Common questions
How much usable room does the 36x42" size really have?
The listed size is 36x42". 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 3 mil film mean in practice?
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.
Can I swap PB948 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 34x40" and 40x42" (same 3 mil film), and the same 36x42" size is also stocked in 1 and 2 mil. Before switching, match the listed dimensions, 3 mil thickness, and case count — then reorder by exact SKU PB948.
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 100 bags — roughly $1.17 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 & 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.
