Introduction of Hot Sealing Aluminum Foil

Heat sealing aluminum foil is used for packaging dairy products such as fresh milk and yogurt after printing or painting. Heat sealing aluminum foil has excellent sealing performance and corrosion resistance, can protect the products inside from external moisture, oxygen, dust and bacteria, extending the shelf life and freshness of the product. Flait Aluminum produces heat sealing aluminum foil under a professional production system, and its chemical composition and mechanical properties are guaranteed. The mainly heat sealing foils are 8011 aluminum foil and 8079 aluminum foil.
