This 14 inch by 725 foot black poly tubing is manufactured from all-virgin low-density polyethylene (LDPE) at a 4 mil thickness, producing a fully opaque barrier that conceals contents from view. The roll format lets operators cut to any required length and heat seal both ends with a standard impulse sealer, eliminating the need to stock multiple pre-made bag sizes.

The 4 mil gauge delivers puncture and tear resistance suited to heavier or irregularly shaped items. The opaque black film is especially practical for light-sensitive components, proprietary parts, or any application where content concealment is a handling or security requirement — common in electronics manufacturing, automotive parts distribution, and industrial fulfillment operations.

Each roll weighs approximately 35.16 lbs and yields 725 feet of usable tubing, reducing changeover frequency on active pack lines. Impulse sealers are sold separately and required to complete the seal.
