GAS-BARRIER FILM AND GAS-BARRIER COATING AGENT, AND METHOD FOR PRODUCTION THEREOF |
摘要 |
<p>Provided are a gas-barrier film which is a laminate comprising a substrate layer comprising a thermoplastic resin film and a gas-barrier layer comprising a hydrolysate of a silicon alkoxide, a stratified silicate and a polyvinyl alcohol base resin, wherein a radius (Rg) of gyration of a scattering matter which is measured by light scattering in the gas-barrier layer described above is 2.4 mu m or less, and the silicon alkoxide and/or the hydrolysate thereof are present between the layers of the stratified silicate present in the above gas-barrier layer. The above film shows an excellent gas-barrier property even under such a high humidity as exceeding 90 % RH. <IMAGE></p> |
