INNO-LOK® Zipper

INNO-LOK zipper for packaging

Add re-closable INNO-LOK® Zipper to your EXISTING pillow package.

Polymer Packaging is the leading converter of the INNO-LOK pre-applied zipper for use on vertical form-fill-seal (VFFS) equipment.

With the INNO-LOK Zipper, we apply a pre-zippered fastener transversely to your printed film web that runs on your existing VFFS equipment. This patented, user-friendly option can be added quickly to for minimal cost. The INNO-LOK alternative can convert your existing non-zippered products in form-fill-seal roll stock with recloseable zipper packaging in six weeks or less.

The INNO-LOK runs on all existing machines including Viking-Masek, Bosch, Triangle, Sandiacre, Hayssen, Matrix, Doboy, and Kliklok-Woodman and Rovema, to name a few. Processing on a VFFS machine requires slight modification for clearance of zipper between the forming collar and fill tube.

In addition to the multitude of frozen food and dry food applications in which INNO-LOK excels, PPI specializes in hermetic packaging for the fresh cut produce industry. This in conjunction with our Bag Top version accommodates nearly any front panel pre-applied zipper application.
