Przedsiębiorstwo Handlowe JAS

JAS Company, established in 1998 in Łódź, Poland, produces pre-cut discs (liners) for sealing plastic and glass packaging such as bottles, jars, and containers.

Liners are available in three types:

• Primary base liners – Non-induction liners made from co-extruded PE. Designed for initial sealing, shelf life protection, and resealability.
• Induction seal liners – Multilayer liners with an aluminum core film, used for induction sealing. Benefits include leak prevention, consumer confidence, tamper evidence, extended shelf life, safety, security, and protection from contamination.
• Pressure-sensitive liners – Inner seals made of polystyrene foam covered with high-quality pressure-sensitive adhesive. Sealing occurs through torque pressure only—no induction or conduction heating devices are required. They protect the product from humidity and oxygen, extending shelf life and preserving aroma. Not approved for use with wet products.

The liners we offer are widely used in the chemical, pharmaceutical, and food industries. Sealing and encapsulation help extend shelf life, maintain freshness, and protect against counterfeiting.

Liners are available in a wide range of diameters.
