Abstract
The present invention concerns a multi-layer film for cling film applications comprising at least three layers, with two outer layers, at least one core layer, preferably exactly one core layer, wherein at least one or both outer layer(s) comprise(s) between 73 wt. % and 99.5 wt. % or between 73 wt. % and <99.5 wt. % of LLDPE based on the total weight of the respective layer and between 0.5 wt. % and 7 wt. % of HDPE based on the total weight of the respective layer.
Claims20
A multi-layer film for cling film applications comprising at least three layers, with two outer layers, at least one core layer, wherein at least one outer layer comprises between 73 wt. % and 99.5 wt. % of linear low density polyethylene based on the total weight of the respective layer and between 0.5 wt. % and 7 wt. % of high density polyethylene based on the total weight of the respective layer.
(canceled)
A multi-layer film for cling film applications comprising:
- at least three layers, with two outer layers, at least one core layer,
- wherein at least one outer layer comprises between 73 and 99 wt. % of linear low density polyethylene based on the total weight of the respective layer and between 0.8 and 3.5 wt. % of high density polyethylene based on the total weight of the respective layer;
- wherein at least one or in both outer layer(s) and or in the core layer comprises 0.5 and 15 wt. % anti-fog agent, based on the total weight of the layer;
- wherein a melt flow index of the linear low density polyethylene in at least one or in both of the outer layer(s) ranges from 0.1 to 5 g/10 min;
- wherein the linear low density polyethylene in at least one or in both of the outer layers and/or in the core layer is a copolymer of ethylene and 1-octene;
- wherein the linear low density polyethylene in at least one or both of the outer layer(s) or in the core layer has a density between 0.900 to 0.934 g/cm3;
- wherein a core layer comprises a blends of >50 and 89.5 wt. % LLDPE and between 10 and 30 wt. % LDPE, based on the total weight of the core layer;
- and
- wherein the melt flow index as determined using ISO1133:2011 (190° C./2.16 kg) of the HDPE ranges from 0.1 to 4 g/10 min.
