Thin oriented plastic strips and tape
Abstract
Abstract A PLASTIC TAPE UNIFORM THICKNESS OR ORIENTABLE POLYMERIC MATERIAL DRAWN FROM ITS ORGINAL LENGTH TO A FULLY STRETCHED AND ORIENTED CONDITION IN WHICH THE WIDTH TO THICKNESS RATIO OF THE ORIENTED TAPE IS GREATER THAN THAT OBTAINED BY FREELY STRETCHING THE ORGINAL LENGTH OF MATERIAL LONGITUDINALLY TO ITS NATURAL DRAW RATIO. THIS TAPE IS PRODUCED BY PULLING A LENGTH OF THE ORIENTABLE MATERIAL IN AN ORIENTED CONDITION THROUGH AN ELONGATED, CONFINED PASSAGE IN A MANNER TO STRETCH THE ORIGINAL LENGTH TO A PERMANENTLY ELONGATED LENGTH IN AN ORIENTED CONDITION AND IN WHICH THE NARROWEST DIMENSION OF THE CONFINED PASSAGE ESTABLISHING THE THICKNESS OF THE FULLY ORIENTED TAPE IS LESS THAN THE THICKNESS WHICH THE ORINGINAL LENGTH OF ORIENTED MATERIAL WOULD ASSUME WHEN LONGITUDINALLY FREELY DRAWN TO ITS NATURAL DRAW RATIO.
