A retort bag is a soft and lightweight multi-layer packaging for canned goods that can be stored at room temperature. Such canned food is very light, it is practical to take them with you on hikes. The packaging from the retort package can be taken with you or burned, thus being disposed of. There are canned vegetables and meats of this type. Canned meat is especially popular. Typically, such canned food does not contain as much lard as stew, and consists almost entirely of meat, which makes them not only tastier, but also healthier.
