About this item
SKU PB3841 — 20" × 30", 4 Mil, Clear. Sold as a case of 250, shipped from US warehouses.
20x30" clear reclosable poly bags in 4 mil polyethylene, a heavy-duty film for parts, hardware, and bulk contents. Packed 250 per case (SKU PB3841); this is a second listing of the same BOX case stock at the same price.
Open-top reclosable design: seal with twist ties, bag tape, or an impulse sealer (sold separately). Keeps parts, hardware, and products visible while protecting them from dust and moisture. Order by the case of 250.
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.
