Common questions
How much usable room does the 18x20" size really have?
The listed size is 18x20". 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 LDPE Polyethylene.
Can I swap PB3678 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 13x18" and 26x28"; any size change alters the usable interior. Before switching, match the listed dimensions, 2 mil thickness, and case count — then reorder by exact SKU PB3678.
What does a full order look like, and where does it ship from?
This listing is sold as one case of 500 bags — roughly $0.26 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.
