MULTI-LAYERED PLASTIC FILM WITH SEPARATION EFFECT
An at least monoaxially stretched, multi-layer film with separation effect and a total thickness of ≦18 μm which has on at least one surface an at least partial embossing.
1 . A multilayer polymeric film with release effect, which is oriented at least monoaxially in machine direction with an orientation of at least 1:2 and is comprised at least to an extent of 50 wt % of polyolefins, and which has a total thickness ≦18 μm, having an at least partial embossment on at least one surface, the embossed elevation of the at least partial embossment being ≧5 μm as measured according to DIN 53370 2006.
2 . A polymeric film as claimed in claim 1 , having an orientation in machine direction of at least 1:5.
3 . A polymeric film as claimed in claim 1 , wherein the release effect of the polymeric film is based on the at least partial embossment of at least one surface.
4 . A polymeric film as claimed in claim 1 , wherein the polymeric film has a release coating on at least one of its surfaces.
5 . A polymeric film as claimed in claim 1 , wherein the polymeric film has a shrinkage lower by at least 50% in comparison to a corresponding unembossed oriented polymeric film.
6 . A polymeric film as claimed in claim 1 , wherein the embossment and/or release coating that generates the release effect is present over substantially the whole surface area, or over a partial area of the surface of the polymeric film.
7 . A polymeric film as claimed in claim 1 , wherein the polymeric film is comprised to an extent of at least 70 wt % of polyolefins.
8 . A polymeric film as claimed in claim 1 , wherein as polyethylenes LDPE, MDPE, LLDPE or a mixture of at least two of the mentioned PE are used.
9 . A polymeric film as claimed in claim 1 , wherein at least one layer of the polymeric film is based on a mixture of at least one PE and one PP.
10 . A polymeric film as claimed in claim 1 , wherein the film has a barrier layer against gases, against migration of low molecular mass organic compounds and/or impairment of taste or of odor, and/or against moisture and/or fats and/or oils.
11 . A polymeric film as claimed in claim 10 , wherein the barrier layer is made up of ethylene/vinyl alcohol copolymers, polyvinyl alcohols, polyamides, polyesters and/or polyether-polyamide block copolymers.
12 . A release film or protective film comprising the multilayer polymeric film with release effect of claim 1 .
13 . A removable packaging film and/or protective film for self-adhesive articles of any kind comprising the multilayer polymeric film with release effect of claim 1 .
14 . A carrier layer for adhesive tapes comprising the multilayer polymeric film with release effect of claim 1 .
15 . A low-noise, optionally detachable packaging material for individually packed hygiene articles or incontinence products comprising the multilayer polymeric film with release effect of claim 1 .
16 . A flexible packaging material composed of polymeric film as claimed in claim 1 for individually packaged, adhesive articles.
17 . A flexible packaging material composed of a polymeric film as claimed in claim 1 for individually packaged, self-adhesive hygiene articles or incontinence articles.
