Biodegradable material, low-carbon environmental leader, fixed-powder-based biodegradable plastic, is a kind of plastic product, which is formed by mixing fixed-powder with other polymers after toughening and grafting reaction. It can replace common plastics in manufacturing industry, and can be used as packaging materials, shockproof materials, floor film, food containers, toys and so on. The properties of starch are related to the relative molecular weight of starch, the length of amylopectin and the ratio of amylopectin to amylopectin. Let's show you our environmentally friendly tableware.
Experiments show that starch with high amylose content is more suitable for the preparation of plastics, and the products obtained have better mechanical properties. At present, the mechanical properties of starch plastics have basically reached the standard of traditional plastics. However, due to the water absorption of starch itself, the material will absorb water in humid environment, resulting in a serious decline in mechanical properties. The higher the starch content, the more serious the problem. Some starch plastics can even be completely dissolved in water.
For products such as biopolymers, people are interested not only in their biodegradability, but also in other areas, such as oil prices. We have recently seen the price of oil reach a peak, and according to the relevant forecast, we will face 20, 50 or even 100 years of oil shortage. It's not a question of whether it will happen, it's just a matter of time.
Breakthroughs in the application of biopolymers may occur in the packaging market, and more likely in food packaging. "Since our products are easy to replace PET, about 80% of our market is in packaging. The market has naturally created a kind of pulling power.
