HMF-0856 is a certified prime grade Hexene copolymer MEDIUM MOLECULAR WEIGHT developed for production of thin gauged high stiffness paper-like Blown films. HMF-0856 features BROAD molecular weight distribution for improved processability at lower extruder pressure, excellent film drawdown, and good combination of high film stiffness with good film strength and improved barrier properties. HMF-0856 can be easily processed in HMW high stalk film equipment or in conventional film lines equipped with die gap = 0.75 to 1.25 = mm.. HMF-0856 applications include deli, meat & cheese wrap films, cereal box liners, notion and millinery bags, small shoppers, multi-wall and single liners, lamination films, coextrusion of films for stand-up-still pouches, and as substitute films for grease-proof waxed and acid free papers. Minimum recommended film gauge is 12 microns (0.5 mil), and processing temperature 195° to 205° C. HMF-0856 complies with FDR regulation 21CFR 177.1520 (c) 3.2 (a) and with most international regulations concerning the use of Polyethylene in contact with food articles.
