The invention relates to the production and application of heat shrinkable films obtained from a mixture of a styrene and butadiene copolymer and resins of the polyolefin type, which are produced by any of the known processes for the production of polymer films. The heat and mechanical properties of the films obtained by this invention make them appropriate to be used, amongst other applications and without restriction to the scope of the invention, as heat shrinkable labels, security stamps and packages of the wrapping type, thermoformed packages of the ampulla type and, in general, for any type of packed dodge such as the packing body security containment used for wrapping audiocassettes, videocassettes, books, magazines, etc., in order to protect them against abuse, as well as in general applications of packaging materials. |
