Common questions
What actually fits inside a 13x18" bag?
The listed size is 13x18". 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.
What does 4 mil film mean in practice?
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.
Can a nearby size or thickness replace PB1226?
Not as an exact replacement. The closest sizes in this line are 12 x 18 inches and 14" x 18" (Flat) (same 4 mil film), and the same 13x18" size is also stocked in 2 mil. Before switching, match the listed dimensions, 4 mil thickness, and case count — then reorder by exact SKU PB1226.
What do I need to seal these, and what does a full order look like?
These are open-top bags — close them with a heat sealer, bag tape, twist ties, or staples, whichever fits your workflow. This listing is sold as one case of 500 bags — roughly $0.22 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.
