FIELD: chemistry.
SUBSTANCE: invention relates to a film consisting of a mixture of a polyvinyl chloride polymer, a polyester and additives, thermoformed articles and a method of producing the film. The film from a mixture of vinyl chloride polymers includes 70-97 wt % of one or more vinyl chloride polymers with a coefficient K of 50-90, 2-25 wt % of additives selected from a group consisting of modifiers, high-molecular weight polymers, stabilisers, waxes, polymer anticaking agents, dye substances, plasticisers, auxiliary agents for improving processability and 0.1 wt % to less than 5 wt % polycrystalline or amorphous polyester with a crystallisation half-period in molten state of less than 5 min with respect to the total weight of the mixture of vinyl chloride polymers. The film is obtained by extruding or calendaring a plasticised mixture of vinyl chloride polymers, followed by optional treating in a built-in or self-contained process and optional thermoforming.
EFFECT: film has good thermoforming capacity and is suitable for packaging mass-production items.
