真空包裝(zhuang)機廠(chang)的(de)(de)真(zhen)空包裝機(ji)增加充(chong)(chong)(chong)氣(qi)(qi)功能是(shi)有兩種(zhong)(zhong)方式，一(yi)種(zhong)(zhong)是(shi)氣(qi)(qi)嘴直(zhi)接伸到(dao)產品(pin)袋(dai)(dai)子(zi)里(li)面進(jin)行充(chong)(chong)(chong)氣(qi)(qi)的(de)(de)，另一(yi)種(zhong)(zhong)是(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)(qi)體先充(chong)(chong)(chong)滿整個真(zhen)空室，然后靠負壓(ya)差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)。那究竟(jing)采(cai)用哪種(zhong)(zhong)方式充(chong)(chong)(chong)氣(qi)(qi)好(hao)呢，這(zhe)里(li)主要(yao)看客戶(hu)的(de)(de)產品(pin)性質(zhi)，單純來說肯定(ding)是(shi)直(zhi)接沖到(dao)袋(dai)(dai)子(zi)里(li)比較(jiao)好(hao)，這(zhe)樣置換的(de)(de)又純還能省不(bu)(bu)少氣(qi)(qi)源，但是(shi)大家一(yi)定(ding)要(yao)考(kao)慮(lv)好(hao)自己產品(pin)性質(zhi)。如(ru)果產品(pin)是(shi)顆粒(li)，我(wo)們(men)可(ke)以采(cai)取起(qi)初(chu)一(yi)種(zhong)(zhong)方法(fa)直(zhi)接讓(rang)充(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋(dai)(dai)子(zi)里(li)進(jin)行充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)如(ru)果你的(de)(de)產品(pin)是(shi)粉末狀的(de)(de)就不(bu)(bu)能用起(qi)初(chu)一(yi)種(zhong)(zhong)方法(fa)了，需要(yao)第二種(zhong)(zhong)在真(zhen)空室充(chong)(chong)(chong)氣(qi)(qi)利用壓(ya)力差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)。可(ke)是(shi)客戶(hu)又要(yao)要(yao)求達到(dao)一(yi)定(ding)比例的(de)(de)殘氧量，這(zhe)就很矛(mao)盾了。
