真空包裝機廠的(de)(de)(de)真(zhen)空包裝機增加(jia)充(chong)(chong)氣(qi)(qi)功能(neng)是(shi)(shi)有兩(liang)種(zhong)(zhong)方式(shi)，一(yi)(yi)(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)(qi)嘴(zui)直接伸到(dao)產(chan)品(pin)(pin)袋子(zi)里面進(jin)行充(chong)(chong)氣(qi)(qi)的(de)(de)(de)，另一(yi)(yi)(yi)種(zhong)(zhong)是(shi)(shi)把要(yao)(yao)(yao)充(chong)(chong)的(de)(de)(de)氣(qi)(qi)體先充(chong)(chong)滿整個真(zhen)空室(shi)，然后靠(kao)負壓差(cha)充(chong)(chong)滿袋子(zi)。那究竟采(cai)用(yong)哪種(zhong)(zhong)方式(shi)充(chong)(chong)氣(qi)(qi)好呢(ni)，這里主要(yao)(yao)(yao)看客戶的(de)(de)(de)產(chan)品(pin)(pin)性(xing)質，單純來說肯定是(shi)(shi)直接沖到(dao)袋子(zi)里比較好，這樣(yang)置換(huan)的(de)(de)(de)又(you)純還能(neng)省(sheng)不少氣(qi)(qi)源，但是(shi)(shi)大家一(yi)(yi)(yi)定要(yao)(yao)(yao)考(kao)慮好自己(ji)產(chan)品(pin)(pin)性(xing)質。如果(guo)(guo)產(chan)品(pin)(pin)是(shi)(shi)顆粒，我們可以采(cai)取(qu)起(qi)初(chu)一(yi)(yi)(yi)種(zhong)(zhong)方法(fa)(fa)直接讓充(chong)(chong)氣(qi)(qi)嘴(zui)到(dao)袋子(zi)里進(jin)行充(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如果(guo)(guo)你的(de)(de)(de)產(chan)品(pin)(pin)是(shi)(shi)粉末狀的(de)(de)(de)就不能(neng)用(yong)起(qi)初(chu)一(yi)(yi)(yi)種(zhong)(zhong)方法(fa)(fa)了(le)，需要(yao)(yao)(yao)第二種(zhong)(zhong)在真(zhen)空室(shi)充(chong)(chong)氣(qi)(qi)利用(yong)壓力(li)差(cha)充(chong)(chong)滿袋子(zi)。可是(shi)(shi)客戶又(you)要(yao)(yao)(yao)要(yao)(yao)(yao)求達(da)到(dao)一(yi)(yi)(yi)定比例(li)的(de)(de)(de)殘氧量，這就很矛盾(dun)了(le)。
