Abstract: A carrier for a container package holding an array of cans each of which has an annular bead on the upper end thereof comprising a sheet of flexible plastic material having a plurality of openings forming an array for receiving the ends of the cans and at least one film of plastic material coextensive with the sheet and bonded to the periphery of the sheet. The sheet is made as a coextruded sheet comprising a first relatively thicker layer and a second relatively thin layer adjacent the film. The second layer has a melting point lower than that of the first layer or the film and facilitates the bonding of the film to the sheet by heat. In a modified form two layers of film are bonded to the sheet.

Abstract: In the process of making relief printing plates a liquid photopolymerizably layer having substantially identical negatives on each of its two sides and being in registration and also having a transparent substrate is exposed to an external light source so that both sides are exposed to the same image and after removal of the negatives the unexposed areas of the plate are removed.
