Aluminum foil bags are also called pure aluminum bags. Aluminum foil bag packaging usually refers to aluminum plastic composite vacuum packaging bags. Such products are suitable for moisture-proof, light proof and vacuum packaging of large precision mechanical equipment, chemical raw materials and pharmaceutical intermediates. The four layer structure is mostly adopted, with good water and oxygen isolation functions.

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.
