Common questions
What actually fits inside a 12x16" bag?
The listed size is 12x16". 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 Conductive Polymer.
Is there a drop-in substitute for STC338?
Not as an exact replacement. The closest sizes in this line are 11x15" and 12x18"; 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 STC338.
Do these bags reseal, and how do they arrive?
The closure is listed as Reclosable Zip-Top Seal, so the bag closes without separate tape or heat. This listing is sold as one case of 100 bags — roughly $0.94 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.
