Common questions
How much usable room does the 5x7" size really have?
The listed size is 5x7". 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 Static Shielding Polyethylene.
Can a nearby size or thickness replace STC121?
Not as an exact replacement. The closest sizes in this line are 4x8" and 5x8"; any size change alters the usable interior. Before switching, match the listed dimensions, 3.1 mil thickness, closure type, and case count — then reorder by exact SKU STC121.
Do these bags reseal, and how do they arrive?
The closure is listed as Heat Sealable, so the bag closes without separate tape or heat. This listing is sold as one case of 1,000 bags — roughly $0.15 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.
