AI Technical Summary
Existing food packaging films are prone to irregular cuts when torn, making it difficult to find the outermost end of the next film, which is time-consuming and labor-intensive.
The membrane structure is designed with an elastic pinch band. The pinch band automatically curls into an arch shape when the membrane is separated. Combined with the design of the first and second tear holes, it is easy to find and tear off the next membrane. When using it, you can easily tear it by pinching the pinch section.
This makes the food packaging film easy to use, saving time and effort. The pinch section serves as the force application point, making it even simpler to tear off the next film.

Abstract
Description
Food packaging film Technical Field
[0001] This utility model relates to the field of membrane technology, specifically to food packaging film. Background Technology
[0002] Food packaging film is a polymer material used to wrap the surface of food to isolate it from decomposing microorganisms, bacteria, and foreign contaminants, thereby preventing and prolonging food spoilage.
[0003] Currently, existing food packaging films are usually rolled into a tube. When needed, the outermost end of the film is pinched and lifted, and then torn to the desired length. The torn film is then placed on the food surface to achieve its effect. However, food packaging films are usually thin films with poor slipperiness. After tearing off one sheet of film, the outermost end will have a broken section. This section has an irregular structure and will stick firmly to the remaining film, making it difficult to peel off. Therefore, when tearing off the next sheet, it is difficult to find the outermost end and peel it off, resulting in a cumbersome, time-consuming, and laborious operation. Summary of the Invention
[0004] The purpose of this invention is to provide a food packaging film to solve the above-mentioned problems.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a food packaging film, comprising several interconnected film bodies, wherein a pinching section is provided on one side of each film body, and a connecting section for adhering to the pinching section is provided on the other side; the pinching section comprises several pinching strips, the pinching strips being elastic; when adjacent film bodies are connected, the cross-section of the pinching strip is rectangular, and when adjacent film bodies are separated, the cross-section of the pinching strip is arc-shaped.
[0006] As a further feature of this invention, the connection between the pinching section and the membrane body is provided with a plurality of first tear slits along the width direction, and the connection between the connecting section and the membrane body is provided with a plurality of second tear slits along the width direction.
[0007] As a further feature of this invention, the cross-section of the second tear is rhomboid.
[0008] As a further feature of this invention, the membrane body includes a first base layer and a second base layer, both of which are made of PE material.
[0009] As a further feature of this invention, an intermediate layer is provided between the first base layer and the second base layer, and the intermediate layer is made of EVA material.
[0010] As a further feature of this invention, both the first and second base layers are coated with an anti-scratch coating.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] When separating interconnected film sheets, the pinching section becomes the outermost end of the entire food packaging film roll. Since the pinching strip is freed from the connecting constraints, it automatically curls up, changing from a long strip to an arched shape, making it easy to find. When it is necessary to tear off the next film sheet, simply pinch the pinching section and apply force to easily tear off the film. The pinching section can serve as a force application point, making the operation more convenient, simple, time-saving, and labor-saving. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please refer to Figures 1-3. The food packaging film includes several interconnected film bodies 1. A pinching section is provided on one side of the film body 1, and a connecting section 2 for adhering to the pinching section is provided on the other side. The pinching section includes several pinching strips 3, and the pinching strips 3 are elastic. When adjacent film bodies 1 are connected, the cross-section of the pinching strip 3 is rectangular. When adjacent film bodies 1 are separated, the cross-section of the pinching strip 3 is arc-shaped. When the interconnected film bodies 1 are separated, the pinching section becomes the outermost end of the entire food packaging film roll. Since the pinching strip 3 is freed from the connecting constraint, it will automatically curl up, changing from a long strip to an arched shape, making it easy to find the pinching strip 3. When it is necessary to tear the next film body 1, simply pinch the pinching section and apply force to easily tear off the film body 1. The pinching section can serve as a force application point, making the operation more convenient and simple, saving time and effort.
[0020] Please refer to Figures 2 and 3. Several first tear slits 4 are provided along the width direction at the connection between the pinching section and the film body 1, and several second tear slits 5 are provided along the width direction at the connection between the connecting section 2 and the film body 1. When separating adjacent film bodies 1, the pinching section can be separated from the film body 1 along the first tear slits 4, and the connecting section 2 can be separated from the film body 1 along the second tear slits 5. This makes it easy to separate adjacent film bodies 1, making the use of food packaging film more convenient. The cross-section of the second tear slit 5 is rhomboid, thus ensuring the easy tearing of the second tear slit 5.
[0021] Please refer to Figure 4. The membrane 1 includes a first base layer 6 and a second base layer 7. Both the first base layer 6 and the second base layer 7 are made of PE material. PE material has good flexibility and strong tensile strength, thereby improving the strength and durability of the membrane 1. An intermediate layer 8 is provided between the first base layer 6 and the second base layer 7. The intermediate layer 8 is made of EVA material. EVA material has good elasticity and toughness, thereby further enhancing the tensile strength of the membrane 1. The surfaces of the first base layer 6 and the second base layer 7 are coated with an anti-scratch coating 9, making the surface of the membrane 1 less prone to scratches and improving its durability.
