A recyclable backpack is made from recyclable plastic material, and is formed with two shoulder straps 1 in order that a user's hands may be free. The straps 1 may be folded over several times to give them more strength. The bag is closed using flap 2, which may be sealed using toggles or a sticky strip. A cardboard insert 3 may be used to protect the user's back from sharp contents. The insert 3 is formed with a crescent on its lower edge to avoid puncturing the bag.
