真空包裝機廠的真(zhen)(zhen)空(kong)(kong)包裝機增加充(chong)氣(qi)(qi)功(gong)能是(shi)(shi)有兩(liang)種(zhong)方式，一(yi)種(zhong)是(shi)(shi)氣(qi)(qi)嘴(zui)直(zhi)接(jie)伸到(dao)產品(pin)(pin)袋(dai)子(zi)里(li)面進行(xing)充(chong)氣(qi)(qi)的，另一(yi)種(zhong)是(shi)(shi)把要充(chong)的氣(qi)(qi)體先充(chong)滿整個真(zhen)(zhen)空(kong)(kong)室，然后(hou)靠負壓差(cha)充(chong)滿袋(dai)子(zi)。那(nei)究竟采用(yong)哪種(zhong)方式充(chong)氣(qi)(qi)好呢，這里(li)主要看客戶的產品(pin)(pin)性質(zhi)，單純(chun)來(lai)說肯定(ding)是(shi)(shi)直(zhi)接(jie)沖(chong)到(dao)袋(dai)子(zi)里(li)比較好，這樣置換的又(you)純(chun)還(huan)能省不(bu)少氣(qi)(qi)源，但(dan)是(shi)(shi)大家一(yi)定(ding)要考慮好自己產品(pin)(pin)性質(zhi)。如(ru)果產品(pin)(pin)是(shi)(shi)顆粒(li)，我們可(ke)以(yi)采取起初一(yi)種(zhong)方法直(zhi)接(jie)讓充(chong)氣(qi)(qi)嘴(zui)到(dao)袋(dai)子(zi)里(li)進行(xing)充(chong)氣(qi)(qi)，但(dan)是(shi)(shi)如(ru)果你的產品(pin)(pin)是(shi)(shi)粉末狀的就不(bu)能用(yong)起初一(yi)種(zhong)方法了(le)，需要第二種(zhong)在真(zhen)(zhen)空(kong)(kong)室充(chong)氣(qi)(qi)利用(yong)壓力(li)差(cha)充(chong)滿袋(dai)子(zi)。可(ke)是(shi)(shi)客戶又(you)要要求達到(dao)一(yi)定(ding)比例的殘氧量，這就很矛(mao)盾了(le)。
