About this item
SKU PB3994 — 18" × 20", 2 Mil, Clear. Sold as a case of 500, shipped from US warehouses.
18x20" white reclosable poly bags in 2 mil polyethylene, the most popular general-purpose weight for light to medium weight products. Packed 500 per case (SKU PB3994); this is a second listing of the same BOX case stock at the same price.
Open-top reclosable 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 500.
Common questions
How much usable room does the 18x20" size really have?
The listed size is 18x20". 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 2 mil film mean in practice?
A mil is one-thousandth of an inch, so 2 mil film is 2/1000" 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 2 Mil LDPE Polyethylene.
Can I swap PB3994 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 14x20" and 18x24" (same 2 mil film), and the same 18x20" size is also stocked in 4 and 6 mil. Before switching, match the listed dimensions, 2 mil thickness, closure type, and case count — then reorder by exact SKU PB3994.
Do these bags reseal, and how do they arrive? And can I use them for food?
The closure is listed as Reclosable Zipper, so the bag closes without separate tape or heat. This listing is sold as one case of 500 bags — roughly $0.34 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: the film is 2 Mil LDPE Polyethylene, a material commonly used in food packaging, and the manufacturer spec sheet for this item lists "FDA/USDA Compliance: Yes - Food Contact 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.
