真空包裝(zhuang)機廠(chang)的真空(kong)(kong)包(bao)裝(zhuang)機(ji)增(zeng)加充(chong)(chong)(chong)(chong)(chong)氣功能是(shi)(shi)有(you)兩(liang)種(zhong)方式，一(yi)(yi)種(zhong)是(shi)(shi)氣嘴直(zhi)接伸(shen)到產(chan)(chan)品(pin)(pin)(pin)袋(dai)子(zi)里(li)面進行充(chong)(chong)(chong)(chong)(chong)氣的，另一(yi)(yi)種(zhong)是(shi)(shi)把要充(chong)(chong)(chong)(chong)(chong)的氣體先充(chong)(chong)(chong)(chong)(chong)滿整個真空(kong)(kong)室，然后靠負壓差充(chong)(chong)(chong)(chong)(chong)滿袋(dai)子(zi)。那究竟采用(yong)哪種(zhong)方式充(chong)(chong)(chong)(chong)(chong)氣好呢(ni)，這(zhe)里(li)主(zhu)要看客(ke)戶的產(chan)(chan)品(pin)(pin)(pin)性(xing)質，單純(chun)來說肯定(ding)是(shi)(shi)直(zhi)接沖到袋(dai)子(zi)里(li)比較(jiao)好，這(zhe)樣置換(huan)的又純(chun)還能省不少氣源，但(dan)(dan)是(shi)(shi)大家一(yi)(yi)定(ding)要考慮好自己產(chan)(chan)品(pin)(pin)(pin)性(xing)質。如果產(chan)(chan)品(pin)(pin)(pin)是(shi)(shi)顆粒，我(wo)們(men)可以采取起初(chu)一(yi)(yi)種(zhong)方法(fa)直(zhi)接讓充(chong)(chong)(chong)(chong)(chong)氣嘴到袋(dai)子(zi)里(li)進行充(chong)(chong)(chong)(chong)(chong)氣，但(dan)(dan)是(shi)(shi)如果你的產(chan)(chan)品(pin)(pin)(pin)是(shi)(shi)粉末(mo)狀的就不能用(yong)起初(chu)一(yi)(yi)種(zhong)方法(fa)了，需要第二種(zhong)在真空(kong)(kong)室充(chong)(chong)(chong)(chong)(chong)氣利用(yong)壓力(li)差充(chong)(chong)(chong)(chong)(chong)滿袋(dai)子(zi)。可是(shi)(shi)客(ke)戶又要要求達到一(yi)(yi)定(ding)比例的殘(can)氧量，這(zhe)就很矛(mao)盾了。
