Disclosed is a container, made by folding, with fold-in flaps, for packaging food. The container can be recycled economically, i.e. with a profit. The material consists of metal sheet coated with a plastics skin which, when the metal is recovered, produces no residual matter or pollutants. The edges of the container are welded to each other by the plastics coating. After bending open the flaps, the container can be easily laid flat by hand (thus reducing its volume) without it springing back and used containers can be collected in compact form in a recycling container and transported in the recycling container to the recycling facility where the metal is recovered by melting.
