Resealable bags with a genuine mechanical seal, not a carbon filter. Bags do one thing a pouch cannot: they cost little enough to use one per item and replace them freely — and unlike a liner, a closed seal has no odour path at all.
Specifications
- Ten bags, 6 × 4 in, 8 fl oz each
-
4 mil thick — roughly four times a supermarket freezer bag, which is why these survive being reused
- Multi-laminated, nylon-reinforced poly — food and medical grade, BPA free, phthalate free, no PEVA
-
Triple-track TRILOK zipper: three parallel tracks rather than one, so the seal does not open under pressure from inside
- Dishwasher safe and washable, so they are genuinely reusable rather than nominally so
- Made in the USA; 90-day returns
Where a bag beats a pouch
A carbon pouch handles smell through a filter layer, and that layer saturates over time. A properly sealed bag has no odour path at all while it is closed. For anything that gets sealed and then left alone — portioning, freezing, posting a sample to yourself — the bag is the better mechanism, and it is the cheaper one by an order of magnitude.
What they will not do
A bag is not rigid, so it protects nothing from being crushed, and it holds no humidity level of its own. Long-term storage still belongs in a jar — see Keep It Fresh. Where these earn their place is between the jar and the pocket.
