Common questions
What actually fits inside a 28x40" bag?
The listed size is 28x40". 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 4 mil film mean in practice?
A mil is one-thousandth of an inch, so 4 mil film is 4/1000" 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 4 Mil Low-Density Polyethylene (LDPE).
Is there a drop-in substitute for PB13010?
Not as an exact replacement. The closest sizes in this line are 20x30" and 36x42"; any size change alters the usable interior. Before switching, match the listed dimensions and 4 mil thickness — then reorder by exact SKU PB13010.
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.
