真空(kong)(kong)(kong)包(bao)裝(zhuang)機(ji)按(an)照抽(chou)氣方式(shi)不(bu)同會有(you)內抽(chou)式(shi)和外抽(chou)式(shi)兩(liang)種(zhong)類型，它們都是由真空(kong)(kong)(kong)系(xi)(xi)統、抽(chou)充氣密(mi)封(feng)系(xi)(xi)統、熱壓(ya)封(feng)合系(xi)(xi)統、電器控制系(xi)(xi)統等組成。其中內抽(chou)式(shi)包(bao)裝(zhuang)機(ji)是有(you)真空(kong)(kong)(kong)室的，物品可以擺放在真空(kong)(kong)(kong)室里，合上真空(kong)(kong)(kong)機(ji)的真空(kong)(kong)(kong)室上蓋后，就形成密(mi)閉(bi)的空(kong)(kong)(kong)間(jian)，這樣(yang)就可以進行抽(chou)真空(kong)(kong)(kong)工(gong)作(zuo)了，但是在工(gong)作(zuo)過程(cheng)中，有(you)時會出現真空(kong)(kong)(kong)蓋合不(bu)上的情況
