A vehicle tank, in particular for holding a fuel, in particular gasoline and/or diesel fuel, having: a first and a second partial shell, wherein the first and second partial shell are connected to one another in a partial shell joining area, and a barrier layer substantially, preferably completely, covering an outer surface of the first partial shell and an outer surface of the second partial shell, respectively, wherein the barrier layer spans the partial shell joining area on an outer surface of the vehicle tank.

The present invention relates to an opening device comprising a first portion on one side of a fibre based packaging laminate and a second portion on an opposite side of the fibre based packaging laminate, the first and second portion being formed in one and the same piece and joined by at least one material bridge extending through the packaging laminate. The present invention also relates to a method for manufacturing the opening device and to a packaging material to be used is such a method.

A color conversion film converts incident light into light with a wavelength longer than that of the incident light. The color conversion film is a laminate film including the following Layer(A) and Layer (B): Layer (A): a color conversion layer as a continuous layer containing at least one organic light-emitting material and a binder resin; and Layer (B): a transparent resin layer with an oxygen permeability of 1.0 cc/m.sup.2.Math.day.Math.atm or less.

The production of a plastic molded part utilizes a barrier layer embedded in plastic. Plastic is injection-molded successively in different cavities of the injection mold onto a three-dimensional preform made from a cut of a multi-layer barrier film, which multi-layer barrier film comprises a barrier layer coated with plastic on both sides. The plastic coating of the barrier film cut is at least superficially melted by the injected plastic melt. And the preform is supported by a support formed on the corresponding partial mold on the respective opposite side.
