  The invention relates to a device that includes a substrate and a thin film of a photo-switchable adhesive layer applied to at least one surface of the substrate. A method of releasably supporting a product that includes adhering a product onto the thin film of the device and exposing the thin film to light sufficient to cause a change in the adhesive strength of the thin film. A method of making the device is also disclosed.
