Styroflex is a new member of BASF's polystyrene product line. Its pred
ominant features are: high transparency, toughness, oxygen permeabilit
y and good recovery (memory effect). Thus, Styroflex is the ideal raw
material for the production of fresh meat packaging film. The best tec
hnical solution consists of a 3 layer coextruded thin film made of Sty
roflex and polyolefin. Styroflex-based films have superior toughness c
ompared to conventional films, eg PVC, resulting in improved processin
g characteristics on automatic packaging machines. These properties co
uld be reproduced in numerous field tests. Pork, beef and poultry, wra
pped in Styroflex displayed the same organoleptics, color and positive
microbiological behavior compared to conventional PVC film.
