真(zhen)(zhen)(zhen)空(kong)包(bao)裝機按照(zhao)抽氣方式(shi)不(bu)同(tong)會(hui)有內抽式(shi)和外抽式(shi)兩(liang)種(zhong)類型，它們都是由真(zhen)(zhen)(zhen)空(kong)系統(tong)(tong)、抽充氣密(mi)封系統(tong)(tong)、熱壓(ya)封合系統(tong)(tong)、電器控制系統(tong)(tong)等組成(cheng)。其中內抽式(shi)包(bao)裝機是有真(zhen)(zhen)(zhen)空(kong)室的，物品可(ke)以(yi)擺放在(zai)真(zhen)(zhen)(zhen)空(kong)室里，合上(shang)真(zhen)(zhen)(zhen)空(kong)機的真(zhen)(zhen)(zhen)空(kong)室上(shang)蓋(gai)后(hou)，就形(xing)成(cheng)密(mi)閉的空(kong)間(jian)，這樣就可(ke)以(yi)進行抽真(zhen)(zhen)(zhen)空(kong)工作了，但是在(zai)工作過程中，有時會(hui)出現真(zhen)(zhen)(zhen)空(kong)蓋(gai)合不(bu)上(shang)的情況
