This is the name of the inliner/seal we use in our lids. The Pressure Sensitive Seal is easy to apply by applying force by closing the lid. As a result, a protective layer and first user guarantee is printed on the Dutchie. When the package is first closed, the pressure from the lid activates the adhesive, creating a seal between the seal and the rim of the jar. No heating is required to seal Dutchies with the lid and inliner.
