真空包裝機(ji)廠(chang)的(de)(de)真空包(bao)裝機增(zeng)加充(chong)(chong)氣功(gong)能是(shi)有(you)兩種(zhong)方式(shi)，一(yi)種(zhong)是(shi)氣嘴直接伸到產(chan)品(pin)袋子(zi)里(li)面(mian)進(jin)行(xing)(xing)充(chong)(chong)氣的(de)(de)，另一(yi)種(zhong)是(shi)把(ba)要(yao)(yao)充(chong)(chong)的(de)(de)氣體先(xian)充(chong)(chong)滿(man)(man)整個真空室(shi)，然(ran)后靠負壓(ya)差(cha)充(chong)(chong)滿(man)(man)袋子(zi)。那究竟采用(yong)哪種(zhong)方式(shi)充(chong)(chong)氣好(hao)呢，這里(li)主(zhu)要(yao)(yao)看客戶(hu)的(de)(de)產(chan)品(pin)性質，單(dan)純來說肯定(ding)是(shi)直接沖(chong)到袋子(zi)里(li)比較好(hao)，這樣置(zhi)換(huan)的(de)(de)又純還能省(sheng)不少氣源，但是(shi)大(da)家(jia)一(yi)定(ding)要(yao)(yao)考慮(lv)好(hao)自(zi)己產(chan)品(pin)性質。如(ru)果產(chan)品(pin)是(shi)顆粒，我們可(ke)以采取起初(chu)(chu)一(yi)種(zhong)方法(fa)(fa)直接讓充(chong)(chong)氣嘴到袋子(zi)里(li)進(jin)行(xing)(xing)充(chong)(chong)氣，但是(shi)如(ru)果你的(de)(de)產(chan)品(pin)是(shi)粉末狀的(de)(de)就不能用(yong)起初(chu)(chu)一(yi)種(zhong)方法(fa)(fa)了，需要(yao)(yao)第二種(zhong)在真空室(shi)充(chong)(chong)氣利(li)用(yong)壓(ya)力差(cha)充(chong)(chong)滿(man)(man)袋子(zi)。可(ke)是(shi)客戶(hu)又要(yao)(yao)要(yao)(yao)求達到一(yi)定(ding)比例的(de)(de)殘氧量，這就很矛(mao)盾了。
