摘要： Film layers made from formulated ethylene polymer compositions are disclosed. Film layers made from such formulated compositions have surprisingly good heat seal properties, and an especially good reduction in heat seal initiation temperature. The ethylene polymer compositions have at least one homogeneously branched ethylene/alpha-olefin interpolymer and at least one homogeneously or heterogeneously branched ethylene polymer which has a lower melt index than the first mentioned component. The first homogeneously branched ethylene/alpha-olefin interpolymer has a melt index higher than that of the formulated composition.

摘要： A method and device for unwrapping self-adhering films at reduced noise levels are disclosed. The method and device include means to maintain a sufficiently high unwrapping take-off angle during the unwrapping and dispensing or unwinding of film rollstock. Suitable means provide for substantial acceleration and adjustment of the rollstock rotational speed relative to the speed of the first power driven member of an unwrapping apparatus, or the use of one or more carefully positioned deflector members. The method and device is particularly useful in unwrapping and dispensing operations of high cling stretch wrap films involving the use of turntable-style power driven equipment as well as in unwrapping and unwinding operations of pressure-sensitive adhesive tapes.
