FIELD: manufacturing processes.
SUBSTANCE: invention relates to a container with improved gas-barrier properties. Multilayer moulded container with blow and extension comprises at least two outer layers containing the polymer matrix. The polymer matrix contains polyester, polyamide, polyolefin, polyimide, polylactide, or their derivatives. Multilayer moulded container with blow and extension comprises at least one barrier layer disposed between at least two outer layers. One barrier layer comprises the first polymer composition comprising a polymer matrix and low molecular weight additive improving gas-barrier properties. A low-molecular additive is a purine derivative having a molecular weight less than 1000 daltons.
EFFECT: increased shelf life of the contents of the container.
