More user-friendly metallocene-catalyzed resin grades

Dow Plastics has recently announced the introduction of two new grades of AFFINITY polyolefin plastomers (POPs) made via the company’s constrained geometry and catalyst process technology, INSITE. The two new resins, AFFINITY PF 1146 and AFFINITY PL 1888, contain an optimized slip and antiblock formula, which offer processors improved coefficient of friction (COF) control with reduced blocking, for film that is easier to machine and process. In addition, according to Dow, these resins are formulated to reduce gel generation and to process on narrow die gap and/or high rate extrusion equipment. AFFINITY PF 1146 is designed for demanding sealant applications, and is suited for dry food goods such as cereal and crackers, as well as for fresh-cut produce. AFFINITY PL 1888 is suited for sealant applications where a balance of optics, abuse properties and sealant characteristics are desired.
