Common questions
How much usable room does the 3" W x 4" H size really have?
The listed size is 3" W x 4" H. 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 1 mil film mean in practice?
A mil is one-thousandth of an inch, so 1 mil film is 1/1000" 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 AB323?
Not as an exact replacement. The closest sizes in this line are 2x3" and 3x5" (same 1 mil film), and the same 3" W x 4" H size is also stocked in 2 mil. Before switching, match the listed dimensions, 1 mil thickness, and roll count — then reorder by exact SKU AB323.
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 roll of 4,000 bags — roughly $0.013 per bag at the current roll 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.
