FIELD: technological processes.
SUBSTANCE: mixtures of recycled PET, which is not polymerized in hard state, with PEN and/or NDK in amount less than around 10 wt %, are used in at least one layer of item, such as container or previously molded stock for blow forming of container, having internal layer of thermoplastic material.
EFFECT: invention makes it possible, having added small amount of PEN and/or NDK, to directly use recycled PET without its polymerisation in hard state and provides for production of items, having resistance to cracking in process of stretching under effect of environment, colour and organoleptic properties, comparable to similar properties of PET that was not used.
