About this item
SKU PB390BK100PK — 4" × 6", 2 Mil, Black. Sold as a case of 100, shipped from US warehouses.
4x6" black flat poly bags in 2 mil polyethylene, the most popular general-purpose weight for light to medium weight products. Packed 100 per case (SKU PB390BK100PK); 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 case of 100.
Common questions
How much usable room does the 4x6" size really have?
The listed size is 4x6". 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 2 mil film mean in practice?
A mil is one-thousandth of an inch, so 2 mil film is 2/1000" 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 2 Mil Low-Density Polyethylene (LDPE).
Can a nearby size or thickness replace PB390BK100PK?
Not as an exact replacement. The closest size in this line is 6" Width x 9" Length; any size change alters the usable interior. Before switching, match the listed dimensions, 2 mil thickness, and case count — then reorder by exact SKU PB390BK100PK.
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 100 bags — roughly $0.039 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.
