FIELD: textile, paper.
SUBSTANCE: material is produced by method of polymer melt blowing. Layers are made of propylene copolymer with crystallinity that makes less than 50%. Layers have maximum value of stretching force (Fmd) in longitudinal direction per 1 inch of width normalised by density of 20g/m2, characterised with the following equations: a) Fmd ≥ [-0,00143×relative extension (%)+ 0.823], if relative extension is between 20 and 675%; b) Fmd≥0.1 pound, if relative extension is more or equal to 675%. Laminate structures contain at least one layer of nonwoven material "spunbond".
EFFECT: structures have combination of low value bending module with high value of flaking resistance.
