The express-method of diagnostics and selection of polymeric petroleum products is substantiated. Such products are processed by hot melt extrusion into films with technical purposes and then used in packaging. Bright visual effects in layers of polyolefin film materials are used in packaging of consumer goods; they can be seen in polarized light and depend on chemical and phase composition of films. For films application in smart packaging, for example, frozen food products, input control and diagnostics is required not only of mechanical and optical properties, but also of sensitivity of their optical properties to heat treatment. The two-stage method is suggested for checking the suitability of polyolefin films for the latent marking in polarized light for their usage in the production of intelligent packaging for frozen foods or other products with a strictly regulated mode of storage.
