Common questions
How do I know if my item fits the 20x20" size?
The listed size is 20x20". The catalog lists inside-usable dimensions of 20" W x 20" H, so that measurement is what your item has to fit within.
How does 6 mil compare with lighter or heavier film?
A mil is one-thousandth of an inch, so 6 mil film is 6/1000" 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 6 Mil LDPE Polyethylene.
Is there a drop-in substitute for PB3906?
Not as an exact replacement. The closest sizes in this line are 18x20" and 20x24" (same 6 mil film), and the same 20x20" size is also stocked in 2 and 3 mil. Before switching, match the listed dimensions, 6 mil thickness, closure type, and case count — then reorder by exact SKU PB3906.
How do these bags close, and how are they shipped? And can I use them for food?
The closure is listed as Full-Width Single-Track Zipper, so the bag closes without separate tape or heat. This listing is sold as one case of 100 bags — roughly $1.02 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 6 Mil LDPE Polyethylene, a material commonly used in food packaging, and the manufacturer spec sheet for this item lists "Compliance: FDA & USDA 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.
