50μm PE Release Film

 

Low-Temperature Resistant PE Release Film, Moisture-Resistant PE Release Film, UV-Resistant PE Release Film & High-Temperature Resistant PE Release Film – Premium Protective Solutions for Industrial and Specialty Applications

 

This advanced polyethylene release film series is engineered to meet the rigorous demands of modern manufacturing environments where thermal stability, moisture barrier performance, and long-term durability are critical. Whether you're working in aerospace composites, automotive laminates, or high-performance adhesives, these films provide superior protection during processing, storage, and transport. Each variant—low-temperature resistant, moisture-resistant, UV-resistant, and high-temperature resistant—is crafted using precision extrusion techniques and proprietary polymer blends to ensure consistent release properties across a wide range of conditions.

 

Key Features:

- Exceptional peel strength control with minimal residue on substrates  

- Enhanced dimensional stability under extreme temperatures (from -40°C to +150°C)  

- Superior resistance to humidity ingress, preventing delamination in humid climates  

- UV-stabilized formulations that prevent embrittlement and yellowing over time  

- Chemically inert surface ideal for contact with sensitive coatings, resins, and pressure-sensitive adhesives  

 

Detailed Description: High-temperature Resistant PE Film

The Low-Temperature Resistant PE Release Film maintains flexibility and integrity even at sub-zero temperatures, making it indispensable for cold-process applications such as cryogenic packaging or winter outdoor bonding operations. Its unique molecular structure allows for easy unwinding without cracking—a crucial advantage when handling delicate materials like carbon fiber prepregs or medical bandages. The Moisture-Resistant PE Release Film incorporates hydrophobic additives that significantly reduce water vapor transmission rates, ensuring product integrity in high-humidity environments such as tropical warehouses or marine-grade lamination processes. For outdoor applications, the UV-Resistant PE Release Film features titanium dioxide and hindered amine light stabilizers (HALS), which absorb and dissipate ultraviolet radiation—protecting both the film and the underlying material from degradation caused by prolonged sun exposure. Finally, the High-Temperature Resistant PE Release Film utilizes cross-linked polyethylene technology, offering excellent heat deflection temperature and maintaining uniform release behavior up to 150°C, ideal for autoclave curing, hot stamping, or industrial oven processing.

 

These films are widely used in composite manufacturing, electronics assembly, graphic arts, construction sealants, and specialty labeling industries. They serve as sacrificial layers in multi-layer systems where clean separation is essential—for example, between adhesive tapes and backing paper, or between cured resin layers in pre-preg layups. Their compatibility with solvent-based, water-based, and hot-melt adhesives makes them versatile across global supply chains.

 

Customer Testimonials: Moisture-resistant PE Release Film

“The moisture-resistant film solved our issue with blistering in humid regions. It’s now part of our standard packaging protocol for export orders.” — Quality Control Manager, Australia  

“Even at -35°C, the low-temp film didn’t crack during shipment from Finland to Sweden. Our production line runs smoother than ever.” — Production Supervisor, Canada  

 

Frequently Asked Questions:

What makes this PE release film different from standard versions?  

Unlike generic release liners, these films are formulated with specific additives tailored to environmental challenges—thermal stress, moisture penetration, or UV exposure—ensuring reliable performance beyond basic release functionality.

 

Can I use the high-temperature resistant film in an autoclave?  

Yes, it's specifically designed for temperatures up to 150°C and maintains consistent release properties under pressure and heat, commonly found in autoclave curing cycles for composites.

 

Is there any risk of contamination to the adhesive layer?  

No—these films undergo rigorous cleaning and surface treatment processes to minimize extractables, ensuring zero transfer of residues or contaminants to sensitive surfaces.

Are they recyclable?  

While not all variants are currently recyclable due to additive content, we are actively developing eco-friendly alternatives aligned with EU REACH and RoHS compliance standards.
