Common questions
How much usable room does the 9x12" size really have?
The listed size is 9x12". The catalog lists inside-usable dimensions of 9 x 12 inches, so that measurement is what your item has to fit within.
Is 8 mil the right thickness for my use?
A mil is one-thousandth of an inch, so 8 mil film is 8/1000" 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 LDPE Polyethylene (8 Mil).
Can I swap PB3918 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 8x12" and 10x12" (same 8 mil film), and the same 9x12" size is also stocked in 1.6 and 2 mil. Before switching, match the listed dimensions, 8 mil thickness, closure type, and case count — then reorder by exact SKU PB3918.
How do these bags close, and how are they shipped?
The closure is listed as Full-Width Track Zipper (Reclosable), so the bag closes without separate tape or heat. This listing is sold as one case of 500 bags — roughly $0.36 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.
