Common questions
What actually fits inside a 8x4x18" gusseted bag?
The listed size is 8x4x18" — the gusseted sides fold out so the bag can open to its listed depth and sit around blockier items. 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 2 mil compare with lighter or heavier film?
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 Low-Density Polyethylene (LDPE).
Can I swap PB4287 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 6x4x20" and 10x4x20" (same 2 mil film), and the same 8x4x18" size is also stocked in 1 and 1.5 mil. Before switching, match the listed dimensions, 2 mil thickness, closure type, and case count — then reorder by exact SKU PB4287.
How does the closure work, and what does a full order look like? And can I use them for food?
The closure is listed as Double-Track Reclosable Zipper, so the bag closes without separate tape or heat. This listing is sold as one case of 1,000 bags — roughly $0.11 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 Low-Density Polyethylene (LDPE), a material commonly used in food packaging, and the manufacturer spec sheet for this item lists "Regulatory Compliance: FDA and 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.
