真空包(bao)裝機廠的(de)真空(kong)包裝機增加充(chong)(chong)(chong)(chong)(chong)氣功能(neng)是(shi)(shi)有(you)兩種(zhong)(zhong)方式，一(yi)種(zhong)(zhong)是(shi)(shi)氣嘴(zui)直(zhi)接伸到產(chan)(chan)品(pin)袋子(zi)里(li)(li)面進行充(chong)(chong)(chong)(chong)(chong)氣的(de)，另一(yi)種(zhong)(zhong)是(shi)(shi)把要(yao)充(chong)(chong)(chong)(chong)(chong)的(de)氣體先充(chong)(chong)(chong)(chong)(chong)滿整個(ge)真空(kong)室，然后靠負(fu)壓差充(chong)(chong)(chong)(chong)(chong)滿袋子(zi)。那究竟采(cai)用(yong)哪種(zhong)(zhong)方式充(chong)(chong)(chong)(chong)(chong)氣好呢，這里(li)(li)主要(yao)看客(ke)戶(hu)的(de)產(chan)(chan)品(pin)性質，單純(chun)來說肯定(ding)(ding)是(shi)(shi)直(zhi)接沖(chong)到袋子(zi)里(li)(li)比較好，這樣置換的(de)又純(chun)還能(neng)省(sheng)不少氣源(yuan)，但是(shi)(shi)大家(jia)一(yi)定(ding)(ding)要(yao)考慮(lv)好自己產(chan)(chan)品(pin)性質。如果產(chan)(chan)品(pin)是(shi)(shi)顆粒(li)，我們可以(yi)采(cai)取(qu)起初一(yi)種(zhong)(zhong)方法(fa)直(zhi)接讓(rang)充(chong)(chong)(chong)(chong)(chong)氣嘴(zui)到袋子(zi)里(li)(li)進行充(chong)(chong)(chong)(chong)(chong)氣，但是(shi)(shi)如果你的(de)產(chan)(chan)品(pin)是(shi)(shi)粉末狀的(de)就不能(neng)用(yong)起初一(yi)種(zhong)(zhong)方法(fa)了(le)，需(xu)要(yao)第(di)二種(zhong)(zhong)在真空(kong)室充(chong)(chong)(chong)(chong)(chong)氣利用(yong)壓力差充(chong)(chong)(chong)(chong)(chong)滿袋子(zi)。可是(shi)(shi)客(ke)戶(hu)又要(yao)要(yao)求達到一(yi)定(ding)(ding)比例的(de)殘氧量，這就很(hen)矛盾了(le)。
