A, flexible packaging of liquid filling sealing heat seal strength testing

Heat sealing strength is an important performance index for packaging material, for any kind of liquid flexible packaging materials to make bags to packaging a wide variety of goods, packing of goods should be heat sealing to seal and packing. Sealing it is certain to should have the strength to withstand the weight of the built-in pressure, guarantee the goods not cracking in the process of circulation. Heat sealing the three major factors of heat sealing temperature, pressure, time, according to the different needs of different heat sealing.

 

二、液体包装的密封性检测Soft packing seal is also an important performance index, especially liquid filling industry, sealing also has a great influence to the quality of the product. Bad sealing is caused by leakage of the main causes of corruption in the future, serious damage to food safety. Sealing test have a variety of methods, the most commonly used method is to use the leakage test instrument, using the vacuum principle, according to the national standard in – 30 kpa, respectively, to 50 kpa, – 70 kpa to 90 kpa keep 0.5 minutes, pay attention to during the process of test sample during the period of observation of vacuum and vacuum keep leaks, observe the presence of continuous air bubbles, not to be considered when an isolated bubbles. Through the determination of the sealing to measure the quality of the bag, and then to determine the rationality of the loading process.
