真空包(bao)裝機廠的(de)真(zhen)空(kong)包(bao)裝機增加充(chong)(chong)(chong)(chong)氣(qi)(qi)功能是(shi)有兩(liang)種(zhong)方(fang)式(shi)，一(yi)(yi)種(zhong)是(shi)氣(qi)(qi)嘴直接(jie)伸到(dao)產品(pin)袋子(zi)里(li)面進(jin)行充(chong)(chong)(chong)(chong)氣(qi)(qi)的(de)，另一(yi)(yi)種(zhong)是(shi)把要(yao)充(chong)(chong)(chong)(chong)的(de)氣(qi)(qi)體先(xian)充(chong)(chong)(chong)(chong)滿(man)整個(ge)真(zhen)空(kong)室，然后靠(kao)負壓(ya)差充(chong)(chong)(chong)(chong)滿(man)袋子(zi)。那究竟采用(yong)哪種(zhong)方(fang)式(shi)充(chong)(chong)(chong)(chong)氣(qi)(qi)好呢，這里(li)主要(yao)看客戶的(de)產品(pin)性質，單純來說肯定(ding)是(shi)直接(jie)沖(chong)到(dao)袋子(zi)里(li)比較好，這樣(yang)置換(huan)的(de)又純還能省(sheng)不少氣(qi)(qi)源，但是(shi)大(da)家一(yi)(yi)定(ding)要(yao)考慮好自(zi)己(ji)產品(pin)性質。如(ru)果產品(pin)是(shi)顆粒，我們(men)可(ke)以采取起初(chu)一(yi)(yi)種(zhong)方(fang)法(fa)直接(jie)讓充(chong)(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋子(zi)里(li)進(jin)行充(chong)(chong)(chong)(chong)氣(qi)(qi)，但是(shi)如(ru)果你(ni)的(de)產品(pin)是(shi)粉末(mo)狀的(de)就不能用(yong)起初(chu)一(yi)(yi)種(zhong)方(fang)法(fa)了，需(xu)要(yao)第二種(zhong)在真(zhen)空(kong)室充(chong)(chong)(chong)(chong)氣(qi)(qi)利用(yong)壓(ya)力(li)差充(chong)(chong)(chong)(chong)滿(man)袋子(zi)。可(ke)是(shi)客戶又要(yao)要(yao)求達到(dao)一(yi)(yi)定(ding)比例的(de)殘氧量，這就很矛(mao)盾了。
