Title:
POLYVINYL ALCOHOL VAPOR-DEPOSITED FILM
Document Type and Number:
WIPO Patent Application WO/2013/125564
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a vapor-deposited film with which it is possible to suppress the formation of pinholes and cracks due to bending during vapor-deposited film processing such as lamination, and thus prevent a reduction in the gas barrier property. The present invention is a vapor-deposited film comprising a base film that includes a polyvinyl alcohol copolymer, and a metal vapor-deposited layer laminated on the base film, said vapor-deposited film being characterized in that the average particle diameter is 150 nm or less as measured at the metal vapor-deposited layer using an electron microscope. The average thickness of the metal vapor-deposited layer is preferably 30 nm to 100 nm.
