TWB 04/16 Hochdruckbehandelte Tray-Verpackungen

Untersuchung von strukturellen Veränderungen mit Raman-Spektroskopie

A Raman spectroscopic study of high pressure treated packages with modified atmosphere showed the influence of high pressure processing under modified atmosphere and layer thickness on the
crystallinity of PE. The crystallinity of PE-MD and PE-LLD has increased dependent on the location of the film sample on the tray. Also the influence of treatment history on the crystallinity has been shown.
