Common questions
What actually fits inside a 12x15" bag?
The listed size is 12x15". The catalog lists inside-usable dimensions of 12 x 15 inches, so that measurement is what your item has to fit within.
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 I swap MG3777 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 12x12" and 12x16" (same 4 mil film), and the same 12x15" 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 MG3777.
Do these bags reseal, and how do they arrive?
The closure is listed as Single-Track Heavy-Duty Minigrip® Zipper, so the bag closes without separate tape or heat. This listing is sold as one case of 500 bags — roughly $0.45 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.
