Coated polyester film and polyester/polyolefin laminates produced therefrom

摘要: A coated polyester film suitable for producing polyester/ polyolefin laminates consists of biaxially oriented poly(ethylene terephthalate) with a cross-linked styrene copolymer by deposition from an aqueous coating composition which comprises (A) containing 50-75 mole % units and 25-50 comonomer providing carboxylic groups (10-50 %) alkyl carboxylate (20-50 (B) melamine/formaldehyde cross-linking agent. The is preferably water-soluble maleic anhydride partially converted into butyl ester neutralized ammonia, the agent conveniently hexamethoxymethylmelamine. layer in produced may particular be low-density polyethylene.
