About this item
SKU PB917 — 20" × 42", 3 Mil, Clear. Sold as a case of 250, shipped from US warehouses.
20x42" clear flat poly bags in 3 mil polyethylene, a medium-duty film for heavier or sharper items. Packed 250 per case (SKU PB917); 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 do I know if my item fits the 20x42" size?
The listed size is 20x42". 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 3 mil compare with lighter or heavier film?
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 PB917 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 18x42" and 22x40" (same 3 mil film), and the same 20x42" 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 PB917.
How do I close these bags, and how do they ship?
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 $0.64 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.
