Compostable Resealable Sandwich Bags, 25 Count
A reasonable single-use swap where reuse is not realistic. A lunch container outlasts any bag; the Seal Cup or a mason jar does this job without a film.
Certified compostable Mater-Bi sandwich bags with a resealable zipper, BPI listed under ASTM D6400. A real cert and honest resin disclosure, but still a bioplastic film in use, so it sits mid band like the rest of its category.

About BioBag
BioBag makes certified compostable bags from Mater-Bi, a compostable resin the brand names outright, which most bag makers do not. The resealable zipper is part of the same compostable construction, and the bags are BPA-free, PFAS-free, and freezer safe per the brand.
