Common questions
How much usable room does the 12x12" size really have?
The listed size is 12x12". Plan for contents slightly smaller than the nominal size — the usable interior runs a bit under the listed measurement once the bag takes shape around what you load into it.
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 LDPE Polyethylene (6 Mil Thickness).
Can I swap PB4030 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 10x12" and 12" W x 15" H (same 6 mil film), and the same 12x12" size is also stocked in 2 and 4 mil. Before switching, match the listed dimensions, 6 mil thickness, closure type, and case count — then reorder by exact SKU PB4030.
Do these bags reseal, and how do they arrive?
The closure is listed as Reclosable Zipper/White Block Write-On, so the bag closes without separate tape or heat. This listing is sold as one case of 500 bags — roughly $0.40 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.
