Common questions
What actually fits inside a 8x4x18" gusseted bag?
The listed size is 8x4x18" — the gusseted sides fold out so the bag can open to its listed depth and sit around blockier items. 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 1 mil the right thickness for my use?
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. This listing's material is specified as 1 Mil Low-Density Polyethylene (LDPE).
Can I swap PB13950 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 6x4x15" and 10x4x20" (same 1 mil film), and the same 8x4x18" size is also stocked in 1.5 and 2 mil. Before switching, match the listed dimensions and 1 mil thickness — then reorder by exact SKU PB13950.
How do I close these bags, and how do they ship?
These are open-top bags — close them with a heat sealer, bag tape, twist ties, or staples, whichever fits your workflow. 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.
