FIELD: chemistry.
SUBSTANCE: composite sheet material comprises a laminate structure with the following layers: optional thermoplastic material layer; a carrier layer; the first layer of thermoplastic material KSv; a barrier layer; the second layer of thermoplastic material KSa; at least one additional layer of thermoplastic material KSw; wherein the Vicat softening temperature of the thermoplastic material layer KSv and Vicat softening temperature of the thermoplastic material layer KSa in each case is above the Vicat softening temperature of the thermoplastic material layer KSw. The invention also includes a method for production of sheet composite, a container which includes an inner cavity and comprises at least one such sheet composite material and a method for production of such a container, comprising the steps of sheet composite material provision with a laminate structure described above, folding, coupling and possibly filling and possibly closing of the container obtained in such manner.
EFFECT: obtaining of sheet composite material with improved impermeability against vapor and oxygen coupled with good workability and high reliability, in particular, it does not form defects, and is suitable for manufacture of containers for transportation and storage of milk, dairy products, beverages, containing vitamin C, and other beverages, foods, drinks with a low content of carbon dioxide or animal food.
