Method of producing barrier layer and carrier body comprising such barrier layer

The invention relates to a method for producing a barrier layer and to a carrier body comprising such a barrier layer. The method for producing a barrier layer (22) on a polymer film (2) comprises thefollowing steps of: A) providing a carrier body (1) comprising the polymer film (2) made of at least one polymer, wherein polymer film (2) forms a barrier interface (20) of the carrier body (1); B) drying the barrier interface (20); C) exposing the barrier interface (20) to a reactant gas (4) or to a plurality of reactant gases (4) that do not undergo a chemical reaction with each other so as toallow the at least one reactant gas (4) to chemically react with the at least one polymer at least inside the polymer film (2) in the form of at least one chemical reaction, thereby forming the barrier layer (22); and D) removing at least one product gas (5) of the at least one chemical reaction. 本发明涉及屏障层的制备方法和包含这种屏障层的载体主体。用于在聚合物膜(2)上制备屏障层(22)的方法，包括以下步骤：A)提供包含由至少一种聚合物制成的聚合物膜(2)的载体主体(1)，所述聚合物膜(2)形成载体主体(1)的屏障界面(20)，B)干燥屏障界面(
