Green plastic barrier packaging material and process advances
from By Don Rosato
Modern innovations have made it possible to keep food fresh for a much longer time without changing the taste or aroma. While proven barrier materials extend product shelf life by impeding oxygen ingress into a package, oxygen scavengers "capture" oxygen within a sealed package to ensure that oxygen does not react with the food product. Nanotechnology is increasingly used to enhance packaging barrier properties. But let's start off by taking a closer look at recyclable plastic barrier material.
