真空包裝(zhuang)機廠(chang)的(de)真(zhen)空包裝機增(zeng)加充(chong)(chong)氣(qi)功能(neng)是有(you)兩種(zhong)(zhong)方式(shi)，一(yi)種(zhong)(zhong)是氣(qi)嘴直(zhi)(zhi)接伸到產(chan)品袋(dai)子(zi)里面進行充(chong)(chong)氣(qi)的(de)，另一(yi)種(zhong)(zhong)是把要(yao)(yao)充(chong)(chong)的(de)氣(qi)體先充(chong)(chong)滿整(zheng)個真(zhen)空室(shi)，然后靠負壓(ya)(ya)差(cha)充(chong)(chong)滿袋(dai)子(zi)。那(nei)究竟采(cai)(cai)用(yong)哪種(zhong)(zhong)方式(shi)充(chong)(chong)氣(qi)好呢，這里主要(yao)(yao)看客戶的(de)產(chan)品性質，單(dan)純(chun)來(lai)說(shuo)肯定(ding)是直(zhi)(zhi)接沖到袋(dai)子(zi)里比較好，這樣置(zhi)換的(de)又(you)(you)純(chun)還能(neng)省不(bu)少氣(qi)源，但是大(da)家一(yi)定(ding)要(yao)(yao)考慮好自己產(chan)品性質。如(ru)(ru)果(guo)產(chan)品是顆(ke)粒(li)，我們可以采(cai)(cai)取起初一(yi)種(zhong)(zhong)方法(fa)直(zhi)(zhi)接讓充(chong)(chong)氣(qi)嘴到袋(dai)子(zi)里進行充(chong)(chong)氣(qi)，但是如(ru)(ru)果(guo)你的(de)產(chan)品是粉末狀(zhuang)的(de)就不(bu)能(neng)用(yong)起初一(yi)種(zhong)(zhong)方法(fa)了，需要(yao)(yao)第二(er)種(zhong)(zhong)在真(zhen)空室(shi)充(chong)(chong)氣(qi)利用(yong)壓(ya)(ya)力(li)差(cha)充(chong)(chong)滿袋(dai)子(zi)。可是客戶又(you)(you)要(yao)(yao)要(yao)(yao)求達到一(yi)定(ding)比例(li)的(de)殘氧量，這就很矛盾了。
