Common questions
How much usable room does the 12" x 18" (Inside Usable Dimensions) size really have?
The listed size is 12" x 18" (Inside Usable Dimensions). 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.
Is 6 mil the right thickness for my use?
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.
Can I swap PB3890 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 12x16" and 13x18" (same 6 mil film), and the same 12" x 18" (Inside Usable Dimensions) 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 PB3890.
Do these bags reseal, and how do they arrive?
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 500 bags — roughly $0.53 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.
