White Pressure Sensitive Liner For 50ml Glass Jar (51mm)

50ml Glass Jar Pressure Sensitive Seal Liner (51mm)

Our 51mm pressure sensitive seal liner is designed specifically for use with 50ml glass jars, providing a simple, reliable way to create a tamper-evident style inner seal without the need for heat induction equipment. Designed to create a clean, professional finish, the liner helps protect your products during storage, transport and retail display while providing customers with added confidence that the product has remained sealed until first opening.

After application, the liner typically requires around 24 hours to form a complete seal. This provides more than enough time for product filling, storage, shipping and retail display while giving customers added confidence that the product has remained securely sealed until first opening.

Designed for 51mm Glass Jar Openings

This pressure sensitive liner is manufactured to fit glass jars with a 51mm neck opening. The measurement refers to the internal rim diameter across the full opening of the jar.

It is important that the correct liner size is selected. Using a liner on a jar with a smaller opening may cause the liner to overlap the rim, preventing it from bonding correctly and compromising the seal. For the best performance, always match the liner diameter to the corresponding jar neck size.

If you are purchasing the liner on its own, please note that it measures 51mm. This measurement is taken across the full opening of the jar (the neck opening) and should match your container exactly. While this liner may also be suitable for other 51mm jars, we can only guarantee compatibility with our own 50ml glass jar, which has been tested to ensure the correct fit and sealing performance.

Simple Pressure Activated Application

No specialist equipment is required. Simply place the pressure sensitive liner inside a compatible screw cap with the sealing side facing the jar, fill your container and tighten the lid firmly. The pressure created by the closure activates the adhesive, allowing the liner to bond naturally to the rim of the jar.

For best results, allow approximately 24 hours for the liner to fully adhere before removing the lid. Once the seal has formed, the liner remains attached to the jar when the cap is first removed, providing a professional tamper-evident style presentation that is ideal for manufacturing, shipping and retail sale.
