真(zhen)(zhen)空(kong)(kong)包(bao)裝機(ji)(ji)按照(zhao)抽(chou)氣方式(shi)不同會有內抽(chou)式(shi)和外抽(chou)式(shi)兩種類(lei)型，它們都(dou)是由真(zhen)(zhen)空(kong)(kong)系統(tong)(tong)、抽(chou)充氣密封(feng)系統(tong)(tong)、熱壓(ya)封(feng)合系統(tong)(tong)、電器(qi)控制(zhi)系統(tong)(tong)等組成(cheng)(cheng)。其中內抽(chou)式(shi)包(bao)裝機(ji)(ji)是有真(zhen)(zhen)空(kong)(kong)室(shi)的(de)(de)，物品可(ke)以擺放在真(zhen)(zhen)空(kong)(kong)室(shi)里，合上(shang)真(zhen)(zhen)空(kong)(kong)機(ji)(ji)的(de)(de)真(zhen)(zhen)空(kong)(kong)室(shi)上(shang)蓋后，就形(xing)成(cheng)(cheng)密閉的(de)(de)空(kong)(kong)間(jian)，這樣就可(ke)以進行抽(chou)真(zhen)(zhen)空(kong)(kong)工(gong)(gong)作(zuo)了(le)，但是在工(gong)(gong)作(zuo)過程中，有時會出現真(zhen)(zhen)空(kong)(kong)蓋合不上(shang)的(de)(de)情況(kuang)
