Shredded meat food packaging bags of air tightness

Why shredded meat food packaging bags for air tightness test shredded meat food is pork, lean meat, chicken, fish, pounding mixing together, and then dried to remove moisture, nutrition is high, easy to oxidation. So pork floss of food store need from moisture, oxygen, choose packaging must air tightness good, otherwise feel pork floss prone to damp, gone mouldy, and other issues. In order to choose a good air tightness good bags, air tightness test is a must. What is air tightness of the packaging bags? Air tightness refers to the bags insulate the external and internal environment are degree, makes no internal and external communication on gas exchange, almost negligible or communication. Air tightness is about the packing of the key factors on the quality of the content, if with poor sealing of the packaging bags, packaging bags of internal gas content or composition is easy to change, such as packing external gas penetrating into the internal or packaging filling gas is lost, the above phenomenon could lead to lower product quality. Packing bag air tightness is related to material quality, heat sealing effect. Problem is relatively hidden and bags, it may be difficult to find to the naked eye, so difficult to found and handled in time before they go out, so in the process of circulation, storage for a long time after the factory due to the slow leakage, leakage and package contents appear moldy, agglomerate, bulge bag, such as quality problem, therefore the enterprise bear big risk and economic loss. This is shredded meat food packaging to the cause of the air tightness test, in order to reduce enterprise losses and risks. Shredded meat food packaging bags of testing case analysis in the market, there are a lot of seal tester, by tester, can easily understand the airtight performance of the packaging bags. This tester is shredded meat food packaging produced negative pressure to the external environment, the internal pressure is greater than the outside, the gas will stay outward. See how many cases, in the negative pressure gas to escape, air leakage. Three test shredded meat food packaging bags, 1 in - 34. 5 pa occurs leakage, the other two in in - Under the 90 pa, still not leak. Thus, able to withstand the negative pressure is higher, the air tightness is the better of the packaging bags.
