Abstract

A laminate for manufacturing of packaging containers comprises a thermoformable base layer, a barrier layer and a laminate layer adjacent the barrier layer and directed towards the inside of the container contemplated. The base layer consists of polypropylene, foamed polypropylene, filled polypropylene, polyethylene terephtalate, filled polyethylene terephtalate, amorphous polyethylene terephtalate or filled amorphous polyethylene terephtalate, the barrier layer consists of aluminium, and an aluminium oxide coating, a silica coating, ethylene/vinyl alcohol, polyvinyl alcohol, metalized oriented polyethylene terephtalate or metalized oriented polypropylene, and the laminate layer consists of polypropylene, high density polyethylene, linear low density polyethylene, polyethylene terephtalate, amorphous polyethylene terephtalate, an adhesive plastic, a heat sealable plastic, a primer or a lacquer.
Furthermore, the invention relates to a method for the manufacturing of packaging containers by means of folding of a laminate according to the invention, the laminate being subjected to autoclaving or hot filling.
