真空包裝(zhuang)機廠的(de)真空(kong)包裝機(ji)增加充氣(qi)(qi)功能(neng)是(shi)有兩種(zhong)(zhong)(zhong)(zhong)方(fang)式(shi)，一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)嘴直接伸(shen)到(dao)產品袋子(zi)(zi)(zi)里(li)面進行充氣(qi)(qi)的(de)，另一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)把要(yao)充的(de)氣(qi)(qi)體先充滿(man)整個真空(kong)室，然后靠負壓差充滿(man)袋子(zi)(zi)(zi)。那究竟(jing)采(cai)用(yong)哪種(zhong)(zhong)(zhong)(zhong)方(fang)式(shi)充氣(qi)(qi)好呢，這里(li)主要(yao)看客(ke)(ke)戶的(de)產品性質(zhi)，單純來說肯定(ding)是(shi)直接沖(chong)到(dao)袋子(zi)(zi)(zi)里(li)比較(jiao)好，這樣置(zhi)換的(de)又(you)純還能(neng)省不少氣(qi)(qi)源，但是(shi)大家(jia)一(yi)定(ding)要(yao)考慮好自己產品性質(zhi)。如果(guo)產品是(shi)顆粒，我們(men)可以采(cai)取起(qi)初(chu)一(yi)種(zhong)(zhong)(zhong)(zhong)方(fang)法(fa)直接讓充氣(qi)(qi)嘴到(dao)袋子(zi)(zi)(zi)里(li)進行充氣(qi)(qi)，但是(shi)如果(guo)你的(de)產品是(shi)粉(fen)末狀的(de)就(jiu)不能(neng)用(yong)起(qi)初(chu)一(yi)種(zhong)(zhong)(zhong)(zhong)方(fang)法(fa)了，需要(yao)第二(er)種(zhong)(zhong)(zhong)(zhong)在真空(kong)室充氣(qi)(qi)利用(yong)壓力差充滿(man)袋子(zi)(zi)(zi)。可是(shi)客(ke)(ke)戶又(you)要(yao)要(yao)求達到(dao)一(yi)定(ding)比例的(de)殘氧(yang)量，這就(jiu)很(hen)矛盾(dun)了。
