Stasher
Stasher is honest about what it is: a silicone answer to single-use plastic zip bags, not a plastic-free product. The bags are platinum food-grade silicone with a Pinch-Loc seal, so nothing petroleum-plastic touches food, but silicone is still a synthetic elastomer — the win is durability and reuse, not plastic elimination. Reasonable as the reusable replacement for Ziplocs; just don't mistake it for glass or steel.
How clear are their specs?
Materials are stated plainly — platinum food-grade silicone with a Pinch-Loc seal — and the brand doesn't overclaim it as plastic-free.
