Common questions
What actually fits inside a 20" H x 12" W x 8" D gusseted bag?
The listed size is 20" H x 12" W x 8" D — 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 20" H x 12" W x 8" D, so that measurement is what your item has to fit within.
Is 1 mil the right thickness for my use?
A mil is one-thousandth of an inch, so 1 mil film is 1/1000" 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 1 Mil Low-Density Polyethylene (LDPE).
Is there a drop-in substitute for PB1378?
Not as an exact replacement. The closest sizes in this line are 15x11x18" and 30" H x 12" W x 8" D (Gusseted) (same 1 mil film), and the same 20" H x 12" W x 8" D size is also stocked in 2 mil. Before switching, match the listed dimensions, 1 mil thickness, and case count — then reorder by exact SKU PB1378.
What do I need to seal these, and what does a full order look like?
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 500 bags — roughly $0.11 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.
