Heat-seal paint milk cap foil refers to a special sealing aluminum foil material commonly used in food packaging, usually used to seal the top of dairy cups such as yogurt and cheese. Milk cap foil generally uses 8011, 1235 or 8079 aluminum alloy because this alloy has excellent forming properties and high strength.
The surface of the aluminum foil is coated with a layer of heat-seal paint, which can melt when heated and tightly bond with other surfaces (usually another layer of material coated with heat-seal paint), so as to achieve a tight bond with the mouth of the plastic cup. This sealing helps to maintain the freshness and taste of the milk cap while preventing the drink from spilling or external contamination. Heat-seal paint is particularly important in food packaging because it ensures that the food inside the package remains fresh and hygienic during storage and transportation.
