What problems should be paid attention to in the high barrier test of water vapor transmittance and co2 transmittance of vacuum packaging bags?

source:other news release time:2022-10-28 Hits:    

  

  Vacuum packaging bag isolation characteristics, whether it is water vapor transmittance or co2 transmittance, in the whole process of inspection and inspection results should pay attention to the following many levels:

  1. The definition of occupation rate is obtained in accordance with the standard of Fick's basic law of plastic film. For co2, except for some raw materials of oxygen therapy, it is generally in accordance with Fick's basic law.

  However, because the infiltration of water vapor and organic compounds in the whole process, and many polymers will interact with each other, so generally belong to the non-Fecker's basic law type of spread.

  2. For the vacuum packaging bag raw materials, its structure is not necessarily symmetric, so there are both positive and negative problems of the specimen. Some raw materials, polyvinylidene chloride coating process such as polyester cloth "PA", polyvinylidene chloride and the whole process or PE composite bag of its positive and negative sides of the co2 transmittance accurate measurement results are very different, sometimes even can be doubled.

  This is because in the whole process of the specific detection, the measured results are the sum of the infiltration across the specimen and the infiltration of the sealing part.

  3, in view of the adsorption force, great packaging film, water imbibition in the whole experiment process should consider its adsorption and adsorption, etc. The harm of the test results, the other should be clear general equilibrium time is longer, and even the same natural environment, through the whole process of different equilibrium state does not necessarily in the same way, in other words, not the equilibrium state of raw materials, but associated with equilibrium of natural environment, and with The whole process is related.

  Great attention should be paid to the leakage problem in the whole process of the test. All the water vapor transmittance and co2 transmittance obtained by the test are the total number of infiltration and leakage. Only under the standard of leakage can be ignored, the measured infiltration is accurate.

  In addition, packaging products and packaging are 2 different definitions, with high barrier packaging products, may not be able to produce a high barrier packaging. From the packaging product to the package, from the package to the customer's hand, in the whole process, many elements are harmful to the final isolation characteristics of the commodity.
