What is Both Side Siliconized PET Release Film?
Both Side Siliconized PET Release Film is a high-performance polyester-based film with silicone coating applied to both surfaces. It is engineered to deliver consistent release performance and reliable adhesion retention, even under high-temperature conditions. This film is available in clear and ultra-clear variants and is widely used in adhesive processing, label stock, and window films.

Applications of Both Side Siliconized PET Release Film
- Window film
- Solar window film
- Self-adhesive materials
- Labels
- Graphic arts
Features & Benefits of Both Side Siliconized PET Release Film
- High residual adhesion rate for strong and reliable bonding
- Consistent and stable release force across applications
- Excellent heat resistance suitable for thermal processing
- Superior surface smoothness for clean converting
- Dual-side coating enhances versatility and lamination performance
Comparison with Other Adhesive Tapes
- Unlike adhesive tapes, this release film is used to separate layers in adhesive constructions
- Offers greater dimensional stability and higher thermal resistance than paper-based liners
- More versatile in high-speed or high-temperature lamination than single-sided release films
- Provides better surface control and smoother processing than typical backing liners
