Common questions
How much usable room does the 4x18" size really have?
The listed size is 4x18". 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 2 mil the right thickness for my use?
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.
Is there a drop-in substitute for PB404?
Not as an exact replacement. The closest sizes in this line are 4x16" and 4x20" (same 2 mil film), and the same 4x18" size is also stocked in 3 and 4 mil. Before switching, match the listed dimensions, 2 mil thickness, and case count — then reorder by exact SKU PB404.
What do I need to seal these, and what does a full order look like? And can I use them for food?
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 1,000 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. On food use: poly film like this is commonly used in food packaging, but food-contact compliance is certified per product lot. Check the spec sheet or contact us for documentation before direct food contact.
