真空包裝機廠的真(zhen)空包裝(zhuang)機增加充(chong)(chong)(chong)氣功能是(shi)(shi)有兩種方式，一(yi)種是(shi)(shi)氣嘴直接(jie)(jie)伸到(dao)(dao)產品(pin)袋子(zi)里面進行充(chong)(chong)(chong)氣的，另一(yi)種是(shi)(shi)把要(yao)(yao)(yao)充(chong)(chong)(chong)的氣體先充(chong)(chong)(chong)滿整個真(zhen)空室(shi)(shi)，然后(hou)靠負壓差(cha)充(chong)(chong)(chong)滿袋子(zi)。那(nei)究竟采用(yong)哪種方式充(chong)(chong)(chong)氣好呢，這里主要(yao)(yao)(yao)看客戶的產品(pin)性質(zhi)，單純(chun)(chun)來說肯定(ding)(ding)是(shi)(shi)直接(jie)(jie)沖到(dao)(dao)袋子(zi)里比較好，這樣置換的又(you)純(chun)(chun)還能省(sheng)不少氣源，但是(shi)(shi)大家一(yi)定(ding)(ding)要(yao)(yao)(yao)考慮好自己產品(pin)性質(zhi)。如果產品(pin)是(shi)(shi)顆粒，我們可以采取起(qi)初(chu)一(yi)種方法(fa)直接(jie)(jie)讓充(chong)(chong)(chong)氣嘴到(dao)(dao)袋子(zi)里進行充(chong)(chong)(chong)氣，但是(shi)(shi)如果你(ni)的產品(pin)是(shi)(shi)粉末狀的就不能用(yong)起(qi)初(chu)一(yi)種方法(fa)了，需(xu)要(yao)(yao)(yao)第二種在(zai)真(zhen)空室(shi)(shi)充(chong)(chong)(chong)氣利用(yong)壓力差(cha)充(chong)(chong)(chong)滿袋子(zi)。可是(shi)(shi)客戶又(you)要(yao)(yao)(yao)要(yao)(yao)(yao)求達到(dao)(dao)一(yi)定(ding)(ding)比例的殘氧量(liang)，這就很矛(mao)盾了。
