FIELD: technological processes.
SUBSTANCE: laminate plastic contains single-film or multi-film layer A and one more single-film or multi-film layer B, at that both layers mainly consist of oriented thermoplastic polymer material, at that layer A has corrugated configuration, and layer B on the first side is fastened with glue in zones of fastening with combs on the first side of layer A, at that layer B also has corrugated configuration, direction of corrugations in layer B creates angle mostly from 30° to 90° inclusive with direction of layer A corrugations. Mentioned fastening zones are located in combs of the first side of layer B for provision of point fastening with combs on the first side of layer A, lengths of corrugation waves in layer A and/or layer B do not exceed 5 mm, and lengths of corrugation waves in both layers A and B are less than 10 mm.
EFFECT: material has high yield point and stretching resistance.
