真(zhen)空包(bao)裝機廠的(de)真空(kong)包(bao)裝機增加充氣(qi)(qi)功能是(shi)(shi)(shi)(shi)有兩種(zhong)(zhong)(zhong)方式，一種(zhong)(zhong)(zhong)是(shi)(shi)(shi)(shi)氣(qi)(qi)嘴直接(jie)(jie)伸到(dao)(dao)產品袋(dai)子(zi)(zi)里面進行充氣(qi)(qi)的(de)，另一種(zhong)(zhong)(zhong)是(shi)(shi)(shi)(shi)把要(yao)充的(de)氣(qi)(qi)體先(xian)充滿(man)整個真空(kong)室，然后靠負(fu)壓差充滿(man)袋(dai)子(zi)(zi)。那究(jiu)竟采(cai)用哪種(zhong)(zhong)(zhong)方式充氣(qi)(qi)好(hao)呢，這(zhe)(zhe)里主(zhu)要(yao)看客戶(hu)的(de)產品性質(zhi)，單純來說肯定是(shi)(shi)(shi)(shi)直接(jie)(jie)沖到(dao)(dao)袋(dai)子(zi)(zi)里比較(jiao)好(hao)，這(zhe)(zhe)樣置換的(de)又純還(huan)能省不少氣(qi)(qi)源，但(dan)是(shi)(shi)(shi)(shi)大(da)家一定要(yao)考慮好(hao)自己產品性質(zhi)。如(ru)果產品是(shi)(shi)(shi)(shi)顆粒，我們(men)可(ke)以(yi)采(cai)取起初一種(zhong)(zhong)(zhong)方法直接(jie)(jie)讓充氣(qi)(qi)嘴到(dao)(dao)袋(dai)子(zi)(zi)里進行充氣(qi)(qi)，但(dan)是(shi)(shi)(shi)(shi)如(ru)果你的(de)產品是(shi)(shi)(shi)(shi)粉末狀的(de)就不能用起初一種(zhong)(zhong)(zhong)方法了，需要(yao)第二種(zhong)(zhong)(zhong)在真空(kong)室充氣(qi)(qi)利用壓力差充滿(man)袋(dai)子(zi)(zi)。可(ke)是(shi)(shi)(shi)(shi)客戶(hu)又要(yao)要(yao)求達(da)到(dao)(dao)一定比例的(de)殘(can)氧量，這(zhe)(zhe)就很矛盾了。
