TERPOLYMERS FOR CAPS AND CLOSURES

Polymer compositions may comprise propylene, present in a range of 80 to 95 wt % of the polymer composition, and two comonomers selected from a group comprising ethylene and C4-C10 alpha olefins, wherein the polymer composition has a total content of the comonomers in the range of 5 to 20 wt % of th...

Beschreibung
Zusammenfassung:	Polymer compositions may comprise propylene, present in a range of 80 to 95 wt % of the polymer composition, and two comonomers selected from a group comprising ethylene and C4-C10 alpha olefins, wherein the polymer composition has a total content of the comonomers in the range of 5 to 20 wt % of the polymer composition. Cap liners may be formed from the polymer compositions. Caps may comprise a closure formed from polypropylene and a polypropylene-based cap liner that lines at least a portion of the closure.
