Section A: Technical Advantages

Engineered for the rigorous demands of the release liner industry, the XH3110 series maximizes the efficiency of your silicone coating lines.

• Optimized Silicone Hold-Out: The high-density structure prevents silicone penetration, reducing costly chemical consumption while maintaining consistent release forces.

• Superior Die-Cutting Stability: Outstanding dimensional stability and tensile strength allow for precision kiss-cutting and rapid matrix stripping in label production.

• Consistent Caliper Profile: Manufactured with strict thickness tolerances to ensure uniform roll winding and tension control during continuous converting.

• Excellent Transparency: The glassine base's natural translucency enables accurate optical scanning and automatic label dispensing.

Section C: Targeted Applications

An essential base material for producing premium release liners:

• Self-Adhesive Labels: Barcode labels, logistics & shipping labels, and consumer product packaging labels.

• Industrial & Medical Tapes: Double-sided tapes, masking tapes, and surgical tape backings.

• Graphic Arts: Backing paper for self-adhesive vinyl and advertising decals.

• Hygiene Products: Release tapes for feminine care and adult incontinence products.

The Physics of Supercalendering: Why Density Matters

In the production of premium release liners, not all base papers are created equal. The secret to XH3110’s performance lies in our advanced Supercalendering Technology.

Standard paper consists of a loose matrix of cellulose fibers with microscopic voids. If you apply silicone to standard paper, the expensive chemical soaks deep into the fiber matrix, wasting material and creating an uneven release surface.

How Heming Paper Solves This: During manufacturing, our glassine web passes through multiple alternating steel and polymer calender nips under extreme pressure, heat, and friction. This intense mechanical process crushes the fibers, completely eliminating internal air pockets and creating a highly dense, non-porous "closed surface".

The B2B Advantage for Converters:

• Maximum Silicone Hold-Out: The silicone stays strictly on the surface of the paper rather than penetrating it. This allows coating facilities to significantly reduce their silicone coat weight (gsm) while achieving a flawless, pinhole-free release layer.

• Consistent Release Force: A uniform surface guarantees that the release force remains extremely stable, ensuring smooth matrix stripping during high-speed die-cutting of self-adhesive labels.

• Exceptional Transparency: The high-density crushing process gives our glassine its signature translucency, which is critical for accurate optical scanning in automated label dispensing machines.

Glassine Base Paper vs Kraft Paper

How to choose glassine base paper for release liners?

1. Specify Basis Weight: Confirm whether your application requires 39 gsm, 58 gsm, or up to 78 gsm for proper tensile strength.

2. Verify Smoothness Level: Ensure the factory uses advanced supercalendering to guarantee uniform silicone coating absorption.

3. Check Compliance: Demand ISO and FDA certifications if the final liner comes into contact with medical or food products.

4. Request Bulk Samples: Test the paper's mechanical stretch and transparency before placing your wholesale MOQ order.
