Pyrex Glass Food Storage Containers vs. Natural Wax Paper

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

• Unbleached paper
• Food-grade paraffin or soy wax coating

Common claims

• Non-stick
• Grease resistant
• Biodegradable

Concerns / watch-outs

• Not oven safe — wax will melt at oven temperatures
• Some wax papers use chlorine-bleached paper; choose unbleached

Notes

Natural wax paper is a safer single-use wrap than PVC cling film for cold food wrapping. Not suitable for oven use or microwave.

Cleaner alternatives

• beeswax food wrap
• parchment paper
