Poly Pak Plastics is a custom wholesale manufacturer of plastic tubing. We extrude and convert 100% virgin, high clarity polyethylene film into whatever size poly tubing you need. Because it's made from virgin polyethylene materials, tubing is FDA approved for food and medical handling. Bags are clear though custom coloring is available to suit your specific application. Poly tubing is heat sealable and thermal sealers and other bag closers can be ordered through Poly Pak Plastics.
