真空包(bao)裝機(ji)廠(chang)的(de)(de)(de)真(zhen)空包裝機增加充氣(qi)(qi)功能(neng)是(shi)有兩種(zhong)(zhong)(zhong)(zhong)方式(shi)，一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)嘴(zui)(zui)直(zhi)接伸到產(chan)(chan)(chan)品(pin)(pin)袋(dai)子里(li)(li)面進行(xing)充氣(qi)(qi)的(de)(de)(de)，另一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)把要(yao)(yao)充的(de)(de)(de)氣(qi)(qi)體先充滿整個真(zhen)空室，然后靠負壓差充滿袋(dai)子。那究竟采用(yong)哪種(zhong)(zhong)(zhong)(zhong)方式(shi)充氣(qi)(qi)好(hao)呢(ni)，這里(li)(li)主(zhu)要(yao)(yao)看(kan)客戶(hu)(hu)的(de)(de)(de)產(chan)(chan)(chan)品(pin)(pin)性質(zhi)，單純(chun)來說肯定是(shi)直(zhi)接沖(chong)到袋(dai)子里(li)(li)比(bi)較(jiao)好(hao)，這樣(yang)置換的(de)(de)(de)又(you)純(chun)還能(neng)省不少氣(qi)(qi)源，但(dan)是(shi)大家一(yi)定要(yao)(yao)考慮好(hao)自(zi)己產(chan)(chan)(chan)品(pin)(pin)性質(zhi)。如(ru)果產(chan)(chan)(chan)品(pin)(pin)是(shi)顆(ke)粒(li)，我們(men)可以采取(qu)起(qi)初(chu)一(yi)種(zhong)(zhong)(zhong)(zhong)方法(fa)直(zhi)接讓充氣(qi)(qi)嘴(zui)(zui)到袋(dai)子里(li)(li)進行(xing)充氣(qi)(qi)，但(dan)是(shi)如(ru)果你的(de)(de)(de)產(chan)(chan)(chan)品(pin)(pin)是(shi)粉末狀的(de)(de)(de)就不能(neng)用(yong)起(qi)初(chu)一(yi)種(zhong)(zhong)(zhong)(zhong)方法(fa)了(le)，需要(yao)(yao)第二(er)種(zhong)(zhong)(zhong)(zhong)在(zai)真(zhen)空室充氣(qi)(qi)利(li)用(yong)壓力差充滿袋(dai)子。可是(shi)客戶(hu)(hu)又(you)要(yao)(yao)要(yao)(yao)求(qiu)達(da)到一(yi)定比(bi)例的(de)(de)(de)殘氧量(liang)，這就很(hen)矛盾了(le)。
