LASER-WELDED SEALED PACKAGE AND SEALING METHOD THEREFOR |
摘要 |
Disclosed are packages that comprise laminated materials, and sealed packages comprising sealing members that hermetically seal said packages. Said laminated materials comprise a base material layer, a thermoplastic resin layer containing iron powder, and a thermoplastic resin layer that transmits laser beams, and at least the surface of said sealing member that contacts the package is made of thermoplastic resin that can transmit laser beams. By the contact surfaces of said package and sealing member being hermetically sealed by laser welding, laser welding can be performed effectively utilizing the iron powder that has conventionally been effectively used as an oxygen absorber in packaging containers. |
