Pyrex Glass Food Storage Containers vs. Stainless Steel Kids Lunch Box

Materials

• Tempered soda-lime glass
• Plastic or silicone lids

Common claims

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

Concerns / watch-outs

• Modern Pyrex sold in the US uses tempered soda-lime glass, not borosilicate — more susceptible to thermal shock than older versions
• Plastic lids may contain BPA; look for confirmed BPA-free lids or use silicone alternatives

Notes

Pyrex glass is one of the most recommended non-toxic food storage options. The glass body is completely inert. Replace plastic lids if they become scratched or stained.

Cleaner alternatives

• borosilicate glass container
• mason jar

Materials

• 18/8 food-grade stainless steel
• Stainless or silicone interior dividers

Common claims

• BPA and lead-free
• Leak-proof
• Easy-open latch

Concerns / watch-outs

• Not microwave safe; pack cold lunches or use a thermos for hot foods
• Check that lid gaskets and any inner components are food-grade silicone

Notes

One of the best investments for a low-tox family lunch routine. Brands like PlanetBox and LunchBots use fully food-grade stainless construction inside and out.
