真空(kong)(kong)包裝機(ji)按照抽(chou)氣(qi)方(fang)式(shi)不(bu)同會有(you)內(nei)抽(chou)式(shi)和外抽(chou)式(shi)兩種(zhong)類(lei)型，它們都是(shi)由真空(kong)(kong)系(xi)(xi)統、抽(chou)充(chong)氣(qi)密(mi)封(feng)(feng)系(xi)(xi)統、熱壓封(feng)(feng)合系(xi)(xi)統、電器控制系(xi)(xi)統等組成。其中(zhong)內(nei)抽(chou)式(shi)包裝機(ji)是(shi)有(you)真空(kong)(kong)室(shi)的(de)(de)，物(wu)品(pin)可以擺放在真空(kong)(kong)室(shi)里，合上(shang)真空(kong)(kong)機(ji)的(de)(de)真空(kong)(kong)室(shi)上(shang)蓋后，就形(xing)成密(mi)閉的(de)(de)空(kong)(kong)間，這(zhe)樣就可以進(jin)行抽(chou)真空(kong)(kong)工作了，但(dan)是(shi)在工作過程中(zhong)，有(you)時會出(chu)現(xian)真空(kong)(kong)蓋合不(bu)上(shang)的(de)(de)情況(kuang)
