Stainless Steel Food Container vs. Glass Food Storage with Snap Lids

Materials

• 18/8 stainless steel

Common claims

• BPA-free
• Durable
• Non-porous

Concerns / watch-outs

• Nickel and chromium can leach in very small amounts with prolonged acidic food contact — generally negligible for most people
• Not microwave safe

Notes

One of the most inert, durable food contact materials. Excellent for lunchboxes, meal prep, and replacing plastic containers.

Cleaner alternatives

• borosilicate glass container
• mason jar

Materials

• Borosilicate glass
• BPA-free plastic snap lids

Common claims

• Oven, microwave, and freezer safe
• Non-porous glass
• BPA-free lids

Concerns / watch-outs

• Lids are typically polypropylene (PP) — avoid microwaving with lid on
• Glass can break if dropped on hard floors

Notes

Best practice for food storage. Glass body is completely inert. Just don't microwave with the plastic lid on to avoid leaching.

Cleaner alternatives

• pyrex glass containers
• anchor hocking glass
