FIELD: textile industry. SUBSTANCE: invention relates to film multilayer polymer materials suitable for manufacturing tent materials utilized when constructing stalls, sheds, cornices, fast-constructed tent structures bearing no large loads. Material, in particular, contains intermediate calico-weave polyester fabric layer and two-side polyvinylchloride coating and is distinguished by that polyester fabric is manufactured from threads with linear density 15.6 to 36.2 tex and numbers of threads per 10 cm 130-280 for warp and 120-260 for weft. Weight ratio of polyester fabric to polyvinylchloride coating ranges from 1:2.8 to 1:4. EFFECT: reduced surface weight and enabled deep diffusion of polyvinylchloride into fabric thereby ensuring strong joining between coating and base material. 1 dwg, 1 tbl, 3 ex
