Aluminium Foil For PET Water Lid Cups

Aluminium foil for PET water lid cups 8011 is often use with laminated with other material for packaging of cup lids like yogurt. The cup lid includes a cup cover film main body and an aluminum foil composite layer. From top to bottom, the main body of the cup lid film includes an upper polyester film for carrying the printing layer, a base paper for the thick pad and a thick layer for the pad, the lower polyester film and heat seal layer for isolation and protection. The multi-layer material is compounded to increase its tensile strength, tear strength and impact strength. Moreover, the heat-sealing layer uses modified polyethylene, polyester film, base paper thick layer and modified polyethylene layer, all of which have excellent high temperature resistance properties, so they can be suitable for microwave heating. There is a hole position on the main body of the cup cover film, and the aluminum foil composite layer is bonded and covered on the hole position. The aluminum foil composite layer includes an aluminum foil layer placed on the upper layer and a polyester film placed on the lower layer. The aluminum foil composite layer is easier to be pipetted It is more convenient to use when hard objects are poked into it.

The composition of dairy products is complex, and it is easy to be affected by temperature, oxygen, light, microorganisms, mechanical action, etc., resulting in discoloration, oxidation, damage and deterioration of its products, thereby shortening the shelf life. Most of the yogurt cup lids are made of aluminium foil for PET water lid cups, which is mainly to ensure the high barrier properties of the seal and to meet the easy puncture of the straw. However, if the cover film is too easy to puncture, it will not tolerate the force of external hard objects, resulting in quality problems such as leakage and damage.
