Manteno, Ill.-based Zip-Pak’s new Vector Resealable Matrix offers secure closure of flexible packaging without exact alignment of opposing segments and is already being used by Fairview, Ore.-based Townsend Farms Inc.

Zip-Pak bills the new technology as a way fresh produce suppliers can provide customers with “tactile and audible feedback for reassurance of complete fastening with each use,” according to a company news release. “Vector resealable matrix’s ability to mate to itself will also advance new packaging concepts that require a self-sealing closure, including Pour & Lok and Zip360.”

It’s billed to be easily incorporated into any company’s existing machinery.

Zip-Pak talked up the matrix Sept. 23-25 at Pack Expo 2013 in Las Vegas.
