At present, there is strict standard management for packaging bag manufacturers, and there are also higher standard requirements for the thickness of packaging bags, which also imposes the standard requirements that packaging bags must comply with during production. Packaging Bags are mostly used for packaging clothing, product packaging and other purposes. On the basis of ensuring the appearance, they pay attention to quality and make it less prone to damage; The packaging bags are mostly used in supermarkets, restaurants and other places. The fabric is thinner than the packaging bag and is easily damaged. The transparent packaging bag is also one of them. We choose transparent and odorless non-toxic packaging bags, and should not use colorful bags to hold food. Since the transparent bag is made of new materials, the variegated ones are processed with recycled materials, and the quality is very different. Only by choosing qualified plastic bags can we better protect our health.

When the PP plastic bag is in contact with food with high temperature, it can still be kept from deformation, avoiding putting it into the refrigerator. 3.
