Common questions
What actually fits inside a 36x42" bag?
The listed size is 36x42". 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 1.5 mil the right thickness for my use?
A mil is one-thousandth of an inch, so 1.5 mil film is 1.5/1000" 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 1.5 Mil Low-Density Polyethylene (LDPE).
Can a nearby size or thickness replace PB3100?
Not as an exact replacement. The closest sizes in this line are 22x24" and 38x60" (same 1.5 mil film), and the same 36x42" size is also stocked in 4 mil. Before switching, match the listed dimensions and 1.5 mil thickness — then reorder by exact SKU PB3100.
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. 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.
