摘要：This paper discusses the problems connected with applying a biocidal substance onto the surface of a blown extrudedpolyethylene film in order to improve the functional properties of the film while maintaining its processing propertiesunchanged. The objective of the study was to determine the relationship between biocide application method andselected properties of the tube film. Two methods of biocide application onto the film surface were developed: onerelied on spraying the biocide onto the hot melt surface directly during the extrusion process, while in the other thebiocide was sprayed horizontally onto the blown film after the extrusion process. Biocide distribution uniformity, fric-tion coefficients and surface free energy of the modified film were examined, and the quality and mechanical strengthof heat- sealed joints were estimated. In addition, the geometric properties of the blown film were determined.
关键词：blown film extrusion; film modification; surface free energy; sealability; film geometric properties.
