Structure:  Paperboard + Aluminum Foil + Heat Seal Layer | Model: BP-320

The BP-320 is a premium two-piece induction seal liner designed for tamper-evident packaging and superior product protection. This 2-in-1 construction combines a paperboard backing with an aluminum foil sealing layer, creating a reliable hermetic seal that extends shelf life, prevents leaks, and provides clear tamper evidence.

During induction sealing, the aluminum foil layer generates heat through electromagnetic induction, bonding securely to the container mouth. The paperboard backing separates and remains inside the cap, serving as a resealable liner for repeated use after opening. This design is widely adopted in pharmaceutical, food, cosmetic, and chemical industries for its balance of security and consumer convenience.
