Common questions
How do I know if my item fits the 3x5" size?
The listed size is 3x5". 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.
What does 3.1 mil film mean in practice?
A mil is one-thousandth of an inch, so 3.1 mil film is 3.1/1000" 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 3.1 Mil Multi-Layer Polyethylene with Static Shielding.
Can a nearby size or thickness replace STC307?
Not as an exact replacement. The closest sizes in this line are 3x3" and 4x6" (same 3.1 mil film), and the same 3x5" size is also stocked in 3 mil. Before switching, match the listed dimensions, 3.1 mil thickness, closure type, and case count — then reorder by exact SKU STC307.
How do these bags close, and how are they shipped?
The closure is listed as Reclosable Zip-Top, so the bag closes without separate tape or heat. This listing is sold as one case of 500 bags — roughly $0.18 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.
