Description

Technical Field

[0001] The utility model relates to the technical field of plastic films, in particular to an easily-tearable PE film. Background Art

[0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins are used for packaging and as coating layers. Plastic packaging and plastic packaging products occupy an increasingly larger share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives;

[0003] However, the existing PE film for packaging has triangular openings on both sides of the PE film, which makes it easy for people to tear the PE film, but the triangular openings penetrate the PE film, and the PE film has low connection strength. During the packaging process, when the PE film is subjected to too much force, the PE film is easy to break along the triangular openings, causing the previously packaged PE film to fail and causing a waste of resources. For example, patent No. CN202122314729.4 discloses a high-strength composite PE plastic film, in which the PE plastic film has triangular openings on both sides, which makes it easy for people to tear the PE film, and the triangular openings penetrate the PE film. There is no protection at the triangular openings, and the PE film has low connection strength, and the PE film is easy to break along the triangular openings. Utility Model Content

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present utility model, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "sleeved / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0020] In addition, in the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0021] Figure 1 The utility model shows an easy-to-tear PE film, comprising a PE film body 1, wherein the PE film body 1 comprises a high temperature resistant layer 14, a substrate layer 12, a tensile layer 13, and an isolation layer 11, a plurality of triangular openings 2 are arranged at equal distances on both sides of the PE film body 1, a plurality of tear holes 3 are arranged between two triangular openings 2 on the same vertical section, a connecting strip 4 is arranged between the triangular openings 2, the tensile layer 13 and the high temperature resistant layer 14 are arranged below the substrate layer 12, and the isolation layer 11 is arranged above the substrate layer 12;

[0022] The thickness of the connecting strip 4 is smaller than the thickness of the triangular opening 2 .

[0023] Working principle:

[0024] The utility model makes it easy for people to tear the PE film from the triangular opening 2 through the design of the triangular opening 2 and the tear hole 3. At the same time, the connecting strip 4 arranged at the triangular opening 2 ensures that the PE film is not easily disconnected from the triangular opening 2 during use, thereby maintaining the structural stability of the PE film and increasing the practicality of the PE film.

[0025] In the above solution, a bubble film layer 5 is provided above the isolation layer 11. With this technical method, a bubble film layer 5 is provided above the isolation layer 11, which can achieve a certain buffering effect. Such a design helps the PE film to absorb external impact or pressure when packaging food, provides additional protection performance, and increases the durability of the PE film.

[0026] In the above solution, the tear holes 3 are configured as holes of two different sizes, and the tear holes 3 of two different sizes are arranged between the two triangular openings 2. With this technical method, the tear holes 3 of two different sizes are arranged between the two triangular openings 2, which can not only meet the requirements of tearing the PE film along the multiple tear holes 3, but also ensure the strength of the PE film when it is subjected to tension.

[0027] In the above solution, the surface of the bubble film layer 5 is provided with an aerogel coating 51. With this technical method, the aerogel coating 51 has the characteristics of being lightweight and highly porous, and can provide better insulation performance while reducing the overall weight of the PE film.

[0028] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
