Bio-polymer For Biodegradable Bag

Oct 30, 2017

Biopolymers are not actually available now, as early as the early 20th century, people had produced cellulose films or cellophane with pulp. However, although cellulose films are based on biological sources, they are not composting. It is not composting at least when it is tested with the latest standards. The certification of composting is a key requirement of today's environmentally conscious market for biopolymers, especially for bio-polymers used in packaging.Biodegradable Bag

While we must strike a proper balance between market and technological advantage, the fundamental problem is cost, because all the plastic based on renewable resources is more expensive than conventional polymers. "There is also a problem with food packaging, which is that the gas and moisture resistance of bioplastics are relatively low, sometimes affecting the freshness and preservation of food." Breakthroughs in the application of biopolymers are most likely to appear in the packaging market, and most likely in food packaging. "Because our products are easy to replace pet, we have about 80% of the market in terms of packaging," he said. The market has naturally created a pull power.Biodegradable Bag

Under the action of microorganisms, it can be completely decomposed into the plastic of low-molecular-weight compounds. It is characterized by convenient storage and transportation, as long as the maintenance of dry, do not need to avoid light, wide range of applications, not only can be used for agricultural plastic film, packaging bags, but also widely used in the field of medicine. With the development of modern biotechnology, biodegradable plastics are becoming more and more important, which has become a new research and development hotspot.Biodegradable Bag 

The natural starch molecule contains a large number of hydroxyl groups to form a strong hydrogen bond between molecule and molecule, the molecule polarity is larger, and the polarity of synthetic resin is small, it is hydrophobic material. Therefore, natural starch must be treated to improve hydrophobicity and compatibility with polymers. The two methods of physical modification and chemical modification are mainly used.Biodegradable Bag
