  • 產品概述

真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong),這一術(shu)語譯自拉丁文vacuo,其意義是(shi)虛無(wu)。其實真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)應理解為氣體(ti)較稀薄的(de)空(kong)(kong)(kong)(kong)(kong)間。在(zai)指定(ding)的(de)空(kong)(kong)(kong)(kong)(kong)間內,低于一個大氣壓力(li)的(de)氣體(ti)狀態統稱為真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)。真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)狀態下氣體(ti)稀薄程度(du)稱為真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)度(du)(degreeofvacuum),通(tong)常用壓力(li)值表示(shi)。因(yin)此真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)包(bao)(bao)裝(zhuang)(zhuang)(zhuang)(zhuang)實際上(shang)不是(shi)完全(quan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)的(de),采用真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)包(bao)(bao)裝(zhuang)(zhuang)(zhuang)(zhuang)技術(shu)包(bao)(bao)裝(zhuang)(zhuang)(zhuang)(zhuang)的(de)食品容器內的(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)度(du)通(tong)常在(zai)600-1333Pa。所以(yi),又(you)將真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)包(bao)(bao)裝(zhuang)(zhuang)(zhuang)(zhuang)稱為減壓包(bao)(bao)裝(zhuang)(zhuang)(zhuang)(zhuang)或排(pai)氣包(bao)(bao)裝(zhuang)(zhuang)(zhuang)(zhuang)。
