Abstract
A thermoplastic stretch wrap film exhibits a significant level of cling on one surface but no appreciable cling force on the other, the latter surface exhibiting a slide property when in contact with a film or like surface due to the presence of particulate antiblock agent mechanically bonded thereto. The film can be used to overwrap one or a group of articles to form a unitized packaged unit employing any of the known and conventional tension-wrapping techniques. Because of its one-sided cling and slide capabilities, pallet loads overwrapped with the film and in mutual contact avoid film tearing or destruction when the pallet loads are separated from each other.
