Simple and convenient Zhanma bag

Abstract

The invention provides a simple and convenient Zhanma bag. The simple and convenient Zhanma bag comprises a bag body. An inner layer of the bag body is covered with a layer of PE film. The bag body is formed by encapsulating a bag body front surface, a bag body back surface, two bag body side surfaces and a bag body bottom surface in a sealed mode. The bag body side surfaces are double-layer folded layers. Pull lines are arranged on the side of the bag body front surface and the side of the bag body back surface and encapsulated through an encapsulating line. The bag body front surface, the bag body back surface, the two bag body side surfaces and the bag body bottom surface of the bag body are integrally arranged. According to the simple and convenient Zhanma bag, the protection performance of the bag body is excellent, the waterproof effect and the moisture-proof effect can be achieved, and a certain heat insulation effect is also achieved at the same time; the odourless effect, the non-toxic effect and the safety and reliability effects are achieved; in addition, pasting can be directly conducted through manual pasting during production by adopting the sealing mode and the folding mode, and the complex situation caused by a machining mode is avoided; and by means of the bag body folding mode, the cost can be further reduced by 40% on the basis of the current cost.

Description

technical field [0001] The invention relates to the field of packaging bags, in particular to a simple war horse 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 waste of...

[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

[0005] At the same time, the existing packaging bag manufacturing process is more complicated, so the cost is higher
