Description

Plastic bag for food packaging

Technical Field

The utility model relates to a plastic bag production technical field specifically is a plastic bag is used in food package.

Background

Plastic bags, which are bags made of plastics (such as polypropylene, polyester, nylon, etc.) as main raw materials, are essential articles for people in daily life and are often used for containing other articles. It is widely used because of its advantages of low cost, extremely light weight, large capacity, and easy storage.

Among the prior art, in the food packing transportation, generally need place food drying and pack in the carton, and fruit collides with and can cause the juice to flow in long-time transportation, if not handle in time and infect other food along with the juice trickling and cause mould to breed in a large number, if independent bagging then can lead to food consumption nutrients, for example with higher speed peel cellulose degradation, make fruit hardness reduce, still can produce ethanol, let fruit appear the bouquet, in addition, independent bagging can make the steam that breathes and produce not go out completely, can let fruit be in high humid environment, go mouldy easily.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem provided in the above-mentioned background art, the utility model provides a plastic bag for food packaging.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a plastic bag for packaging food comprises an outer bag, an inner interlayer and an inner bag, wherein the outer bag, the inner interlayer and the inner bag are combined by hot pressing; the bag opening of the outer layer bag is provided with a plurality of air holes, and the bag bottom of the inner layer bag is provided with a plurality of water permeable holes.

Furthermore, the inner interlayer is made of artificial fiber materials.

Further, the inner interlayer is a natural fiber fabric.

Further, the inner interlayer is made of cotton fabric.

Further, a heat insulation layer is arranged outside the bag bottom of the outer layer bag.

Compared with the prior art, the beneficial effects of the utility model are that:

place the food that will wait to transport the utility model discloses in, the hole contact of permeating water of its bottom and inlayer bag, the moisture juice that respiration or collided with the production is absorbed by interior intermediate layer from the hole department of permeating water, and the bleeder vent of outer bag can effectively carry out the air exchange with interior intermediate layer, in time carries out the drying to interior intermediate layer, carries out the air exchange with food simultaneously, the freshness of at utmost food. The utility model discloses the structure principle is simple, through setting up the bleeder vent in the top, sets up the hole of permeating water in the below, makes it can carry out the air exchange with the external world when the biggest assurance food is dry, has effectively improved the fresh degree in the food transportation, and the practicality is strong.
