真空包裝機廠的(de)(de)真(zhen)空包裝機增加充(chong)(chong)(chong)氣功(gong)能是(shi)(shi)(shi)有兩種(zhong)(zhong)方(fang)式(shi)，一(yi)種(zhong)(zhong)是(shi)(shi)(shi)氣嘴直接(jie)伸(shen)到產(chan)(chan)品袋(dai)(dai)子(zi)(zi)里(li)(li)(li)面進行(xing)充(chong)(chong)(chong)氣的(de)(de)，另一(yi)種(zhong)(zhong)是(shi)(shi)(shi)把要充(chong)(chong)(chong)的(de)(de)氣體(ti)先充(chong)(chong)(chong)滿整個(ge)真(zhen)空室(shi)，然后靠負壓(ya)差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。那(nei)究竟采用哪種(zhong)(zhong)方(fang)式(shi)充(chong)(chong)(chong)氣好(hao)呢，這(zhe)(zhe)里(li)(li)(li)主要看客(ke)(ke)戶的(de)(de)產(chan)(chan)品性質，單純來說肯定(ding)是(shi)(shi)(shi)直接(jie)沖(chong)到袋(dai)(dai)子(zi)(zi)里(li)(li)(li)比(bi)較(jiao)好(hao)，這(zhe)(zhe)樣置(zhi)換(huan)的(de)(de)又(you)純還能省不少氣源(yuan)，但(dan)是(shi)(shi)(shi)大家一(yi)定(ding)要考(kao)慮好(hao)自(zi)己產(chan)(chan)品性質。如(ru)果(guo)產(chan)(chan)品是(shi)(shi)(shi)顆粒，我們可以采取起(qi)初一(yi)種(zhong)(zhong)方(fang)法(fa)直接(jie)讓(rang)充(chong)(chong)(chong)氣嘴到袋(dai)(dai)子(zi)(zi)里(li)(li)(li)進行(xing)充(chong)(chong)(chong)氣，但(dan)是(shi)(shi)(shi)如(ru)果(guo)你的(de)(de)產(chan)(chan)品是(shi)(shi)(shi)粉末狀的(de)(de)就不能用起(qi)初一(yi)種(zhong)(zhong)方(fang)法(fa)了，需要第二種(zhong)(zhong)在真(zhen)空室(shi)充(chong)(chong)(chong)氣利用壓(ya)力差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。可是(shi)(shi)(shi)客(ke)(ke)戶又(you)要要求(qiu)達到一(yi)定(ding)比(bi)例的(de)(de)殘氧(yang)量，這(zhe)(zhe)就很(hen)矛盾了。
