Common questions
How much usable room does the 8x18" size really have?
The listed size is 8x18". 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 Polystyrene.
Can I swap STC152 for the next size up or down?
Not as an exact replacement. The closest sizes in this line are 8x16" and 10" x 18" Open End; 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 STC152.
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 200 bags — roughly $0.59 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.
