[0002] Apple cider vinegar is a beverage made by fermenting apple juice and then diluting it with other ingredients such as apple juice. It is not a kitchen condiment. The combination of apple cider vinegar and apple juice creates a sweet and sour flavor that balances the raw vinegar taste while adding the sweet aroma of fruit juice, making it very refreshing.

[0003] Traditionally, apple cider vinegar was packaged in glass bottles, plastic bottles, and cans, which were inconvenient to carry. With the rapid development of the beverage industry, the performance requirements for apple cider vinegar packaging materials have become increasingly stringent. These beverages not only need convenient packaging but also excellent sealing and freshness preservation, while maintaining their taste and nutritional value. Furthermore, the increased volume of goods transported due to improved transportation has placed extremely high demands on the mechanical strength of packaging materials. Innovation and upgrading of beverage packaging materials are key to the industry's development, meeting market demand for high-quality beverage products. Therefore, developing packaging materials with improved mechanical strength through multi-layer composite film structures has become a focus of industry research. Utility Model Content

[0004] Therefore, this utility model provides a composite material for apple cider vinegar strip packaging to overcome the problem of low mechanical strength of existing packaging composite materials.

[0005] To achieve the above objectives, this utility model provides a composite material for apple cider vinegar strip packaging, comprising:

[0006] It has a four-layer composite film structure arranged from the outside to the inside, wherein the first layer is the printing layer, the second layer is the barrier layer, the third layer is the reinforcing layer, and the fourth layer is the heat-sealing layer; the layers are connected by adhesive.

[0007] The printing substrate is made of biaxially oriented polyester.

[0008] The barrier layer is made of aluminum foil;

[0009] The reinforcing layer is made of biaxially oriented polyester or biaxially oriented polyamide.

[0010] The heat-sealing layer is made of cast polypropylene or polyethylene.

[0011] Furthermore, the outer surface of the printing layer is coated with matte varnish.

[0012] Furthermore, the thickness of the printing layer is 12.0 μm-20.0 μm.

[0013] Furthermore, the thickness of the barrier layer is 7.0 μm-12.0 μm.

[0014] Furthermore, the thickness of the reinforcing layer is 12.0 μm-20.0 μm.

[0015] Furthermore, the thickness of the heat-sealing layer is 60.0 μm.

[0016] Furthermore, the adhesive is a polyurethane adhesive.

[0017] Furthermore, the thickness of the adhesive is 1.5μm-2.0μm.

[0018] Furthermore, the ink is printed on the side of the substrate near the barrier layer.

[0019] Furthermore, the outer surface of the four-layer composite membrane structure is coated with matte varnish.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: by adopting a four-layer composite film structure design, this utility model significantly improves the overall strength and durability of the packaging material, and can effectively resist external impacts during transportation.

[0021] Furthermore, applying matte varnish to the outer surface of the printing layer can give the packaging a matte finish, reduce light reflection, make the packaging look softer and more upscale, enhance the overall texture and visual effect of the product, and meet consumers' aesthetic needs for product appearance.

[0022] Furthermore, the thickness of the substrate layer ensures printing quality while also considering material cost and processing performance. The barrier layer thickness, while meeting barrier requirements, minimizes material cost and packaging weight. The reinforcing layer significantly improves the material's tear resistance. The heat-sealable layer thickness ensures the reliability and stability of heat sealing, while also contributing to improved packaging impact resistance.

[0023] Furthermore, polyurethane adhesive, acting as the bonding agent between layers, possesses excellent bonding properties and chemical resistance, firmly bonding each layer of material together to form a unified whole. This effectively prevents delamination between layers, ensuring the stability and reliability of the packaging. The adhesive thickness ensures effective bonding while minimizing adhesive usage, reducing costs, and also avoiding negative impacts on the packaging's flexibility and processing performance due to excessive adhesive thickness.

[0024] Furthermore, ink design can visually reflect the product's appearance and specifications. Attached Figure Description

[0031] This utility model discloses a composite material for apple cider vinegar strip packaging, which solves the problem of low mechanical strength of packaging composite materials.

[0032] Please see Figure 1 A schematic diagram of the overall structure of a composite material for apple cider vinegar strip packaging;

[0033] One embodiment of this utility model provides a composite material for apple cider vinegar strip packaging, comprising:

[0034] It has a four-layer composite film structure arranged from the outside to the inside, wherein the first layer is the printing layer 1, the second layer is the barrier layer 2, the third layer is the reinforcing layer 3, and the fourth layer is the heat-sealing layer 4; the layers are connected by adhesive.

[0035] The material of the printing substrate 1 is biaxially oriented polyester;

[0036] The barrier layer 2 is made of aluminum foil;

[0037] The reinforcing layer is made of biaxially oriented polyester or biaxially oriented polyamide.

[0038] The heat-sealing layer is made of cast polypropylene or polyethylene.

[0039] Specifically, the outer surface of the printing substrate 1 is coated with matte varnish, which can prevent the printed pattern from being damaged by external friction and other factors, further extending the service life of the packaging. At the same time, the presence of matte varnish also helps to improve the contact performance between the printing substrate 1 and the external environment, such as providing a certain anti-slip effect, reducing the occurrence of packaging slippage due to an overly smooth surface during actual handling and sales.

[0040] Specifically, the printing layer 1 is made of biaxially oriented polyester film, which has good printability and surface gloss, and can clearly display product information. The barrier layer 2 is made of aluminum foil, which can effectively block the influence of external factors such as oxygen and water vapor on the contents, extending the product's shelf life. The reinforcing layer 3 is also made of biaxially oriented polyester, and the biaxial stretching process significantly improves the material's tensile strength and tear resistance. The heat-sealing layer 4 is made of cast polypropylene, which has excellent heat-sealing performance and mechanical strength, ensuring the reliability of the packaging seal.

[0041] Specifically, the thickness of the printing layer 1 is 12.0μm-20.0μm. The thickness of the printing layer ensures printing quality while also taking into account material cost and processing performance.

[0042] Specifically, the thickness of the barrier layer 2 is 7.0μm-12.0μm. The thickness of the barrier layer meets the barrier requirements while minimizing material costs and packaging weight.

[0043] Specifically, the thickness of the reinforcing layer 3 is 12.0μm-20.0μm, and the reinforcing layer improves the tear resistance of the material.

[0044] Specifically, the heat-sealing layer 4 has a thickness of 60.0 μm. The thickness of the heat-sealing layer ensures the reliability and stability of the heat sealing, and also helps to improve the impact resistance of the packaging.

[0045] Specifically, packaging composite materials achieve excellent mechanical and barrier properties by optimizing the thickness ratio of each layer.

[0046] Specifically, the adhesive is a polyurethane adhesive.

[0047] Specifically, the adhesive has a thickness of 1.5 μm to 2.0 μm.

[0048] Specifically, polyurethane adhesive is used to bond the layers together, and the thickness of the adhesive layer is controlled within the range of 1.5μm-2.0μm, which ensures the interlayer bonding strength while avoiding the increased cost caused by excessively thick adhesive layers.

[0049] Specifically, the ink is printed on the side of the substrate 1 near the barrier layer 2.

[0050] Specifically, the outer surface of the four-layer composite membrane structure is coated with matte varnish.

[0051] Specifically, when a matte finish is required for the composite film, a matte varnish can be applied to the outer layer. For a partial matte finish, a stencil-printed matte varnish can be used. This prevents the printed pattern from being damaged by external friction and other factors, further extending the packaging's lifespan. Simultaneously, the presence of matte varnish also helps improve the contact performance between the printed layer and the external environment, such as providing a certain degree of anti-slip effect, reducing the likelihood of packaging slipping due to an overly smooth surface during actual handling and sales.

[0052] For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
