真(zhen)(zhen)空(kong)(kong)(kong)包(bao)裝機(ji)按照抽(chou)(chou)氣(qi)方式(shi)不同會有(you)內抽(chou)(chou)式(shi)和外抽(chou)(chou)式(shi)兩種類(lei)型，它們都是(shi)由(you)真(zhen)(zhen)空(kong)(kong)(kong)系(xi)統、抽(chou)(chou)充氣(qi)密封系(xi)統、熱壓封合系(xi)統、電器控制系(xi)統等組成。其中內抽(chou)(chou)式(shi)包(bao)裝機(ji)是(shi)有(you)真(zhen)(zhen)空(kong)(kong)(kong)室(shi)的(de)，物品(pin)可(ke)以(yi)擺放在真(zhen)(zhen)空(kong)(kong)(kong)室(shi)里，合上真(zhen)(zhen)空(kong)(kong)(kong)機(ji)的(de)真(zhen)(zhen)空(kong)(kong)(kong)室(shi)上蓋后，就(jiu)形成密閉的(de)空(kong)(kong)(kong)間，這樣就(jiu)可(ke)以(yi)進行抽(chou)(chou)真(zhen)(zhen)空(kong)(kong)(kong)工(gong)作了，但是(shi)在工(gong)作過程中，有(you)時會出現真(zhen)(zhen)空(kong)(kong)(kong)蓋合不上的(de)情況
