The Heat Induction Seal is a multi-layer liner designed for use with induction sealing equipment to create a hermetic, tamper-evident bond between the liner and the container’s neck finish. Once heat is applied by an induction sealer, the foil-laminate structure fuses to the bottle opening — forming an airtight, leak-proof seal that is virtually impossible to reseal without visible evidence of tampering.

At 0.23mm thickness, this liner is engineered for precision induction sealing applications across the food, beverage, pharmaceutical, nutraceutical, and specialty chemical industries. Available in tailored sizes to match your specific cap diameter and bottle neck, heat induction seals from Nextech Packaging are a high-performance solution for brands that prioritize product safety, shelf life, and consumer confidence.
