Liquid milk needs to go through countless processes from farm to consumers. The packaging is one of the most important links. At present, the liquid milk packaging on the market is generally selected for plastic packaging and bottles, and the subdivision includes PE as the main raw material to squeeze black and white film, Treaty bag and Kangmei Box, Treasure pillow, roof ridge bag, sterile composite film, glass bottle, etc. Essence Each packaging has its own characteristics and advantages. For example, glass bottle can be used in circular, more environmentally friendly, PE black and white co -squeeze film is more cost -effective, and liquid milk uses high temperature instantaneous sterilization. About 30 days, and when it is packaged with a black and white film, the shelf life can reach about 90 days. However, we found that there will be differences in the shelf life of the same packaging liquid milk. The shelf life and actual shelf life marked by each manufacturer will be different. Why is this?
In order to ensure that liquid milk is convenient for the public to carry and eat daily, the packaging form of liquid milk is mainly small and easy to open. At the same time, in order to ensure its taste and nutritional ingredients to the greatest extent, the packaging materials used in liquid milk should also have good obstruction. In particular, oxygen in the outside world should have high resistance. Therefore, before the appearance of liquid milk packaging, strict blocking tests must be performed. Equipment and testing methods for blocking tests are the key factor that determines the quality of liquid milk packaging, and it is also an important factor in determining the quality of liquid milk.
