ABSTRACT:
This invention is directed to a method of forming a vinylidene chloride interpolymer having enhanced barrier to atmospheric gas and water vapor. This enhanced barrier is achieved by fabricating the vinylidene chloride interpolymer into an article in a manner which allows between about 5 and about 50 percent crystallization to occur in the vinylidene chloride interpolymer while at a temperature above about 90.degree. C. and before it is allowed to cool below about 90.degree. C.
