真(zhen)(zhen)(zhen)空(kong)(kong),這一術語(yu)譯自拉丁文vacuo,其意義(yi)是虛(xu)無。其實真(zhen)(zhen)(zhen)空(kong)(kong)應(ying)理解為氣體較(jiao)稀薄的(de)空(kong)(kong)間(jian)。在指定的(de)空(kong)(kong)間(jian)內,低于一個大氣壓力(li)的(de)氣體狀態(tai)統稱為真(zhen)(zhen)(zhen)空(kong)(kong)。真(zhen)(zhen)(zhen)空(kong)(kong)狀態(tai)下氣體稀薄程度稱為真(zhen)(zhen)(zhen)空(kong)(kong)度(degreeofvacuum),通(tong)常(chang)用(yong)壓力(li)值(zhi)表示(shi)。因此(ci)真(zhen)(zhen)(zhen)空(kong)(kong)包(bao)(bao)(bao)裝實際上不是完全真(zhen)(zhen)(zhen)空(kong)(kong)的(de),采用(yong)真(zhen)(zhen)(zhen)空(kong)(kong)包(bao)(bao)(bao)裝技術包(bao)(bao)(bao)裝的(de)食品(pin)容器內的(de)真(zhen)(zhen)(zhen)空(kong)(kong)度通(tong)常(chang)在600-1333Pa。所以,又將真(zhen)(zhen)(zhen)空(kong)(kong)包(bao)(bao)(bao)裝稱為減(jian)壓包(bao)(bao)(bao)裝或排氣包(bao)(bao)(bao)裝。
