Printed electronic heaters

This is on blood bags you find in hospitals.  It is not cold, but gets warm by heaters printed in plastic blood bag.  So blood inside is warm. 
It is expected that warm blood mitigates side effects of new blood when it goes through a body.

When circuits are printed on plastic films, surface of these plastic films must be dead flat.  Stainless steel vacuum conveyor serves dead flat surface and continuous printing on roll-to-roll stream.
