真(zhen)空包(bao)裝機廠的(de)真(zhen)空(kong)包裝機增加充(chong)(chong)(chong)(chong)氣(qi)功能(neng)是有兩種(zhong)(zhong)方式，一(yi)種(zhong)(zhong)是氣(qi)嘴直接伸到產(chan)品(pin)袋(dai)(dai)子(zi)(zi)里(li)(li)面進行(xing)充(chong)(chong)(chong)(chong)氣(qi)的(de)，另一(yi)種(zhong)(zhong)是把要(yao)充(chong)(chong)(chong)(chong)的(de)氣(qi)體先充(chong)(chong)(chong)(chong)滿整個真(zhen)空(kong)室，然后靠負壓差(cha)充(chong)(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。那(nei)究竟采用哪種(zhong)(zhong)方式充(chong)(chong)(chong)(chong)氣(qi)好呢(ni)，這(zhe)(zhe)里(li)(li)主要(yao)看客(ke)(ke)戶的(de)產(chan)品(pin)性質，單純來說肯(ken)定(ding)是直接沖到袋(dai)(dai)子(zi)(zi)里(li)(li)比(bi)較好，這(zhe)(zhe)樣(yang)置換的(de)又(you)純還能(neng)省不少氣(qi)源，但是大(da)家(jia)一(yi)定(ding)要(yao)考慮好自己產(chan)品(pin)性質。如(ru)果產(chan)品(pin)是顆(ke)粒，我們可以采取起初(chu)一(yi)種(zhong)(zhong)方法(fa)直接讓充(chong)(chong)(chong)(chong)氣(qi)嘴到袋(dai)(dai)子(zi)(zi)里(li)(li)進行(xing)充(chong)(chong)(chong)(chong)氣(qi)，但是如(ru)果你(ni)的(de)產(chan)品(pin)是粉(fen)末狀的(de)就不能(neng)用起初(chu)一(yi)種(zhong)(zhong)方法(fa)了，需要(yao)第二種(zhong)(zhong)在真(zhen)空(kong)室充(chong)(chong)(chong)(chong)氣(qi)利用壓力差(cha)充(chong)(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。可是客(ke)(ke)戶又(you)要(yao)要(yao)求達到一(yi)定(ding)比(bi)例的(de)殘氧量，這(zhe)(zhe)就很矛盾(dun)了。
