Kraft Paper Lunch Bag vs. Pyrex Glass Food Storage Containers

Materials

• Kraft paper

Common claims

• Recyclable
• Grease resistant
• Biodegradable

Concerns / watch-outs

• Some kraft paper bags use PFAS-based grease-resistant coatings — check for explicit PFAS-free labeling
• Single-use product; reusable containers are more sustainable

Notes

Standard uncoated kraft paper is one of the safest single-use food contact materials. Verify the bag is PFAS-free if it claims grease resistance.

Cleaner alternatives

• stainless steel food container
• beeswax food wrap

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
