31mm Two-Piece Induction Seal Liners for PE & PP Containers

These 31mm two-piece induction seal liners are designed for PE and PP bottles, providing a secure, tamper-evident seal with the added benefit of a resealable backing liner. After the induction sealing process, the foil layer bonds to the container while the backing liner remains inside the cap for continued sealing performance.

This makes two-piece liners ideal for applications where products are opened and closed multiple times while maintaining product integrity.

Why Choose Two-Piece Induction Liners?

Two-piece induction liners are ideal when resealability is important. After the foil seal is removed, the backing liner remains in the cap, allowing the container to be closed again for continued use.

31mm liners are typically used for larger bottle openings, making them a great choice for products that are accessed frequently or sold in bulk quantities.

Two-Piece vs One-Piece Liners

• Two-piece liners: Resealable, backing stays in cap

• One-piece liners: Single-use seal, no reseal function

If your product requires repeated use after opening, two-piece liners are the better option.
