Abstract:
The multilayer container includes a container body having a multilayer structure and a multilayer head of the container. The multilayer body of the container has at least one barrier layer connected, on one side, to at least one thermoplastic layer and heat sealed in a longitudinal overlapping joint formed of the edges of these layers. The body has its external surface covered with a polymeric coating, and the multilayer head of the container includes at least one non-metallic barrier layer connected, on one side, to at least one thermoplastic layer and is wholly extruded in the co-extrusion process. The essence of the invention is also a method for producing such a container.
