Estimating the term…
The present invention relates to a multi-layer oriented shrink film comprising at least one skin layer comprising a polystyrene material and at least one core layer comprising a polyolefin layer. The films are preferably primarily oriented in either the machine or the cross direction. These films are ideally suited for use as a shrink label which can be applied either as a CD shrink sleeve or applied using a continuous roll process. The films ideally have an overall density of less than 1.0 g/cm3, to facilitate recycling efforts.
A multi-layer oriented shrink film comprising at least one skin layer comprising an amorphous glassy polymer material and at least one core layer comprising a polyolefin layer wherein the shrink film has been subjected to either biaxial orientation with preferential orientation of at least two times in either the machine or cross direction or monoaxial orientation;
