Common questions
How do I know if my item fits the 20" x 20" size?
The listed size is 20" x 20". The catalog lists inside-usable dimensions of 20" x 20", so that measurement is what your item has to fit within.
How does 4 mil compare with lighter or heavier film?
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 PB3836 for the next size up or down?
Not as an exact replacement. The closest size in this line is 16" W x 20" L (usable interior); any size change alters the usable interior. Before switching, match the listed dimensions, 4 mil thickness, closure type, and case count — then reorder by exact SKU PB3836.
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 Full-Width Single-Track Zipper, so the bag closes without separate tape or heat. This listing is sold as one case of 250 bags — roughly $0.63 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 & 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.
