COMPOSITE PLASTIC FILMS FOR FLEXIBLE TRANSPARENT PACKAGING.

Abstract

Five composite films were developed conforming to the MIL-F-22191A, Type 1 requirements at considerably reduced prices. Two are considered to be of a lesser quality with no particular advantages. One, composed of a fluorocarbon and a polyethylene-polyester blend has relatively low physical properties but is rather thin and is exceptionally transparent. Its estimated selling price is $1.00 per square yard. The remaining two films, both composed of fluorocarbon, oriented polypropylene and a polyolefin terpolymer have excellent physical properties. One of these, having a one-mil thickness of fluorocarbon has an MVTR considerably lower than the specification requirement, but it is more expensive ($1.30 per sq yd). The other, having a 1/2 mil fluorocarbon ply has a normal MVTR but is also the most inexpensive ($0.90 per sq yd) of those meeting the specification. (Author)
