Food packing:
(1) the effect of keeping value: food by light, oxygen in the process of storage, the action of enzyme, temperature will be fat oxidation and Browning, vitamin and protein denaturation, pigment decomposition, moisture absorption and microbial pollution and other issues, so food packaging can control the above four factors first to extend the shelf life of food, to keep the food nutrition and quality. This is also the most basic and important function of food packaging.
(2) Convenient storage and transportation: Because of the different nature of raw materials, all kinds of food are easy to be squeezed in the process of transportation, collision and other effects make food quality decline. So different food packaging for food in the transportation process to provide a certain buffer protection, such as the mechanical impact resistance of cans, if vegetables with corrugated box buffer performance, and like our common thermal shrinkage film packaging, because of its compact packaging, compared with other packaging more space saving and widely used.
(3) Promote sales: When we see a wide variety of food in shopping malls, we not only focus on the quality of the products, but also the food packaging will attract consumers to a certain extent. We prefer to buy food that is beautifully packaged rather than poorly packaged. As an example, why the coconut palm coconut juice brand can have an advantage in the competition of similar products, in addition to its product quality, but also under a lot of idea on the packaging (his coconut milk packaging is a bit like our small ads posted by the road, the purpose is to highlight a key: pure natural coconut juice)
(4) promoting the value of goods: It is obvious that packaged goods have higher value, the same food, packaging will give additional value to the product. From another point of view, in recent years, there have also been put forward excessive packaging, and in the food production process pay too much attention to the packaging of food (moon cakes and other festival gifts), which is also worth our deep thinking about a problem.
