Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical maintenance, in particular to a biodegradable express bag. Background Art

[0002] Courier bags refer to bags used for packaging documents, receipts, materials, goods, etc. in the express delivery industry. They are also called express bags, mailing bags, and express packaging bags. The most commonly used plastic courier bags are made of polyethylene materials, which are low-cost, easy to use, and have good waterproof performance. The courier bags are classified according to the material into courier plastic bags, courier document seals, courier bubble bags, courier bone bags, courier woven bags, etc. The courier plastic bags are made of low-density polyethylene, which has the advantages of low cost and light weight; the courier document seals are generally made of gray-bottomed white paper, white cardboard, and cow cardboard. The courier document seals are flat and not easy to break compared to courier plastic bags; the courier bubble bag is a transparent soft packaging bag with air filled in the middle layer of the air cushion film, which has good shock absorption and impact resistance, as well as the advantages of being non-toxic, odorless, moisture-proof, and corrosion-resistant; the courier bone bag is made of polyethylene and high-pressure linear polyethylene through blown film molding; the courier woven bag is also called a snake skin bag, which is a kind of plastic with strong environmental protection and strong recycling efforts.

[0003] Most of the existing large items are packaged in cartons during express delivery. However, during transportation, the cartons may be damaged or scratched by external forces, which will affect the integrity of the packaging and the items stored inside are easily damaged. Most express bags have a layer of plastic material added on the outside, which makes the packaging process cumbersome. In addition, the material of the express bags used is non-degradable and easily affects the environment. It is necessary to design a biodegradable express bag to solve the above-mentioned problems.
