Cup Sealing Foil Lids

Cup sealing foil lids is a material commonly used in food packaging to close cups or containers, and is especially widely used in sealing containers such as yogurt cup lids. The aluminum foil is usually sealed on the lid of the cup with a heat sealing machine to maintain the freshness and hygiene of the food or beverage inside the cup. Heat seal aluminum foil for cup lids is usually laminated with multiple layers of film, and common structures include polyester (PET) layer, aluminum foil (AL) layer, and heat sealable layer (PE/EVA). The heat sealing layer can form a seal with the surface of the cup when using a heat sealing machine. This composite structure makes the aluminum foil film have both barrier and good heat sealing properties.
