PLASTIC FILMS: THEIR USEFULNESS IN THE FABRICATION OF TRANSPARENT BARRIER MATERIALS

Data is presented on the properties of ten recently received plastic films along with data on thirty-five films reported earlier. Fifteen films, selected from this group as representative of plastic film types, were tested for fungus resistance, corrosiveness to metals, and stability to storage at elevated temperatures. Polyvinylidene chloride, rubber hydrochloride and polyvinyl chloride were found to be corrosive cellophane and polyvinyl chloride are not fungus resistant cellophane, polyvinylidene chloride and rubber hydrochloride have poor stability to storage polyethylene, and polyvinyl chloride are rated as having only fair storage stability. Recommendations are given for composite films which would result in acceptable transparent barrier materials for military packaging applications.
