Beschreibung
Zusammenfassung:	Polyethylene recyclable composite article comprises multilayer film having first layer comprising polyolefin with a melting point ≤190° C., second layer comprising second polymer selected from amorphous polyamide, polyamide with melt point 191-205° C., polyvinylidene chloride w/melt point 191-205° C., and/or EVOH w/melt point 191-205° C., and tie layer between the first layer and the second layer. The multilayer film is bonded to itself or another component. The second polymer makes up 1 to 10 wt % of composite article weight, and composite article exhibits a composite melt index of from 0.5 to 4 grams/10 min at 190° C. and 2.16 kg in a Composite Melt Index Test. A corresponding polyethylene recyclable multilayer film also exhibits 0.5 to 4 grams/10 min at 190° C. and 2.16 kg in a Composite Melt Index Test.
