Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a biodegradable and environment-friendly food packaging material, which solves the problem that most of the packaging bags cannot be decomposed after they become garbage, which causes great pressure on the environment and becomes waste after use. The accumulation of food has become one of the main pollution sources of urban production and living environment, and it has no antibacterial effect on packaged food, which is harmful to consumers' health, and has low storage performance.
