Portable war horse bag

Abstract

The invention provides a portable war horse bag. The bag comprises a bag body; the inner layer of the bag body is coated with a PE (Polyethylene) film layer; the bag body is formed by hermetically packaging a bag body front surface, a bag body rear surface, a bag body left side surface, a bag body right side surface and a bag body bottom surface; pull threads are arranged at the corresponding positions of the side surfaces of the front and rear surfaces of the bag body; the pull threads are packaged by adopting packaging threads. According to the portable war horse bag disclosed by the invention, the bag body is excellent in protection performance, is waterproof and moisture-proof and also has a certain heat insulation effect; the bag is odorless, nontoxic, safe and reliable; by adopting the sealing mode and folding mode, the bag can be manually adhered or directly adhered during production; a machining mode is relatively complex, but 40% of the cost can be further saved based on the existing cost by adopting the mode of folding the bag body.

Description

technical field [0001] The invention relates to the field of packaging bags, in particular to a portable warhorse 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 o...

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

[0005] At the same time, the existing packaging bag manufacturing process is relatively complicated, so the cost is high, and if some leftover materials in the packaging bag are directly thrown away, it will cause a certain amount of waste
