Packaging container, in particular cup, tub or the like, made of plastic material and process for the production thereof

摘要

A packaging container 1, for example in the form of a cup or tub, is made of plastic material which has a plurality of different material layers 2 and 5 to 8 joined to one another. To obtain high barrier properties against the simultaneous effect of molecular oxygen and water, a base vessel and/or outer vessel 2, produced with a relatively thick wall has a single layer injection-moulded or thermoformed part, is distributed in its wall in the circumferential direction and provided with vent holes 14 at least in various vertical regions. A relatively thin plastic multilayer composite film 3 is laid flatly against the inside of the base vessel and/or outer vessel 2 as an inner layer and joined thereto, sealing or covering the holes 14 (Fig. 1). <IMAGE>
