Food-grade PET Release Film, Silicone-coated PET Release Film, and Extrusion-coated PET Release Film: High-Performance Solutions for Modern Manufacturing  

This innovative range of release films offers superior performance across diverse industrial applications, with a focus on safety, sustainability, and precision. Whether you're working in food packaging, pharmaceuticals, or advanced composite manufacturing, our product line delivers consistent results backed by rigorous quality standards. The inclusion of biodegradable PET release film options reflects our commitment to environmentally responsible materials without compromising functionality.

Key Features  

Our Food-grade PET Release Film is manufactured using non-toxic resins compliant with FDA and EU regulations, ensuring safe contact with consumable products. The Silicone-coated PET Release Film provides excellent adhesion control—ideal for laminating, printing, and coating processes where surface integrity matters. Meanwhile, the Extrusion-coated PET Release Film combines mechanical strength with uniform thickness, making it perfect for high-speed automated systems. All variants are engineered for low residue transfer, thermal stability up to 180°C, and resistance to oils, solvents, and UV exposure.

Detailed Description  

Each film type leverages proprietary coating technologies tailored to specific needs. The silicone-coated version uses a cross-linked siloxane layer that minimizes tackiness while maintaining clean release properties—critical for delicate substrates like medical tapes or flexible electronics. The extrusion-coated variant employs coextrusion techniques to bond multiple polymer layers, enhancing tear resistance and dimensional stability under stress. The biodegradable PET release film, formulated from bio-based polyethylene terephthalate, breaks down efficiently in industrial composting environments within 6–12 months, aligning with circular economy goals. These films are available in various widths (from 300mm to 2000mm), thicknesses (12μm to 75μm), and finishes (matte, glossy, or embossed), allowing customization for different machinery and end-use requirements.

Applications  

Ideal for use in food processing lines where direct contact with edible goods must be avoided; also widely adopted in the production of pressure-sensitive adhesives, tape manufacturing, and prepreg composites for aerospace components. In the automotive sector, these films serve as release liners for structural bonding agents. Additionally, they support sustainable packaging initiatives by replacing conventional plastic liners with compostable alternatives that reduce landfill waste. Their compatibility with both manual and robotic handling systems makes them versatile across global supply chains—from North America to Europe and Oceania.

Customer Feedback  

Users consistently highlight improved process efficiency and reduced downtime due to fewer defects caused by sticking or tearing. One manufacturer noted a 40% decrease in rework rates after switching to our silicone-coated PET release film in their label production line. Another praised the biodegradable option for meeting corporate ESG targets without sacrificing performance. Many reviewers emphasize how the films’ consistent thickness tolerance (±3%) enhances print accuracy and reduces material waste during die-cutting operations.

Frequently Asked Questions  

What distinguishes food-grade PET release film from standard versions? It meets international food safety certifications, such as 21 CFR 177.1520 and EN 1500, ensuring no migration of harmful substances into packaged foods.  

How does the extrusion-coated variant improve productivity? Its robust structure prevents web breaks during high-speed winding, minimizing machine stoppages and boosting throughput.  

Is the biodegradable PET release film suitable for all climates? Yes—it maintains performance across temperature ranges from -20°C to +80°C, though storage recommendations vary based on humidity levels.  

Can I request custom sizes or coatings? Custom roll lengths, widths, and functional coatings (e.g., anti-static or conductive) are available upon request for bulk orders.  

Do these films comply with RoHS and REACH standards? Absolutely—they contain no restricted substances and are fully traceable through batch documentation.

PET Release Film for New Energy and Environmental Protection Industry delivers thermal stability and chemical resistance for high-performance applications in perovskite solar cell encapsulation and hydrogen fuel cell membrane electrode assembly, while Extrusion-coated PET Release Film integrates multi-layer co-extrusion technology with adhesive anchoring properties to enhance process efficiency in large-scale wind turbine blade composite molding and biodegradable packaging film lamination.
