Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a degradable environmental protection packaging box. Background Technique

[0002] Polylactic acid (PLA) is a new type of bio-based and renewable biodegradable material, which is made from the starch raw materials extracted from renewable plant resources (such as corn, cassava, etc.). The starch raw materials are saccharified to obtain glucose, and then glucose and certain strains of bacteria are fermented to produce high-purity lactic acid. Then, polylactic acid with a certain molecular weight is synthesized by chemical synthesis methods. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use, and finally generates carbon dioxide and water without polluting the environment, which is very beneficial to environmental protection. It is considered to be the most promising green packaging material, and most of the existing packaging boxes are made of PLA material.

[0003] However, most of the packaging boxes have a single variety, basically a simple box structure, with a partition groove of a unified specification arranged inside, and the internal space is relatively fixed, making it difficult to adjust the internal placement space according to products of different sizes, and the space cannot be flexibly changed during recycling.
