FIELD: packaging industry.
SUBSTANCE: invention relates to multilayer packaging materials and relates to the coated woven material and the bag made of this material. It comprises the fabric of polymeric tapes. The fabric is coated with sealing layer. Part of the polymeric tapes has the tensile capacity which is less than 45 cN/tex and tensile elongation of more than 30%. The sealing layer is formed from a composition comprising at least one copolymer of ethylene/α-olefin, at that the composition has the density of from 0.905 to 0.930 g/cm3 and the melt flow index of from 3 to 20 g/10 min. The bag comprises the said fabric. The walls of the bag are at least partially composed of the woven material of polymeric tapes, at that each of the edges of the bag walls is provided with a neck for filling.
EFFECT: invention enables to produce the coated woven material, which provides reliable sealing without thick and expensive sealing layers.
