Liners and Seal Discs

Liners and seal discs are inserts placed inside a cap to create a secure, airtight, or tamper-evident seal between the closure and the container. Container and Packaging offers wholesale liners and seal discs including induction liners, foam liners, pressure-sensitive liners, and pulp liners, commonly used across the pharmaceutical, food and beverage, cosmetic, chemical, and nutraceutical industries. Selecting the right liner depends on the product being sealed, the closure material, and whether induction sealing equipment is part of the filling line. In packaging, a good seal is the difference between fresh and finished.
