Coating and Lamination
Record adhesive chemistry and the temperature reaching the liner, including contact time. Equipment setpoints alone may not describe material exposure.
Roll Storage
Check blocking, deformation and release after representative transport and storage. Include the wound membrane rather than testing loose liner alone.
Installer Handling
Evaluate grip, tearing and peeling effort across the specified width. Trial removal at temperatures relevant to the intended installation.
PCK Release Paper Consider PCK where a polymer-coated paper structure is useful for moisture management and handling; validate the full laminate and exposed edges.
CCK Release Paper Compare CCK when backing stiffness and paper handling suit the membrane. Confirm performance after storage and wide-area peeling.
PET Release Film Evaluate PET for film-backed membrane designs. Check dimensional behaviour during coating and the installer’s removal action on representative rolls.
Does the liner provide the installed waterproof barrier?
No. The liner is removed to expose adhesive. Waterproofing performance belongs to the installed membrane system and its specified joints and detailing.
Is room-temperature release testing sufficient?
Not where storage or installation occurs under different conditions. Agree relevant temperature exposures and peel methods using the actual membrane adhesive.
Can a standard liner be supplied with a split?
Specify the split layout and intended supply stage. Slitting, scoring or converted formats require separate confirmation; a backing category alone does not define those capabilities.
Send the adhesive type, coating conditions, membrane width and current backing. Add roll limits, storage conditions, installation temperatures and any split-backing drawing.
HENGMU will exhibit at Adhesives & Bonding Expo Europe 2026 in Stuttgart. Visit Hall 1, Booth 721 to discuss silicone release papers and PET release films for adhesive tapes, foam tapes and industrial converting.
Winter production problems require more than a change in release paper grade. Learn how to assess storage conditions, roll conditioning, static and release force before selecting a different liner.
The establishment of HENGMU’s Malaysian facility and its 2,200 mm PM3 silicone coating line marks a new stage in the company’s manufacturing development in 2026. The expansion adds a production location for release materials and creates further options for international supply planning.
