真空包裝機廠的真空(kong)包(bao)裝機(ji)增加充(chong)氣功能(neng)是(shi)有(you)兩種(zhong)方式，一(yi)(yi)(yi)種(zhong)是(shi)氣嘴(zui)直(zhi)接(jie)伸到(dao)(dao)產(chan)(chan)品袋(dai)子里(li)(li)面進(jin)(jin)行(xing)(xing)充(chong)氣的，另(ling)一(yi)(yi)(yi)種(zhong)是(shi)把要充(chong)的氣體先(xian)充(chong)滿整個真空(kong)室(shi)，然后靠負壓差充(chong)滿袋(dai)子。那究竟采(cai)(cai)用哪種(zhong)方式充(chong)氣好呢，這里(li)(li)主要看客(ke)戶的產(chan)(chan)品性(xing)質，單純來說(shuo)肯定是(shi)直(zhi)接(jie)沖(chong)到(dao)(dao)袋(dai)子里(li)(li)比較好，這樣置換的又(you)純還能(neng)省不少氣源，但是(shi)大家一(yi)(yi)(yi)定要考慮(lv)好自(zi)己(ji)產(chan)(chan)品性(xing)質。如果產(chan)(chan)品是(shi)顆粒，我們(men)可(ke)以采(cai)(cai)取起初(chu)(chu)一(yi)(yi)(yi)種(zhong)方法(fa)直(zhi)接(jie)讓(rang)充(chong)氣嘴(zui)到(dao)(dao)袋(dai)子里(li)(li)進(jin)(jin)行(xing)(xing)充(chong)氣，但是(shi)如果你的產(chan)(chan)品是(shi)粉末狀的就不能(neng)用起初(chu)(chu)一(yi)(yi)(yi)種(zhong)方法(fa)了，需(xu)要第二種(zhong)在真空(kong)室(shi)充(chong)氣利用壓力(li)差充(chong)滿袋(dai)子。可(ke)是(shi)客(ke)戶又(you)要要求達到(dao)(dao)一(yi)(yi)(yi)定比例的殘氧量，這就很矛盾(dun)了。
