真(zhen)(zhen)空(kong)(kong)包(bao)裝機(ji)按(an)照抽(chou)氣方式不同會有內抽(chou)式和外抽(chou)式兩種類型，它(ta)們都(dou)是由真(zhen)(zhen)空(kong)(kong)系(xi)(xi)統(tong)、抽(chou)充氣密封(feng)系(xi)(xi)統(tong)、熱壓(ya)封(feng)合系(xi)(xi)統(tong)、電器(qi)控制(zhi)系(xi)(xi)統(tong)等(deng)組成(cheng)。其中(zhong)內抽(chou)式包(bao)裝機(ji)是有真(zhen)(zhen)空(kong)(kong)室(shi)的(de)，物品(pin)可(ke)以擺(bai)放在真(zhen)(zhen)空(kong)(kong)室(shi)里，合上真(zhen)(zhen)空(kong)(kong)機(ji)的(de)真(zhen)(zhen)空(kong)(kong)室(shi)上蓋(gai)(gai)后，就形(xing)成(cheng)密閉的(de)空(kong)(kong)間，這樣(yang)就可(ke)以進行抽(chou)真(zhen)(zhen)空(kong)(kong)工(gong)作了，但是在工(gong)作過程(cheng)中(zhong)，有時會出現真(zhen)(zhen)空(kong)(kong)蓋(gai)(gai)合不上的(de)情況(kuang)
