EXTRUSION GLUED LAMINATES FOR ABSORBENT PRODUCTS Russian patent published in 2013 - IPC A61F13/15 

FIELD: medicine.

SUBSTANCE: invention refers to absorbent products that may include an upper layer, an outer coating and an absorbent body located between the upper layer and the outer coating. The outer coating comprises an extrusion glued laminate (EGL). The EGL may comprise a multilayer coextruded elastic film and a nonwoven material. The elastic film may comprise a first outer layer, a second outer layer and a central layer between the first and second outer layers. The nonwoven material may comprise fibres or filaments. The first outer layer may be non-adhesive coupled to the nonwoven material by extrusion. Further, the outer coating can retain the elasticity of at least 50% relative deformation. The first outer layer can have a low affinity for the central layer. The first outer layer can comprise an extended polymer in an amount exceeding 45 wt %.

EFFECT: nonwoven material can have a high affinity for the first outer layer.
