Superior Release Properties for Manufacturing Efficiency
Our PET release film offers exceptional release characteristics with consistent peeling force and customizable release levels, ensuring clean separation in various manufacturing processes. The specialized silicone coating provides controlled adhesion that prevents sticking while maintaining sufficient grip during processing. This balance is critical for applications such as ceramic tape casting, where the green tape must remain securely attached during casting and drying but release cleanly during delamination. The film's consistent release properties significantly improve production efficiency by reducing waste and minimizing downtime due to adhesion issues.
Excellent Dimensional Stability and Thermal Performance
With outstanding dimensional stability and heat resistance up to 200°C, this PET release film maintains precise dimensions and flatness throughout high-temperature manufacturing processes. The low thermal expansion coefficient ensures minimal dimensional changes during thermal cycling, which is essential for maintaining registration accuracy in multilayer constructions. This thermal stability is particularly valuable in ceramic tape casting and lithium-battery electrode production, where materials undergo drying and curing at elevated temperatures while requiring precise dimensional control for subsequent processing steps.
Optical Clarity and Superior Surface Quality
Featuring crystal-clear transparency with light transmission exceeding 90% and ultra-smooth surface finish (Ra < 0.1 μm), this release film enables excellent visual inspection of coated materials while providing an ideal substrate for precision coatings. The smooth, defect-free surface ensures uniform coating application without imperfections, while the optical clarity allows for real-time quality monitoring during production. These characteristics are essential for applications requiring high surface quality, such as optical films, display components, and precision adhesive products where visual defects cannot be tolerated.
Mechanical Strength and Tension Control
The PET release film offers high tensile strength (200-300 MPa) and excellent tear resistance, providing reliable performance in high-speed web processing equipment. This mechanical robustness enables stable tension control during winding, unwinding, and processing, preventing film breakage and ensuring consistent web handling. The film's balanced stiffness and flexibility allow for smooth operation in automated production lines while maintaining flatness and preventing wrinkles or distortions that could affect coating uniformity and final product quality.
Chemical Resistance and Surface Consistency
Our PET release film exhibits excellent chemical resistance to common solvents, adhesives, and coating materials, ensuring long-term performance stability in demanding manufacturing environments. The inert surface prevents chemical interactions that could alter release properties or contaminate sensitive materials. The consistent surface energy across the entire film width ensures uniform wetting and adhesion characteristics, which is critical for achieving consistent coating thickness and quality in precision manufacturing applications such as ceramic tape casting and lithium-battery electrode production.

Frequently Asked Questions
What is the difference between DTF and PET film?
DTF (Direct to Film) refers to a printing technology that transfers designs directly onto special film for garment decoration, while PET film is a versatile polyester material used as a release liner, carrier substrate, or protective layer in various industrial applications including tape casting, adhesive production, and precision coating.
What is transparent PET film?
Transparent PET film is a clear polyethylene terephthalate material with excellent optical clarity (>90% light transmission), dimensional stability, and mechanical strength. It's widely used as a release liner, protective layer, or carrier substrate in applications requiring visual inspection, UV curing, or precise dimensional control during manufacturing processes.
What is PET film tape?
PET film tape refers to adhesive tapes that use polyester film as the backing material, offering excellent mechanical strength, temperature resistance, and dimensional stability. In contrast, PET release film is a non-adhesive carrier or liner material designed to provide controlled release properties for adhesive products, coatings, and composite materials during manufacturing.
What is a PET release film?
PET release film is a specialized polyester film coated with silicone or other release agents to provide controlled adhesion characteristics. It serves as a temporary carrier or liner that allows easy separation of adhesive products, coated materials, or molded components while protecting sensitive surfaces and maintaining dimensional stability during manufacturing processes.
How does PET release film benefit ceramic tape casting?
In ceramic tape casting, PET release film provides a smooth, non-stick surface that allows clean separation of green ceramic tapes after casting and drying. Its dimensional stability maintains tape flatness, while its heat resistance withstands drying temperatures. The film's consistent release properties ensure uniform tape quality and thickness, critical for multilayer ceramic components like MLCCs and LTCC substrates.
