Replace the ordinary plastic bag with starch bag

In the real life, people are always afraid to come into contact with toxic plastic. But if we tell you that the plastic bag can be used by starch, are you be afraid? The National People's Congress, Jiangnan University Vice President, State Key Laboratory of Food Science and Technology Jin Zhengyu put the promotion of the use of starch bags recommended to the venue.

A survey shows that China's annual oil production and imports of about a quarter of the production of plastic products, of which about 30% produced to make food packaging, disposable tableware, shopping bags, etc., and about 40% of the products will become "white pollution", which caused the enormous pressure on the environment. So plastic recycling polystyrene recycling is very necessary to protect our environment. And then we can reuse it to do some other products.

 Jin Zhengyu told reporters that many countries in the world have introduced varying degrees of plastic restrictions to encourage bio-based materials in the field of food packaging applications. If China's food packaging bags can be replaced with biological-based materials, not only can effectively control the "white pollution", but also to the safety of the human body.

Compared to cheap plastic bags, many people worry that bio-packaging bags are too expensive to use. For this worry, Jin Zhengyu smiled and told reporters: "With starch manufacturing bags in the technology has been relatively mature, and now the national corn stocks are high, corn starch prices are very cheap.We measured, according to traditional plastic 20% starch-based materials Alternative, theoretically every year there will be more than 20 million tons of market demand.To blown film end products starch content of 30%, plastic, injection molding end products starch content of 50% or more, is expected to consume 800-1200 million starch per year Ton, the conversion of corn 1150-1700 million tons of cost and the current plastic bag is almost the same.
