prepared for packaging goods, such as food. Therefore, no further major processing, such as lamination, is required.

[0019] A sequentially connected roll-to-roll material processing machine may additionally include a second vacuum coating unit for depositing a film of a second coating material onto the roll material to be processed. The second vacuum coating unit is positioned relative to the processing direction between the first vacuum coating unit and the extrusion coating unit. Both the film of the first coating material and the film of the second coating material can act as barriers preventing moisture and / or gases from passing through the multilayer material. Moreover, the film of the second coating material is protected by the film of the extrusion material before leaving the roll-to-roll material processing machine. Therefore, the risk of contamination and / or mechanical damage to the film of the second coating material is also very low. Thus, the sequentially connected roll-to-roll material processing machine can produce high-quality multilayer materials.

[0020] Preferably, at least one of the first vacuum coating unit and the second vacuum coating unit is a vapor deposition unit. The vapor deposition unit can be a physical vapor deposition unit using liquid or solid coating materials or a chemical vapor deposition unit using chemical vapors. Sometimes, such a vapor deposition unit is also referred to as a metal sputtering device, even if the coating material is not necessarily a metal in the strict sense, but can be a partially oxidized metal. Such a vapor deposition unit is suitable for providing a film of coating material in a precise and efficient manner. The resulting coating is highly reliable.

[0021] A vapor deposition unit may include a chamber in which a wire coated with a material (e.g., aluminum) is fed to a separate resistance-heated intermetallic evaporator, causing the wire to melt and evaporate.

[0022] According to an embodiment, at least one of the first and second vacuum coating units includes a region for guiding the roll material. This can be, for example, a processing drum for supporting the roll material to be processed, wherein at least one of the processing drums is additionally associated with the extrusion coating unit and serves as a support for the roll material to which extrusion material is applied. Therefore, the processing drum is shared between at least one of the first and second vacuum coating units and the extrusion coating unit. If a second vacuum coating unit is used, the processing drum is preferably shared between the second vacuum coating unit and the extrusion coating unit. Therefore, extrusion coating is always the final step. The processing drum can be cooled. The shared drum allows for a compact design of the roll material processing machine.

[0023] Another possibility is, for example, guiding the roll material in a free-spanning manner without using a processing drum.

[0024] A free-span arrangement can be defined as a vacuum roll-to-roll coater in which the substrate to be vacuum-coated is held between support rollers with an evaporation source in an unsupported / free-span arrangement. The evaporated material is applied in an unsupported and uncooled manner by evaporation and condensation onto a polymer roll. The advantages of this method are reduced deposition below the wrinkles on the processing drum due to thermal deformation of the substrate on the cooled drum, and prevention of tramline defects in the metallized film. Free-span deposition also has some advantages based on improved nucleation and improved barrier properties of the film growth. The disadvantage of free-span is the reduced cooling effect due to the omission of the cooled processing drum.

[0025] In one variant, the roll material processing machine includes a printing unit for printing on the roll material to be processed. Therefore, multi-layer materials can have printed content. Consequently, it can be used directly for packaging purposes or other applications.

[0026] The printing unit can be positioned behind the extrusion coating unit relative to the processing direction and can be adapted to print on a film of the extruded material. Therefore, the print will be printed on the outer / surface of the multilayer material. This makes it easier, for example, to remove during recycling.

[0027] A sequentially connected roll-to-roll material processing machine may include a vacuum chamber, wherein at least one of a first vacuum coating unit, a second vacuum coating unit, an extrusion coating unit, and a printing unit is arranged inside the vacuum chamber. Preferably, all the aforementioned units are arranged inside the vacuum chamber. Herein, the vacuum chamber is particularly suitable for generating a technical vacuum, i.e., a volume with a reduced pressure compared to atmosphere. Therefore, multilayer materials are protected from atmospheric influences during their production process. Thus, the risk of contamination, such as from dust, is very low. Consequently, the roll-to-roll material processing machine is capable of producing high-quality multilayer materials.

[0028] Furthermore, the sequentially connected roll-to-roll material processing machine can be designed in a modular manner, allowing the second vacuum coating unit and printing unit to be easily arranged within the roll-to-roll material processing machine as needed and removed from it when not required. Therefore, the roll-to-roll material processing machine is suitable for producing a variety of multilayer materials used in a variety of applications.

[0029] This problem can also be solved using the methods described above, including the following steps:

[0030] a) Provide substrates in the form of continuous rolls or discrete rolls.

[0031] b) Depositing a film of a first coating material, particularly a film of a metal or metal oxide, on a substrate, and

[0032] c) Subsequently, a film of extruded material, particularly a polymer film, is pressed onto the film of the first coated material;

[0033] The substrate and the extruded material are made of essentially the same material, and steps a) to c) are carried out in a vacuum chamber.

[0034] d).

[0035] This method allows for the production of multilayer materials comprising only one substrate, which can be used, for example, in food packaging applications. This method is efficient in terms of production time and cost. The film of the first coating material can act as a barrier to prevent moisture and / or gases from passing through the multilayer material. The film of the first coating material is protected by the film of the extruded material. Therefore, the film of the first coating material can have high quality. It is exposed to only a very low risk of contamination and / or mechanical damage.

[0036] In one embodiment, a film of a second coating material, particularly a metal or metal oxide, is deposited on top of a film of a first coating material, and a film of an extruded material is pressed onto the film of the second coating material. The film of the second coating material can also serve as a barrier, complementing the function of the film of the first coating material. Therefore, multilayer materials can be equipped with different combinations of barriers depending on the desired application. Both barriers are protected by the film of the extruded material.

[0037] Ink can be printed onto a film of extruded material. Therefore, ink is applied to the outer surface of a multilayer material. For this purpose, ink application (i.e., printing) is relatively quick and easy. Furthermore, the ink can be removed mechanically or chemically during the recycling process. This makes multilayer materials easy to recycle.

[0038] The ink is preferably dried by ultraviolet light and / or electron beam. Such a drying process is simple to perform and allows for rapid drying. Furthermore, it can be applied under vacuum.

[0039] In a preferred alternative, the method is performed under vacuum. Again, vacuum should be understood as a technical vacuum defined by pressures below atmospheric pressure. Vacuum reduces the risk of contamination to all parts of the multilayer material.

[0040] It should be noted that all the effects and advantages mentioned regarding roll material processing machines generally also apply to methods for producing multi-layered materials, and vice versa.

[0041] This problem is further addressed by packaging materials, particularly for food packaging, especially single-material packaging materials comprising a single flexible substrate in the form of a continuous or discrete roll, a first coating material disposed on the substrate, particularly a film of a metal or metal oxide, and a film of extruded material disposed on top of the film of the first coating material. The substrate and the extruded material are essentially made of the same material, thus providing a single-material packaging material exhibiting enhanced recyclability. This packaging material has a relatively simple structure. Simultaneously, it is able to provide functionality comparable to known packaging materials comprising more than one substrate. This is especially true if the film of the first coating material acts as a barrier to prevent moisture and / or gas from passing through the packaging material. The film of the extruded material can have a protective function, particularly for the film of the first coating material. Therefore, the packaging material is robust. The simple structure allows for efficient production of the packaging material in terms of production time, necessary production equipment, and production costs. Furthermore, the simple structure allows for rapid and easy recycling of the packaging material.

[0042] In a preferred embodiment, a film of a second coating material, particularly a metal or metal oxide (e.g., aluminum or alumina), is disposed between the film of the first coating material and the film of the extruded material. The film of the second coating material may also have a barrier function that complements the function of the film of the first coating material. The combined barrier can provide a high level of impermeability relative to moisture and gases.

[0043] The substrate and extruded material can be made from the same material, particularly polypropylene or polyethylene, biopolymers, or biodegradable plastics. This further simplifies the structure of the packaging material and the processes used to produce it. Furthermore, recycling capacity is enhanced. This is especially true if the film of the substrate and extruded material constitutes the largest portion of the packaging material, for example, more than 90% by weight or volume, preferably more than 95% by weight or volume. In this case, the packaging material can be considered a so-called single material during recycling.

[0044] An ink layer can also be applied to the top of the film on the extruded material. Therefore, the packaging material can have an attractive appearance. Since the ink is applied to the outer surface of the packaging material, it is easy to apply the ink via a printing process. Furthermore, since the ink on the outer surface can be removed mechanically or by chemical etching, recycling is facilitated.

[0045] Preferably, the packaging material according to the invention is produced by using the method according to the invention on a roll material processing machine that does not use adhesives or lamination and / or sequentially connects according to the invention.

[0046] It should also be noted that all the effects and benefits mentioned regarding sequentially connected roll material processing machines and / or methods for producing multi-layer roll materials generally also apply to packaging materials, and vice versa. Attached Figure Description

[0047] The invention will now be described with reference to the accompanying drawings. In the drawings,

[0048] Figure 1 schematically illustrates a roll material processing machine according to the invention, which is adapted to perform the method according to the invention and is adapted to use a processing drum ( Figure 1a ) and use of free span arrangement ( Figure 1b To produce packaging materials according to the present invention.

[0049] - Figure 2 A cross-section of the packaging material according to the invention, produced on the machine of FIG1 using the method according to the invention, is shown.

[0050] - Figure 3 A roll material processing machine according to another embodiment of the invention is schematically shown, which is adapted to perform the method according to the invention and produce packaging materials according to the invention. Detailed Implementation

[0051] Figure 1a and Figure 1b A roll material processing machine 10 for producing multilayer material 12 is shown. In the illustrated embodiment, multilayer material 12 is packaging material 13 for packaging food.

[0052] The roll material processing machine 10 includes an unwinding machine 14 for supplying roll material 16 to be processed in the form of annular rolls.

[0053] The roll material 16 is flexible.

[0054] In addition, the roll material processing machine 10 has a rewinding machine 18 for winding the multi-layer material 12 produced, i.e., packaging material 13.

[0055] In the processing direction 20, the first processing drum 22 and the second processing drum 24 are inserted between the unwinding machine 14 and the rewinding machine 18.

[0056] In addition, first, second and third auxiliary drums 26a, 26b and 26c are provided to facilitate the continuous supply of roll material 16 through roll material processing machine 10.

[0057] It should be noted that the roll material 16 is processed in the roll material processing machine 10 in cooperation with multiple drums, but it is unwound from the drum (i.e., unwinder 14) only once, and is wound onto the drum (i.e., rewinder 18) only once during its entire processing.

[0058] according to Figure 1a and 1b The material processing machine 10 of the preferred embodiment shown includes a vacuum separator 27 that provides two vacuum states 29 and 31.

[0059] according to Figure 1a The first vacuum coating unit 28 is arranged adjacent to the first processing drum 22. It is adapted to deposit a film of the first coating material on the roll material 16.

[0060] The first vacuum coating unit 28 uses the first processing drum 22 as a support for the roll material 16.

[0061] Furthermore, the second vacuum coating unit 30 is disposed adjacent to the second processing drum 24. The second vacuum coating unit 30 is adapted to deposit a film of the second coating material on the roll material 16.

[0062] It uses a second processing drum 24 as a support for the roll material 16.

[0063] Both the first vacuum coating unit 28 and the second vacuum coating unit 30 are vapor phase deposition units.

[0064] In addition, an extrusion coating unit 32 is provided, which is adapted to press a film of extruded material onto the roll material 16.

[0065] The extrusion coating unit 32 is associated with the second processing drum 24.

[0066] This means that the extrusion coating unit 32 uses the second processing drum 24 as a support for the roll material 16 to which the extrusion material is coated.

[0067] In addition, the roll material processing machine 10 includes a printing unit 34 suitable for printing ink on roll material 16.

[0068] The above units are arranged in the following order along the processing direction 20: first vacuum coating unit 28, second vacuum coating unit 30, extrusion coating unit 32, and printing unit 34.

[0069] The roll material processing machine 10 also includes a vacuum chamber 36.

[0070] All of the above-mentioned units, namely the first vacuum coating unit 28, the second vacuum coating unit 30, the extrusion coating unit 32, and the printing unit 34, are arranged in the vacuum chamber 36.

[0071] Processing drums 22 and 24, auxiliary drums 26a, 26b and 26c, unwinding machine 14 and rewinding machine 18 are also located in vacuum chamber 36.

[0072] according to Figure 1a The vacuum chamber 36 of the preferred embodiment shown includes a vacuum separator 27 that provides two vacuum states 29, 31. The first vacuum state is constructed around the vacuum coating units 28, 30 and provides a higher vacuum, while the second vacuum state 31 is provided for the remaining units, thereby providing a lower vacuum and a higher pressure.

[0073] Figure 1b The diagram shows a processing machine 10 according to another embodiment of the present invention. During vacuum coating using a vacuum coating unit, the roll material is in a free-spanning arrangement, rather than being guided by processing drums 22, 24.

[0074] This arrangement corresponds to... Figure 1a The arrangement differs in that the roll material is laid across two rollers 23a and 23b or 25a and 25b, respectively, instead of using a processing drum that passes the roll material through a first vacuum coating unit 28 and a second vacuum coating unit 30. The two rollers 23a and 23b or 25a and 25b each lay across the roll material while the roll material undergoes a vacuum deposition step in vacuum coating units 28 and / or 30.

[0075] Both the first vacuum coating unit 28 and the second vacuum coating unit 30 are vapor phase deposition units.

[0076] Although described as using a processing drum or a free-span arrangement, it is clear that the processing machine according to the invention may also include a combination, meaning at least one vapor deposition coating unit having a processing drum and at least one vapor deposition coating unit having a free-span arrangement.

[0077] During the operation of the roll material processing machine 10, multi-layer material 12 is produced as follows.

[0078] First, the substrate 38 is configured as the roll material 16 to be processed. In the illustrated embodiment, the substrate 38 is a polypropylene foil (see [link to example]). Figure 2 ).

[0079] Then, the first coating material 40 film is deposited on the substrate 38 by the first vacuum coating unit 28.

[0080] The first coating material 40 acts as a barrier to prevent moisture and gas from penetrating the multilayer material 12.

[0081] In the illustrated embodiment, the first coating material 40 is aluminum oxide.

[0082] Subsequently, the second coating material 42 film is deposited on the first coating material 40 film by the second vacuum coating unit 30.

[0083] In addition, the membrane of the second coating material 42 serves as a barrier to prevent moisture and gas from penetrating the multilayer material 12.

[0084] In this embodiment, the second coating material 42 is silicon oxide.

[0085] Since the first coating material 40 and the second coating material 42 are different from each other, their respective material properties regarding impermeability to moisture and / or gas are at least partially complementary to each other.

[0086] Subsequently, the film of the extruded material 44 is coated onto the top of the second coating material 42 by the extrusion coating unit 32.

[0087] The film of the extruded material 44 is a protective layer that protects the film of the first coating material 40 and the film of the second coating material 42 from environmental effects such as chemical or mechanical stress.

[0088] In the illustrated embodiment, the extruded material 44 is polypropylene, and is therefore the same material as the substrate 38.

[0089] Subsequently, ink 46 is printed onto the top of the extruded material 44 via printing unit 34.

[0090] Ink 46 is dried within printing unit 34 by an electron beam.

[0091] As mentioned earlier, all of the above production steps are performed under vacuum within vacuum chamber 36.

[0092] Therefore, the resulting packaging material 13 includes a first layer formed from a single flexible substrate 38.

[0093] A layer of the first coating material 40 is applied on top of the substrate.

[0094] The film of the second coating material 42 is positioned on top of the layer of the first coating material 40.

[0095] It is covered by a membrane of extruded material 44.

[0096] The ink 46 layer is disposed on top of the film of the extruded material 44.

[0097] Therefore, the packaging material 13 comprises a total of five layers, of which the ink layer 46 is used only for optical purposes.

[0098] The arrangement of modules can be changed depending on the structure to be produced. Therefore, Figure 3 Another possibility for the processing machine is shown, in which the roll is unwound from the unwinder 14, passes through the extrusion coating machine, then through the first vacuum coating unit 28, then through the second vacuum coating unit 30, and then through the extrusion top coating unit 32 before being rewound by the rewinder 18.

[0099] Different modules can be joined together as needed for use in a vacuum condition or for all suitable vacuum conditions. This also provides flexibility.

[0100] Since different layers have different dynamic rates, the processing machine 10 according to the preferred embodiment can adapt to this fact by providing different drum sizes to compensate for the different deposition rates. The same method can be used to optimize the layer thickness.
