Polyethylene Roll Bag Cutter and GuideWhat is this thing?Use this to make cutting poly bags on a roll easier. The cutter uses a cutterharvested from a roll of Reynolds plastic wrap, and the guide is designed to helpfeed the poly bags for 4" wide tubing (example: https://www.uline.com/Product/Detail/S-1143/Poly-Tubing/4-Mil-Poly-Tubing-Roll-4-x-1500).Both the cutter and tape are designed for a piece of magnetic tape to beput into the bottom of each to hold them in place on a metal surface.Parts neededCutter and Guide1/2" wide magnetic tape (example: https://www.amazon.com/gp/product/B078SVG2CC/)Cutter onlyCutter harvested from a box of Reynolds Plastic Wrap (https://www.target.com/p/reynolds-kitchens-quick-cut-plastic-wrap-225-sq-ft/-/A-52994085)Assembly InstructionsCutterCut magnetic tape to length, press into bottom recess.
