About this item

12x10" clear flat poly bags in 4 mil polyethylene, a heavy-duty film for parts, hardware, and bulk contents. Packed 750 per roll (SKU AB321); this is a second listing of the same BOX case stock at the same price.
Open-top flat design: seal with twist ties, bag tape, or an impulse sealer (sold separately). Keeps parts, hardware, and products visible while protecting them from dust and moisture. Order by the roll of 750.
Common questions
How do I know if my item fits the 12" W x 10" H size?
The listed size is 12" W x 10" H. 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.
Can I swap AB321 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 8" W x 10" H and 10" W x 15" H; any size change alters the usable interior. Before switching, match the listed dimensions, 4 mil thickness, and roll count — then reorder by exact SKU AB321.
How do I close these bags, and how do they ship? And can I use them for food?
These are open-top bags — close them with a heat sealer, bag tape, twist ties, or staples, whichever fits your workflow. This listing is sold as one roll of 750 bags — roughly $0.27 per bag at the current roll 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: poly film like this is commonly used in food packaging, and the manufacturer spec sheet for this item lists "Certifications: 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.
