Abstract: A tube, in particular sausage casing, is composed of mutually connected sections which at the connection point, prior to connection, possess cut edges extending approximately at right angles to the longitudinal axis of the tube and parallel to each other. The sections are connected by an adhesive tape extending around the outside of the tube. When the tube, possessing two folded edges extending parallel to each other, is flattened, the part of the cut edges of one section extending from a first folded edge of the other opposite folded edge is situated within the tube and the other part of this cut edge, which extends from the second folded edge back to the first folded edge, is situated on the outside of the tube. Parts of the cut edge of the other section are situated in reversed arrangement, firstly on the outside of the tube and then within the tube.

Abstract: An improved release formulation for use in a heat transferable laminate wherein an ink design image is transferred from a carrier support to an article by application of heat to the carrier support. On transfer the release splits from the carrier and forms a protective coating over the transfered design. The improved release is coated onto the carrier as a solvent based-wax release. The release coating is then dried to evaporate the solvent contained therein. The improved release has the property that its constituents remain in solution down to temperatures approaching ambient temperature. Upon transfer, the release forms a protective coat which may be subjected to hot water. The improved release contains a montan wax, a rosin ester or hydrocarbon resin, a solvent, and ethylene-vinyl acetate copolymer having a low vinyl acetate content.
