Gas-barrier plastic packaging laminate Thin Gusset Full Description Background packaging laminate The present invention relates to a stress crack formation gas barrier having strength when a stress crack is formed between the layers of the laminate good integrity and perfect bending stiffness Alia as well as sealable polyolefin film comprising outer layers of Polyolefin 0 polymer laminated to a first polymeric carrier layer and a second layer SiO, first gas barrier layer of Gla coated to a second polymeric carrier layer; and a 55-laminate polymeric intermediate layer (SiO, gas-barrier) between the first and the second gas-barrier coated polymeric carriers. The invention also relates to a method for making a thin collector plate and for collecting vessels made of the laminate. packaging containers | 0 In the current market, there is an increasing need for collection containers for liquid food and beverages on Uda of the type that are available in single-use plastic bags; preferably at least; at a certain part of the collection container; transparent to show the contents to the consumer when displayed on the shelf for example in a food store. Collecting packages of this shall be provided with a paper tube, which is used for direct drinking, or with a pull spout, which is used more prior le ppt for opening and pouring the contents; these laminated packages do not have the advantage that In having a comparison with drinks collection packages made of grip stability after and stability when gripping the most common cardboard thin laminate sheets of the tetrabrick type (a more positive brand dn however; it has a striped shape Tetra Brik® (Registered) Y. ‎AKER

. in many countries; In addition, there is controversy over the fact that the amount of aggregate used in addition to the size of the vacuum collection vessel is small and that it can be recycled with other similar flexible plastics. Furthermore; Conventional Tetra Brik® (registered trademark) collection packaging includes an oxygen barrier layer 0 of aluminum foil which is considered less List SA in some countries and makes it impossible to use a packaging Transparent compilation. In the continuous, high-speed collection processes known for their use of cardboard collection packages of the type Tetra Brik® (registered trademark) (Tera Brik®), a network of thin aggregate sheets is continuously swayed in the form of a tube; filled with contents 0 and closed in the form of collection vessels on the Pillow shaped by ules heat sealing and simultaneous cutting cutting.Then the pillow shaped collecting vessel is usually chamfered making it into a parallelepiped.The main advantage of the principle of this continuous assembly process which ctube-forming includes ctube-forming filling and sealing in that it can 0e The grid is sterilized continuously just prior to the ctube-forming process, ensuring that an aseptic assembly process can occur i.e. a process where the content to be tke is cleared as well as The collected material itself is bacteria and the filled collection vessel is produced under such pure conditions that the filled collection container can be stored for a long time at ambient temperature as well without the risk of microorganisms growing in the product being filled. Important for long-term storage the gas barrier properties of the collection vessel being filled and sealed; Which in turn depends to a large extent on the gas barrier properties of the laminate itself as well as on the qualities of the sealing materials and the opening arrangement of the final assembly package. Another significant advantage of the Tetra Brik® (registered trademark) assembly process, as mentioned by el, is the possibility of a continuous, high-speed assembly process, which has a significant impact on cost-effectiveness. Beverage collection packages on Aa are usually made into Youll bags

¢ which are currently offered on the market by other non-sterile processes; More complex, expensive and less continuous. In the ALD technique Lad is known to apply gas barrier coatings of .5:0 over a substrate by the plasma enhanced chemical vapor deposition (PECVD) process | 0 or 9 The advantages of using a 0:5 gas barrier layer over other gas barrier materials are that it has a positive environmental profile and secondly that it is unaffected i.e. the barrier properties remain completely intact; when in contact with ambient moisture or ambient liquid; And it is transparent, and because it is placed in the form of thin layers (fas), it is also flexible and resistant to cracking when bent or eh-Ve. It is known from European Patent No. 654 7085 AD to laminate two gas-barrier layers of a compound of silicon (Jia silicon dioxide) Silicon dioxide so that one meets the other with an intermediate adhesive layer. is that; This document does not mention the resistance when crack formation under stress, the homogeneity of the thin film layer when subjected to mechanical stress and the toughness properties of the thin film, nor does it mention the existence of an intermediate layer that provides shock absorption Tals on the toughness of the thin film as well. Furthermore; The layers of silicon dioxide (0,5:0) are Tan different from the layers “Ai” laa by PECVD used according to the invention. Thus, there is a need for a thin collector plate; gas-tight; free Foils with properties suitable for use in a continuous and aseptic high-speed aggregation process© similar to Tetra Brick Aseptic (Registered Trademark) Brik Aseptic® 1608. Important factors for such a process are stiffness, elasticity, and elasticity. and homogeneity of the thin gusset. If the web of the thin gusset is flexible (faa) and easy to dislodge during the high-speed tube forming process, the process will not be able to continue safely and continuously. In terms of cs AY) if the thin gusset is vo Tan thick To obtain the necessary hardness and durability, it can be difficult to manage the

It is during the process of forming folds; And if it is not flexible, it has shock absorption properties during transportation and handling; It will be prone to cracking and lose its homogeneity as a result of mechanical stress. Moreover, naturally; The cost-effectiveness of the material itself will decrease as the thickness increases. Furthermore; Bundling packages formed by folding from a thin gusset plate should have a strength of 0 when stress cracking is formed to withstand being handled when transported etc.; Which is a basic requirement that is difficult to combine with the requirements for hardness. The bagged beverage collection packages available at the time often have a laminated structure that includes a single gas barrier layer of; For example; A polymer of ethylene vinyl alcohol (EVOH) ; The requirements regarding 1 hardness properties are not required according to the present invention. Therefore; @Judy The object of the present invention is to provide a thin composite sheet that mitigate the above disadvantages and problems. The object of the present invention is to provide a thin foil-free collage plate; It has gas-blocking properties suitable for aseptic assembly and long-term storage; 1 In addition to sufficient flexural strength, sufficient homogeneity and resistance to stress cracking under mechanical stress to be suitable for use in continuous, high-speed collection of liquid foods by continuous tube forming and for supplying collection packages with durability under repeated stress during transportation and handling. A further object of the invention is to provide a thin-film gusset plate membrane having a strength of 0 cavities of this kind but being Td , sufficient to form pleats from the gusset at at least one end of the gusset. Another object of the invention is to provide a film of a laminate having the aforementioned properties as well as a wad to give an assembly packaging made of a laminate an attractive appearance.

+ The AIS directs the invention towards a collection vessel which is filled with a gay liquid beverage or food from the GE foil collector plate of the invention as well as a method for making the laminated film aggregate according to the invention. General description of the invention ° The aforementioned objective is achieved by using an intermediate polymeric layer 2 laminated between the two carrier layers os tld ot sede with the first and second gas barrier layers. The polymeric intermediate layer comprises at least two first and second partial layers; where said first sublayer has a higher stiffness than that of said sublayer AB and said second sublayer has higher elastic properties than those of said first sublayer. The entire assembly structure includes the advantages of structural sandwich construction and a flexible shock absorber in addition to a stiffness enhancer to obtain a diaphragm that has good bending strength and maintains its homogeneity under aggressive transport conditions. The sandwich panels, which are represented in this statement, are in the two membranes consisting of two load-bearing layers (fad sl) in the form of Plas for two sill lips in the form of a letter 1 Cua beam, which are resistant to bending loads and increase From the strength when bending AS ll by spacing them from each other with an intermediate layer. is that; In contrast to the Cia-shaped sill structure, the low-density lacs Lay filler provides a continuity of lips or cheekbones. XY. It was noted that the permeability of the partial layer A, which forms the intermediate layer, increases the resistance of the collection package when a crack is formed during the cyclic loading process, i.e. subjected to repeated stresses or vibrations. Jill by absorbing mechanical stresses through reversible elastic deformations. .a

It was also noted that the stiffness property of the first partial layer constituting the intermediate layer provides an additional contribution; In addition to the interstitial effect; Increases the stiffness properties of the thin composite plate as a whole. Furthermore; It has been noted that; For comparison; If the intermediate 0 layer consists of a single layer of high hardness polymer; Jie the polymer constituent of the first prepared partial layer Gay of the present invention; There will be an increased risk of stress crack formation when subjected to mechanical stress conditions. cad is not tested Note that; For comparison; if the intermediate layer consists of a single layer of a polymer with high elastic properties; It may impair the stability of the thin sheet 0 Sealing Process AY Tok Polymers with high elastic properties have a tendency to melt greatly and escape from the sealing zone; That is, it narrows the closing hole. The thickness required for such an intermediate layer increases the costs of making the thin sheet in an undesirable way. To meet these problems in a satisfactory manner; Tests were carried out where the intermediate layer consisted of a blended mixture of a high-strength polymer and a polymer with the following high-elasticity properties (cual 10: 75/786 20/46 and 50/10). is that; Results show similar failure frequencies (with rates ranging from © to 14) during transfer test simulations; Sal considered lea cracking as in the case of a single-layer intermediate layer of polymer with Ale strength. Thus, the appropriate solution to the problem and the need mentioned above” is to supply a thin bulk plate with good gas-blocking properties by laminating the two films composed of two carrier layers of polymers;33 and coating them with two gas-barrier layers of (SiOx) in the form of a composition with a spacer medium layer Jedi first and second sublayers on (BY) where said first sublayer has higher stiffness than said second sublayer and said second sublayer has higher elastic properties than those of said sublayer

They can be closed fiom Ja the first mentioned; The thin sheet also includes two thermoplastic polymer layers consisting of a thermoplastic polymer and in the best embodiment; The middle layer consists of three partial layers; where the third partial layer is identical to the first or second partial layer and the three partial layers are arranged symmetrically in the middle layer; That is, so that the two identical partial layers are on each of the outer sides of the middle layer. The presence of a symmetrical arrangement of wrinkled inter alia (SiO) reduces the risk of cracking of another layer and ensures good sealing. Since it was also found that a larger amount of polymer with elastic properties is preferred high compared to a polymer with a high hardness; in the intermediate layer; the best morphological embodiment 0 of the intermediate layer is that the third partial layer is identical to the second partial layer and that they are arranged on each side of the first partial layer; where it is preferable All three layers have substantially the same thickness.

The structural interfacial structure of the two relatively rigid load-bearing layers laminated on either side of the polymeric intermediate layer comprises a thermoplastic 0 polymer with elastic properties that ensure that the thin sheet has good resistance to cracking under repeated mechanical-stress processes and, surprisingly, durability at Lad good bending is related to its thickness. In addition (lal) the arrangement of the two SiOx layers deposited with ely PECVD has been shown to result in a ctow-fold increased gas barrier compared to a thin sheet or membrane containing only one 01 08 layer Thus, the composition that includes a distancing intermediate layer that also acts as a “buffer Lass! permeable llll in particular to oxygen gas 28 provides improved gaseous holding properties, which proves a synergistic effect resulting from the use of the special structure. Thus the plate has The thin film has excellent gas trapping properties and is economical and easy to process during a continuous high-speed aggregate process.The total thickness of the intermediate layer ranges from 90 to 00 preferably from YO to 786 of the total thickness of the thin aggregate plate.The intermediate layer, formed on less than a first partial layer and a second partial layer; the thicker separate layer in the thin plate. The thickness of the two carrier layers preferably ranges from about © to about “Ye” and preferably “-” to range from about © to about 717 of the total thin aggregate plate thickness. The two load-bearing layers contribute to the overall bending strength of the thin composite plate not only through their thickness but also by their overlapping with the comparatively thicker spacer intermediate layer.

Alternative methods exist for depositing layers other than Yoo ranging from about 880 to about 1 on polymeric films; however, they It usually results in the production of organic SiOx Jie inorganic layer in cracks that are thicker and less flexible. This in turn, due to the formation of cracks in the SiOx layers, usually leads to the production of thin sheets that are of poorer quality in terms of oxygen-trapping properties ( SiOx layer of the invention that the two gas barrier layers of 8:0 are placed by Gy and thus oxygen is preferred from a plasma containing an organic silicon compound SiOx for PECVD by the method of hexadimethylsiloxane hexagonal SL Je corganic silicon compound (HDMSO) 030 dV om.
