真空包裝機廠的(de)(de)真(zhen)空(kong)(kong)包裝機(ji)增加充(chong)(chong)氣功能(neng)是(shi)(shi)(shi)有兩種方式(shi)，一(yi)(yi)種是(shi)(shi)(shi)氣嘴(zui)直接(jie)伸到(dao)(dao)產(chan)(chan)品袋(dai)(dai)子(zi)里面進行充(chong)(chong)氣的(de)(de)，另一(yi)(yi)種是(shi)(shi)(shi)把要充(chong)(chong)的(de)(de)氣體先充(chong)(chong)滿(man)(man)整個真(zhen)空(kong)(kong)室(shi)，然后靠負壓差充(chong)(chong)滿(man)(man)袋(dai)(dai)子(zi)。那究竟采(cai)用(yong)(yong)哪種方式(shi)充(chong)(chong)氣好呢，這(zhe)里主要看客(ke)戶的(de)(de)產(chan)(chan)品性質，單純來說肯定(ding)是(shi)(shi)(shi)直接(jie)沖(chong)到(dao)(dao)袋(dai)(dai)子(zi)里比(bi)較好，這(zhe)樣(yang)置換(huan)的(de)(de)又(you)純還能(neng)省不少氣源，但(dan)(dan)是(shi)(shi)(shi)大家一(yi)(yi)定(ding)要考慮好自己產(chan)(chan)品性質。如果產(chan)(chan)品是(shi)(shi)(shi)顆(ke)粒，我們可以采(cai)取起初一(yi)(yi)種方法直接(jie)讓充(chong)(chong)氣嘴(zui)到(dao)(dao)袋(dai)(dai)子(zi)里進行充(chong)(chong)氣，但(dan)(dan)是(shi)(shi)(shi)如果你的(de)(de)產(chan)(chan)品是(shi)(shi)(shi)粉末狀的(de)(de)就不能(neng)用(yong)(yong)起初一(yi)(yi)種方法了，需要第二種在(zai)真(zhen)空(kong)(kong)室(shi)充(chong)(chong)氣利用(yong)(yong)壓力差充(chong)(chong)滿(man)(man)袋(dai)(dai)子(zi)。可是(shi)(shi)(shi)客(ke)戶又(you)要要求達(da)到(dao)(dao)一(yi)(yi)定(ding)比(bi)例的(de)(de)殘氧量，這(zhe)就很矛(mao)盾了。
