At present, the lids that are in direct contact with dairy products on the market are mainly made of aluminum foil. Heat-sealed foil has strong permeability resistance, high heat sealing, strong oxidation resistance, good plasticity, and can make the shelf life of food longer. The compatibility of aluminum foil and heat-sealed paint, coupled with the excellent thermal conductivity and stability of metal, makes it an ideal material for capping and heat sealing of various plastic milk containers.

Heat-sealed foil is mainly made of food-grade aluminum foil, such as 8011-O aluminum foil. The product surface is clean, uniform in color, no spots, flat and pinhole-free. It has a huge market prospect for packaging of dairy products such as fresh milk and yogurt.
