A multilayer stretch film comprising at least a first layer (i) with cling
properties comprising an olefin (co)polymer composition, a second layer
(ii) with slip properties comprising another olefin (co)polymer
composition and if desired at least one core layer (iii) comprising an
olefin (co)polymer composition between the first layer (i) and the second
layer (ii). The outer surface of the first layer (i) with cling
properties is provided with a non-stretchable thin film of one or more
slip agent(s) covering at least 50% up to 100% of the outer surface of
the first layer (i), lowering the cling properties of the unstretched
composite film. The thin film of slip agent(s) is provided either by
direct application of the slip agent(s) onto the outer surface or by use
of slip agent(s) having limited compatibility with the (co)polymer
composition as additive in the (co)polymer composition of the first layer
(i). The limited compatibility of the slip agent(s) with the (co)polymer
composition of the first layer (i) results in migration of the slip
agent(s) to the outer surface and formation of a non-stretchable thin
film at the outer surface of the first layer (i). The multilayer stretch
film is preferably composed substantially entirely of ethylene or
propylene (co)polymer compositions or mixtures thereof. The invention
includes a method of preparing a multilayer stretch film according to the
present invention by extrusion and the use of the multilayer stretch film
in a method for stretch wrapping operations of articles or groups of
articles.
