Plasma-Treated PET Release Film: Enhanced Surface Performance for Demanding Applications

Introduction

Plasma-treated PET (polyethylene terephthalate) release film is an advanced material engineered with superior surface properties through plasma modification technology. This treatment enhances adhesion control, surface energy, and compatibility with various coatings and adhesives while maintaining the inherent strength and flexibility of PET. Ideal for high-performance industries such as electronics, medical devices, and composite manufacturing, plasma-treated PET release film ensures optimized performance in critical applications where standard films may fail.

Key Features and Benefits

1. Precise Surface Modification

Plasma treatment activates the PET surface by introducing polar functional groups (e.g., -OH, -COOH), improving wettability and bonding characteristics.

Enables tunable release properties, allowing customization for different adhesive systems (silicone, acrylic, or rubber-based).

2. Enhanced Adhesion & Coating Uniformity

Provides a clean, contaminant-free surface for superior coating adhesion, essential for high-end release liners and functional films.

Reduces coating defects such as fisheyes or delamination, improving production yield.

3. Consistent Performance Under Extreme Conditions

Maintains stability in high-temperature curing processes (up to 200°C+) and harsh chemical environments.

Resists moisture absorption, ensuring reliable performance in humid or sterile applications.

4. Eco-Friendly & Solvent-Free Process

Unlike traditional chemical priming, plasma treatment is a dry, solvent-free process, reducing environmental impact and VOC emissions.

Eliminates the need for additional primers, reducing production costs and complexity.

5. Versatile Thickness & Customization

Available in a wide range of thicknesses (12µm to 250µm) to suit different industrial needs.

Can be ombined with matte, glossy, or textured finishes for specialized applications.

PET Release Film for New Energy and Environmental Protection Industry delivers high-temperature resistance and UV-blocking properties for critical applications in solar panel backsheet lamination and lithium-ion battery separator processing, while Roll PET Release Film optimizes winding tension control and anti-static treatment to ensure defect-free continuous production in large-scale photovoltaic module assembly and eco-friendly packaging material coating lines.
