An easy-to-tear packaging bag

Abstract

The invention provides an easy-to-tear packaging bag, which includes a bag body. The inner layer of the bag is covered with a layer of PE film. , and the top of the side of the bag body is sealed and arranged on the inner side of the rear side of the bag body through sealing paper, and a zipper mechanism is sealed at the top seal of the front side of the bag body. The zipper mechanism includes convex strip paper and concave strip paper, and convex strip paper Convex strips are arranged on the paper, and concave strip grooves matched with the convex strips are arranged on the concave strip paper. The present invention adopts the sealing method of the zipper mechanism and the bag body. The inner layer of the bag is made of plant fiber to ensure the safety and non-toxicity of the food. The knotted paper ensures that the bag is sealed very well, so the bag is more labor-saving, more convenient to use and lowers the cost.

Description

technical field [0001] The invention relates to the field of packaging bags, in particular to an easy-to-tear packaging bag. Background technique [0002] Packaging bags are used to install edible items or small objects, etc. The advantages of using plastic packaging bags are that they have a relatively long service life, save costs, and are light in weight. [0003] In the prior art, in the plastic packaging bag products, the raw materials of the bag are purchased directly, and the inner layer of the packaging bag is covered with a layer of PE film. This kind of film is often not safe to directly hold food. The outer layer of the bag is forcibly pulled apart by the hard plastic strap, and it can be thrown away after being pulled apart. This kind of hard plastic strap is extremely difficult to degrade, and there is little or no recycling, which will increase the cost and increase the cost. The increase of the production process is easy to cause environmental pollution and w...

Problems solved by technology

[0003] In the prior art, in the plastic packaging bag products, the raw materials of the bag are purchased directly, and the inner layer of the packaging bag is covered with a layer of PE film. This kind of film is often not safe to directly hold food. The outer layer of the bag is forcibly pulled apart by the hard plastic strap, and it can be thrown away after being pulled apart. This kind of hard plastic strap is extremely difficult to degrade, and there is little or no recycling, which will increase the cost and increase the cost. The increase of production process is easy to cause environmental pollution and waste of materials

[0004] Generally, the internal space of the existing packaging bag is small, so the capacity is small, and it cannot be sealed in time when the food is not finished, or the sealing effect of the seal is not good. When the joint around the bag is sealed and sealed, it is easy to form air bubbles and wrinkles, so the airtightness is also difficult to guarantee
