Single Side PE Coated Release Paper (PCK)

Single Side PE Coated Release Paper (PCK Liner)

Charmetack Single Side PE Coated Release Paper (PCK) is the versatile workhorse for the label and tape industry. Featuring a Polyethylene (PE) coating on the functional side and raw Kraft paper on the reverse, it offers the perfect balance of surface smoothness and backside printability. It is widely used where moisture protection is needed only on the adhesive side.

Printable Backside — The uncoated reverse side allows for easy printing of logos, barcodes, grids, or instructions (ideal for courier labels and medical tapes).
Superior Silicone Anchorage — The PE layer creates a non-porous barrier, preventing silicone penetration and ensuring a consistent, stable release force.
Clean Die-Cutting — The PE coating adds structural integrity to the paper, minimizing fiber tear and dust during high-speed rotary die-cutting.

product description

The Cost-Effective Standard for Labels and Tapes.

Charmetack’s Single Side PE Coated Paper (PCK) combines the strength of Kraft paper with the surface smoothness of a Polyethylene (PE) coating. The PE layer fills the microscopic pores of the paper, creating a glass-like surface that requires less silicone while delivering a more consistent release force than standard Clay Coated Kraft (CCK).

Unlike double-sided liners, the backside remains uncoated raw paper, making it perfect for flexographic printing (logos, instructions, or grids).

Why Choose Our PCK Liner?

Backside Printability: The non-coated reverse side is suitable for writing or printing branding information, making it ideal for courier labels and instructional tapes.
Superior Silicone Hold-out: The PE barrier prevents silicone from soaking into the paper fibers, ensuring a 100% effective cure and preventing "lock-up" over time.
Clean Die-Cutting: The plastic coating acts as a cushion during die-cutting, allowing for "Kiss-Cutting" without dusting or fiber tear.
Moisture Resistance (Front): The PE side is waterproof, protecting the adhesive layer from humidity ingress.

FAQ: Single Side PCK

Q: What is the difference between PCK and CCK?

PCK (Poly Coated Kraft) uses a plastic PE layer to smooth the surface, offering better moisture resistance and smoother release. CCK (Clay Coated Kraft) uses a clay coating, which is cheaper and better for high-temperature applications but less moisture-resistant.
