Abstract
The invention relates to a substrate coated with an oriented multilayer polymeric film comprising at least two layers of polymer particles oriented along two different directions with respect to one another. Such an oriented multilayer polymeric film has improved flexibility as well as improved gas barrier properties. A method of forming the film on a substrate is also disclosed.
