Document Type and Number:
WIPO Patent Application WO/2012/098077
Kind Code:
A3
Abstract:
The invention relates to a method for producing multilayer objects from a polymer melt, especially in an injection mould, especially preforms having a barrier layer, wherein a viscosity, especially a shear speed, of the melt is determined. According to the invention, the viscosity, especially the shear speed, of at least one layer is determined in the injection mould and optionally monitored and/or regulated.
