Material Notes:

CX7020 is a low-density polyethylene (LDPE) with excellent processability and low gel content. Those features allow for production of thin and highly uniform films. This product is identified as PE 113 according to ASTM D-4976-04a standard specification. It does not contain additives. Its applications include: smooth or embossed films for diapers, disposable sheets, etc.; films for lamination; injection-blow molding; and foamed applications. Recommended processing conditions for film extrusion are about 145 - 190 ºC.
