Heat-shrinkable sheets (thickness 0.040 to 0.120 in., or 1-3 mm) and films (thickness 0.001 to 0.020 in., or 0.025 to 0.5 mm) are fabricated from many of the same materials as shrinkable tubing. They are produced by extrusion as a tube, sheet, or blown film. Irradiation is done by the equipment shown... 

Heat shrink sheets are used for many of fhe same applications as heavy wall shrink tubing. The advantage of the sheet over a tube is that it can be conveniently slipped over the area to be protected, for example, over continuously installed cable. There are many methods to close the heat-shrinkable sheets, such as zippers, rail and channel, heat-sealable bonds, etc., some of them patented. ...

The film can then be fiattened and wound up as a tube or slit to obtain a single sheet. A polyvinylidene chloride film obtained in this way is heat-shrinkable at temperatures above SO C. If a heat-stabilised film is desired, an annealing step is applied by re-inffating the film and leading it through a radiant-heating tunnel (d). The third set of nip rolls (c) rotates at the same rate as the second set, and the air pressure in the bubble prevents the film from shrinking in the transverse direction. This is very effective...
