METHOD OF FILM STRETCHING Russian patent published in 2017 - IPC B29C55/06 B29D7/00 A61F13/15 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to laminated material producing method containing non-woven fabric and film. This method comprises heating initial thermoplastic polymer material film, containing at least one low-melting polymer component and at least one high-melting polymer component, until at least partially melted state. At that, at least one low-melting polymer component is in melted liquid state, and at least one high-melting polymer component is not in melted liquid state. Melting is performed by means of at least one heating cylinder. Then performing cooled by passing of partially melted film via cooled cylinders clamp. Film is stretched between at least one heating cylinder and cooled cylinders clamp. Produced films can be laminated together with nonwoven material. Laminated material is used in medicine or hygiene fields.

EFFECT: technical result achieved when using method and laminated material according to inventions, consists in production of thinner films.
