Griff Network patents release liner technology

The Griff Network has been awarded a patent for its Grip N Strip technology, a split-release liner.

Although initially developed for self-adhered roofing membranes, Grip N Strip has potential across numerous pressure-sensitive adhesive applications, including labels, waterproofing membranes, flashing products, tapes, building envelope materials, vehicle wraps, graphics and other adhesive-backed products.

The newly patented technology introduces an integrally formed folded pull tab within a split-release liner, allowing installers to quickly locate, grip and remove the second release liner without the frustration commonly associated with traditional split-liner systems. By eliminating the need for additional pull strips or separate components, Grip N Strip simplifies manufacturing while delivering a superior installation experience in the field.

The patent covers a release liner configuration that incorporates a folded pull tab into the liner itself, improving accessibility and reducing the likelihood of liner tearing or difficulty removing it during installation.

'Grip N Strip was developed with one goal in mind: to make installation easier for contractors,' said Alex Phinn, company president. 'By integrating the pull tab directly into the release liner, we've created a solution that helps installers work faster, reduces frustration on the job site, and improves the overall application process.'

Traditional split release liners can be difficult to separate, particularly when installers are wearing gloves or working in demanding outdoor conditions. Grip N Strip addresses this challenge by incorporating a folded pull tab that naturally presents itself for easy gripping after the first liner section is removed. The design enables installers to remove the second liner quickly while maintaining accurate membrane placement.

In addition to improving installation, the patented design streamlines manufacturing by eliminating the need for separate pull strips or added components traditionally used to facilitate release liner removal. The result is a cost-effective product that benefits both manufacturers and contractors.

In addition to the manufactured membranes, the patented release liner folding process is available for licensing.
