Heat Transfer Clear PET Release Film

We are a manufacturer of heat transfer clear pet release film for textile logo transfer, heat transfer labels, and screen or offset printed graphics. This clear PET carrier film supports ink and adhesive layers during printing, drying, stacking, and heat pressing, then separates cleanly after application. It is made for stable peeling, clean logo edges, controlled matte or glossy surface effect, and consistent results in repeated heat transfer production.

Product Overview

This heat transfer carrier film is used when printed artwork needs to stay flat before pressing and release cleanly after pressing. In a real transfer line, the carrier is not just a transparent base. It must hold ink layers, white backing, glue coating, or adhesive powder without causing image movement during drying, stacking, or feeding. After heat pressing, the coated side should let the logo stay on the fabric surface without drag marks, broken edges, ghost marks, or uneven lifting.

Films Protection Company produces this PET transfer release film for workshops that need stable handling from sample testing to batch production. In our workshop sample checks, 75um carrier usually handled fine letters, tagless neck label details, and narrow logo strokes better than thinner grades because it was less likely to curl during drying and sheet feeding. Hot peel grades help faster production. Cold peel grades are often tested for thicker logos, soft-hand labels, or detailed graphics because cooling time helps the printed layer settle before removal.

Benefits

• Stable carrier during printing:The PET base supports printed layers through screen printing, offset printing, drying, stacking, and heat pressing.
• Cleaner logo separation:Controlled coating helps reduce ink drag, dirty edges, ghost marks, broken fine lines, and uneven edge lifting.
• Hot peel and cold peel choices:Hot peel supports faster workflow, while cold peel helps detailed or thicker designs separate after cooling.
• Controlled surface result:Matte, semi-matte, and glossy finishes can affect the final hand feel and visual effect of the transferred logo.
• Better registration control:In-house sample checks showed lower visible image shift when PET shrinkage stayed within <=1.2% under 150 C for 30 minutes.

How does release stability affect clean logo transfer after heat pressing?

Release stability affects whether the printed graphic leaves the PET carrier smoothly or becomes damaged during peeling. When the release force is too light, small letters may shift during printing, storage, or pressing. When it is too strong, the logo edge may stretch, crack, or lift unevenly from the textile surface. In controlled heat press sample checks, a release range around 8-18 g/25mm is often used as a starting reference, but the final grade still needs to match the ink, adhesive, fabric, pressure, cooling time, and peel angle.

Applications

• Tagless neck labels for T-shirts, underwear, sportswear, and workwear
• Textile logo transfer with hot peel or cold peel grades
• Screen printed graphics with fine text or multi-color artwork
• Offset transfer printing for sharp logos and decorative garment marks
• Chest prints, sleeve marks, care labels, and fashion brand graphics
• Transfer printing for cotton, polyester, blended garments, sportswear fabrics, and label substrates after sample validation

What is the difference between matte and glossy transfer finish on PET carrier film?

Matte and glossy finishes should be judged by the final transferred logo, not only by looking at the carrier surface. A matte coating can create a softer, lower-glare effect, which is useful for neck labels, sportswear marks, and fashion logos that should not look too plastic on fabric. A glossy surface can make colors appear cleaner and brighter, especially for decorative graphics or brand marks that need stronger contrast.

FAQ

What makes this carrier different from a simple transparent PET sheet?

It is made for heat transfer production, so it must support ink and adhesive layers before pressing and separate cleanly after heat application.

Can the film support both hot peel and cold peel?

Yes. Different grades can be made for hot peel, cold peel, or hot/cold peel use, depending on ink, adhesive, fabric, and production speed.

What should be tested before mass production?

Thickness, release force, peel timing, finish, ink compatibility, heat press temperature, pressure, fabric type, drying condition, and peel angle should be tested with the actual artwork.

Why should small letters and fine logos be tested separately?

Fine strokes show release problems more clearly. If the release is unstable, small letters may shift, break, leave dirty edges, or lift unevenly after peeling.
