Flexible, breathable polymer film and method for production thereof

摘要

An economical, flexible, breathable polymer film composite modified in at least one of its surfaces by the formation of pores opening out in a funnel shape at the surface thereof, with a nanoscale particle system and which is particularly suitable for packaging purposes. The modification further includes at least one composite layer construction made from a binding agent layer of chemically inert inorganic nanoparticles and a lining layer of hydrophilic non-toxic metal oxide particles which are photocatalytically active under short wave light radiation and which have an anti-bacterial and self-cleaning effect.
