History of Development

The commodity nature of packaging itself is becoming more and more obvious. It has become a special product which is no longer dependent on commodity production. It is a product which can not be separated from all commodities and is widely used.

Chinese scientists have developed an environmentally friendly plastic bag made of electrolyte, which can not only be decomposed harmlessly, but also be soluble in water.

According to scientists, it takes hundreds of years for products made of common polymer plastics to be completely decomposed and will exist on Earth for hundreds of years.

The new environmentally friendly plastic bags will not release harmful substances during the decomposition process, and can even be decomposed into natural substances favored by insects. Packaging bags manufacturers have played a great role in protecting the natural environment.
