真空包裝機廠的真空(kong)包裝機(ji)增加充(chong)(chong)氣功能(neng)是(shi)(shi)有兩種(zhong)方(fang)(fang)式，一(yi)(yi)種(zhong)是(shi)(shi)氣嘴(zui)直(zhi)接伸到(dao)產(chan)品(pin)袋(dai)子(zi)里(li)面(mian)進行充(chong)(chong)氣的，另一(yi)(yi)種(zhong)是(shi)(shi)把要充(chong)(chong)的氣體先充(chong)(chong)滿(man)整個(ge)真空(kong)室，然后靠負壓差(cha)(cha)充(chong)(chong)滿(man)袋(dai)子(zi)。那究(jiu)竟采(cai)(cai)用(yong)(yong)哪(na)種(zhong)方(fang)(fang)式充(chong)(chong)氣好呢，這里(li)主要看客(ke)戶的產(chan)品(pin)性(xing)質，單純來說肯定是(shi)(shi)直(zhi)接沖到(dao)袋(dai)子(zi)里(li)比較好，這樣置換的又(you)純還(huan)能(neng)省不少(shao)氣源，但是(shi)(shi)大家一(yi)(yi)定要考慮好自己產(chan)品(pin)性(xing)質。如果產(chan)品(pin)是(shi)(shi)顆(ke)粒(li)，我(wo)們可以采(cai)(cai)取起初(chu)一(yi)(yi)種(zhong)方(fang)(fang)法直(zhi)接讓充(chong)(chong)氣嘴(zui)到(dao)袋(dai)子(zi)里(li)進行充(chong)(chong)氣，但是(shi)(shi)如果你的產(chan)品(pin)是(shi)(shi)粉(fen)末狀的就不能(neng)用(yong)(yong)起初(chu)一(yi)(yi)種(zhong)方(fang)(fang)法了，需要第(di)二種(zhong)在真空(kong)室充(chong)(chong)氣利(li)用(yong)(yong)壓力(li)差(cha)(cha)充(chong)(chong)滿(man)袋(dai)子(zi)。可是(shi)(shi)客(ke)戶又(you)要要求達到(dao)一(yi)(yi)定比例(li)的殘(can)氧量，這就很矛盾了。
