| abstract |
This invention relates to gas barrier coatings. The present invention discloses water dilutable coating compositions comprising polyvinyl alcohol and/or ethylene-vinyl alcohol copolymers, dispersed clay and polycarboxylic acid polymers which can be prepared using conventional equipment And when incorporated into adhesively formed laminates, especially PET-PE laminate structures, the coating composition provides excellent oxygen barrier properties at high relative humidity as well as good lamination bond strength . |
