QINGDAO BEAUFY GROUP will provide you with information releases and displays related to degradable handbag manufacturers. Please pay attention! What is the future of environmental plastic bag industry?


At present, under the big policy of vigorously advocating environmental protection, in the environment of building green mountains and clean water, environmentally friendly plastics, as the only product that can replace ordinary plastics, will be widely produced and applied. Today, Xiaobian will share with you some of the knowledge I have mastered so far.


Environmental protection plastics are actually degradable plastics. The advantage of degradable plastics is that they can be degraded by microorganisms existing in nature under certain conditions, so as to be completely degraded into water and carbon dioxide. No pollution to the environment, is completely environmentally friendly materials. In China, the market size of plastic bags is 69.8 billion US dollars, and the market size is about 140 billion yuan based on the 30% replaceable rate of degradable plastic bags.

Degradable plastic products are widely used, only degradable plastic bags this one, the future market scale will reach one trillion yuan level.

PLA and PBAT are the main development directions of degradable materials in the future. PLA is one of the most common degradable plastics, and the production process is pollution-free. It is a new type of bio-based and renewable biodegradable material, which is fully biodegradable and can be thermoplastic processed.

In addition to biodegradation, the product made of polylactic acid also has high strength, high transparency, good heat resistance and strong plasticity. The more polylactic acid, the stronger the pearlescent color on the surface of the product, and the smoother the feel. Polylactic acid has antibacterial and anti-mildew effect, can be directly loaded food.


PBAT is a copolymer of p-adipate and p-lactalate, which has excellent biodegradability and is one of the best biodegradable materials in the research and market application of biodegradable plastics. PBAT is a flexible material with heat resistance, excellent ductility and toughness, easy to dry and blow film. PLA combined with PBAT improves the toughness of PLA and shows the complementarity of the two, but the simple incompatibility of the two blends is a major topic that experts have been committed to research.
