Clear, high-barrier polymer-platelet composite multilayer structures |
摘要 |
This invention relates to novel multilayer formed articles including, but not limited to containers such as bottles, tubes, pipes, preforms and films (including oriented films such as biaxially oriented) comprising a melt processible resin having dispersed therein a platelet filler. The multilayer formed articles have improved barrier while maintaining excellent clarity. More particularly, the multilayer structures of the present invention display haze values of less than about 2% and carrier resins which are substantially free from platelet particles having a diameter greater than about 15 microns.
