Material Selection Guide: Choosing the Right Substrate

Choosing the correct base material is the first step in ensuring label performance. We offer a diverse portfolio to match every adhesive type and application environment.

Substrate TypeKey CharacteristicsBest Labeling Applications
Glassine PaperHigh density, semi-transparent, excellent tensile strength.High-speed automated labeling, logistics, food & beverage.
PET Release FilmUltra-smooth, 100% transparent, moisture-proof, high dimensional stability.“Clear-on-clear” labels, cosmetics, electronics, medical applications.
CCK (Clay Coated)Exceptional flatness, heat resistance, eco-friendly.Large-format advertising, car wraps, industrial stickers.
PE Coated Paper  PE Moisture barrier, prevents curling in humid environments.DIY stickers, outdoor labels, double-sided tapes.

Targeted Industry Applications

We don’t just sell paper; we provide solutions tailored to the unique stresses of your specific market

Logistics, E-commerce & Retail

High-volume labeling requires cost-effective durability. We provide high-strength Glassine Release Paper that won't tear during high-speed thermal printing or automated sorting.

Food & Beverage Labeling

Our liners are designed to withstand moisture and cold-chain storage. We ensure that the release force remains consistent from the bottling plant to the consumer's hand, even in damp conditions.

Pharmaceutical & Healthcare

In an industry with zero tolerance for contamination, our 10,000-class cleanroom manufactured PET liners ensure no dust or microscopic defects interfere with medical tracking labels or surgical tapes.

Automotive & Electronics

For labels exposed to heat and chemicals, we provide heat-stabilized PET films and Fluorosilicone coatings that work seamlessly with aggressive industrial or silicone-based adhesives.

Solving Critical Manufacturing Pain Points

We help B2B buyers and production engineers eliminate the “invisible” problems that lead to downtime and waste

Common ProblemRoot CauseYINGFEI Solution
Web BreaksInconsistent liner thickness (caliper).±2 micron tolerance ensures consistent die-cutting strikes.
Adhesive GhostingIncomplete silicone curing (migration).100% Polymerized Coating ensures high residual adhesion strength.
Label “Flying”Release force is too light for machine speedCustomized Release Profiles (Easy to Tight) to match your line speed.
Liner CurlingMoisture imbalance in paper substrates.Double-sided PE Lamination for perfect flatness in all climates.

Technical Specifications and Customization (B2B & Wholesale)

As a direct factory, YINGFEI offers customization capabilities that trading companies cannot match. We serve wholesalers and large-scale converters worldwide.

  • Precision Slitting: Widths available from 15mm up to 1650mm.
  • Weight & Grammage: Comprehensive range from 30g to 300g.
  • Release Force Calibration: Fully adjustable from 1g to 100g+ to suit Acrylic, Hot-melt, or Rubber adhesives.

Manufacturing Excellence: The YINGFEI Advantage

Every batch of release liner undergoes rigorous testing before it leaves our factory:

  • 10,000-Class Dust-Free Cleanroom

For high-transparency PET films used in electronics and optics, cleanliness is mandatory. Our cleanroom prevents “fish-eyes” and surface contamination, ensuring a flawless adhesive finish.


  • Integrated Quality Control (QC)：

Every batch of release liner undergoes rigorous testing before it leaves our factory:

  • Release Force Testing: Verified at multiple peel speeds.
  • Residual Adhesion Strength (RAS): Ensures the silicone does not damage your adhesive.
  • Dimensional Stability: Testing for heat shrinkage and moisture expansion.

Troubleshooting & Technical FAQ

PET is superior for ultra-high-speed automated lines and “clear-on-clear” aesthetics due to its strength and smoothness. Glassine is the most cost-effective and common solution for standard paper labels and thermal printing.

This is usually caused by a release force that is too light for the label’s weight or the dispenser’s speed. We can provide a “Medium” or “Tight” release profile to solve this.

Yes. All YINGFEI products are RoHS and REACH compliant. We also offer FSC-certified paper options for brands prioritizing sustainable and ethical sourcing.
