28mm Pressure Seal Foam Liner (Pack of 250)

Pressure seal liners are a popular choice when an airtight seal is needed. These liners provide a strong bond but are not tamper-evident. These seal liners prevent contamination, leaks and preserves freshness by sealing out air. Seals can be used with glass or plastic and with lined or unlined caps.
