GAS BARRIER FILM, GAS BARRIER LAMINATE AND METHOD FOR PRODUCTION OF THE FILM OR LAMINATE |
摘要 |
<p>Disclosed is an excellent gas barrier laminate whose gas-barrier property has little dependency on temperature and which hardly causes fracture even when the laminate is stretched. A gas barrier film comprising a polymer (A) of an unsaturated carboxylic acid compound monovalent metal salt (a), wherein the polymer (A) contains a modified vinyl alcohol polymer (B); a gas barrier laminate comprising a base layer and the gas barrier film formed on at least one surface of the base layer; and a method for production of a gas barrier laminate comprising the steps of: coating a solution of an unsaturated carboxylic acid compound monovalent metal salt (a) having a polymerization degree less than 20 on at least one surface of a base layer, wherein the solution contains a modified vinyl alcohol polymer (B); performing the polymerization to form a layer of the polymer (A) of the unsaturated carboxylic acid compound monovalent metal salt (a) containing the modified vinyl alcohol polymer (B).</p> |
