Description

Technical Field

[0002] Packaging bags refer to bags used to package various supplies, which make it convenient to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are eventually transported to garbage dumps for treatment like general garbage, and only 7% of plastics are recycled.

[0003] A compression-free stacking packaging bag provided by publication number "CN218369297U" includes a packaging bag body, and also includes: a bottom plate and two first side plates, the top end of the bottom plate is fixedly connected to a connecting plate, the packaging bag body is fixedly connected to the connecting plate, the first side plate is fixedly connected to a first hinge, the other ends of the two first hinges are fixedly connected to the bottom plate, and four second hinges are fixedly connected to the bottom plate. It is suitable for the technical field of packaging bags. Compared with the existing technology, stacked packaging bags are prone to friction with each other, resulting in wrinkle deformation or even tearing damage. The present design can fold the packaging bag body, close the first side plate and the second side plate and the bottom plate to form a protective shell, and protect the packaging bag body therein, thereby avoiding direct friction of the packaging bag body and making the packaging bag body less likely to be deformed and damaged by friction. The design is relatively convenient to use, more in line with actual usage, and has high practicality.

[0004] The existing squeeze-free packaging bags still have the problem of poor protective performance during use. First, they have no antibacterial function. During long-term use, a large number of bacteria will breed on the surface of the packaging bags, which will cause contamination of the items in the packaging bags. Second, their strength and toughness are poor, which causes the packaging bags to easily deform when squeezed, and even cause damage in severe cases. Third, they do not have good anti-corrosion and waterproof properties, which causes their surface to be easily damaged, shortening the service life of the packaging bags and making them unfavorable for use.
