About this item

Heavy-duty 4 mil Minigrip® reclosable poly bags deliver durability with clarity for food storage and product protection. The single-track zipper extends the full width for reliable sealing and moisture resistance.

This listing is one specification only: 12x12" 4 Mil Minigrip Reclosable Poly Bags, Case of 500. Packrift publishes no color options for this product; it is one product, not a clear color range.
Common questions
What actually fits inside a 12x12" bag?
The listed size is 12x12". 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.
How does 4 mil compare with lighter or heavier film?
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 Polyethylene.
Can a nearby size or thickness replace MG3775?
Not as an exact replacement. The closest sizes in this line are 12x10" and 12x15" (same 4 mil film), and the same 12x12" 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 MG3775.
Do these bags reseal, and how do they arrive?
The closure is listed as Minigrip® Premium Red Line™ Heavy-Duty Zipper, so the bag closes without separate tape or heat. This listing is sold as one case of 500 bags — roughly $0.38 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.
