Bonding Conditions
Record the adhesive, actual material temperature, pressure and dwell. Verify any backing exposure rather than inferring suitability from the substrate name.
Peel Timing
Define whether the liner is removed before bonding, while warm or after cooling. Compare candidates at that same stage.
Fabric Appearance
Inspect adhesive placement, distortion and surface impressions after bonding. A successful peel must also preserve the required textile finish.
Glassine and SCK Candidates Compare dense paper candidates for compatible adhesive transfer or cover applications, checking separation and backing integrity through the defined process.
CCK and PCK Candidates Assess coated papers where handling stiffness or surface structure suits the laminate. For heated processes, confirm grade-specific exposure limits before trials.
PET Carrier Candidates Consider PET when a film carrier is needed for dimensions or visibility. Validate heat-related shrinkage and removal on the actual adhesive and fabric.
Can any silicone release paper be used in heated bonding?
No. Suitability depends on adhesive chemistry, temperature, dwell, pressure and removal timing. Qualification must cover the selected grade and complete bonding cycle.
Is PET release film the same as DTF printing film?
No. DTF film requires specific printing and transfer coatings. Ordinary silicone release film should not be presented as a substitute without a separately qualified product.
Why can the liner work cold but fail when peeled warm?
Adhesive behaviour and interfacial release change with temperature and contact history. Compare materials at the removal stage used in production, including the intended cooling time.
Identify the fabric, adhesive layer, bonding route and removal stage. Add temperature, pressure, dwell and peel timing if the liner experiences heated bonding.
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.
