Knowledge of packaging bags
The development of packaging bags has gone through four obvious stages: the original packaging bag stage, the large packaging bag stage, the small packaging bag stage, and the current gradually entering a new stage of environmentally friendly (green) packaging bags. With the development of the commodity economy, the commoditity of packaging itself has become more and more significant, it has become a special product that is no longer attached to commodity production, a product that is inseparable 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 soluble in water.
According to scientists, products made of polymer plastic materials commonly found in life take hundreds of years to be completely decomposed and will exist on Earth for hundreds of years. According to actual figures, 80% of used plastic bags are eventually transported to garbage dumps for disposal like ordinary garbage, and only 7% of plastic is recycled and recycled.
This new environmentally friendly plastic bag will not release harmful substances during the decomposition process, and can even be decomposed into natural substances loved by insects, which greatly helps to protect the natural environment.
