MULTILAYER PACKAGING MATERIAL Russian patent published in 2012 - IPC B32B27/04 B32B15/12 C09J125/08 

FIELD: manufacturing process.

SUBSTANCE: invention relates to manufacture of flexible multilayer packaging materials for food products, particularly to multilayer material comprising layers of aluminuim foil and fat- and water-proof paper. The multilayer packaging material comprises as an adhesive for joining layers of aluminuim foil and fat- and water-proof paper an adhesive composition based on an aqueous dispersion of a copolymer of acrylic acid ester and styrene. The composition also includes a coalescent additive - isomeric mixture of 2,2,4-trimethyl-1,3-pentadiol-monoisobutyran, antiseptic - a composition of tri-n-butyltin naphthenate with nitrogen organic compound, antifoam based on mineral oil, a thickening agent - sodium salt of carboxymethyl cellulose and distilled water.

EFFECT: increased adhesive bond strength of multilayer packaging material, the material resistance to multiple excesses, produceability.
