About this item
SKU AB323 — 3" × 4", 1 Mil, Clear. Sold as a roll of 4000, shipped from US warehouses.
3x4" clear flat poly bags in 1 mil polyethylene, an economical light-weight film for lightweight items. Packed 4000 per roll (SKU AB323); this is a second listing of the same BOX case stock at the same price.
Open-top flat 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 roll of 4000.
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.
