Common questions
How much usable room does the 4x4" size really have?
The listed size is 4x4". 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 4 mil the right thickness for my use?
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 LDPE (Low-Density Polyethylene).
Can I swap PB3988 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 3x4" and 4x6"; any size change alters the usable interior. Before switching, match the listed dimensions, 4 mil thickness, closure type, and case count — then reorder by exact SKU PB3988.
Do these bags reseal, and how do they arrive? And can I use them for food?
The closure is listed as Reclosable Zipper with White Write-On Block, so the bag closes without separate tape or heat. This listing is sold as one case of 1,000 bags — roughly $0.038 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: the film is 4 Mil LDPE (Low-Density Polyethylene), a material commonly used in food packaging, and the manufacturer spec sheet for this item lists "Certification: FDA and USDA Food Contact Approved". Food-contact compliance is still certified per product lot, so check the spec sheet or contact us for lot documentation before direct food contact.
