  • Highly engineered solutions that offer a wide breadth of silicone systems and release differentials to fit the many demands of the segments we serve.

In the tapes and sealant market, release liners act as a carrier and delivery system for adhesives. The liners must have the performance characteristics to withstand demanding environmental and coverting conditions, yet maintain the strength and stability to ensure end user requirements are met.


Ahlstrom’s Coated Products’ DualBak™ liners are highly engineered solutions that offer a wide breadth of silicone systems and release differentials to fit the many demands of the segments we serve. Through collaboration with our customers we develop application-specific liners that contain the functional properties that are critical to the success and delivery of the adhesive.

Attributes

Dimensional stability: DualBak™ hybrid release liners are dimensionally stable sheets with superior hygroexpansivity properties critical to many applications that endure variations in heat and humidity conditions.

Die-cut ability: Caliper-controlled release liners offer consistent density and caliper as required by end-use application.

Temperature resistance: Ahlstrom’s paper base substrates offer a higher resistance to heat than polycoated liners, allowing converters to run at higher temperatures and speeds.

Stable release: Custom release formulas provide converters with well-cured, stable release systems, critical to adhesive performance over time.

Strength: Liners offer high tear-strength to withstand the challenging conditions the liner is exposed to in specialty tape and sealant applications.

Consistent release differential: Custom designed for specific adhesives with the optimum differential to prevent side-to-side confusion.

Collaborative innovation: The Ahlstrom Coated Products team draws on its unique manufacturing capabilities, extensive technical knowledge, and expertise to collaborate with customers by providing innovative, customized solutions to the tape and sealant industry. FSC®, SFI®, PEFC® Chain of Custody certification available.
