Microchannels on plastic film for cooling or dispensing

Researchers have developed a new high-volume production method for hot embossing microscopic channel structures onto large areas of plastic film at a low cost for use.
The channels can be embedded either into hard or soft plastics, depending on the purpose of use. For example, the feel and shape of a soft and elastic plastic film is better suited for integration into a coat compared to rigid plastics, which in turn are better suited for application in card format, such as a handy travel perfume dispenser that is the size of a credit card. Other possible uses of the thin cards include very precise dosing of medicine or serving strong spices in restaurants (News Release VTT, 5 November 2015).
