Common questions
What actually fits inside a 10x4x20" gusseted bag?
The listed size is 10x4x20" — 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 10" W x 4" D x 20" H, so that measurement is what your item has to fit within.
How does 1 mil compare with lighter or heavier film?
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).
Can I swap PB1388 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 8x4x21" and 10" W x 6" Gusset x 20" H (same 1 mil film), and the same 10x4x20" size is also stocked in 2 and 3 mil. Before switching, match the listed dimensions, 1 mil thickness, closure type, and case count — then reorder by exact SKU PB1388.
Do these bags reseal, and how do they arrive?
The closure is listed as Twist Ties, Bag Tape, or Impulse Sealers (sold separately), so the bag closes without separate tape or heat. This listing is sold as one case of 1,000 bags — roughly $0.073 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.
