Document Type and Number:
Japanese Patent JP2014124948
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a film member capable of effectively preventing the bulging of the film member caused by staying of solvents of a liquid infiltrated from a surface in contact with the liquid of the film member made of a laminate body, and a liquid injection device.SOLUTION: A film member 44 comprises: an inner film layer 61; an adhesive layer 62; a gas barrier layer 63; and an outer film layer 64, each of which is stacked in order from the surface of a side in contact with ink as an example of liquid. The SP value of the resin material of the outer film layer 64 is equal to or higher than that of the resin material of the inner film layer 61. A difference between the SP value of the resin material configuring the adhesive layer 62 and the SP value of the resin material configuring the outer film layer 64 is smaller than that between the SP value of the resin material configuring the adhesive layer 62 and the SP value of the resin material configuring the inner film layer 61.
