  • 產品概述

真(zhen)(zhen)(zhen)空(kong)(kong)(kong),這一術語譯自(zi)拉丁文vacuo,其(qi)意義是虛無(wu)。其(qi)實真(zhen)(zhen)(zhen)空(kong)(kong)(kong)應理解為(wei)氣(qi)(qi)體較稀薄(bo)的(de)(de)空(kong)(kong)(kong)間(jian)。在指(zhi)定的(de)(de)空(kong)(kong)(kong)間(jian)內,低(di)于一個大氣(qi)(qi)壓(ya)(ya)力的(de)(de)氣(qi)(qi)體狀態(tai)統稱(cheng)為(wei)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)。真(zhen)(zhen)(zhen)空(kong)(kong)(kong)狀態(tai)下氣(qi)(qi)體稀薄(bo)程度(du)(du)稱(cheng)為(wei)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)度(du)(du)(degreeofvacuum),通(tong)常(chang)用(yong)壓(ya)(ya)力值(zhi)表示。因(yin)此真(zhen)(zhen)(zhen)空(kong)(kong)(kong)包裝(zhuang)(zhuang)實際(ji)上不(bu)是完(wan)全真(zhen)(zhen)(zhen)空(kong)(kong)(kong)的(de)(de),采用(yong)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)包裝(zhuang)(zhuang)技術包裝(zhuang)(zhuang)的(de)(de)食品容器內的(de)(de)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)度(du)(du)通(tong)常(chang)在600-1333Pa。所以,又(you)將真(zhen)(zhen)(zhen)空(kong)(kong)(kong)包裝(zhuang)(zhuang)稱(cheng)為(wei)減壓(ya)(ya)包裝(zhuang)(zhuang)或(huo)排氣(qi)(qi)包裝(zhuang)(zhuang)。
