Why choose glassine over CCK release paper for labels?

Glassine is preferred when the application requires a smoother release surface, better dimensional precision for high-speed die-cutting, or stronger barrier properties for food and pharma packaging. CCK release paper offers a broader GSM range (55–135 GSM) for general industrial release applications and is typically more economical for high-volume non-premium uses. Many label converters use both depending on the end product.

Is glassine release paper food-safe?

Glassine paper itself is widely used in food packaging applications due to its natural grease and moisture barrier properties. Food contact suitability of any specific silicone-coated grade depends on the silicone system used and the end-use scenario. For food contact applications, request a product specification sheet to confirm the grade’s suitability for your specific use.

What is glassine release paper?

Glassine is a smooth, dense, semi-transparent specialty paper produced by super-calendering wood pulp fibres until the surface is glossy and air-, water-, and grease-resistant. When silicone-coated on one or both sides, it becomes a release liner used primarily in pressure-sensitive labels, food and pharmaceutical packaging, and high-speed labelling applications.
