Why choose CCK over glassine release paper?

CCK release paper offers a broader GSM range (55–135 GSM) and is typically more economical for general-purpose and high-volume industrial release applications. Glassine is preferred when the application needs a smoother, more transparent surface or stronger grease and moisture barrier properties, such as food or pharmaceutical packaging. Many converters use both depending on the end product.

What is CCK release paper?

CCK (clay-coated kraft) release paper is a silicone-coated release liner made from clay-coated kraft base paper. It offers a smooth, uniform surface and consistent silicone release performance, making it a widely used liner for self-adhesive labels, tapes, and industrial applications.

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.
