I have been looking for alternatives to plastic food storage and discovered the Kaderron 43 oz 50 Pack Large Paper Bowls with Lids.
The paper bowls are thicker and are made of Kraft paper ala composable biodegrable bagasse bowls and are leakproof and microwave safe and works great for hot/cold use.
I have used them and have had no leakage problems.
It’s important to note that while you do get biodegradable paper bowls, you do get plastic lids but it was the only way to seal things in and keep things fresh. So, while the bowls are eco-friendly, plastic lid…not so much.
But still, better for the environment than what I used to use before and for 50 bowls for $32, not bad at all! Recommended!
