Estimating the term…
A multilayer polymer film comprising at least one core layer disposed between two skin layers, wherein at least one of the core layers, one of the skin layers, or both one of the core layers and one of the skin layers comprises a saturated organic fatty amide (SOFA) slip agent. A multilayer polymer film comprising an effective amount of a SOFA slip agent in at least one core layer such that the film exhibits blocking of equal to or less than about 75 grams. A method of packaging a product comprising providing a package fabricated from such films and placing the product in the package, wherein loose dust is not applied to the exterior of the package to reduce blocking. A method for the reduction of the presence of wax on the surface of a multilayer polymer film comprising adding a SOFA slip agent to a core layer of the film.
A multilayer polymer film comprising at least one core layer disposed between two skin layers, wherein at least one of the core layers comprises a saturated organic fatty amide (SOFA) slip agent, wherein at least one of the skin layers consists of low density polyethylene, optionally an unsaturated organic fatty amide (UOFA) slip agent, and optionally an antiblock agent.
A multilayer polymer film comprising:
A multilayer polymer film consisting essentially of at least one core layer disposed between two skin layers, wherein the core layer comprises a saturated organic fatty amide (SOFA) slip agent, and wherein the skin layers consist of branched low density polyethylene and an antiblock agent.
