FIELD: process engineering.SUBSTANCE: invention relates to thermoplastic films used as components of absorbing articles, packages, wrapping materials, etc. It includes first and second thin-sheet materials. Note here that first thin-sheet material comprises first polymer with first refracting properties while second thin-sheet material features second refracting properties. Painted thin-sheet material includes dye with interference effect built in, at least, one layer of painted thin-sheet material. Discrete lengthy elements feature diameter smaller than 500 mcm. Discrete lengthy elements feature H:D ratio making, at least, 0.2. Note here that proposed material comprises, at least 95 lengthy elements per 1 cm.EFFECT: expanded process performances.26 cl, 28 dwg, 6 ex |
