HEAT-SENSITIVE POLYMER MATERIAL FOR PRINTING |
摘要 |
FIELD: physics. ^ SUBSTANCE: heat shrinking film made from thermoplastic has areas with a modified structure and local shrinkage different from shrinkage of the whole film. Said areas appear after heat treatment and differ from the rest of the material on colour, transparency, direction of the lines of the printed pattern and/or are distinguished by surface microrelief. ^ EFFECT: invention provides printing products and film packaging with protection from copying and forgery and from non-regulated storage of a heat-sensitive product at high temperature. ^ 4 cl, 9 dwg, 4 ex |
