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.
These pressure seal liners do not require an induction machine.
