Common questions
What actually fits inside a 7x8" bag?
The listed size is 7x8". 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 Low-Density Polyethylene (LDPE), 4 Mil Thickness.
Is there a drop-in substitute for PB3749?
Not as an exact replacement. The closest sizes in this line are 6x8" and 7x9" (same 4 mil film), and the same 7x8" size is also stocked in 6 mil. Before switching, match the listed dimensions, 4 mil thickness, closure type, and case count — then reorder by exact SKU PB3749.
How does the closure work, and what does a full order look like? 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 $0.097 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 Low-Density Polyethylene (LDPE), 4 Mil Thickness, a material commonly used in food packaging, and the manufacturer spec sheet for this item lists "Compliance: FDA & USDA Approved". Food-contact compliance is still certified per product lot, so check the spec sheet or contact us for lot documentation before direct food contact.
