About this item
SKU PT1804B — 725' × 18", 4 Mil, Black.
18 in x 725 ft 4 mil black poly tubing. Makes custom-length bags on demand for odd-sized items. 4 mil film. This is the black version; a clear version is a separate listing. Shoppers also call these plastic bags or poly bags. Cut and seal custom-length bags straight off the roll.
Common questions
What size bags can I make from this 18" x 725' roll?
The roll is listed at 18" x 725'. You cut the tubing to whatever length each item needs and seal both ends, so bag length is up to you; only the layflat width is fixed. Size the width with a little slack so contents slide in without stretching the film.
What does 4 mil film mean in practice?
A mil is one-thousandth of an inch, so 4 mil film is 4/1000" thick — 4 mil film, for example, is twice the film thickness of 2 mil. Heavier film of the same material stands up to punctures and rough handling better; lighter film costs less per bag and packs tighter. This listing's material is specified as Low-Density Polyethylene (LDPE) - All Virgin.
Can a nearby size or thickness replace PT1804B?
Not as an exact replacement. Treat any different size or film weight as a different product. Before switching, match the listed dimensions and 4 mil thickness — then reorder by exact SKU PT1804B.
What equipment do I need to use this tubing?
Cut pieces are closed on both ends — most operations use an impulse or heat sealer, though tape or twist ties also work for temporary closures. Orders ship from Packrift's five US warehouse regions (Central IL, NE PA, S TX, SE GA, and W CA); delivery options and timing are shown at checkout.
