Currently, 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 performance, strong oxidation resistance, good plasticity, and can make the shelf life of food longer. The compatibility of aluminum foil with heat-sealed paint, coupled with the excellent thermal conductivity and stability of metal, makes it an ideal material for the cover and heat sealing of various plastic milk containers.
Heat-sealed foil is mainly made of food-grade aluminum foil, such as 8011-O-state aluminum foil. The product surface is clean, uniform in color, without spots, flat and pinhole-free. It has a huge market prospect for the packaging of dairy products such as fresh milk and yogurt.
