Material Notes:
ApplicationsPETROTHENE NA 345 is a series of homopolymer resins combining premium clarity with strength and stiffness. In addition, NA 345 exhibits good impact strength on both flat and creased film. NA 345 is recommended for textile packaging, light produce, bread bags and other thin packaging films enhanced by clarity and sparkle. The optimal values of NA 345 actually improve with decrease in film gauge and are maintained at a wide die gap settings. This fact leads to important cost savings. Film can be drawn down to a minimum gauge consistent with required physical properties, with the assurance that optical properties will not suffer, but improve. With wider die gaps back pressures are reduced, as are extrusion costs. Regulatory StatusNA 345 meets the requirements of the Food and Drug Administration regulation 21 CFR 177.1520. This regulation allows the use of this olefin polymer in "…articles or components of articles intended for use in contact with food…" Specific limitations or conditions of use may apply. Contact your Equistar sales representative for more information. Processing TechniquesSpecific recommendations for processing NA 345 can only be made when the processing conditions, equipment and end use are known. For further suggestions, contact your Equistar sales representative.Physical PropertiesThese are typical values and not to be construed as specific product limits.
