Dimensional Control
Define component tolerances and acceptable carrier change during tension or thermal exposure. Verify the actual part layout after conversion.
Optical Registration
Match liner colour and surface appearance to camera or sensor contrast. Transparency alone does not establish reliable detection.
Surface and Static Limits
Specify contamination limits and any electrical requirements with test methods. Cleanroom, antistatic and optical-grade properties require separate confirmation.
PET Film Carriers Start with PET where controlled film thickness or a film backing is required. Check heat exposure, part detection and removal using production samples.
Glassine and SCK Compare dense paper carriers where dimensional tolerances and cleanliness limits permit. Evaluate edge quality, small-part cutting and waste removal.
CCK and PCK Consider coated paper backings when handling stiffness or the construction calls for them. Confirm cutting precision and surface requirements for the specific component.
Is clear PET always suitable for camera registration?
No. Detection depends on lighting, sensor type, part colour and background contrast. Trial the full combination before fixing the liner colour.
Does PET inherently provide antistatic performance?
No. Antistatic behaviour is a separately specified property. State the measurement method and acceptable range, then confirm the proposed grade.
What should an electronics liner trial include?
Check cutting, waste removal, transfer and bonding in sequence. Include representative storage or heat exposure and any specified cleanliness or electrical limits.
Provide the component drawing, adhesive, dimensional tolerances and cutting method. Add thermal exposure, transfer sequence and measurable cleanliness, optical or electrical limits.
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.
