A method of producing containers in which one strip element is folded to provide uniform, transverse, channel-shaped portions and a second strip member is placed over the channel-shaped portions, the lateral, longitudinal side edges of the member being folded down against the edges of the channel-shaped portions and sealed thereto to form a container. The side edges of the member being cut to provide transverse slits therein to form flaps of a size to cover the open ends of each channel-shaped portion to thus facilitate manufacture of the containers. |
