Adhesive Chemistry
Identify the adhesive formulation first. Standard silicone release coatings must not be assumed compatible with soft silicone adhesives.
Removal Geometry
Check split positions, tabs and overlap on the assembled dressing. The user should expose adhesive in the intended sequence without damaging the product.
Process Qualification
Include relevant sterilisation exposure, storage and supporting records in qualification. Liner approval does not establish conformity of the finished medical device.
Glassine and SCK Papers Start paper-cover trials with Glassine or SCK where the dressing design requires a dense backing; assess cutting, peeling and handling on finished samples.
CCK and PCK Papers Compare CCK or PCK when backing stiffness or a coated-paper structure suits the layout. Confirm compatibility and dimensional behaviour through the relevant process.
PET Film Options Consider PET for film-backed dressing designs needing specified carrier thickness or visibility. Verify removal against film distortion and adhesive disturbance.
Can ordinary silicone release paper cover soft silicone adhesive?
Do not assume compatibility. Soft silicone adhesives may require a specialised release chemistry; confirm the release system through dedicated testing before approval.
Does the liner make a dressing sterile?
No. Sterility depends on the validated device, packaging and sterilisation process. A release liner temporarily covers adhesive and is not automatically a sterile barrier.
Which documents should accompany qualification?
Agree material identification, current technical data, batch traceability and relevant test results. Additional documentation follows the device manufacturer’s requirements and intended manufacturing process.
Send the dressing drawing, adhesive type, liner layout and removal sequence. Include sterilisation exposure, current liner, sample format and documentation required for qualification.
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.
