Here's the modern day brown paper grocery bag. The outside looks like a paper bag, while the inside is lined with a 3mm aluminum foam liner. The bag is made with 50% recycled kraft paper backed with non-woven polypropylene. There is a hook and loop closure at the top to keep it closed. It has two 20" webbed handles. It's perfect for carrying frozen/cold products home from the grocery store or to a potluck. You can drop in an ice pack (not included) to keep your items cold.
