真空(kong)(kong)(kong)包(bao)裝(zhuang)機(ji)按照抽(chou)氣(qi)方式不(bu)同會有內(nei)抽(chou)式和外抽(chou)式兩種類型，它們都(dou)是由真空(kong)(kong)(kong)系統、抽(chou)充氣(qi)密封(feng)系統、熱壓封(feng)合系統、電器控(kong)制系統等組成(cheng)。其中(zhong)(zhong)內(nei)抽(chou)式包(bao)裝(zhuang)機(ji)是有真空(kong)(kong)(kong)室的(de)，物品可(ke)以(yi)擺放在(zai)(zai)真空(kong)(kong)(kong)室里，合上真空(kong)(kong)(kong)機(ji)的(de)真空(kong)(kong)(kong)室上蓋后，就形成(cheng)密閉的(de)空(kong)(kong)(kong)間，這樣就可(ke)以(yi)進行抽(chou)真空(kong)(kong)(kong)工作(zuo)了，但是在(zai)(zai)工作(zuo)過程(cheng)中(zhong)(zhong)，有時會出現真空(kong)(kong)(kong)蓋合不(bu)上的(de)情況
