真空(kong)(kong)包裝機按照抽(chou)(chou)(chou)氣(qi)方(fang)式(shi)(shi)不(bu)同會有內抽(chou)(chou)(chou)式(shi)(shi)和外(wai)抽(chou)(chou)(chou)式(shi)(shi)兩(liang)種類型(xing)，它們都是由真空(kong)(kong)系統(tong)、抽(chou)(chou)(chou)充氣(qi)密封(feng)系統(tong)、熱壓封(feng)合系統(tong)、電器控制(zhi)系統(tong)等組(zu)成。其中內抽(chou)(chou)(chou)式(shi)(shi)包裝機是有真空(kong)(kong)室的，物品可以擺放在真空(kong)(kong)室里，合上(shang)真空(kong)(kong)機的真空(kong)(kong)室上(shang)蓋(gai)后，就形成密閉(bi)的空(kong)(kong)間，這樣就可以進行抽(chou)(chou)(chou)真空(kong)(kong)工作(zuo)了，但(dan)是在工作(zuo)過(guo)程中，有時會出(chu)現真空(kong)(kong)蓋(gai)合不(bu)上(shang)的情(qing)況
