Yogurt aluminum foil lids are a common food packaging material typically used to seal yogurt containers, providing dust protection, contamination prevention, and freshness preservation. These lids are usually made of aluminum foil laminated with a PP film coating. The aluminum foil layer protects yogurt from external factors by blocking light, oxygen, moisture, and other contaminants, preventing spoilage and maintaining shelf life. The PP film coating further enhances the protective capability, ensuring the yogurt stays fresh and flavorful before opening.

Aluminum foil used for yogurt lids is mainly produced from alloys such as 1235, 8011, and 8079 in O-temper (soft temper). This temper provides excellent ductility, making the foil easy to punch-form without rebound or cracking. Typical aluminum foil thickness ranges from 0.04 mm to 0.09 mm. The innermost heat-seal layer (such as PE) is responsible for bonding to the plastic cup rim through heat and pressure after filling, forming a hygienic and leak-proof primary seal.
