Embossed Release Paper (Air Egress Liner) | Bubble-Free Car Wrap Material

Embossed (Air Groove) Release Paper

Charmetack Embossed (Air Groove) Release Paper is the critical component for manufacturing "Bubble-Free" self-adhesive vinyls. By impressing a precise micro-structure (Grid or Diamond pattern) into the poly-coated surface, this liner creates air channels in the adhesive layer, allowing trapped air to escape easily during application. It is the industry standard for Car Wraps and Large Format Graphics.

Air Egress Technology — Enables installers to smooth out bubbles instantly with a squeegee, significantly reducing application time and labor costs.
Deep & Stable Embossing — High-GSM base paper with premium PE coating ensures the texture depth (15μm-40μm) remains distinct even after adhesive lamination.
Pattern Options — Available in Diamond (X-Shape) for superior air flow or Cube (Grid) for standard architectural films.

product description

The Solution for Bubble-Free Lamination and Application.

Charmetack’s Embossed (Air Groove) Release Paper is engineered with precise micro-structured patterns pressed into the PE coating. These patterns transfer a negative texture to the adhesive surface, creating physical "air channels" that allow trapped air to escape during application.

Combined with our uniform silicone coating technology, this liner delivers consistent release performance and high dimensional stability, making it the industry standard for Car Wraps, Air-Free Vinyls, and high-performance industrial tapes.

Key Features & Benefits

Excellent Air Exhaust: The embossed grooves effectively eliminate bubbles during manual application (e.g., vehicle wrapping) or industrial lamination.
Uniform Silicone Coverage: Specialized coating techniques ensure silicone covers both the "peaks" and "valleys" of the embossing, preventing adhesive lock-up.
High Stiffness: The PE-coated base (up to 250gsm) provides the rigidity needed for stable die-cutting and high-speed automatic dispensing.
Custom Release Profiles: We can tune the release force from Ultra-Light (1g) for easy peel to Super-Heavy (300g+) for differential release tapes.
