The Gold Standard for High-Speed Automatic Labeling.
Charmetack’s **Glassine Silicone Release Paper** is a super-calendered, high-density liner designed for the most demanding pressure-sensitive applications.
Engineered with an ultra-smooth surface and uniform silicone coating, it ensures **precise die-cutting** and **jam-free dispensing** on high-speed labeling lines.
Whether you are producing variable information labels (barcode), medical tapes, or logistics stickers, our glassine liner provides the optimal balance of **transparency** and **tensile strength**.
Why Choose Charmetack Glassine Liner?
- Superior Die-Cutting: High fiber density prevents the liner from breaking during rotary die-cutting, allowing for deeper cuts without snapping ("anvil marks").
- Optical Transparency: Excellent light transmission makes it perfect for optical sensors on automatic labeling machines (detecting gaps between labels).
- Consistent Release Force: We offer customizable release values (Light/Medium/Heavy) that remain stable over time, preventing "label drop-off" or "hard peel" issues.
- Dimensional Stability: Low moisture expansion means the paper won't curl or wrinkle in humid environments, keeping your labels flat.

FAQ: Glassine Release Paper
Q: What is the difference between Glassine and CCK paper?
Glassine is super-calendered, making it semi-transparent, denser, and smoother, which is better for precise die-cutting. CCK (Clay Coated Kraft) is opaque and bulkier, better for sheet-fed laser printing labels (like Amazon shipping labels).
Q: Why is transparency important for glassine?
Transparency allows automatic labeling machines' optical sensors to "see" the gap between labels, ensuring the machine stops and starts at the exact right position.
Q: Can you offer double-sided silicone coating?
Yes. We supply double-sided (S2S) glassine release paper, commonly used for manufacturing double-sided adhesive tapes and foams.
