Abstract

The invention relates to a method for the production of polyamide nanocomposites made from base polymers comprising aromatic components and organically-modified phyllosilicates in a double-screw extruder with a front- feeder and a side-feeder. Said method is characterised in that a portion (A) from 8 to 15 wt. % of a granulate of the base polymer is introduced in the front-feeder of the double-screw extruder and the main portion (B) of said granulate of the base polymer is introduced by means of the side feeder of the double-screw extruder and that 2 to 8 wt. % of the modified phyllosilicate is introduced into the melt of the granulate portion (A) of the base polymer, whereby the wt. % proportions relate to the finished polyamide nanocomposite. According to the invention, packaging materials with high UV absorption and improved gas and aroma barrier effect can be produced by said method. Furthermore, the corresponding packagings the use thereof and moulded bodies produced by means of said method are disclosed.
