真空包裝機廠的(de)(de)真(zhen)空包裝機增加充(chong)(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)有兩種(zhong)(zhong)方式，一(yi)(yi)種(zhong)(zhong)是(shi)氣(qi)(qi)嘴直(zhi)(zhi)接伸到(dao)產品袋(dai)子(zi)里(li)面進行充(chong)(chong)(chong)(chong)氣(qi)(qi)的(de)(de)，另一(yi)(yi)種(zhong)(zhong)是(shi)把(ba)要(yao)充(chong)(chong)(chong)(chong)的(de)(de)氣(qi)(qi)體先充(chong)(chong)(chong)(chong)滿整個真(zhen)空室(shi)(shi)，然后靠(kao)負壓差充(chong)(chong)(chong)(chong)滿袋(dai)子(zi)。那究(jiu)竟采用哪(na)種(zhong)(zhong)方式充(chong)(chong)(chong)(chong)氣(qi)(qi)好(hao)呢，這(zhe)里(li)主(zhu)要(yao)看客(ke)(ke)戶的(de)(de)產品性(xing)質，單(dan)純來說(shuo)肯定(ding)是(shi)直(zhi)(zhi)接沖到(dao)袋(dai)子(zi)里(li)比較好(hao)，這(zhe)樣置換的(de)(de)又(you)純還能(neng)省不少(shao)氣(qi)(qi)源，但(dan)是(shi)大家一(yi)(yi)定(ding)要(yao)考慮好(hao)自己產品性(xing)質。如(ru)果(guo)產品是(shi)顆粒，我們可(ke)以(yi)采取起初一(yi)(yi)種(zhong)(zhong)方法直(zhi)(zhi)接讓(rang)充(chong)(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋(dai)子(zi)里(li)進行充(chong)(chong)(chong)(chong)氣(qi)(qi)，但(dan)是(shi)如(ru)果(guo)你的(de)(de)產品是(shi)粉末狀的(de)(de)就(jiu)不能(neng)用起初一(yi)(yi)種(zhong)(zhong)方法了，需要(yao)第二種(zhong)(zhong)在真(zhen)空室(shi)(shi)充(chong)(chong)(chong)(chong)氣(qi)(qi)利用壓力差充(chong)(chong)(chong)(chong)滿袋(dai)子(zi)。可(ke)是(shi)客(ke)(ke)戶又(you)要(yao)要(yao)求達(da)到(dao)一(yi)(yi)定(ding)比例的(de)(de)殘氧量，這(zhe)就(jiu)很矛(mao)盾了。
