The role of aluminum foil in aluminum foil packaging bags
Aluminum foil packaging bags have many specifications, not only in different sizes, but also in different thicknesses, which also makes them meet a standard for packaging requirements. The greater the thickness of the aluminum foil packaging bag, the tighter the packaging performance, and the more able to meet the packaging requirements.
When packaging food, composite materials are commonly used, and aluminum foil is added to enhance the air tightness and light transmission of the bag, thereby better protecting the quality of the product.
