PROCESS FOR FORMING MULTI LAYERED SHAPED FILM Russian patent published in 2019 - IPC B32B27/00 A61K9/70 

Abstract RU 2678037 C2

FIELD: general-purpose methods for applying liquids.

SUBSTANCE: invention relates to the production of film products. Method includes placing a first mask over the substrate, applying a first film-forming composition to the substrate through the first mask to form a first raw shape, removing the first mask, placing the second mask over the first raw shape, applying to the first raw shape a second film-forming composition through the second mask to form a second raw shape, removing the second mask, and hardening the first and second raw shapes to obtain a film product having a shape placed on the substrate.

EFFECT: process enables to produce on an industrial scale an inexpensive multi-layer film-shaped product without waste from cutting, wherein this product may be used independently of the substrate on which it is formed.
