Lidding films are the sealing film option for containers—typically food trays, tubs, cups or other rigid or semi-rigid packaging. This category focuses on films engineered for high‐seal performance, maintaining freshness, preventing leaks and extending shelf life. Alte Rego’s lidding films are suited for a wide range of food‐grade applications, delivering consistent adhesion, compatibility with existing packaging lines and options for customization and compatibility with sealing machines. They help brands safeguard product quality, improve consumer perception (via clean seals and attractive appearance) and ensure operational efficiency on the line. For any container-based food product, a reliable lidding film is a critical component of the packaging system.
