FILM MEMBER AND LIQUID EJECTING APPARATUS

摘要

A film member includes an inside film layer which is disposed on a surface in contact with liquid; an outside film layer which is disposed on the opposite side to the surface of the inside film layer in contact with the liquid; and a junction layer which is disposed between the inside film layer and the outside film layer to join the inside film layer and the outside film layer, in which an SP value (here, the SP value represents a solubility parameter value) of a resin material which forms the junction layer is equal to or larger than an SP value of a resin material that forms the inside film layer, and an SP value of a resin material that forms the outside film layer is equal to or larger than the SP value of the resin material that forms the inside film layer.

主权项

1. A film member which is used in a portion in contact with liquid in a liquid ejecting apparatus, comprising:
an inside film layer which is disposed on a surface in contact with the liquid; an outside film layer which is disposed on the opposite side to the surface of the inside film layer in contact with the liquid; and a junction layer which is disposed between the inside film layer and the outside film layer to join the inside film layer and the outside film layer, wherein an SP value (here, the SP value represents a solubility parameter value) of a resin material which forms the junction layer is equal to or larger than an SP value of a resin material that forms the inside film layer, and an SP value of a resin material that forms the outside film layer is equal to or larger than the SP value of the resin material that forms the inside film layer.
