真(zhen)空(kong)(kong)(kong)包(bao)裝(zhuang)機按照抽(chou)氣方式不(bu)同會有(you)(you)內(nei)抽(chou)式和外抽(chou)式兩種類型，它(ta)們都是由真(zhen)空(kong)(kong)(kong)系統、抽(chou)充(chong)氣密封(feng)系統、熱壓(ya)封(feng)合系統、電器控制系統等組成。其中內(nei)抽(chou)式包(bao)裝(zhuang)機是有(you)(you)真(zhen)空(kong)(kong)(kong)室的(de)，物品(pin)可以擺放在真(zhen)空(kong)(kong)(kong)室里，合上真(zhen)空(kong)(kong)(kong)機的(de)真(zhen)空(kong)(kong)(kong)室上蓋(gai)后(hou)，就形成密閉(bi)的(de)空(kong)(kong)(kong)間，這樣就可以進行抽(chou)真(zhen)空(kong)(kong)(kong)工作了，但是在工作過程中，有(you)(you)時會出現真(zhen)空(kong)(kong)(kong)蓋(gai)合不(bu)上的(de)情況
