About this item

4x4" clear reclosable poly bags in 8 mil polyethylene, an extra heavy-duty film for heavy or abrasive contents. Packed 1000 per case (SKU PB3858); 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 1000.
Common questions
What actually fits inside a 4x4" bag?
The listed size is 4x4". 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 8 mil the right thickness for my use?
A mil is one-thousandth of an inch, so 8 mil film is 8/1000" 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 Low-Density Polyethylene (LDPE), 8 Mil Thickness.
Can a nearby size or thickness replace PB3858?
Not as an exact replacement. The closest sizes in this line are 3x5" and 4x6" (same 8 mil film), and the same 4x4" size is also stocked in 2 and 4 mil. Before switching, match the listed dimensions, 8 mil thickness, closure type, and case count — then reorder by exact SKU PB3858.
How do these bags close, and how are they shipped? And can I use them for food?
The closure is listed as Full-Width Track Zipper (Reclosable/Resealable), so the bag closes without separate tape or heat. This listing is sold as one case of 1,000 bags — roughly $0.076 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 Low-Density Polyethylene (LDPE), 8 Mil Thickness, a material commonly used in food packaging, and the manufacturer spec sheet for this item lists "Regulatory Compliance: FDA & USDA Approved for Food Contact". Food-contact compliance is still certified per product lot, so check the spec sheet or contact us for lot documentation before direct food contact.
