Means for packaging objects by means of a sheet of heat-shrink material, and corresponding packaging machine

摘要

A method of wrapping an object with a heat-shrinkable material. A sheet of the heat-shrinkable material is heated to its frosting temperature and then fitted around the object like a sleeve so that leading and trailing ends of the sheet overlap and are welded together. The object and the sleeve are allowed to cool to shrink the sleeve onto the object.
