These are a 7"x10" 6 mil Mylar bag. They are gold colored on the outside and silver on the inside. These are Retort bags, which means they are made to take the high heat of retort canning. This is a bag that you could safely use to rehydrate meals with boiling water right in the bag. A normal Mylar bag is not made to take the high heat and is not safe to use in this way.
