HDPE Plastic Food Container (#2) vs. Pyrex Glass Food Storage Containers

Materials

• High-density polyethylene (HDPE, recycling #2)

Common claims

• BPA-free
• Dishwasher safe
• Lightweight

Concerns / watch-outs

• HDPE is one of the safer plastics but can still leach additives at elevated temperatures
• Avoid microwaving or storing hot food — cold and room temperature use is lower risk

Notes

Among the safer plastic types for cold food storage. Avoid heat and replace if cracked or scratched, as degraded surfaces leach more readily.

Cleaner alternatives

• stainless steel food container
• borosilicate glass container

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
