  • 產品概述

真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong),這(zhe)一術(shu)(shu)語譯自(zi)拉丁文vacuo,其(qi)意(yi)義(yi)是虛無(wu)。其(qi)實真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)應理解為氣(qi)(qi)體(ti)較(jiao)稀薄(bo)的空(kong)(kong)(kong)(kong)(kong)間。在指定的空(kong)(kong)(kong)(kong)(kong)間內,低于(yu)一個大氣(qi)(qi)壓(ya)力(li)的氣(qi)(qi)體(ti)狀(zhuang)態(tai)統稱為真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)。真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)狀(zhuang)態(tai)下氣(qi)(qi)體(ti)稀薄(bo)程度稱為真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)度(degreeofvacuum),通常用(yong)(yong)壓(ya)力(li)值表示。因此(ci)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)包裝(zhuang)實際上不是完全真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)的,采用(yong)(yong)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)包裝(zhuang)技(ji)術(shu)(shu)包裝(zhuang)的食品容(rong)器(qi)內的真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)度通常在600-1333Pa。所以,又將真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)包裝(zhuang)稱為減(jian)壓(ya)包裝(zhuang)或排(pai)氣(qi)(qi)包裝(zhuang)。
