Description

Technical Field

[0001] The invention relates to the technical field of green environmental protection bags, in particular to a method for preparing a packaging bag. Background Art

[0002] Plastic bags are indispensable items in people's daily lives and are often used to hold other items. They are widely used because of their advantages of being cheap, extremely light, large in capacity, and easy to store. However, they are banned from use and production in some countries because of their extremely long degradation cycle and difficult handling. The use of biodegradable starch materials and natural fibers to prepare degradable plastic bags has become a hot topic of research in countries around the world. However, while starch materials and natural fibers improve the degradability of plastics, they also have many problems. On the one hand, they will cause a decrease in their physical and mechanical properties, low mechanical properties, insufficient load-bearing pressure, and cannot be repeatedly used and carried. In addition, they are too hydrophilic and have poor compatibility with most general resins, resulting in a significant decrease in the mechanical properties of the film and poor water-blocking properties. On the other hand, natural fibers have poor environmental resistance compared to glass fibers, such as poor antimicrobial properties, which hinders the widespread application of plastics made from starch and natural fibers in the process of industrial promotion.
