真空(kong)(kong)包(bao)裝機按照抽(chou)(chou)氣方式(shi)(shi)不同(tong)會有(you)內抽(chou)(chou)式(shi)(shi)和外抽(chou)(chou)式(shi)(shi)兩種類型，它們(men)都是由(you)真空(kong)(kong)系(xi)(xi)統(tong)、抽(chou)(chou)充(chong)氣密(mi)封系(xi)(xi)統(tong)、熱(re)壓封合(he)系(xi)(xi)統(tong)、電器控制系(xi)(xi)統(tong)等組成(cheng)。其中內抽(chou)(chou)式(shi)(shi)包(bao)裝機是有(you)真空(kong)(kong)室的(de)，物品(pin)可(ke)(ke)以擺放在真空(kong)(kong)室里，合(he)上真空(kong)(kong)機的(de)真空(kong)(kong)室上蓋(gai)后，就(jiu)(jiu)形(xing)成(cheng)密(mi)閉(bi)的(de)空(kong)(kong)間，這樣就(jiu)(jiu)可(ke)(ke)以進行抽(chou)(chou)真空(kong)(kong)工(gong)作了，但是在工(gong)作過程(cheng)中，有(you)時會出現真空(kong)(kong)蓋(gai)合(he)不上的(de)情(qing)況(kuang)
