The Leakage of MRE Package Heat Seal

May 14, 2009 - PRLog -- The leakage of MRE packages is the result of failed heat seal owing to certain factors as follows:
A. Insufficient heat seal temperature. Different temperatures are required for different parts of one package as well as for different packaging speed. The horizontal heat seal and vertical heat seal require different heat seal temperatures, which has to be taken into consideration during packaging process. Besides, for heat seal instruments, temperature control accuracy is also very important.
B. Contaminated seal places. During inserting process, the seal places of packages are usually contaminated by the contents; including liquid contamination and dust contamination.
C. Issues related to equipments and operations, such as foreign subjects in the heat seal mold, inferior heat seal pressure and unparallel heat seal mold, etc.
D. Issues related to packaging materials, such as inferior heat seal caused by extra corona discharge or excessive slipping agent.
 The above-mentioned issues can be resolved by online inspection as well as laboratory testing by Labthink PARAM MFY-01 Leak Tester and LSSD-01 Leak and Seal Strength Detector for leakage.
