CERTENE HWF-0852

高密度聚乙烯

Muehlstein

产品说明：

HWF-0852 is a certified High Molecular Weight Hexene copolymer grade, developed for production of thin-gauged high stiffness paper-like blown films. HWF-0852 features BIMODAL and BROAD molecular weight distribution which greatly improve processability in HDPE blow film equipment, offers outstanding film mechanical properties and high film drawdown. HWF-0852 applications include shoppers, grocery bags, merchant and produce bags, refuse sacks, single and multiwall liners, lamination and meat cheese wrap films, and as substitute films for grease-proof waxed and acid free papers. Minimum recommended film gauge is 0.5 mil, and melt processing temperature between 210 to 230°C.
