Description

Technical Field

[0001] The utility model relates to the technical field of packaging films, in particular to a high-barrier packaging film. Background Art

[0002] Packaging film is a thin material used to protect and encapsulate products, typically made of plastic, paper, or a composite material. This material can be customized to meet specific performance requirements, such as barrier properties, strength, transparency, and recyclability, depending on the application and needs. Packaging film can be categorized into various types, including but not limited to: Stretch film is primarily used to wrap goods, providing mechanical strength and protection. High-barrier film is used to package food items susceptible to environmental influences, such as fresh produce or soft drinks, to control the permeation of moisture, oxygen, odors, and flavors. Laminated film, produced by coextruding multiple layers of different resins, is suitable for packaging requiring specialized properties, such as tear and impact resistance. Shrink film, which shrinks to a tightly wrapped shape when heated, is commonly used for heat-shrink packaging. Retort film is used for specialized, high-temperature retort packaging, requiring heat and chemical resistance. Degradable or biodegradable films are environmentally friendly and can reduce long-term environmental damage. Packaging film has a wide range of applications, from food and beverage packaging to product packaging in the medical and electronics industries. With increasing environmental awareness, biodegradable films are becoming increasingly popular. Overall, packaging film is an indispensable component of the modern packaging industry.

[0003] Existing packaging films are mostly made of a single material, which may not effectively block gas and moisture. Furthermore, films made of a single material are relatively thin, resulting in reduced barrier properties and poor tensile strength. They are prone to tearing during use and have a short service life. Therefore, those skilled in the art have provided a high-barrier packaging film to address the issues raised in the background art.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1 、 Figure 2 , an embodiment provided by the utility model:

[0023] A high-barrier packaging film comprises a film body 1 and a reel 2. The film body 1 is wound around the reel 2, and a plurality of easy-tear holes 3 are provided on the surface of the film body 1.

[0024] Specifically, the film body 1 is rolled up around the reel 2 to facilitate storage of the film body 1, and a plurality of easy-tear holes 3 are provided on the surface of the film to facilitate tearing the film for use, thereby improving efficiency. The easy-tear holes 3 are provided in groups of 50 cm on the surface of the film body 1, and the spacing distance between the easy-tear holes 3 can also be changed during the production process. When in use, the film body 1 is spread out from the reel 2 according to the size of the packaging object and the film of appropriate size is torn off through the easy-tear holes 3.

[0025] Reference Figure 3 、 Figure 4The film body 1 includes a first barrier layer 101 and a second barrier layer 102. An adhesive layer 108 is fixedly provided on opposite sides of the first barrier layer 101 and the second barrier layer 102. A reinforcing mesh 103 is fixedly provided between the two adhesive layers 108. A high-temperature resistant layer 104 is fixedly provided on the upper end of the first barrier layer 101, an antistatic layer 105 is fixedly provided on the upper end of the high-temperature resistant layer 104, a wear-resistant layer 106 is fixedly provided on the upper end of the antistatic layer 105, and a heat-sealing layer 107 is fixedly provided on the lower end of the second barrier layer 102. The first barrier layer 101 is set as aluminum foil, the second barrier layer 102 is set as polypropylene material, the high-temperature resistant layer 104 is set as a polytetrafluoroethylene coating, the antistatic layer 105 is set as a fluorocarbon coating, the wear-resistant layer 106 is set as a ceramic coating, and the reinforcing mesh 103 is set as nylon material;

[0026] Specifically, by setting the first barrier layer 101 and the second barrier layer 102, the barrier property of the film can be improved. A reinforcing mesh 103 is provided between the first barrier layer 101 and the second barrier layer 102 to improve the overall tensile strength of the film body 1 and to increase its service life. During the manufacturing process, the reinforcing mesh 103 can be provided in multiple groups, and each group has a certain interval inside the film body 1 to facilitate the provision of the easy-tear line hole 3; the first barrier layer 101 is made of aluminum foil with excellent gas and water vapor barrier properties and good lightproof properties, and the second barrier layer 102 is made of polypropylene material with strong heat resistance and strong chemical corrosion resistance. The composite composition of the two can improve the high barrier property of the film while improving other advantages of the film; by providing a high temperature resistant layer 104, the stability and performance of the film in a high temperature environment can be improved. The high temperature resistant layer 10 4. The polytetrafluoroethylene coating has good high temperature resistance, can withstand up to 260°C, has good chemical stability and a smooth surface; by setting the antistatic layer 105, static electricity accumulation can be reduced to prevent dust and impurities from easily adhering to the surface of the film. The antistatic layer 105 is set as a fluorocarbon coating, which has excellent corrosion resistance and antistatic properties; by setting the wear-resistant layer 106, the wear resistance and service life of the film can be improved.

When packaging objects with packaging film, the edges can be heated so that the films are bonded together to seal the items, which is more convenient to use and efficient.

[0027] Working principle: When the film is used, the film is separated through the tear line hole 3, and then the object is wrapped. When wrapping certain objects, the film body 1 can be folded in half and the edges are heated to melt the heat-sealing layer 107 and stick together to form a packaging bag to hold the object;

[0028] Secondly, by arranging a first barrier layer 101 and a second barrier layer 102 in the film body 1 and arranging a reinforcing mesh 103 therebetween, the barrier performance of the film can be improved while the overall tensile strength of the film body 1 can be improved, and the service life can be improved. A high-temperature resistant layer 104 is arranged on the upper side of the first barrier layer 101, which can improve the stability and performance of the film in a high-temperature environment. By arranging an antistatic layer 105, dust and impurities can be prevented from easily adhering to the surface of the film. By arranging a wear-resistant layer 106, the wear resistance and service life of the film can be improved.
