Common questions
Will a boxy or bulky item fit in this 12" W x 4" Gusset x 18" H bag?
The listed size is 12" W x 4" Gusset x 18" H — 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 12" W x 4" Gusset x 18" H, 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 2 Mil Low-Density Polyethylene (LDPE).
Can I swap PB4290 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 10x4x20" and 10x6x18"; any size change alters the usable interior. Before switching, match the listed dimensions, 2 mil thickness, closure type, and pack count — then reorder by exact SKU PB4290.
Do these bags reseal, and how do they arrive?
The closure is listed as Double-Track Reclosable Zipper, so the bag closes without separate tape or heat. This listing is sold as one pack of 500 bags — roughly $0.21 per bag at the current pack 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.
