Embodiment Construction

[0073] The invention will now be described by way of examples.

[0074] In an example of the present invention, the two mixtures A & B detailed in Table 1 were prepared by:

[0075] i) Pre-mix the dry ingredients in a high speed Henschel mixer

[0076] ii) The blend was melt mixed in a co-rotating twin-screw extruder at 200°C

[0077] iii) The strands were quenched with water before pelletizing into small (nominal 2mm-3mm) pellets.

[0078]

[0079]Pellets of Mixture A were loaded into one single screw extruder and pellets of Mixture B were loaded into a second single screw extruder. Both extruders fed a coextrusion multi-tube die. The film exits the die at approximately 500 microns and is drawn to the desired thickness by varying the draw speed onto heated rolls. The films were coextruded to form rolls of composite transparent film having a nominal total thickness of 70 μm, with each individual layer having a nominal thickness of 35 μm. The contained particles are loc...
