Printing Exposure
Specify printing technology and the temperature reaching the laminate during drying. Include dwell and tension where they influence backing behaviour.
Laminate Flatness
Check curl and dimensional change after representative humidity and temperature conditioning, using the complete film, adhesive and liner construction.
Cutting and Transfer
Assess fine-detail weeding, backing damage and application-tape interaction. Verify the intended order of separation before installation.
PCK and CCK Papers Compare these coated papers for printable films and sheet graphics. Assess laminate flatness after printing and conditioning rather than relying on category alone.
Glassine and SCK Papers Consider dense paper backings for suitable roll graphics. Verify kiss cutting, weeding and separation with the chosen film and adhesive.
PET Film Backings Evaluate PET where a film backing fits dimensional or visual requirements. Check printing exposure, converting and final removal on finished samples.
Does PCK guarantee flat graphics?
No. Curl depends on the complete laminate, moisture balance and processing history. Validate the chosen grade in the intended roll or sheet format.
Can a standard liner create air-release channels?
Channel formation requires a specifically designed surface or process. Provide the required pattern and confirm that capability separately before selecting a backing.
Why should application tape be included in testing?
Its adhesion and removal sequence affect whether cut shapes transfer correctly. Trial the graphic film, adhesive, liner and application tape together.
Send the film and adhesive specifications, printing and drying route, graphic dimensions and current backing. Include cutting, flatness, transfer-tape and installation requirements.
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.
