Bag packaging is the most common type of secondary packaging, which is widely used in cosmetics, pharmaceuticals, and food industries. It is made of two pieces of aluminum foil roll film packaging material after hot sealing and cutting at high temperature, and can be used to fill water, lotion, oil, cream, etc., with high dosage form adaptability and large filling capacity flexibility. The advantages of aluminum foil packaging, such as its long history, mature technology, and high production efficiency, have made it a favorite in the market. In 2010, YOUNGFACE began developing special-shaped aluminum foil bag packages. On the basis of conventional aluminum foil bag packaging, the expression and value of bag products are enhanced through mold innovation, membrane bag material upgrade, cutting process improvement and other ways.
