Common questions
How do I know if my item fits the 12x18" size?
The listed size is 12x18". The catalog lists inside-usable dimensions of 12" x 18", so that measurement is what your item has to fit within.
What does 8 mil film mean in practice?
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 8 Mil LDPE Polyethylene.
Can I swap PB3941 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 12x15" and 13x18" (same 8 mil film), and the same 12x18" size is also stocked in 2 and 4 mil. Before switching, match the listed dimensions, 8 mil thickness, closure type, and case count — then reorder by exact SKU PB3941.
Do these bags reseal, and how do they arrive? And can I use them for food?
The closure is listed as Full-Width Track Zipper, so the bag closes without separate tape or heat. This listing is sold as one case of 250 bags — roughly $0.69 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. On food use: the film is 8 Mil LDPE Polyethylene, a material commonly used in food packaging, but food-contact compliance is certified per product lot. Check the spec sheet or contact us for documentation before direct food contact.
