GAS BARRIER FILM AND METHOD FOR PRODUCING GAS BARRIER FILM

摘要

Provided is a laminated gas barrier film which has outstanding optical characteristics while having adequate gas barrier properties, and has excellent producibility. The gas barrier film comprises on at least one surface of a base material an inorganic layer which is formed by means of vacuum deposition, the inorganic layer which is formed by means of vacuum deposition being formed by using heat to vaporize a vaporization material that is formed by sintering and moulding an inorganic powder having a median diameter of 3-100 µm into a cylindrical shape whereof the diameter is 10-45% of the inner diameter at the bottom part of a crucible and the height is no greater than 45% of the internal height of the crucible.
