Heat induction seal cap liners are a great way to keep products safe. They provide an airtight seal on a closure that helps prevent leaking or spilling and the introduction of contaminants. A good seal can also preserve product freshness. Pres-On offers several different types of heat induction seals, but the most popular are foil one-piece foam backed seals, pulp board and foil two-piece seals, and Lift ‘n’ Peel™ heat induction seals.

However, attaining a proper seal can sometimes be a challenge if you’re unfamiliar with heat induction. First, guarantee the cap, cap liner, bottle, and product are compatible. The experts at Pres-On can help with this step. Please contact us if you need any help with finding a compatible cap liner. More importantly, to ensure a proper seal the right amount of heat, pressure, and time must be applied. So where do you start?
