真空包裝機廠的(de)真(zhen)空(kong)(kong)包裝機增加(jia)充(chong)(chong)氣功能是(shi)(shi)(shi)(shi)有兩種方(fang)式，一種是(shi)(shi)(shi)(shi)氣嘴直接(jie)伸到產品(pin)袋(dai)子(zi)里面進行充(chong)(chong)氣的(de)，另一種是(shi)(shi)(shi)(shi)把(ba)要充(chong)(chong)的(de)氣體先充(chong)(chong)滿整(zheng)個(ge)真(zhen)空(kong)(kong)室(shi)，然后靠負壓(ya)差充(chong)(chong)滿袋(dai)子(zi)。那究竟采用(yong)哪(na)種方(fang)式充(chong)(chong)氣好呢，這里主要看客戶的(de)產品(pin)性(xing)(xing)質，單(dan)純來(lai)說肯定(ding)(ding)是(shi)(shi)(shi)(shi)直接(jie)沖到袋(dai)子(zi)里比較好，這樣(yang)置換的(de)又(you)純還能省不少氣源，但是(shi)(shi)(shi)(shi)大家一定(ding)(ding)要考(kao)慮好自(zi)己產品(pin)性(xing)(xing)質。如果(guo)產品(pin)是(shi)(shi)(shi)(shi)顆粒，我們可以(yi)采取起初一種方(fang)法直接(jie)讓充(chong)(chong)氣嘴到袋(dai)子(zi)里進行充(chong)(chong)氣，但是(shi)(shi)(shi)(shi)如果(guo)你的(de)產品(pin)是(shi)(shi)(shi)(shi)粉(fen)末狀的(de)就不能用(yong)起初一種方(fang)法了，需要第二(er)種在真(zhen)空(kong)(kong)室(shi)充(chong)(chong)氣利(li)用(yong)壓(ya)力(li)差充(chong)(chong)滿袋(dai)子(zi)。可是(shi)(shi)(shi)(shi)客戶又(you)要要求(qiu)達(da)到一定(ding)(ding)比例的(de)殘氧量，這就很矛盾了。
