Food is indispensable and irreplaceable in our lives, so have you ever thought about why the food we see is packaged.<\/p>\n

The necessity of food packaging<\/h2>\n

From the point of view of the steps of food production and product sales, the purpose of food packaging is mainly to prevent food from spoiling, and at the same time, the most important thing is to ensure the quality of food.\u00a0Packaging is an important medium to ensure food quality and reduce food waste, and it is also an effective way to reduce the addition of preservatives in the food production process.\u00a0The packaging has important functions of installing food, preventing food from spoiling, appearing damage and avoiding infringement.\u00a0At the same time, packaging can also provide consumers and sales personnel with necessary relevant information, and convey to them the relevant characteristics of the product and the nutritional information of the food in the package.<\/p>\n

Food packaging is not only closely related to the health of consumers, but also to the reputation of the company; it can also prevent microbial and dust pollution.\u00a0Although manufacturers are now paying more and more attention to the sanitation of production lines, suspended dust still cannot be completely avoided and isolated.\u00a0In the process from product production, packaging to sales, there are many opportunities for food to come into contact with people, air, and various tools and equipment. This also shows that food is actually very susceptible to contamination by microorganisms and dust.\u00a0Packaging food is also responsible to consumers. If consumers eat heavily contaminated food, it will cause food poisoning.\u00a0With packaging, a reasonable packaging design can simplify transportation conditions and extend the time for goods to be placed on the shelf, which is also a way to reduce waste.\u00a0Therefore, food must be packaged to prevent secondary pollution.<\/p>\n

Causes of air leakage in packaging swelling bags<\/h2>\n

Good food packaging not only requires attention to design, but more importantly, the packaging effect must be paid attention to.\u00a0Packing swelling or leaking is the most common packaging defect in food vaccum packaging.\u00a0For vacuum packaging, air tightness is an important criterion for considering this packaging.<\/p>\n

The reasons for bag expansion or air leakage of vacuum packaging may be as follows:<\/p>\n

The first is that the bacteria in the vacuum packaging bag multiply and produce gas, which is also one of the main reasons for the flatulence of the vacuum packaging bag.\u00a0On the premise that there is no quality problem in the packaging bag itself, if the food packaged in the bag is not completely sterilized, it will rapidly multiply in the bag, and the phenomenon of bag swelling will occur over time.<\/p>\n

Lax sealing is also one of the reasons.\u00a0The packaging bag sealing process is an important key in the packaging process on the packaging line.\u00a0Whether it is vacuum packaging or inflatable packaging, the requirements for packaging and sealing have never been lowered.\u00a0After the food is bagged, it will be heat-pressed and sealed in the next process of the packaging line.\u00a0The quality of this process will directly affect the air tightness of the vacuum packaging bag.\u00a0If the sealing effect of this process is not good, the sealing edge is not tight enough, it is very likely that the vacuum packaging bag will leak.\u00a0When the external air enters the packaging bag through the leaking part, the vacuum packaging will also produce bag expansion.<\/p>\n

When the storage temperature changes from time to time, condensed water will be generated in the package in an alternate hot and cold environment, which will also cause the package to look bloated.\u00a0And long-term contact between food additives and food sometimes produce gas.<\/p>\n

Packing level<\/h2>\n

Primary packaging is the layer of packaging that is in direct contact with the product.\u00a0Primary packaging is an important line of defense between the products in the package and the outside world. For fast-moving products, primary packaging is also an indispensable packaging process.\u00a0Some primary packaging needs to be discarded after the product is used up, such as some beverage bottles, potato chip bags, etc.; some primary packaging needs to be discarded at the beginning of use, such as some packaging bags for fast food sandwiches and other items.<\/p>\n

The secondary packaging is the big packaging bag that sums up many primary packagings.\u00a0To put it simply, when you buy a full box of drinks in a supermarket, the box that packs the scattered drinks in one box is the so-called secondary packaging.\u00a0Some product-related information is often printed on the secondary packaging, which can play a role in attracting buyers and promoting companies to a certain extent.<\/p>\n

The primary packaging and secondary packaging will overlap in most cases.\u00a0For many products on the market that people can see, the primary packaging is the secondary packaging.\u00a0Merchants print and advertise on primary packaging, which in turn gives primary packaging the role and function of secondary packaging.<\/p>\n

If you want to distinguish between primary packaging and secondary packaging more intuitively, you can observe the packaging of drugs.\u00a0For example, when we get a drug for the first time, the cardboard box that can be reached by both hands is the secondary packaging.\u00a0There should be relevant information about the product and the company on the secondary packaging, which will serve as a message to consumers.\u00a0The packaging of the medicine directly wrapped in the box is the primary packaging.<\/p>\n

The third-level packaging is mainly used for the transportation of goods to ensure that the goods\u00a0will not be damaged during the\u00a0transfer\u00a0from\u00a0A\u00a0to\u00a0B.\u00a0For example, in the transportation of large machinery, the wooden boxes used by the packaging machinery and the plastic film used for packaging belong to the category of tertiary packaging.<\/p>\n
