OPP: directional, stretched polypropylene is one of polypropyleneAnd bidirectional polypropylene (BOPP)OPP major products:OPP tape: polypropylene film substrate, has high tensile strength, light weight, non-toxic, environmental protection, use of a wide range of advantagesOPP bottle: light weight, low cost, transparency improvement, good heat resistance, suitable for hot filling.
