  • Cockling-Protecting PSA Release Liners from Heat and Humidity (.pdf)
    Siliconised release liners play a critical role in pressure-sensitive adhesive (PSA) systems, protecting the adhesive during transport and storage and through various converting and assembly processes. To successfully provide this protective function in varying atmospheres, the release liner must
