A fluid enveloping device includes a housing having a vacuum chamber; a valve for blocking off the communication of the vacuum chamber and atmospheric environment; a vacuum pump module connected to the vacuum chamber for extracting air until the vacuum chamber is close to a vacuum state; a die holder for locating a lower thin film and receiving the fluid at the lower thin film; a punch holder for locating an upper thin film; and a sealing nip in the vacuum chamber for hot-pressing the upper and the lower thin films to envelope the fluid therein.
