Glass Meal Prep Containers (10-Pack)

B
PFR Grade
Good — mostly plastic-free with minor concerns
Borosilicate glass containers. No BPA, no BPS, no phthalates in the glass. However, the plastic lids contain BPA-free polypropylene — do not microwave with lids on. A significant improvement over plastic containers.

Moderate Exposure Risk — Why This Product Category Matters

Food packaging is one of the most direct routes of plastic chemical exposure. BPA, BPS, phthalates, and PFAS migrate from packaging into food — especially with heat, acidity, or fat content.

Why We Rated It This Way

Prep Naturals' glass meal prep containers are a significant improvement over plastic containers. The glass is completely inert. Important: remove the plastic lid before microwaving and use a glass plate as a cover instead.
