真(zhen)(zhen)空(kong)(kong)(kong)包(bao)裝機按照抽(chou)氣方(fang)式(shi)不同(tong)會有內抽(chou)式(shi)和(he)外抽(chou)式(shi)兩種類型(xing)，它們都是(shi)由真(zhen)(zhen)空(kong)(kong)(kong)系(xi)統(tong)、抽(chou)充氣密封系(xi)統(tong)、熱壓封合系(xi)統(tong)、電器控制系(xi)統(tong)等組(zu)成。其(qi)中(zhong)內抽(chou)式(shi)包(bao)裝機是(shi)有真(zhen)(zhen)空(kong)(kong)(kong)室(shi)的，物(wu)品(pin)可以擺(bai)放在真(zhen)(zhen)空(kong)(kong)(kong)室(shi)里，合上(shang)真(zhen)(zhen)空(kong)(kong)(kong)機的真(zhen)(zhen)空(kong)(kong)(kong)室(shi)上(shang)蓋后，就形成密閉的空(kong)(kong)(kong)間(jian)，這樣就可以進行抽(chou)真(zhen)(zhen)空(kong)(kong)(kong)工(gong)作了，但是(shi)在工(gong)作過程中(zhong)，有時會出現真(zhen)(zhen)空(kong)(kong)(kong)蓋合不上(shang)的情況(kuang)
