The packaging material of food packaging bag
s is the basis of food bag
s, which carry food label information and protect food safety. Either way, the packaging material is crucial. Our manufacturers will provide customers with food packaging hygiene inspection reports with the goods, which also includes the safety and hygiene information of the packaging materials. In fact, another important information about the packaging material is the storage period. If the storage period exceeds the storage period and has not been re-inspected, it cannot be used. Naturally, there is no safety and hygiene at all. Therefore, it is sufficient for the food manufacturer to obtain the inspection report of the packaged product. Because plastic, aluminum foil and other packaging materials are in motion, they will age and change. There are also strict requirements for their storage environment after production, because the environment can affect their performance. Therefore, the national standard for the packaging materials of food packaging bags“storage period”Regulation. Why should it be? Because the aging speed of packaging materials has a great relationship with the storage environment, those that can not be used during the application storage period can be re-inspected. The following is the comparison table of the storage period of the packaging materials of various food packaging bags. The name of the packaging material should have the storage period. BOPP0.5 years 0.3 years CPP0.5 years 0.3 years PE blown film 2 years 1 year BOPA1 year 0.5 years composite packaging material 1 year 0.5 years Speaking of food packaging bags, the packaging materials have a shelf life, especially many food packaging bags are All composite bags, many friends will ask, what if the shelf life of the food exceeds one year. Here we have to distinguish the difference between the storage period and the shelf life. After the shelf life, most of them can no longer be eaten; after the storage period, most of them can still be used if they are well preserved. And when the food packaging bag is sealed, the packaging material of the inner film is well preserved. Its service life is much longer than the shelf life of the packaged food. It is not possible to compare the due storage period of the food packaging bag packaging material with the shelf life of the food. The above is the summary of the storage period of food packaging bag packaging materials for everyone, I hope it will help you who are concerned about food packaging bag packaging materials.
