1 LLDPE made via Spherilene Process
22502 is a LLDPE blown
fi
lm grade designed for applications re-
quiring ease of processing and good optical properties even at low
extrusion temperature. This resin is well suited for blending with
LDPE and for general purpose uses, including agricultural applica-
tions.
