Poly tubing gives you the flexibility to create custom-length bags on demand — no inventory of pre-cut sizes needed. Unroll, cut to the exact length required, and seal both ends to wrap machined parts, knife sets, long hardware, produce bundles, and any elongated item that doesn’t fit a standard bag dimension. At 4 mil, this tubing resists puncture from sharp edges, threaded ends, and heavy components that tear through 1–2 mil tubing. The 7 in flat width opens to approximately 14 in circumference, accommodating a wide range of part diameters and widths. Wound on a 3 in core with a 1 in diameter plug for use with standard roll dispensers. Made from 100% virgin LDPE resin meeting FDA/USDA specifications.

Frequently Asked Questions

How do I use poly tubing to make a bag?

Cut the tubing to the desired length, then seal or tie one end before inserting the product. Close the open end with a heat sealer, cable tie, tape, or staple. The result is a custom bag exactly sized for your item — eliminating wasted material and overhang from pre-made bags.

What diameter items fit in 7 in tubing?

At 7 in flat (14 in circumference), the tubing comfortably wraps items up to approximately 4.5 in in diameter — such as 4 in pipe fittings, wrapped knife sets, produce bundles, or thick rolled materials.

Is 4 mil tubing compatible with impulse heat sealers?

Yes. Most commercial and industrial impulse heat sealers handle up to 6 mil LDPE. Standard jaw settings for 4 mil tubing produce a clean, strong seal without burn-through or gaps.
