真空(kong)(kong)包裝機(ji)按照(zhao)抽(chou)氣方式(shi)不(bu)(bu)同會有內(nei)抽(chou)式(shi)和外(wai)抽(chou)式(shi)兩種類型，它們都是(shi)由真空(kong)(kong)系(xi)統(tong)、抽(chou)充氣密(mi)封系(xi)統(tong)、熱壓封合系(xi)統(tong)、電器控制(zhi)系(xi)統(tong)等組成(cheng)。其中內(nei)抽(chou)式(shi)包裝機(ji)是(shi)有真空(kong)(kong)室的(de)(de)(de)，物(wu)品可以(yi)擺(bai)放在(zai)真空(kong)(kong)室里，合上真空(kong)(kong)機(ji)的(de)(de)(de)真空(kong)(kong)室上蓋后，就形成(cheng)密(mi)閉的(de)(de)(de)空(kong)(kong)間(jian)，這樣就可以(yi)進行抽(chou)真空(kong)(kong)工(gong)作了，但(dan)是(shi)在(zai)工(gong)作過程中，有時會出現真空(kong)(kong)蓋合不(bu)(bu)上的(de)(de)(de)情況
