Common questions
How do I know if my item fits the 10x12" size?
The listed size is 10x12". 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 LDPE Polyethylene (4 Mil).
Can I swap MG3770 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 9x12" and 10x13" (same 4 mil film), and the same 10x12" size is also stocked in 2 and 3 mil. Before switching, match the listed dimensions, 4 mil thickness, closure type, and case count — then reorder by exact SKU MG3770.
Do these bags reseal, and how do they arrive? And can I use them for food?
The closure is listed as Single-Track Minigrip® Reclosable Zipper, so the bag closes without separate tape or heat. This listing is sold as one case of 500 bags — roughly $0.33 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 LDPE Polyethylene (4 Mil), a material commonly used in food packaging, and the manufacturer spec sheet for this item lists "Regulatory Compliance: FDA & 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.
