RADIATION CURABLE AQUEOUS COMPOSITIONS FOR LOW EXTRACTABLE FILM PACKAGING

摘要

A method for producing a low-extractable film packaging from an actinic radiation curable homogeneous aqueous composition containing a water soluble compound having at least one alpha, beta-ethylenically unsatured, radiation polymerizable group and water as essential components carried out by applying the aqueous composition to a surface which is then irradiated with actinic radiation in the presence of the water thereby forming a cured film wherein less than 50 ppb of the water soluble compound or its residual components are extractable by a food simulant.
