Abstract: The present subject matter provides a shrink film free of silicon-containing material, fluorine-containing material, and solvent-formed seams. The shrink film utilizes a water soluble layer covering an adhesive layer. The water soluble layer is in dry form and non-tacky, allowing processing of the shrink film subsequent to adhesive application to the shrink film.

The adhesive can be used to form a seam in the film and/or can be used to form a bond between the film and a substrate. The water soluble layer facilitates removal of an optional release liner from the adhesive. A substrate with the shrink film attached thereto and a related method of attaching a heat shrinkable film to a substrate are also disclosed.

In some applications, the temperature is less than 100 degrees Celsius and the time period is less than 5 seconds. The stack is removed from the heat and the slow cure electrically conductive epoxy continues to cure over a longer second period of time, such as a few hours to a day.
