INTERMEDIATE FILM FOR MULTILAYER GLASS, ROLLED ARTICLE, MULTILAYER GLASS, METHOD OF PRODUCING INTERMEDIATE FILM FOR MULTILAYER GLASS AND METHOD OF PRODUCING ROLLED ARTICLE Russian patent published in 2019 - IPC C03C27/12 B32B3/30 

FIELD: glass.

SUBSTANCE: invention relates to an interlayer film for laminated glass. Film has multiple recesses and multiple bulges on at least one surface. Film has such thickness that the difference between the maximum thickness and the minimum thickness is less than 40 mcm in each of the central part, one edge part and the other edge part in the transverse direction, which is perpendicular, in relation to the machine direction of the film during its manufacturing. Thickness is measured during 3 m in film machine direction during its manufacturing.

EFFECT: technical result is higher degree of deaeration during preliminary connection under pressure and providing high transparency of multilayer glass.
