Type of foil lids
Foil lids definition
Foil lids are thin covers made primarily from aluminium foil laminated to a peelable heat-seal layer used to seal containers such as jars, tubs, cups, bottles, and trays. They serve both practical and marketing purposes in many industries, especially food, beverage.
Foil lids types
Foil lids have the same basic functions as easy-peel aluminum foil sealing film, namely heat sealing and easy-peel opening. However, due to the surface embossing process, they appear thicker and more high-end in terms of thickness and feel compared to easy-peel aluminum foil sealing film.foil lids are frequently used in dairy products, food, beverages, frozen foods, nutritional supplements, and other fields.So, how should foil lids be classified? According to the embossing method or appearance characteristics? Perhaps these are the answers that Chat-GDT would give, but in reality, their correct classification should be based on the material of the heat seal lacquer of the foil lids, which should correspond to the material of the container to be heat-sealed.
The heat seal lacquer of this type of foil lids is PS(Polystyrene). The corresponding container material must also be PS, such as cups/boxes used for dairy products, frozen foods, etc., that need to be frozen.
The heat seal lacquer of this type of foil lids is PP(Polypropylene). The corresponding container material must also be PP, such as cups/boxes used for hot beverages, etc., that require hot filling/pasteurization.
The heat seal lacquer of this type of foil lids is PVC(Polyvinyl Chloride). The corresponding container material must also be PVC, such as jars used for nutritional supplements, etc.
The heat seal lacquer of this type of foil lids is PE(Polyethylene). The corresponding container material must also be PE, such as jars/cups/boxes used for snacks, etc., in dry environments.
