I know that these are paper containers but can they be reused a few times

I have reused these, but be sure to get all the previous food content out of the corners. They are great containers. Have bought them again and again. Nancy W

Hi, the containers complying the astm6400 or bpi regulation?

RESPONSE FROM THE OFFICIAL SELLER - FROZEN DESSERT SUPPLIES: Thank you for asking! These are made with FDA approved, compostable paper and a PLA coating. As of right now, these must be composted at a composting facility, they are not biodegradable. They currently do meet the ASTM6400 standards for compostability. We love nothing more than to wow our customers! If you have any other questions please contact us through Amazon's Messaging Service or call our Award-Winning Customer Solutions Team at 480-428-1999.
