About this item
SKU PB874 — 12" × 36", 3 Mil, Clear. Sold as a case of 250, shipped from US warehouses.
12x36" clear flat poly bags in 3 mil polyethylene, a medium-duty film for heavier or sharper items. Packed 250 per case (SKU PB874); 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 case of 250.
Common questions
How much usable room does the 12x36" size really have?
The listed size is 12x36". 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.
Is 3 mil the right thickness for my use?
A mil is one-thousandth of an inch, so 3 mil film is 3/1000" 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.
Is there a drop-in substitute for PB874?
Not as an exact replacement. The closest sizes in this line are 10x36" and 14x36" (same 3 mil film), and the same 12x36" size is also stocked in 1 and 1.5 mil. Before switching, match the listed dimensions, 3 mil thickness, and case count — then reorder by exact SKU PB874.
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 case of 250 bags — roughly $0.42 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: poly film like this is commonly used in food packaging, and the manufacturer spec sheet for this item lists "Regulatory 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.
