Charmetack CCK (Clay Coated Kraft) Release Paper is a high-performance silicone liner known for its exceptional dimensional stability and high-temperature resistance. Unlike PE-coated papers, CCK paper uses a specialized clay coating to seal the paper surface, making it the preferred choice for processes involving heat curing or high-precision die-cutting.
- High Temperature Stability — Capable of withstanding high-temperature environments (such as carbon fiber curing or hot-melt coating) without the wrinkling or melting associated with PE liners.
- Superior Lay-Flat Properties — The clay coating acts as a moisture barrier, ensuring the paper remains perfectly flat during storage and converting, preventing edge-curl issues.
- Eco-Friendly & Recyclable — Being plastic-free (No PE layer), CCK paper is more environmentally friendly and easier to recycle, helping you meet sustainability goals.
- Excellent Silicone Anchorage — The smooth clay surface ensures a uniform silicone distribution, resulting in a stable and consistent release force.
