Material Notes:
Low Density, Linear Polyethylene Film ResinCustomer Benefits: This unique broad molecular weight distribution resin has a wide processing window and produces film with an excellent combination of toughness and tensile. D252/257 may be used straight, in blends, or coextruded with HMW-HDPE, LLDPE, and LDPE. It is especially well suited in blends with LLDPE to increase melt strength and processing rate of LLDPE. In thick gauge heavy duty applications, the benefit of the high molecular weight tail is seen in puncture resistance. Processing is excellent on many types of equipment and under a variety of conditions, including high stalk. Meets FDA regulations for food packaging below cooking temperatures. D256 contains premium stabilizer.Applications: Heavy wall bagsProperty Comments: HDPE line, 4:1 BUR, .035" gap, 8" die, 56" FLH, 240 lbs/hr, 420°FData provided by Chevron Phillips Chemical Company LP.
