PHF-8 is a certified prime grade Polypropylene specially designed for Film EXTRUSON by Tubular Water Quench - TWQ - process. PHF-8 combines excellent processability and good melt thermal stability, with films exhibiting clarity, good impact strength, modulus, good barrier to fats and oils, and good chemical resistance. PHF-8 applications include film for articles requiring excellent see-through clarity such as textiles, soft goods and pastries, pre-cooked foods sterilizable bags, bags to pack cooked foods, and paper over-wrap products. PHF-8 recommended processing temperature is between 210° to 230°C. PHF-8 complies with FDA regulation 21CFR 177.1520 (a)(1) (b) (c)1.1, and most international regulations concerning Polypropylene use in contact with food articles.
