Vacuum packaging bags are specialized bags designed to remove air from the packaging, thereby extending the shelf life of perishable goods. These bags are typically made from multi-layer films that provide a barrier to moisture, oxygen, and light, which helps in preserving the quality of the food products stored within. They are widely used in the food industry for packaging meat, vegetables, fruits, and other agricultural products.
