These polypropylene caps have a 0.002" high-quality EVA-wax type pressure-sensitive adhesive coated on 0.020" Foamseal (Extruded Foamed Polystyrene), which itself contains a release coating on the backside. They are designed to be used as an inner seal to seal solid products, such as dry foods and pharmaceuticals. The liner will provide a tight inner seal on both glass and plastic bottles. The sealability of the product is related to the surrounding temperature, application torque, and the age of the product, especially when the pressure-sensitive adhesive coating is exposed to air and light. Users are urged to re-test for their specific application before use.
