Modeling of deformation phenomena in volume label during its operation

Abstract

BIt was considered in the article the research of physical and mechanical properties of materials based on PVC film ORACAL and RITRAMA that used in the production of volume labels. In particular, it was shown the changes of dependences between linear deformation of printed and unprinted films and the value of stress with regard to their minimum and maximum values. It was also established that deformation properties of the films are different in the transverse and longitudinal directions, which should be considered when producing labels. It was conducted the modeling of stress-strain state of volume label when gluing it to the surfaces of various shapes. We considered the boundary conditions for displacement and stress of labels layer components with regard to the chemical structure of epoxy resins and their physical and mechanical characteristics.
