A puncture-resistant food packaging film

Abstract

This utility model discloses a puncture-resistant food packaging film, relating to the field of food packaging film technology. The utility model includes a packaging film body. A first extension block is integrally formed on one side of the bottom of the packaging film body, and a through hole is formed on one side of the first extension block. A second extension block is integrally formed on the other side of the bottom of the packaging film body, and a groove is formed on one side of the second extension block. A hook is fixedly installed in the groove. The hook and the through hole are used to cooperate when the packaging film is folded. After folding, the hook engages with the through hole. Due to the elasticity of the packaging film material, an unfolding rebound force is generated, causing the hook to press against the inner wall of the through hole, achieving mechanical interlocking. The packaging film body includes a substrate. This utility model can limit the folded packaging film, preventing it from unfolding, reducing the space occupied by the packaging film, improving the structural strength of the packaging film, reducing the possibility of puncture by sharp objects, and providing protection for the food inside.

Description

Technical Field

[0001] This utility model belongs to the field of food packaging film technology, and in particular relates to a puncture-resistant food packaging film. Background Technology

[0002] Food packaging film is a polymer material used to wrap food to isolate it from microorganisms and contaminants, preventing spoilage. It comes in various types and is widely used in the food industry. Its core functions are to protect food quality, extend shelf life, and facilitate transportation and sales.

[0003] In existing technologies, to prevent packaging films from being punctured by sharp objects, they are usually thickened or made of polymer materials. However, due to the material properties, these types of packaging films have poor folding properties, easily unfolding after folding, taking up space in the trash can, and are inconvenient to use.

[0004] Therefore, we propose a puncture-resistant food packaging film. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing packaging films have poor folding effect due to their material properties, are easy to unfold after folding, occupy space in the trash can, and are inconvenient to use. Therefore, this invention proposes a puncture-resistant food packaging film.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A puncture-resistant food packaging film, comprising: The packaging film body has a first extension block integrally formed on one side of its bottom, and a through hole is opened on one side of the first extension block; The second extension block is integrally formed on the other side of the bottom of the packaging film body. A groove is provided on one side of the second extension block, and a hook is fixedly installed in the groove. The hook and the through hole are used to cooperate when the packaging film is folded. After folding, the hook is hooked into the through hole. Due to the elasticity of the material of the packaging film body, an unfolding rebound force is generated, which makes the hook press against the inner wall of the through hole to achieve mechanical interlocking. The main body of the packaging film includes a substrate, and a first puncture-resistant layer, a second puncture-resistant layer and an abrasion-resistant protective layer are sequentially disposed on one side of the substrate. The first puncture-resistant layer and the second puncture-resistant layer work together to resist puncture impact.

[0007] In one possible design, the substrate is made of PET, the first puncture-resistant layer is made of PA, the second puncture-resistant layer is made of RCPP, and the abrasion-resistant protective layer is made of PVC.

[0008] In one possible design, the bottom side of the packaging film body has two printing areas, located on one side of the first extension block and the second extension block, respectively.

[0009] In one possible design, the top of the packaging film body is provided with a heat-sealed edge.

[0010] In one possible design, a hanging hole is provided through one side of the heat-sealed edge.

[0011] In one possible design, an easy-tear opening is provided on one side of the main body of the packaging film.

[0012] In this application, when folding, the packaging film is folded to a certain width. After being fully folded, it is folded in half, and then the hook is passed through the through hole. Due to its own material characteristics, the packaging film has a tendency to unfold automatically, so that the hook can stably hook the through hole, ensuring the limiting effect of the folded packaging film and preventing the packaging film from unfolding.

[0013] Beneficial effects: In this utility model, the puncture-resistant food packaging film, through the setting of through holes and hooks, can limit the folded packaging film, prevent the packaging film from unfolding, and reduce the space occupied by the packaging film. In this utility model, the puncture-resistant food packaging film, through the setting of a first puncture-resistant layer, a second puncture-resistant layer and a wear-resistant protective layer, can improve the structural strength of the packaging film, reduce the possibility of being punctured by sharp objects, and provide protection for the food inside. In this invention, the folded packaging film can be limited to prevent it from unfolding, thus reducing the space occupied by the packaging film, improving its structural strength, reducing the possibility of it being punctured by sharp objects, and providing protection for the food inside.
