With the rapid development of the yogurt industry, innovations in packaging technology have become a focal point of the sector. Among these, composite aluminum foil sealing lids have gained increasing popularity due to their outstanding performance.

What is a Composite Aluminum Foil Sealing Lid?

A composite aluminum foil sealing lid is the cover applied to yogurt cups or yogurt containers. It is primarily made from 8011 aluminum foil, supplied in an annealed state, which provides excellent ductility and softness, making it easy to process and shape. This type of sealing lid is designed for sealing and light-blocking, helping to maintain yogurt freshness and extend its shelf life.

Structure of a Composite Aluminum Foil Sealing Lid for Yogurt

The core structure typically consists of three layers: Polyester (PET), Aluminum Foil (AL), and a Heat-Sealing Layer (PE·EVA).

(1)Polyester (PET) – Serves as the outer layer, providing good transparency and mechanical strength, protecting the inner aluminum foil from external damage.

(2)Aluminum Foil (AL) – The key layer of the yogurt lid, offering excellent oxygen barrier properties to prevent oxidation and spoilage. Additionally, aluminum foil provides superior heat-sealing and antibacterial performance, ensuring yogurt hygiene and safety.

(3)Heat-Sealing Layer (PE·EVA) – This layer connects the yogurt lid to the yogurt cup through heat sealing. Made of polyethylene (PE) or ethylene-vinyl acetate copolymer (EVA), it ensures strong sealing performance and adhesion.
