摘要： A polymeric film has at least one surface on which chitosan has been immobilised so as to be substantially resistant to leaching and have a strong antimicrobial activity. The polymeric film may be a polyolefin film such as a biaxially orientated polypropylene film. A process immobilises chitosan on a polymeric surface so as to be resistant to leaching and have a strong antimicrobial activity by applying chitosan to a polymeric film surface which has been activated before addition of chitosan to the surface by plasma activation at atmospheric pressure.
