Abstract: The disclosure provides ethylene/α-olefin copolymer based co-extruded, multi-layer films, including barrier films and non-barrier films, and articles of manufacture that include the films, such as flexible bags and containers for flowable materials. The films and articles that include the films have improved flex-crak reisstance and toughness. The films and articles that include the films have good barrier properties as the barrier films include a core layer of ethylene-vinyl alcohol (EVOH) copolymer having a high ethylene content. The low amount of EVOH copolymer in the total film that is needed to achieve the flex-crack resistance, toughness, and good barrier properties, further allow for the recycling of the films and articles of manufacture.
