Common questions
Will a boxy or bulky item fit in this 40x22x72" bag?
The listed size is 40x22x72" — the gusseted sides fold out so the bag can open to its listed depth and sit around blockier items. Plan for contents slightly smaller than the nominal size — the usable interior runs a bit under the listed measurement once the bag takes shape around what you load into it.
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), 4 Mil Thickness.
Can I swap PB1890 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 24x20x48" and 36x28x60"; any size change alters the usable interior. Before switching, match the listed dimensions, 4 mil thickness, and case count — then reorder by exact SKU PB1890.
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 50 bags — roughly $4.55 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.
