真(zhen)(zhen)(zhen)空(kong)(kong)包(bao)裝(zhuang)機按照抽(chou)氣方式不(bu)同會有內(nei)抽(chou)式和(he)外抽(chou)式兩種(zhong)類型(xing)，它們(men)都是由(you)真(zhen)(zhen)(zhen)空(kong)(kong)系(xi)(xi)統(tong)、抽(chou)充氣密封系(xi)(xi)統(tong)、熱壓封合(he)系(xi)(xi)統(tong)、電器控制(zhi)系(xi)(xi)統(tong)等(deng)組成。其(qi)中內(nei)抽(chou)式包(bao)裝(zhuang)機是有真(zhen)(zhen)(zhen)空(kong)(kong)室的，物品(pin)可以擺(bai)放在真(zhen)(zhen)(zhen)空(kong)(kong)室里，合(he)上(shang)(shang)真(zhen)(zhen)(zhen)空(kong)(kong)機的真(zhen)(zhen)(zhen)空(kong)(kong)室上(shang)(shang)蓋后，就形成密閉(bi)的空(kong)(kong)間，這樣就可以進行抽(chou)真(zhen)(zhen)(zhen)空(kong)(kong)工作了，但(dan)是在工作過(guo)程中，有時會出現真(zhen)(zhen)(zhen)空(kong)(kong)蓋合(he)不(bu)上(shang)(shang)的情況
