Parslen ZH520J Is a Modified Homopolymer Designed for the VeryHigh Speed Production of Coextruded BOPP Films. Product Description: • Parslen ZH520J has been developed for coextrusion lines with a very high output and linear speed. The product allows an outstanding extrusion stability and thickness variation control, especially on cascade lines the product provides also a very high drawability and readiness to a two way orientation. • BOPP films produced with Parslen ZH520J feature good mechanical properties, high impact strength and puncture resistance, even at low temperatures. The films form an excellent barrier against moisture, odours, oils, fats and oxidation and feature h igh transparency, high gloss and good printability after corona treatment. Application: • Coextruded film with a thickness of 20 to 40 μm is used for the automatic packaging of bakery products, snacks and pasta as well as tor theoverwrapping of boxes and cigarette packets
