Common questions
How much usable room does the 20x30" size really have?
The listed size is 20x30". The catalog lists inside-usable dimensions of 20" W x 30" H, 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 Low-Density Polyethylene (LDPE).
Can I swap PB3841 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 16x30" and 24x30" (same 4 mil film), and the same 20x30" 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 PB3841.
How do these bags close, and how are they shipped? And can I use them for food?
The closure is listed as Single-Track Full-Width Zipper (Reclosable/Resealable), so the bag closes without separate tape or heat. This listing is sold as one case of 250 bags — roughly $0.94 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 Low-Density Polyethylene (LDPE), a material commonly used in food packaging, and the manufacturer spec sheet for this item lists "FDA/USDA Compliant: Yes". Food-contact compliance is still certified per product lot, so check the spec sheet or contact us for lot documentation before direct food contact.
