[0027] Reference Figure 1-2 , an embodiment provided by the utility model:

[0028] An easy-tear packaging film includes a film body 1, the film body 1 includes a wear-resistant layer 101, a heat-insulating layer 102, a sealing layer 103, and a tough layer 104. The lower end of the wear-resistant layer 101 is fixedly arranged on the upper end of the heat-insulating layer 102, the lower end of the heat-insulating layer 102 is fixedly arranged on the upper end of the sealing layer 103, and the lower end of the sealing layer 103 is fixedly arranged on the upper end of the tough layer 104. The wear-resistant layer 101 is made of polyamide, the heat-insulating layer 102 is made of polyurethane, the sealing layer 103 is made of metallocene polyethylene, and the tough layer 104 is made of linear low-density polyethylene.

[0029] Specifically, the film body 1 is composed of a variety of different materials, among which the outermost wear-resistant layer 101 is made of polyamide material, which has good wear resistance and scratch resistance, and can effectively protect the packaging surface from external friction damage. The heat insulation layer 102 is made of polyurethane material, which has excellent heat insulation performance and can effectively reduce the impact of the temperature difference between the inside and outside on the items in the package. The sealing layer 103 is made of metallocene polyethylene material, which has excellent sealing and puncture resistance, can maintain good heat sealing strength, and improve the airtightness of the package. The toughness layer 104 is made of linear low-density polyethylene material, which provides good toughness to the film and prevents accidental breakage of the film during the tearing process. The film body 1 is designed with a multi-layer composite structure, and the characteristics of each layer of material complement each other to form a packaging material with excellent comprehensive performance. Through the reasonable combination of each layer of material, not only the wear resistance, heat insulation, sealing and toughness of the film are improved, but also the packaging is made stable in a variety of environments.

[0030] Reference Figure 1-5 , an easy-tear mechanism 2 is provided at the upper end of the film body 1, and the easy-tear mechanism 2 includes a fixed groove 201, a first adhesive layer 202, a tear strip 203, a second adhesive layer 204, a limiting piece 205, two sealing strips 206, a serration 207 and a reinforcing rib 208. The outside of the fixed groove 201 is opened at the upper end of the film body 1, one side of the tear strip 203 is fixedly arranged on one side of the inside of the fixed groove 201, the upper end of the first adhesive layer 202 is fixedly arranged on one side of the lower end of the tear strip 203, the lower end of the first adhesive layer 202 is pasted on the lower end of the inside of the fixed groove 201, and the second adhesive layer 204 is fixedly arranged on the lower end of the inside of the fixed groove 201. The upper end of the layer 204 is fixedly arranged at the lower end of the limiting piece 205, the lower end of the second adhesive layer 204 is pasted and arranged on one side of the upper end of the tear strip 203 and the lower end of the inner part of the fixing groove 201, one side of the limiting piece 205 is fixedly arranged on one side of the tear strip 203, the upper ends of the two sealing strips 206 are fixedly arranged at the lower end of the tear strip 203, the lower ends of the two sealing strips 206 are pasted and arranged at the lower end of the inner part of the fixing groove 201, the outer part of the serration 207 is fixedly arranged between the outer lower end of the tear strip 203 and the inner part of the film body 1, and the reinforcing rib 208 is fixedly arranged on the inner part of the tear strip 203;

[0031] Specifically, when the package needs to be opened, it is only necessary to gently pull the limiting piece 205 on the fixing groove 201, so that the second adhesive layer 204 at its lower end gradually separates from the fixation of the tear strip 203. When the second adhesive layer 204 is attached to the upper end of the tear strip 203, it can prevent the tear strip 203 from automatically tearing the package when the package is moved. As the limiting piece 205 moves to the preset position, the second adhesive layer 204 will complete the release of the limit on the tear strip 203. At this time, the limiting strip is pulled in the opposite direction to drive the tear strip 203 that has been released to move. The movement of the tear strip 203 will synchronously cause the first adhesive layer 202 below it to gradually separate from the film body 1. At the same time, the two close bonds at the lower end of the tear strip 203 The sealing strip 206 moves accordingly, gradually releasing the seal on the film body 1. When the tear strip 203 moves to the specified position, the serrations 207 on its outside will reduce the force required for tearing, providing the operator with an easy tearing experience, and the serrations 207 can be used to guide the tearing direction. At the same time, the reinforcing ribs 208 are fixed inside the tear strip 203, effectively enhancing the strength and stability of the tear strip 203, preventing the tear strip 203 from breaking during the tearing process, and allowing the operator to easily open the package with minimal effort and in the shortest time without the aid of any tools, thus completely saying goodbye to the trouble of laborious tearing and providing consumers with a more convenient and satisfactory user experience.

[0032] Working principle: The film integrates multiple materials into one. The wear-resistant layer 101 is located on the outermost layer and is made of polyamide. It has good wear resistance and scratch resistance and can effectively protect the internal structure from external physical damage. The heat-insulating layer 102 is adjacent to the wear-resistant layer 101 and is made of polyurethane. It has excellent heat-insulating properties and can effectively block external heat transfer and keep the temperature of the items in the package stable. The sealing layer 103 is located below the heat-insulating layer 102 and is made of metallocene polyethylene. It provides an excellent sealing effect and prevents moisture, air and other external factors from affecting the items in the package. The toughness layer 104 is the innermost layer and is made of linear low-density polyethylene. It gives the entire film good flexibility and tear resistance, making the package not easily damaged when subjected to impact and pressure, thus meeting various demanding packaging requirements.

[0033] Secondly, when the package needs to be opened, the operator only needs to pull the limiting piece 205 on the fixing groove 201 so that the second adhesive layer at its lower end gradually releases the limit on the tear strip 203. When the limiting piece 205 moves to the appropriate position, the limiting piece 205 drives the tear strip 203 whose limit has been released to move in the opposite direction. When the tear strip 203 moves, the first adhesive layer 202 at its lower end will gradually release the connection with the film body 1, and at the same time, the two sealing strips 206 at the lower end of the tear strip 203 will move synchronously. When the tear strip 203 moves to the set position, the serrations 207 on the outside of the tear strip 203 will further reduce the force required for tearing, so that the operator can tear the film more easily along the predetermined path. The reinforcing ribs 208 inside the tear strip 203 improve the tearing resistance of the tear strip 203 and prevent the tear strip 203 from breaking during the tearing process, so that the operator can easily and quickly open the package without using tools and tearing laboriously.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
