Abstract:
Film formed from a polyethylene resin composition which obeys a dynamic rheological relationship at 190° C. between melt storage modulus G′, measured in Pa and at a dynamic frequency where the loss modulus G″=3000 Pa, and dynamic complex viscosity η*100, measured in Pa·s at 100 rad/s, such that (a) G′(G″=3000)>−0.86η*100+z where z=3800, and at the same time (b) G′(G″=3000)>0.875η*100−y where y=650, and having an impact strength (DDT) of at least 250 g, measured on 15 μm thick film (blown under conditions with BUR=5:1 and Neck Height=8×D) conditioned for 48 hours at 20°-25° C., according to ASTM D1709.
