High-Performance Release Liners & Films for Adhesive Tape Manufacturing
In the world of high-end tape manufacturing, the release liner is not just a “disposable carrier.” It is a precision-engineered component that ensures adhesive integrity, facilitates high-speed converting, and determines the end-user experience.
As a leading B2B manufacturer, YINGFEI (Guangzhou Yingfei Paper and Plastic Products Co., Ltd.) specializes in high-quality Release Papers and PET Release Films specifically designed for the global adhesive tape market. From industrial masking to optical-grade electronic tapes, we provide the stable release platforms that the world’s leading tape brands rely on.
Comprehensive Material Solutions for Every Tape Category
Not all tapes are created equal. We provide a diverse matrix of substrates to match your specific adhesive chemistry and application environment.
PET Release Films (Polyester)
- Best For: Electronic tapes, OCA (Optically Clear Adhesive), medical tapes, and high-clarity labels.
- Key Features: Ultra-smooth surface, extreme dimensional stability, and zero fiber contamination.
- YINGFEI Advantage: Available in Transparent, Blue, White, Matte, and Red. Our 10,000-level dust-free workshop ensures that our PET films meet optical-grade requirements for sensitive electronic components.
Glassine Release Paper
- Best For: High-speed automatic labeling, double-sided tissue tapes, and rotary die-cutting.
- Key Features: High density, transparency (for sensor detection), and excellent tensile strength.
- YINGFEI Advantage: We provide FSC-certified high-quality Glassine that withstands the rigors of high-speed rotary die-cutting without web breaks.
CCK (Clay Coated Kraft) Paper
- Best For: Carbon fiber prepreg, large-format graphics, and heat-sensitive tapes.
- Key Features: Exceptional flatness and superior temperature resistance.
- YINGFEI Advantage: Our CCK liners are engineered to resist curling even in fluctuating humidity, making them the preferred choice for industrial sheets and graphic arts.
PE Coated (Polyethylene) Release Paper
- Best For: Foam tapes (PE/EVA), automotive emblems, and double-sided tapes.
- Key Features: Moisture-proof barrier, added stiffness, and cost-effectiveness.
- YINGFEI Advantage: We offer single and double-sided PE lamination with customized grammage (30g-300g) to match the weight and thickness of your tape.
Solving the Technical Pain Points of Tape Converters
We understand the frustrations of tape manufacturers. Our R&D team has developed solutions for the most common industry failures
Avoiding "Lock-Up" (Silicone Migration)
The Problem: Silicone migrates into the adhesive, causing the tape to lose its "tack" or become impossible to peel after storage.
The YINGFEI Solution: We use advanced curing technology to ensure a high Residual Adhesion Rate (SAS >90%). Our silicone is chemically bonded to the substrate, ensuring it stays on the liner, not on your tape.
Precise Differential Release for Double-Sided Tapes
The Problem: When unwinding double-sided tape, the wrong side peels off, leading to production jams.
The YINGFEI Solution: We specialize in Differential Release Liners. We can engineer Side A with a "Easy Release" (e.g., 5g) and Side B with a "Tight Release" (e.g., 40g), ensuring a perfect, predictable unwind every time.
Surface Energy & Adhesive Wetting
The Problem: Adhesive "beading" or uneven coating on the liner.
The YINGFEI Solution: We provide customized surface treatments (Corona treatment) to ensure the perfect surface energy, allowing your adhesive to wet out smoothly for a flawless coating.

Why Partner with YINGFEI? (Our Manufacturing Power)
As a professional manufacturer and wholesaler, we offer more than just a product; we offer a supply chain advantage.
Custom Slitting & Widths
Our high-speed precision slitting machines can cut rolls from 15mm to 1650mm wide.
Custom Printing
Increase your brand value by printing logos, grid lines, or instructions on the back of your liners.
Scale & Capacity
With multiple coating lines (Silicone, PE, Printing), we handle high-volume wholesale orders with short lead times.
Global Export Standards
We understand the logistics of international trade. Our packaging is designed for sea freight, ensuring your rolls arrive without moisture damage or core crushing.
Fluorine Release Liners for Silicone Tapes
One of our flagship products is the Fluorine (Fluoro-silicone) Release Film.
Standard silicone liners will bond permanently to silicone adhesives. If you are manufacturing Green Polyester Tape, Polyimide (Kapton) Tape, or Silicone Foam, you require our specialized Fluorine-coated PET. We are one of the few factories in China capable of producing stable, high-performance fluorine liners that provide a smooth, easy release for silicone-based glues.
Quality Control: The YINGFEI Standard
Every batch of our release material undergoes a rigorous 5-step testing process
Release Force Testing
Residual Adhesion Test
Aging Test
Surface Roughness Analysis
Thickness Uniformity
Frequently Asked Questions (FAQ)
Yes. We have universal silicone formulations designed to provide stable release for a wide range of pressure-sensitive adhesives (PSA).
While we are a high-capacity factory, we offer flexible Minimum Order Quantities (MOQ) for specific materials to help our partners grow.
We can provide Anti-Static (ESD) PET Release Films which are crucial for the electronics industry to prevent damage to sensitive components during the peeling process.
