A flexible oriented plastic sheet of high tensile strength and which is resistant to corrosion and highly resistant to splitting when penetrated by a pointed article. The flexible oriented sheet of the invention can be cut into desired shapes and sizes so as to be useful in a variety of applications, such as roofing batten bars and fencing materials, which require high resistance to splitting and fastener pull-through. The sheets are produced by melt extruding and orienting a composition comprising a major amount of polyethylene terephthalate (PET) and a minor amount of a polyolefin, preferably polypropylene.
