真(zhen)(zhen)(zhen)空(kong)(kong)包(bao)裝機按照抽(chou)氣方(fang)式不同會有內抽(chou)式和外抽(chou)式兩種(zhong)類型(xing)，它們都是由真(zhen)(zhen)(zhen)空(kong)(kong)系(xi)統、抽(chou)充氣密封系(xi)統、熱(re)壓封合系(xi)統、電(dian)器(qi)控制(zhi)系(xi)統等組成(cheng)。其(qi)中內抽(chou)式包(bao)裝機是有真(zhen)(zhen)(zhen)空(kong)(kong)室(shi)的，物(wu)品可(ke)以擺(bai)放在(zai)真(zhen)(zhen)(zhen)空(kong)(kong)室(shi)里，合上真(zhen)(zhen)(zhen)空(kong)(kong)機的真(zhen)(zhen)(zhen)空(kong)(kong)室(shi)上蓋后，就形(xing)成(cheng)密閉的空(kong)(kong)間，這樣就可(ke)以進行抽(chou)真(zhen)(zhen)(zhen)空(kong)(kong)工(gong)作了，但是在(zai)工(gong)作過程(cheng)中，有時會出現真(zhen)(zhen)(zhen)空(kong)(kong)蓋合不上的情況
