How to develop environmentally friendly plastic bags

- Feb 02, 2018-

Is it worth the value of environmental protection? I consulted on this issue in materials science, experts and PhDs, they think this issue do not have to worry about, because of food shortage, the food prices will naturally rise. The cost of polylactic acid resin for PLA plastic production will also increase, which will to a certain extent inhibit the demand of bioplastic packaging products. This market itself has some regulatory function. In the long run, the traditional plastic raw materials come from non-renewable petroleum resources, which is the rule to be eliminated. The main component of polylactic acid is carbohydrates. Carbohydrates in nature, such as starch and sugar, are easier to get from crops (cheaper), especially corn. It is hoped that future technologies will gradually change this food-dependent situation.
