The invention relates to a method for producing a multilayer film. In particular, the invention relates to a method for producing a multilayer film comprising at least one polymeric carrier, at least one bonding primer layer and at least one coating, said process comprising the following steps: a) creating a a polymeric support; b) optionally, performing a surface pretreatment on at least one side of said support; c) coating at least one side of said support with a primer dispersion comprising core-shell polymer particles; d) drying the dispersion to produce a tie primer layer; e) coating the bonding primer layer with at least one coating of at least one metal and / or at least one oxide of metal and / or silicon oxide, or at least one layer of ink, or at least one layer of adhesive. The invention also relates to the use of a primer dispersion comprising core-bark polymer particles to provide a bonding primer layer which enables control of barrier properties and / or adhesion properties of a multilayer film comprising a polymeric support, a bonding primer layer and a coating. |
