Various materials with different characteristics are combined to improve the air permeability, moisture permeability, oil resistance, water resistance and drug resistance of packaging materials, so that they can play a role in insect prevention, dust prevention, microbial resistance, light, smell and other odor isolation, and heat resistance, cold resistance, impact resistance have better mechanical strength and processing applicability, and have good printing and decoration effects.

The commodity nature of packaging itself is becoming more and more significant. It has become a special product that is no longer attached to the production of goods, and a product that can not be separated from all goods and is widely used.

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

Packaging bag refers to the bag used to pack various articles, so that the goods can be easily transported and stored in the production and circulation process. It is widely used in daily life and industrial production. The actual figures show that 80% of the used plastic bags are finally transported to the garbage dump area for treatment like ordinary garbage, and only 7% of the plastic is recycled.
