Technical Field

[0001] The utility model belongs to the technical field of composite flexible packaging films and composite flexible packaging bags, and in particular relates to an environmentally friendly composite flexible packaging film bag with special texture and touch. Background Art

[0002] Composite flexible packaging film is a flexible packaging material made by combining two or more different materials through a specific process. This packaging material can give full play to the advantages of each component material, and has the characteristics of strong protection function, light weight, softness, diverse shapes, good dimensional stability, etc. It is widely used in food, medicine and other fields.

[0003] As the market demand for packaging functions continues to increase, the functions of multi-layer composite films are becoming more comprehensive. In order to meet specific functional requirements, traditional composite flexible packaging films and flexible packaging bags use different composite process combinations to achieve high permeability resistance, anti-corrosion and other functions. The surface of composite flexible packaging films and flexible packaging bags is bright or matte, and the surface texture and touch experience are relatively simple, which is easy to leave fingerprints and oil stains, affecting the consumer experience.

[0004] Therefore, the above problems need to be solved urgently. Utility Model Content

The outer plastic film and the printed polyolefin film are bonded by a first adhesive layer. The printed ink layer printed on the printed polyolefin film and the barrier layer are bonded by a second adhesive layer. The barrier layer and the inner plastic film are bonded by a third adhesive layer. The surface of the outer plastic film away from the inner plastic film is provided with a texture. The utility model provides a barrier layer between the outer plastic film and the inner plastic film, thereby improving the barrier property of the composite flexible packaging film bag, meeting the barrier requirements of specific packaging for oxygen, water vapor, fragrance, light, etc., helping to prevent the invasion of microorganisms and reduce the risk of food spoilage. A printing ink layer is provided on the printed polyolefin film, and patterns can be printed as needed to improve the aesthetics of the composite flexible packaging film bag. The textured outer plastic film enhances the texture and touch of the composite flexible packaging film bag, improving the consumer experience.

[0007] Furthermore, in the above-mentioned environmentally friendly composite flexible packaging film bag with special texture and touch, the outer plastic film is made of transparent polyolefin. Transparent polyolefin has high transparency, is suitable for displaying the pattern of the printed ink layer, has low density, good wear resistance, toughness and tear resistance, strong corrosion resistance, good colorability, strong weather resistance, can be recycled and reused, and reduces environmental pollution.

[0008] Furthermore, in the above-mentioned environmentally friendly composite flexible packaging film bag with special texture and touch, the inner plastic film is made of polyolefin, which has low density, good wear resistance, toughness and tear resistance, strong corrosion resistance, good colorability, strong weather resistance, can be recycled and reused, and reduces environmental pollution.

[0009] Furthermore, in the above-mentioned environmentally friendly composite flexible packaging film bag with special texture and touch, the first adhesive layer, the second adhesive layer and the third adhesive layer are made of polyurethane adhesive.

[0010] Furthermore, in the above-mentioned environmentally friendly composite flexible packaging film bag with special texture and touch, the barrier layer adopts a co-extruded film of polyolefin and EVOH, or the barrier layer adopts a co-extruded film of polyolefin and PVC, or the barrier layer adopts a co-extruded film of polyolefin and PA. The co-extruded film of polyolefin and EVOH combines the excellent mechanical properties and processing properties of polyolefin with the excellent barrier properties of EVOH, and is suitable for product packaging with strict requirements on shelf life. The co-extruded film of polyolefin and PVC integrates the flexibility, heat sealing and tear resistance of polyolefin and the transparency and cost-effectiveness of PVC to provide an economical barrier material. The co-extruded film of polyolefin and PA significantly enhances the mechanical strength and puncture resistance of the composite flexible packaging film bag, has good gas barrier properties, and is suitable for high-end packaging fields with high strength, high barrier properties and good processing properties.

[0011] Furthermore, in the above-mentioned environmentally friendly composite flexible packaging film bag with special texture and touch, the barrier layer adopts a polyolefin coating film coated with PVA or PVDC, or the barrier layer adopts an aluminized polyolefin film. The polyolefin coating film coated with PVA or PVDC has excellent barrier properties and strong stability, which can meet the requirements for high barrier properties and the requirements for long shelf life and environmental protection of composite flexible packaging films. The aluminized polyolefin film can provide high barrier properties while giving the composite flexible packaging film bag a strong metallic texture.

[0012] Furthermore, in the above-mentioned environmentally friendly composite flexible packaging film bag with special texture and touch, in order to increase the aesthetics of the environmentally friendly composite flexible packaging film bag, the outer plastic film is provided with brushed horizontal stripes or brushed vertical stripes or large-grain coarse sand frosted textures. Different texture designs can add visual layers and textures to the composite flexible packaging film bag. The brushed treatment presents a delicate gloss or matte effect, while the large-grain coarse sand frosted texture gives the product a modern, low-key appearance that meets the aesthetic preferences of different users. Moreover, compared with the glossy or matte surface, different texture designs are not easy to detect even slight scratches, and are not easy to leave fingerprints and oil stains, which improves the practicality and durability of the composite flexible packaging film bag.
