Transparency (20%): Does the brand disclose ingredients, sourcing, and manufacturing?
Durability (20%): How long does it last? Longer-lasting products reduce plastic waste over time.

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. Canned foods lined with BPA epoxy, plastic-wrapped meats, and microwave-safe plastic containers are among the highest-exposure sources.
Why We Rated It This Way
Pyrex's glass containers are a significant improvement over plastic food storage. The glass is completely inert. Important: the plastic lids should not be microwaved — remove the lid before microwaving and use a glass plate as a cover instead.
