One piece heat induction foil seals are one of the best ways to keep products safe. They provide a hermetic seal on a closure that helps prevent leaking, spilling, or the introduction of contaminants. A good seal can also preserve product freshness. All heat induction seals need a heat induction machine to seal properly. These materials comply with FDA regulation for food contact.

Pres-On offers several types of heat induction seals depending on the container and product. There are cap liners designed to work with all bottle types; these are labeled for use on universal bottles. Pres-On also offers container seals designed to work with PE bottles, PET bottles, and glass bottles. Cap liners that are designed to work with a specific material will bind more aggressively than a universal liner while still allowing an easy clean peel.

We offer tamper-evident seals that do not peel off cleanly. When compared to clean peel seals, tamper evident seals are often more difficult to remove, or puncture the foil They leave behind evidence that the liner was tampered with.

Additionally, Pres-On offers heat induction foil seals with added barrier layer for sealing aggressive products.  These seals are board or foam backed. Different lid seals are designed to work with PE bottles, PET bottles, or glass bottles. Barrier foil seals are suggested for applications that require added barrier protection for aggressive products (chemicals, oils…etc.).
