Direct food contact daily. Silicone is far safer than plastic but still a synthetic polymer — heat exposure increases leaching risk with lower-grade silicone. Stasher uses platinum silicone, the safest grade.

Stasher discloses all materials publicly and uses no fillers, BPA, BPS, or phthalates. The packaging is 100% plastic-free cardboard.
Chemical & Health Analysis
Platinum silicone
Considered the safest synthetic polymer for food contact. Does not leach BPA, phthalates, or known endocrine disruptors. Inert at temperatures up to 400°F.
Conventional plastic zip bags (LDPE/LLDPE)
Low-density polyethylene releases trace plasticizers and antioxidant additives into food, particularly fatty foods. Cumulative daily exposure contributes to microplastic body burden.
