Common questions
How much usable room does the 9x12" size really have?
The listed size is 9x12". 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.
How does 4 mil compare with lighter or heavier film?
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 (Low-Density Polyethylene).
Can a nearby size or thickness replace PB3765RP100?
Not as an exact replacement. The closest sizes in this line are 7x12" and 10x12" (same 4 mil film), and the same 9x12" size is also stocked in 1.6 and 2 mil. Before switching, match the listed dimensions, 4 mil thickness, closure type, and pack count — then reorder by exact SKU PB3765RP100.
How do these bags close, and how are they shipped? And can I use them for food?
The closure is listed as Full-Width Single-Track Reclosable Zipper, so the bag closes without separate tape or heat. This listing is sold as one pack of 100 bags — roughly $0.34 per bag at the current pack 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 (Low-Density Polyethylene), a material commonly used in food packaging, and the manufacturer spec sheet for this item lists "Compliance: FDA and 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.
