Abstract

A packaging system for a film roll containing, inter alia, a highly sensitive film web is disclosed. The system is made up of at least two end walls, with centrally arranged cylindrical plug-on protuberances or centering protuberances for receiving the winding sleeve which bears the film web, and are connected in a releasible, but sealing manner to the end walls via tensioning elements and sealing elements. The system further includes an inner winding sleeve and an outer protective sleeve, and thus, together with the end walls, sealing elements and tensioning elements, forms a closed packaging around the film roll.
