真(zhen)空包裝機廠的(de)(de)真(zhen)空(kong)包(bao)裝機增加充(chong)氣(qi)功能(neng)(neng)是(shi)(shi)有兩種(zhong)(zhong)方(fang)(fang)式，一種(zhong)(zhong)是(shi)(shi)氣(qi)嘴直(zhi)接伸到(dao)產(chan)(chan)品袋(dai)子(zi)(zi)(zi)里(li)(li)(li)面進(jin)行充(chong)氣(qi)的(de)(de)，另(ling)一種(zhong)(zhong)是(shi)(shi)把要(yao)充(chong)的(de)(de)氣(qi)體先充(chong)滿整個真(zhen)空(kong)室，然后靠負(fu)壓差充(chong)滿袋(dai)子(zi)(zi)(zi)。那究竟采(cai)用哪種(zhong)(zhong)方(fang)(fang)式充(chong)氣(qi)好呢(ni)，這里(li)(li)(li)主(zhu)要(yao)看客戶的(de)(de)產(chan)(chan)品性(xing)質，單純來說肯定(ding)是(shi)(shi)直(zhi)接沖到(dao)袋(dai)子(zi)(zi)(zi)里(li)(li)(li)比較好，這樣置換的(de)(de)又純還能(neng)(neng)省(sheng)不少氣(qi)源，但是(shi)(shi)大家一定(ding)要(yao)考(kao)慮好自己產(chan)(chan)品性(xing)質。如(ru)果產(chan)(chan)品是(shi)(shi)顆粒，我們可以(yi)采(cai)取起初一種(zhong)(zhong)方(fang)(fang)法直(zhi)接讓充(chong)氣(qi)嘴到(dao)袋(dai)子(zi)(zi)(zi)里(li)(li)(li)進(jin)行充(chong)氣(qi)，但是(shi)(shi)如(ru)果你的(de)(de)產(chan)(chan)品是(shi)(shi)粉末狀的(de)(de)就不能(neng)(neng)用起初一種(zhong)(zhong)方(fang)(fang)法了，需要(yao)第二種(zhong)(zhong)在真(zhen)空(kong)室充(chong)氣(qi)利用壓力差充(chong)滿袋(dai)子(zi)(zi)(zi)。可是(shi)(shi)客戶又要(yao)要(yao)求達到(dao)一定(ding)比例的(de)(de)殘氧量，這就很矛盾了。
