Document Type and Number:
WIPO Patent Application WO/2017/116106
Kind Code:
A1
Abstract:
The present invention relates to a barrier film and, more particularly, to a plastic nano composite film in which clay (clay tablets) particles are dispersed, a process for bonding a metal film or sheet to the plastic nano composite film without using an adhesive, and the manufacture of a high moisture- and gas-barrier flexible film formed into a multilayer structure of an organic composite-metal or (organic composite-metal-organic composite) film manufactured by the process. The high moisture- and gas-barrier flexible film according to the present invention causes a chemical reaction or exhibits a polar interaction between a matrix resin of a nanocomposite and a reactive group of having a metal surface, such that a metal film and the nanocomposite are uniformly bonded to the entire area, thereby removing a space for gas and moisture to penetrate therethrough.
