真(zhen)空(kong)(kong)(kong)包(bao)裝機(ji)(ji)按照抽(chou)氣方式不同會(hui)有內抽(chou)式和外抽(chou)式兩種類(lei)型，它們都(dou)是由真(zhen)空(kong)(kong)(kong)系(xi)統(tong)、抽(chou)充氣密封系(xi)統(tong)、熱壓封合系(xi)統(tong)、電(dian)器控制系(xi)統(tong)等組成。其中內抽(chou)式包(bao)裝機(ji)(ji)是有真(zhen)空(kong)(kong)(kong)室的(de)，物品可以(yi)擺放(fang)在真(zhen)空(kong)(kong)(kong)室里，合上真(zhen)空(kong)(kong)(kong)機(ji)(ji)的(de)真(zhen)空(kong)(kong)(kong)室上蓋(gai)(gai)后，就(jiu)形成密閉的(de)空(kong)(kong)(kong)間，這樣就(jiu)可以(yi)進行抽(chou)真(zhen)空(kong)(kong)(kong)工(gong)作了，但是在工(gong)作過(guo)程中，有時會(hui)出現真(zhen)空(kong)(kong)(kong)蓋(gai)(gai)合不上的(de)情況
