Problems solved by technology

[0002] In food packaging materials, polyethylene film is mostly used for flexible packaging. However, due to the poor barrier property of oxygen in this kind of packaging, the shelf life of food cannot be extended, and long-term contact with food will pollute food, and the quality of food is not good. To ensure that, in the prior art, in order to prolong the shelf life of this packaged food, deoxidizers are used to pack together with the food, and when children eat this packaged food, because they have no relevant knowledge of the toxicity of deoxidizers, accidents of accidental ingestion often occur

Embodiment Construction

[0010] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0011] refer to figure 1 Shown is a schematic structural view of the packaging film implemented by the present invention.

[0012] A kind of packaging film suitable for prolonging the shelf life of food implemented by the present invention is a layered structure, including a composite printing layer 1, a transparent layer 2, a laser layer 3, an adhesive layer 4, an aluminum film 5, a thermal Sealing layer6.

[0013] Wherein, the printing layer is a printing graphic layer, and the material of the transparent layer is one or both of low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear low-density polyethylene, and metallocene-catalyzed polyethylene. High density polyethylene material is preferred in this embodiment.

Abstract

The embodiment of the invention discloses a packaging thin film applicable to prolonging expiration date of foods. The packaging thin film is of a layering structure and comprises a printing layer, a transparent layer, an adhesive layer, an aluminum film and a heat sealing layer which are compounded into one from outside to inside. By the adoption of the packaging thin film, by means of excellent oxygen barrier performance and high ultraviolet ray barrier performance of the aluminum film, the packaging thin film is applied to food packaging films, avoids contamination to the foods and is applicable to packaging of the fluid foods.

Description

technical field [0001] The invention relates to a packaging material, in particular to a packaging film suitable for extending the shelf life of food. Background technique [0002] In food packaging materials, polyethylene film is mostly used for flexible packaging. However, due to the poor barrier properties of this type of packaging, the shelf life of food cannot be extended, and long-term contact with food will pollute the food, and the quality of the food is not good. To ensure that, in the prior art, in order to prolong the shelf life of such packaged food, deoxidizers are used to pack together with the food, and when children eat this packaged food, because they have no relevant knowledge of the toxicity of deoxidizers, accidents of accidental ingestion often occur . Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a packaging film suitable for extending the shelf life of food. It can ef...
