37.5mm Two-Piece Induction Seal Liners for PE & PP Containers

These 37.5mm two-piece induction seal liners are designed for PE and PP bottles, providing a secure, tamper-evident seal with the added advantage of a resealable backing liner. During the induction sealing process, the foil layer bonds to the container while the backing liner remains inside the cap, allowing the container to be opened and reclosed after initial use.

The 37.5mm size is ideal for large containers and bulk packaging applications where both product protection and resealability are important.

Why Choose 37.5mm Two-Piece Induction Liners?

37.5mm induction liners are ideal for large-diameter container openings, where a wider sealing surface is required for consistent performance. The two-piece design makes them especially useful for products that need to be accessed multiple times after opening.

This size is commonly used in bulk packaging and high-capacity containers, where both durability and resealability are essential.

Two-Piece vs One-Piece Liners

• Two-piece liners:

  • Resealable backing remains in cap

  • Ideal for repeated use

• One-piece liners:

  • Single-use seal

  • No reseal function

If your product is opened frequently after purchase, two-piece liners are the better choice.
