Common questions
How do I know if my item fits the 9x12" size?
The listed size is 9x12". The catalog lists inside-usable dimensions of 9" W x 12" H, so that measurement is what your item has to fit within.
Is 4 mil the right thickness for my use?
A mil is one-thousandth of an inch, so 4 mil film is 4/1000" 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 4 Mil LDPE Polyethylene.
Can I swap PB4004 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 10x10" and 10x12" (same 4 mil film), and the same 9x12" size is also stocked in 2 and 6 mil. Before switching, match the listed dimensions, 4 mil thickness, closure type, and case count — then reorder by exact SKU PB4004.
How do these bags close, and how are they shipped? And can I use them for food?
The closure is listed as Reclosable Zipper Lock, so the bag closes without separate tape or heat. This listing is sold as one case of 1,000 bags — roughly $0.16 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 4 Mil LDPE Polyethylene, a material commonly used in food packaging, and the manufacturer spec sheet for this item lists "Regulatory Compliance: FDA and USDA 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.
