First claim
Opening claim text (preview).
What is claimed is: 1 . A container comprising a propylene, ethylene, 1-hexene terpolymer wherein: (i) the content of ethylene derived units ranges from 0.5 wt % to 2.0 wt %; (ii) the content of 1-hexene derived units ranges from 1.5 wt % to 5.5 wt %; (iii) the content of ethylene derived units fulfills the following equation (I); C2<C6*0.65 (I); wherein C2 is the content of ethylene derived units wt % and C6 is the content of 1-hexene derived units wt %; and (iv) the melt flow rate MFR measured according to ISO 1133 (230° C., 2.16 kg) ranges from 15 to 80 g/10 min. 2 . The container of claim 1 wherein the content of 1-hexene derived units ranges from 1.8 wt % to 5.0 wt %. 3 . The container of claim 1 , wherein the content of ethylene derived units ranges from 0.7 wt % to 1.5 wt %. 4 . The container of claim 1 , wherein equation (I) is C2<C6*0.50. 5 . The container of claim 1 wherein the melt flow rate, MFR, measured according to ISO 1133 (230° C., 2.16 kg) ranges from 20 to 50 g/10 min. 6 . The container of claim 1 , wherein the container impact test as measured on a container having 0.4 mm wall thick at 23° C. produces a value of greater than 4.5 J. 7 . The container of claim 1 , wherein the container has a top load value as measured on a container having 0.4 mm wall thick of greater than 200 N.
