Common questions
What actually fits inside a 6x18" bag?
The listed size is 6x18". 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.
Is 3.1 mil the right thickness for my use?
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 Metallized Polyethylene.
Is there a drop-in substitute for STC131?
Not as an exact replacement. The closest sizes in this line are 6x16" and 6x24"; any size change alters the usable interior. Before switching, match the listed dimensions, 3.1 mil thickness, and closure type — then reorder by exact SKU STC131.
How do these bags close, and how are they shipped?
The closure is listed as Heat Sealable, so the bag closes without separate tape or heat. 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.
