Pyrex Glass Food Storage Containers vs. Reusable Mesh Produce Bags

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

• Organic cotton or polyester mesh

Common claims

• Plastic-free grocery shopping
• Washable
• Breathable

Concerns / watch-outs

• Polyester mesh bags shed microfibers in the washing machine; organic cotton mesh is preferable

Notes

One of the simplest plastic-reduction swaps for grocery shopping. Choose organic cotton mesh over polyester to avoid microfiber shedding.

Cleaner alternatives

• beeswax food wrap
• silicone storage bag
