FIELD: manufacturing technology.
SUBSTANCE: group of inventions relates to a method of making a thermally deformable polymer film of at least two-color design, a system for making thermally deformable polymer film of at least two-color design, as well as thermally deformable polymer film of at least two-color design. Method includes steps of: first polymer extrusion to produce molten-liquid polymer melt and planar application of said polymer melt from first polymer with first thickness by means of extrusion nozzle/wide slit nozzle. Then, a certain planar application of the second dispersed and/or loose polymer is carried out in a certain pattern design by means of a pattern template on a polymer melt consisting of a first polymer. Then calendering/calibrating of polymer melt thickness and simultaneous at least partial indentation of plane patterned in design of second polymer pattern into first polymer by means of calender system and cooling of melt to produce solid polymer film. System for making thermally deformable polymer film of at least two-color design comprises devices for realizing the method according to the invention and obtaining a thermally deformable polymer film of at least two-color design.
EFFECT: providing an optimum and efficient method of making a film.
