Abstract: A package possessing superior tightness properties against gases, in particular oxygen gas, for the distribution of goods. The package, which, for example, may be a plastic bottle, has a coating applied on the outer walls of the package, the coating comprising a silicon oxide compound of the general chemical formula SiO.sub.x, where x may vary from 1.8 to 2.2. The silicon oxide coating is deposited on the package walls by vacuum deposition, preferably chemical plasma vapor deposition (CPVD), by means of which the coating is deposited in the form of a very thin but nevertheless extremely tight continuous coating of a thickness of less than 2000 .ANG.. After one occasion of use, the package may be cleaned using conventional washing and rinsing solutions which efficiently remove the preceding coating, whereafter the package is provided with a new coating prior to a new product filling.
