Recently, the city of Kassel, Germany, introduced biodegradable bio-packaging bags made of corn or potato starch, whose appearance is no different from ordinary box packaging.
The use of biodegradable bio-packaging bags saves the cost of expensive petroleum, while at the same time it can reduce the environmental damage caused by ordinary plastic boxes. The six local "Tegut" food malls have further strengthened the promotion of biodegradable bio-box bags. The shopping mall not only packs food and vegetables in degradable bio-packaging bags, but also sells food bags made from starch, garbage bags, shopping bags and various beverage cups.
However, as far as technology is concerned, the cost of producing biodegradable bio-packaging bags is 3-4 times higher than that of ordinary plastic films. For national promotion, there is still a certain degree of difficulty.
