The container for packaging is made from a thermoplastic plastic and is coated in the region of the inner surface thereof, such that a release of components contained within the plastic into the product packed in the container is prevented or at least significantly reduced. The coating can be applied by means of a plasma coating. The device for the production of preforms and the method for production of containers is essentially based on a direct coupling of a reactor for production of the plastic to an injection moulding device for the production of preforms. The preforms are then moulded to give the container by a blow forming process and the inner surface thereof is then provided with the coating.
Container for packaging products, which has a wall made of a thermoplastic material that contains at least one constituent that can be released at least from certain regions of the container into the interior of the container, wherein the constituent that can be released is present in the thermoplastic material in a concentration that is above the concentration that is allowable for the packaging of the products, and that at least a portion of the inner surface of the wall of the container is coated in such a way that a release rate of the constituent in the direction of the interior of the container is realized which, at most, is equal to a release rate that would be realized with the use of a thermoplastic material which has a concentration of the constituent that can be released that is near the allowable limit but which does not have an inner coating.
Installation for producing preforms from a thermoplastic material, which has an injection-molding machine with cavities for the preforms, wherein the injection-molding machine is coupled with a reactor for producing the thermoplastic material.
Method for producing containers from a thermoplastic material, in which the plastic is produced in a reactor and then shaped into preforms by an injection-molding machine, and in which the preforms are formed into containers by blow molding, and then at least a portion of the inner surface of the containers is coated by a plasma coating process, wherein the reactor is directly connected to the injection-molding machine, and that the plastic produced by the reactor is fed from the reactor to the injection-molding machine in the form of a melt.
