Blends of polyamide and polyester for barrier packaging

Abstract

A polymer composition comprising a blend of amorphous nylon copolymer and polyester that is useful in packaging applications where good barrier properties are desired. These compositions can be effectively processed using methods including extrusion blow molding and extrusion coating. When incorporated as a layer in a package, these blends exhibit good gas barrier properties and a reduced tendency to absorb flavor from a packaged product. These blends exhibit a combination of processibility and properties that is difficult to achieve with polyester alone.
