MULTILAYER FILM FOR MANUFACTURING PACKAGING CONTAINER, METHOD FOR MANUFACTURING SUCH MULTILAYER FILM AS WELL AS PACKAGING CONTAINER

摘要

FIELD: chemistry.;SUBSTANCE: film for manufacturing packaging containers has a layered structure of several layers formed by package materials, the inner layer thereof is made as a thermo-welding layer, and the outer layer allows the possibility of attaching a closure with the mechanism of opening the packaging container primarily by thermo-welding, and which have a weakened zone in the closure location area. The weakened zone is located on the side of the inner layer, and is formed by at least partial reduction of its thickness, wherein said weakened area, at first by its circular shape in cross section, is matched to the arrangement of blades located on the reference diameter of the mechanism as a component of the mechanism of opening the packaging container, with which the closure is equipped.;EFFECT: invention provides the design improvement of the multilayer film for the packaging containers production, so that it, in the interaction with the mechanism for opening the packaging containers which is included in the closure equipped therewith, designed for its ripping and having blades, allows the possibility of its reliable cutting.;8 cl, 5 dwg
