METHOD OF PRODUCING MULTILAYER FILM Russian patent published in 2020 - IPC B32B7/12 B32B5/02 B32B15/04 B32B27/06 

FIELD: chemistry.

SUBSTANCE: invention relates to packaging and method of producing multilayer film. Film contains, at least, two layers connected by means of solvent-free two-component glue, including the following stages: applying a first component A of the two-component adhesive onto a first side of the first film layer; applying a second component B of the two-component adhesive onto a first side of the second film layer; bringing the first and second sides of the first and second layers into mutual contact, allowing to connect components (A) and (B), to obtain an adhesive and joining two layers in the multilayer film (M); and winding produced multilayer film on drum.

EFFECT: invention provides technological effectiveness of the process of producing a multilayer film for packaging with improved optical properties.
