Common questions
How do I know if my item fits the 7x9" size?
The listed size is 7x9". The catalog lists inside-usable dimensions of 7" W x 9" H, so that measurement is what your item has to fit within.
Is 4 mil the right thickness for my use?
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 4 Mil LDPE Polyethylene.
Can a nearby size or thickness replace PB3751?
Not as an exact replacement. The closest sizes in this line are 7x8" and 7x10" (same 4 mil film), and the same 7x9" size is also stocked in 2 mil. Before switching, match the listed dimensions, 4 mil thickness, closure type, and case count — then reorder by exact SKU PB3751.
Do these bags reseal, and how do they arrive?
The closure is listed as Full-Width Single-Track Zipper, so the bag closes without separate tape or heat. This listing is sold as one case of 1,000 bags — roughly $0.088 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.
