Common questions
How much usable room does the 28x28" size really have?
The listed size is 28x28". The catalog lists inside-usable dimensions of 28 x 28 inches, so that measurement is what your item has to fit within.
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).
Is there a drop-in substitute for PB3845?
Not as an exact replacement. The closest sizes in this line are 26x26" and 30x30" (same 4 mil film), and the same 28x28" size is also stocked in 2 mil. Before switching, match the listed dimensions, 4 mil thickness, closure type, and case count — then reorder by exact SKU PB3845.
Do these bags reseal, and how do they arrive?
The closure is listed as Full-Width Single Track Zipper, so the bag closes without separate tape or heat. This listing is sold as one case of 100 bags — roughly $1.63 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.
