Abstract: Disclosed are single-sided stretch cling films having a cling layer, a release layer, and a core layer. The core layer is located between the cling layer and the release layer. The ding layer includes a blend of an olefin block copolymer and an ethylene-based polymer. The present films exhibit improved cling force compared to using a random ethylene copolymer in the cling layer.
