A polymer article having a thin coating on at least one of its side is produced. The coating comprises a first coating of SiO x C y H z which is a plasma polymerized tetramethylsilane deposited on the surface on the polymer article, the x value being between 0 and 1.7, the y value being between 0.5 and 0.8, the z value being between 0.35 and 0.6 for said first SiO x C y H z coating and a second coating of SiO x C y H z which is a plasma polymerized tetramethylsilane deposited on the surface on said first coating, the x value being between 1.7 and 1.99, the y value being between 0.2 and 0.7, the z value being between 0.2 and 0.35 for said second SiO x C y H z coating. An oxidizing gas such as oxygen is used at least for the deposition of the second coating. The method is suitable to produce washable containers having reduced tendency of being stained. |
