PET Release Film — Silicone-Coated Polyester Film in 25-100μm
PET release film is biaxially-oriented polyester film coated with silicone, used as a high-strength carrier for adhesive converting, die-cutting and lamination.
- 25-100μm thickness range
- Release force 3-80 g/25mm (±3g)
- High tensile strength & dimensional stability
- Factory direct

PET vs PE Release Film vs Paper Liners
Choose by application, not by catalogue order.
| Dimension | Option A | Option B | Option C |
|---|---|---|---|
| Tensile strength | Highest | Medium | Lowest |
| Heat resistance | Excellent | Good | Limited |
| Cost | Premium | Mid | Most economical |
| Transparency | High | Medium | Opaque/translucent |
| Typical use | Die-cutting, lamination, electronics | Flexible converting | Labels, general tape |
Bottom line: PET for high-tension & heat; PE film for economy & flexibility; paper for cost-sensitive labels.
