真空包(bao)裝機廠的(de)(de)真(zhen)空包裝(zhuang)機增加(jia)充(chong)(chong)氣(qi)功能(neng)是(shi)(shi)(shi)(shi)有兩(liang)種(zhong)方(fang)式(shi)，一(yi)種(zhong)是(shi)(shi)(shi)(shi)氣(qi)嘴直接(jie)伸(shen)到產品袋(dai)子(zi)里(li)面進(jin)行充(chong)(chong)氣(qi)的(de)(de)，另(ling)一(yi)種(zhong)是(shi)(shi)(shi)(shi)把要(yao)充(chong)(chong)的(de)(de)氣(qi)體先(xian)充(chong)(chong)滿(man)(man)整個真(zhen)空室(shi)，然后靠負壓(ya)差(cha)充(chong)(chong)滿(man)(man)袋(dai)子(zi)。那究竟采(cai)用(yong)哪種(zhong)方(fang)式(shi)充(chong)(chong)氣(qi)好呢(ni)，這里(li)主要(yao)看客(ke)戶的(de)(de)產品性質，單純來(lai)說肯定(ding)是(shi)(shi)(shi)(shi)直接(jie)沖到袋(dai)子(zi)里(li)比(bi)較好，這樣置換的(de)(de)又純還能(neng)省不少氣(qi)源，但(dan)是(shi)(shi)(shi)(shi)大家一(yi)定(ding)要(yao)考(kao)慮(lv)好自己(ji)產品性質。如果產品是(shi)(shi)(shi)(shi)顆(ke)粒，我們(men)可(ke)以采(cai)取起(qi)初一(yi)種(zhong)方(fang)法直接(jie)讓充(chong)(chong)氣(qi)嘴到袋(dai)子(zi)里(li)進(jin)行充(chong)(chong)氣(qi)，但(dan)是(shi)(shi)(shi)(shi)如果你(ni)的(de)(de)產品是(shi)(shi)(shi)(shi)粉末(mo)狀的(de)(de)就不能(neng)用(yong)起(qi)初一(yi)種(zhong)方(fang)法了，需要(yao)第(di)二種(zhong)在真(zhen)空室(shi)充(chong)(chong)氣(qi)利用(yong)壓(ya)力差(cha)充(chong)(chong)滿(man)(man)袋(dai)子(zi)。可(ke)是(shi)(shi)(shi)(shi)客(ke)戶又要(yao)要(yao)求(qiu)達到一(yi)定(ding)比(bi)例的(de)(de)殘氧量，這就很(hen)矛盾了。
