  • Laminated film-packed hard disk drive for hermetic sealing
    Patent number: 9570114
    Abstract: A hermetically-sealed hard disk drive (HDD) utilizes a laminated film enclosure to hermetically seal an HDD within. The laminated film enclosure may be constructed of a heat sealant layer hermetically-sealed around the HDD, a barrier layer which inhibits gas from escaping from inside the laminated film enclosure, and a film surface protective layer which protects the heat sealant and barrier layers. Embodiments may include a heat sealant layer comprising a thermoplastic polymer such as polypropylene, a barrier layer comprising a metal such as aluminum, and a film surface protective layer comprising a thermoplastic polymer such as polyethylene terephthalate.
