Glass Food Storage Set

Glass containers and glass lids with a food-grade silicone seal. Mostly glass and independently lab-tested, but the silicone seal is a synthetic, so a low-plastic 1 rather than fully plastic-free.

1 / 10 Low plastic footprint $$$$

Borosilicate glass containers with glass lids, so no plastic touches food. Stackable and oven-safe, independently lab-tested for toxic substances.

How this score breaks down

Plastic in the product and its packaging Little to no plastic
Glass food storage where the containers are borosilicate glass and the lids are glass with a BPA-free silicone seal, so no plastic touches food. The set is independently lab-tested for toxic substances.
Microplastic shedding and leaching Doesn't shed
The borosilicate glass containers and lids are inert and shed nothing. The lid gasket is food-grade silicone, a synthetic that is not a petroleum plastic and sheds far less than plastic, though it can release trace particles or siloxanes under heat or with age.
End of life: persistence and recovery Recovers well
Plastic-free where it counts; glass containers with glass lids. Recyclable, repairable, or genuinely recovered; low persistence.
Plastic-derived chemicals of concern No leaching concern
No PFAS, PTFE, BPA, or other leaching plastics in food or heat contact.
Transparency and verification Fully disclosed
Independently lab-tested; results published

Strengths

Trade-offs

  • The lid seal is food-grade silicone, a synthetic polymer: not a petroleum plastic, but fossil-fuel made and able to release trace siloxanes or particles under heat or with age
  • Premium price for a glass set
