Common questions
How should I judge fit for the 18x18x40" size?
The listed size is 18x18x40" — the gusseted sides fold out so the bag can open to its listed depth and sit around blockier items. The catalog lists inside-usable dimensions of 40" height x 18" width x 18" gusseted depth, so that measurement is what your item has to fit within.
What does 2 mil film mean in practice?
A mil is one-thousandth of an inch, so 2 mil film is 2/1000" 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 LDPE (Low-Density Polyethylene), 2 Mil thickness.
Can a nearby size or thickness replace PB1637?
Not as an exact replacement. The closest sizes in this line are 18" W x 16" D x 40" H and 20x18x36"; any size change alters the usable interior. Before switching, match the listed dimensions, 2 mil thickness, and case count — then reorder by exact SKU PB1637.
How do I close these bags, and how do they ship?
These are open-top bags — close them with a heat sealer, bag tape, twist ties, or staples, whichever fits your workflow. This listing is sold as one case of 250 bags — roughly $0.69 per bag at the current case price (confirm the live price before ordering). 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.
