真空包裝機廠的(de)(de)真(zhen)空包裝機增加充(chong)(chong)氣(qi)(qi)功能是(shi)(shi)(shi)有兩(liang)種(zhong)方(fang)式，一(yi)(yi)種(zhong)是(shi)(shi)(shi)氣(qi)(qi)嘴(zui)直接伸到產(chan)(chan)品(pin)袋子(zi)里面(mian)進行(xing)充(chong)(chong)氣(qi)(qi)的(de)(de)，另一(yi)(yi)種(zhong)是(shi)(shi)(shi)把要(yao)(yao)充(chong)(chong)的(de)(de)氣(qi)(qi)體先充(chong)(chong)滿整個真(zhen)空室，然(ran)后靠負壓(ya)差(cha)充(chong)(chong)滿袋子(zi)。那究竟采(cai)用哪種(zhong)方(fang)式充(chong)(chong)氣(qi)(qi)好呢(ni)，這(zhe)里主要(yao)(yao)看客(ke)戶的(de)(de)產(chan)(chan)品(pin)性(xing)質，單純(chun)來說肯定是(shi)(shi)(shi)直接沖到袋子(zi)里比較好，這(zhe)樣置換的(de)(de)又純(chun)還能省(sheng)不少氣(qi)(qi)源(yuan)，但是(shi)(shi)(shi)大家一(yi)(yi)定要(yao)(yao)考(kao)慮好自己(ji)產(chan)(chan)品(pin)性(xing)質。如果產(chan)(chan)品(pin)是(shi)(shi)(shi)顆(ke)粒，我們(men)可(ke)以(yi)采(cai)取起初一(yi)(yi)種(zhong)方(fang)法(fa)直接讓充(chong)(chong)氣(qi)(qi)嘴(zui)到袋子(zi)里進行(xing)充(chong)(chong)氣(qi)(qi)，但是(shi)(shi)(shi)如果你的(de)(de)產(chan)(chan)品(pin)是(shi)(shi)(shi)粉末狀的(de)(de)就不能用起初一(yi)(yi)種(zhong)方(fang)法(fa)了，需要(yao)(yao)第二(er)種(zhong)在真(zhen)空室充(chong)(chong)氣(qi)(qi)利(li)用壓(ya)力(li)差(cha)充(chong)(chong)滿袋子(zi)。可(ke)是(shi)(shi)(shi)客(ke)戶又要(yao)(yao)要(yao)(yao)求(qiu)達到一(yi)(yi)定比例的(de)(de)殘氧量，這(zhe)就很矛(mao)盾了。
