Product Introduction
Products Description
Glassine Liner Roll Paper is a 58gsm supercalendered glassine paper with a double-sided silicone release coating - engineered as the backing liner for self-adhesive labels, pressure-sensitive tapes, die-cut stickers, and industrial adhesive products.
The dense supercalendered structure delivers consistent caliper (0.050 ±0.01 mm), high tensile strength (79N MD / 69N CD), and a smooth, flat surface that feeds reliably through high-speed automatic labeling, die-cutting, and matrix-stripping equipment. Two release force options are available: easy release (10–15 g/in) for standard label applications and tight release (30–40 g/in) for demanding converting processes where premature liner separation must be prevented.
Residual adhesion of ≥90% (easy release) or ≥85% (tight release) ensures the silicone coating does not transfer to the adhesive - preserving bond performance in the finished label or tape product. Supplied in rolls with optional photocell registration markings for automated dispensing systems.
Product Features
Precision Silicone Release Coating - Two Force Levels
Double-sided silicone coating with selectable release force to match your application:
Easy Release (10–15 g/in): For standard label converting and consumer sticker products where end users expect effortless liner peel
Tight Release (30–40 g/in): For high-speed die-cutting, small-part labels, and automated dispensing where the liner must stay in place through aggressive converting
Consistent Caliper and High Tensile Strength
At 58 ±2 gsm with 0.050 mm thickness, the supercalendered glassine structure delivers uniform caliper across the full roll width. Tensile strength of 79N (MD) and 69N (CD) resists tearing during high-speed matrix stripping and die-cutting - reducing web breaks and production downtime.
High Residual Adhesion - No Silicone Transfer
Residual adhesion of ≥90% (easy release) and ≥85% (tight release) confirms the silicone coating is fully cured and cross-linked. The adhesive layer on your label or tape retains its bonding performance - no release force degradation over time, no silicone contamination affecting end-use adhesion.
Smooth, Flat Surface for Reliable Converting
The supercalendered finish provides a mirror-smooth surface that tracks true through coating heads, printing stations, die-cutting cylinders, and auto-dispensing sensors. No surface irregularities that cause misfeeds or registration drift.
Semi-Transparent with Photocell Compatibility
Natural glassine translucency enables visual inspection of adhesive coverage during production. Available with printed photocell registration marks for automated labeling machines and dispensing systems.

Release Grade Selection Guide
| Application | Recommended Grade | Reason |
|---|---|---|
| Standard paper labels (A4 sheet, roll labels) | Easy (10–15 g/in) | End-user peel comfort is priority |
| Die-cut stickers and decals | Easy or Tight | Depends on part size - small parts may need tight |
| Small-part labels (electronics, cosmetics) | Tight (30–40 g/in) | Prevents premature liner lift during die-cutting |
| High-speed auto-dispensing | Tight (30–40 g/in) | Liner must remain flat through the dispensing head |
| Double-sided tape liner | Tight (30–40 g/in) | Liner removed during manufacturing, not by end user |
| Industrial adhesive transfer tape | Tight (30–40 g/in) | Aggressive adhesives require higher release force |
| Matrix stripping (waste removal) | Either grade | Tensile strength is the key factor, not rele |
Applications
Self-Adhesive Label Manufacturing
The primary application - glassine liner serves as the backing paper for pressure-sensitive labels used in logistics, retail, food packaging, and industrial identification. Die-cut, matrix-stripped, and slit into finished rolls or sheets.
Die-Cut Sticker & Decal Production
Release liner for custom-shaped kiss-cut stickers, decals, and promotional labels. The smooth glassine surface supports clean die-cutting to the liner without cutting through - essential for sticker sheets and multi-part decals.
Pressure-Sensitive Tape Liner
Backing liner for double-sided adhesive tapes, foam mounting tapes, and transfer adhesives. The tight-release grade ensures the liner stays in place during slitting and converting, then releases cleanly during application.
Automated Label Dispensing
Liner rolls with printed photocell registration marks for use in automatic label applicators, print-and-apply systems, and high-speed packaging lines. Consistent caliper and flatness ensure reliable sensor detection and label placement.
Industrial & Specialty Adhesive Products
Release liner for medical dressings, EMI shielding tapes, gasket adhesives, and specialty bonding films where consistent release performance and zero silicone transfer are critical requirements.

FAQ
Q: What is the difference between the two release force options? A: Easy release (10–15 g/in) is for applications where the end user peels the liner by hand - standard labels, sticker sheets, consumer products. Tight release (30–40 g/in) is for high-speed converting, small-part die-cutting, and automated dispensing where the liner must not separate prematurely. See the Selection Guide table above for application-specific recommendations.
Q: What does "residual adhesion" mean and why does it matter? A: Residual adhesion measures how much of the adhesive's original bond strength remains after the silicone liner is peeled away. ≥90% means the silicone coating is fully cured and does not transfer to the adhesive - your label or tape will stick as designed. Lower residual adhesion indicates silicone contamination that weakens the adhesive.
Q: Can you supply this liner with photocell registration marks? A: Yes. Printed photocell marks for automatic dispensing and labeling machines are available. Provide your mark specifications (spacing, size, color) when ordering.
Q: What roll widths and lengths are available? A: Fully customizable. Standard roll widths are produced to your specification. Provide your required width, length, and core size for a quotation.
Q: What is the minimum order quantity? A: MOQ depends on roll specifications. Contact us with your requirements for a tailored quotation. Sample rolls available for evaluation.
Q: What is your typical lead time? A: Standard orders are processed within 7–10 working days. Larger volumes or custom specifications may require additional time - confirmed at order placement. Tracking information provided upon shipment.
Q: Can you produce glassine liner in other colors (yellow, blue, white)? A: Yes. In addition to natural semi-transparent glassine, we supply yellow, blue, and white glassine liner rolls. See our related products below.
Q: Which release grade should I choose for small die-cut labels (under 10 mm)? A: Tight release (30–40 g/in) is strongly recommended for small-part labels. With easy release, the liner may lift during die-cutting and matrix stripping, causing labels to detach prematurely.
