These polystyrene jar foam liner seals coated with torque-activated adhesive require no tools and no heat induction equipment.

These 70 mm (2.75 inches) seals are to be used with regular mouth jars that measure 2 3⁄8 in (60 mm) inner and 2 3⁄4 in (70 mm) outer diameter neck size. ● Completely clean the jar top with clean cloth and alcohol to clear of liquid and/or solids. Center jar seal on top of you plastic or glass jar, and apply. The white side of the seal shall be facing down, the side with red letters shall be facing up. ● Screw metal or plastic cap on jar. Make sure the liner and cap are tightly secured on the container. ● Once the cap is applied, it should not be removed for at least 24 hours to ensure proper adhesion. Although depending on your application, the adhesion process might take significantly less time. ● Seals can be used with glass and plastic jars and with lined or unlined caps. These pressure sensitive liners are best for use with powder or dry products. ● Avoid overfilling your containers! ● Once seal is removed, it cannot be reapplied. ● Not suitable for applications containing oil.
