Common questions
How much usable room does the 4x12" size really have?
The listed size is 4x12". Plan for contents slightly smaller than the nominal size — the usable interior runs a bit under the listed measurement once the bag takes shape around what you load into it.
What does 4 mil film mean in practice?
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 PB3718?
Not as an exact replacement. The closest sizes in this line are 4x10" and 4x14" (same 4 mil film), and the same 4x12" 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 PB3718.
Do these bags reseal, and how do they arrive? And can I use them for food?
The closure is listed as Single-Track Zipper (Full-Width), so the bag closes without separate tape or heat. This listing is sold as one case of 1,000 bags — roughly $0.083 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 4 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.
