Coming in a variety of styles and sizes, our Poly Tubing is efficiently manufactured and wound on 3" cores. Core plugs have 1" diameter holes. This heat sealable poly tubing is available in over 100 stock sizes. When you're not sure of the bag size, or if you have different sized items, you can use poly tubing and a heat sealer to make your own length bags. We have clear tubing ranging from 1.5 MIL to 6 MIL (thickness) and widths from 2 to 48 inches.
