真空(kong)包裝機廠的真(zhen)空包裝機增加充(chong)(chong)(chong)(chong)氣功(gong)能(neng)(neng)是(shi)有(you)兩種(zhong)方(fang)式(shi)，一(yi)(yi)種(zhong)是(shi)氣嘴直接伸到(dao)產(chan)(chan)品袋(dai)(dai)子(zi)里面(mian)進(jin)行充(chong)(chong)(chong)(chong)氣的，另一(yi)(yi)種(zhong)是(shi)把要(yao)充(chong)(chong)(chong)(chong)的氣體先充(chong)(chong)(chong)(chong)滿整個真(zhen)空室，然(ran)后靠負壓差充(chong)(chong)(chong)(chong)滿袋(dai)(dai)子(zi)。那究竟采用(yong)哪種(zhong)方(fang)式(shi)充(chong)(chong)(chong)(chong)氣好(hao)呢，這(zhe)里主要(yao)看客(ke)戶的產(chan)(chan)品性質，單純來說肯定是(shi)直接沖到(dao)袋(dai)(dai)子(zi)里比較好(hao)，這(zhe)樣置(zhi)換的又(you)純還能(neng)(neng)省不(bu)少(shao)氣源，但是(shi)大家一(yi)(yi)定要(yao)考慮(lv)好(hao)自己產(chan)(chan)品性質。如(ru)果產(chan)(chan)品是(shi)顆粒，我們可以采取(qu)起(qi)初(chu)一(yi)(yi)種(zhong)方(fang)法直接讓充(chong)(chong)(chong)(chong)氣嘴到(dao)袋(dai)(dai)子(zi)里進(jin)行充(chong)(chong)(chong)(chong)氣，但是(shi)如(ru)果你的產(chan)(chan)品是(shi)粉(fen)末狀的就不(bu)能(neng)(neng)用(yong)起(qi)初(chu)一(yi)(yi)種(zhong)方(fang)法了，需(xu)要(yao)第二種(zhong)在真(zhen)空室充(chong)(chong)(chong)(chong)氣利用(yong)壓力差充(chong)(chong)(chong)(chong)滿袋(dai)(dai)子(zi)。可是(shi)客(ke)戶又(you)要(yao)要(yao)求達(da)到(dao)一(yi)(yi)定比例的殘(can)氧量，這(zhe)就很矛盾了。
