Yellow Glassine Paper High Visibility Color for Product Differentiation and Label Liners
Designed for applications requiring visual distinction, yellow glassine paper combines all technical properties of standard glassine – density ≥1.00 g/cm³, smoothness ≥600s, oil absorption ≤1.1 g/m² – with a vibrant, uniform yellow tone. The color is integrated throughout the paper (not just surface-coated), ensuring no rub-off or fading during coating, die-cutting, or dispensing. Ideal for color-coded release liners, warning labels, medical device packaging, and high-visibility interleaving. Made from 100% bleached sulfate wood pulp, free of fluorescent agents, and fully recyclable.

| Whiteness (base) | % | Not applicable (colored) |
| Color Match | ΔE | ≤2.5 (Pantone or custom) |
| Moisture | % | 4.5-7.0 |
Food-grade, non-migrating yellow dye (or pigment) is added during pulping or at the size press stage. The base pulp – 100% bleached sulfate softwood and hardwood – is refined to high fibrillation (beating degree 22-30°SR). AKD sizing (1.5-2.0%) and cationic starch (0.8-1.0%) are blended. The colored slurry is formed on a fourdrinier wire, pressed, and pre-dried. PVA surface sizing (4% concentration, 15-20 kg/ton) seals the surface. Supercalendering with 10-12 alternating steel and fiber rolls at 80-120°C and 300-500 kN/m linear pressure produces density ≥1.00 g/cm³ and a mirror-smooth finish on both sides. The color is uniform throughout the cross-section, resistant to silicone coating solvents, and will not transfer to adhesive or labels. Moisture balanced for 24-48 hours, then slit to customer widths.
- Color-Coded Release Liners – Yellow distinguishes specific adhesive formulations or product lines; reduces assembly errors in high-volume converting.
- Warning & Caution Labels – High-visibility yellow backing for safety labels on industrial equipment or hazardous materials.
- Medical Device Packaging – Yellow liner for sterile barrier systems; easy to see if liner is missing or misaligned.
- Electronic Die-Cutting – Yellow glassine serves as a visual contrast base when cutting transparent or light-colored adhesive films.
- Food Packaging – Allergen-warning release paper (e.g., yellow for nut-containing products) in bakery or confectionery lines.
- Craft & Stationery – Bright yellow interleaving for sticker sheets, washi tape release, and kid-friendly craft projects.
Why Choose This Paper – Yellow glassine combines high-performance release liner properties with instant visual recognition, helping streamline production, improve quality control, and enhance brand or safety messaging without any functional compromise.
