真空包裝機廠的(de)(de)(de)真(zhen)(zhen)空包(bao)裝機(ji)增加充(chong)(chong)(chong)氣(qi)(qi)(qi)功能(neng)是(shi)(shi)(shi)(shi)(shi)有兩種(zhong)方(fang)(fang)式，一(yi)種(zhong)是(shi)(shi)(shi)(shi)(shi)氣(qi)(qi)(qi)嘴(zui)(zui)直(zhi)接伸到產(chan)(chan)品袋子(zi)里面進行(xing)充(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)(de)(de)，另(ling)一(yi)種(zhong)是(shi)(shi)(shi)(shi)(shi)把要充(chong)(chong)(chong)的(de)(de)(de)氣(qi)(qi)(qi)體先充(chong)(chong)(chong)滿(man)整個真(zhen)(zhen)空室(shi)，然后(hou)靠負壓差充(chong)(chong)(chong)滿(man)袋子(zi)。那究竟采用哪種(zhong)方(fang)(fang)式充(chong)(chong)(chong)氣(qi)(qi)(qi)好呢，這里主要看(kan)客(ke)戶的(de)(de)(de)產(chan)(chan)品性(xing)質(zhi)，單純(chun)來說(shuo)肯定是(shi)(shi)(shi)(shi)(shi)直(zhi)接沖到袋子(zi)里比(bi)較好，這樣(yang)置換的(de)(de)(de)又純(chun)還能(neng)省不(bu)少氣(qi)(qi)(qi)源(yuan)，但是(shi)(shi)(shi)(shi)(shi)大家(jia)一(yi)定要考慮好自己產(chan)(chan)品性(xing)質(zhi)。如果產(chan)(chan)品是(shi)(shi)(shi)(shi)(shi)顆粒，我們可以(yi)采取起初(chu)一(yi)種(zhong)方(fang)(fang)法直(zhi)接讓充(chong)(chong)(chong)氣(qi)(qi)(qi)嘴(zui)(zui)到袋子(zi)里進行(xing)充(chong)(chong)(chong)氣(qi)(qi)(qi)，但是(shi)(shi)(shi)(shi)(shi)如果你的(de)(de)(de)產(chan)(chan)品是(shi)(shi)(shi)(shi)(shi)粉末狀的(de)(de)(de)就不(bu)能(neng)用起初(chu)一(yi)種(zhong)方(fang)(fang)法了(le)，需要第二種(zhong)在真(zhen)(zhen)空室(shi)充(chong)(chong)(chong)氣(qi)(qi)(qi)利用壓力差充(chong)(chong)(chong)滿(man)袋子(zi)。可是(shi)(shi)(shi)(shi)(shi)客(ke)戶又要要求達到一(yi)定比(bi)例的(de)(de)(de)殘氧(yang)量(liang)，這就很(hen)矛盾了(le)。
