FIELD: transport.
SUBSTANCE: method for manufacturing multilayer thermoformed polymeric packaging film includes operation of polygraphic image printing on two-axis-oriented film, its combination with polymeric substrate film so that the mentioned image is located between the mentioned films, and subsequent hot shaping of multilayer film. The image is printed in inverse direction, and two-axis-oriented film is used with thickness determined from condition that for each 10.0 mm of drawing depth during hot shaping, two-axis-oriented film structure thickness of 0.007 mm to 0.02 mm is provided.
EFFECT: perfected method.
