Beschreibung
Zusammenfassung:	Provided is a high-barrier film having both flexibility and high-barrier property, the high-barrier film being usable as a packaging material for pharmaceutical products, or a flexible sealing material. The transparent high-barrier film of the present invention is a transparent barrier film including a plastic film, and at least a barrier layer is stacked on the plastic film, the transparent barrier film satisfying all of the following requirements (A) to (C): (A) the barrier layer is a layer in which two or more units are stacked, each unit having a structure in which a barrier layer A, a barrier layer B and a barrier layer A are stacked in this order; (B) the barrier layer A is a layer composed of SiOC in which the content ratio of carbon quantitatively analyzed by XPS is in a range of more than 0% and less than 15%; and (C) the barrier layer B is a layer composed of SiOC in which the content ratio of carbon quantitatively analyzed by XPS is in a range of 1.1 to 4.0 times the content ratio of carbon in the barrier layer A.
