IMPROVED RESIN COMPOSITIONS FOR EXTRUSION COATING |
摘要 |
A composition of matter suitable for use in extrusion coating applications is disclosed. The composition comprises a blend of particular LLDPE with particular LDPE. The LLDPE has the following characteristics: a density in the range of from 0.89 g/cc to 0.97 g/cc; an MWD less than 2.8; a melt index (I2) in the range of 4.0 to 25 g/10 min; a Comonomer Distribution Constant in the range of from greater than from 45 to 400; and a vinyl unsaturation of less than 0.12 vinyls per one thousand carbon atoms present in the backbone of the ethylene-based polymer composition. The LDPE has a melt index (I2) in the range of 0.1 to 15 g/10 min, and has a melt strength which satisfies the inequality: Log Melt strength (cN)>1.14−0.6×Log I2(g/10 min,190° C.) |
