  • the slip skin layer comprises a low coefficient of friction and the cling layer contains a lesser amount of cling additive.
  • the invention described herein comprises an improved stretch film incorporating a slip skin layer on one side of the stretch film.
  • the slip skin layer significantly improves the stretch film’s performance by reducing contact between wrapped materials; reducing pallet-to-pallet distortion and product damage; maintaining adequate wrapping integrity; and unwinding easily for application.
  • the stretch film further comprises a low film-to-film and outside-to- outside coefficient of friction.
  • the stretch film further comprises a low unwinding noise.

  • the stretch film comprises a good clarity.
  • the stretch film is economical.
  • the stretch film is technically feasible to produce.
  • the stretch film incorporating a slip skin layer differs from known one-sided cling films by eliminating, alleviating and minimizing pallet-to-pallet distortion and product damage caused by mechanical communication, abrasion, distortion and blocking during transport and storage.
  • the stretch film further enables undersize pallet use as an additional measure to prevent product damage, thereby reducing costs. Therefore, the stretch film protects products in virtually any wrapping operation.
  • the stretch film comprises a slip skin layer with a low coefficient of friction and provides a good clarity, a moderate cling, a low unwinding noise and a low unwinding force.

  • the total thickness of the film is greater than 25 microns. In a particular though non-limiting embodiment, the total thickness ranges from about 8 microns to about 50 microns. In another particular though non-limiting embodiment, the total thickness of the film is less than about 13 microns. In another particular though non-limiting embodiment, the film thickness is about 10 micron.
  • the slip layer is incorporated into machine film. In other embodiments, the slip layer is incorporated into hand film or other types of stretch film. In still further embodiments, the slip layer is used in high elongation or high loading force film structures.
