真空包裝機廠的(de)(de)真(zhen)空包裝機增加充(chong)(chong)(chong)(chong)(chong)氣(qi)功能(neng)是(shi)(shi)有(you)兩種(zhong)(zhong)(zhong)(zhong)方式(shi)，一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)嘴直接(jie)伸到(dao)(dao)產品(pin)(pin)袋(dai)子里(li)面進行(xing)充(chong)(chong)(chong)(chong)(chong)氣(qi)的(de)(de)，另一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)把要(yao)充(chong)(chong)(chong)(chong)(chong)的(de)(de)氣(qi)體先(xian)充(chong)(chong)(chong)(chong)(chong)滿整個(ge)真(zhen)空室，然后靠(kao)負壓差(cha)充(chong)(chong)(chong)(chong)(chong)滿袋(dai)子。那(nei)究(jiu)竟采(cai)用哪(na)種(zhong)(zhong)(zhong)(zhong)方式(shi)充(chong)(chong)(chong)(chong)(chong)氣(qi)好(hao)呢，這(zhe)里(li)主(zhu)要(yao)看客戶的(de)(de)產品(pin)(pin)性質，單(dan)純(chun)來(lai)說肯定(ding)是(shi)(shi)直接(jie)沖到(dao)(dao)袋(dai)子里(li)比(bi)較好(hao)，這(zhe)樣(yang)置換的(de)(de)又(you)純(chun)還能(neng)省(sheng)不少氣(qi)源，但是(shi)(shi)大家一(yi)定(ding)要(yao)考慮好(hao)自己產品(pin)(pin)性質。如果產品(pin)(pin)是(shi)(shi)顆粒，我們(men)可以采(cai)取起初一(yi)種(zhong)(zhong)(zhong)(zhong)方法直接(jie)讓充(chong)(chong)(chong)(chong)(chong)氣(qi)嘴到(dao)(dao)袋(dai)子里(li)進行(xing)充(chong)(chong)(chong)(chong)(chong)氣(qi)，但是(shi)(shi)如果你的(de)(de)產品(pin)(pin)是(shi)(shi)粉末(mo)狀的(de)(de)就不能(neng)用起初一(yi)種(zhong)(zhong)(zhong)(zhong)方法了，需要(yao)第(di)二種(zhong)(zhong)(zhong)(zhong)在(zai)真(zhen)空室充(chong)(chong)(chong)(chong)(chong)氣(qi)利(li)用壓力差(cha)充(chong)(chong)(chong)(chong)(chong)滿袋(dai)子。可是(shi)(shi)客戶又(you)要(yao)要(yao)求(qiu)達到(dao)(dao)一(yi)定(ding)比(bi)例的(de)(de)殘(can)氧量，這(zhe)就很矛盾了。
