Easily-tearing packaging bag

Abstract

The invention provides an easily-tearing packaging bag which comprises a bag body. A PE film layer is arranged on the inner layer of the bag body in a covering mode. The bag body is formed by a bag front face, a bag back face, two side faces and a bottom face in a sealing-packaging mode. The side faces of the bag body are double-layer folding layers. The top end of each side face of the bag body is arranged on the inner side of the back side face of the bag body through sealing paper in a sealing mode. A zipper mechanism is arranged at a top end sealing portion of the front side face of the bag body in a sealing mode. The zipper mechanism comprises concave strip paper and convex strip paper. A convex strip is arranged on the convex strip paper. A concave strip groove matched with the convex strip is formed in the concave strip paper. The zipper mechanism and the bag body are sealed, plant fibers are used as an inner layer of the bag body so that safety and non-toxic performance of food can be guaranteed, a pulling strip is made of jagged lines directly so that resources can be saved, waste can be lowered, cost can be lowered, the fact that the sealing performance of the bag body is great through bonding paper, accordingly, labor is saved through the bag, using is convenient, and cost is lowered.

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
