What are the process thinking of multi-grain packaging?

"Rice flow fat corn white". Grains and miscellaneous grains have been the source of nutrition for Chinese people for thousands of years, and grain harvest has been the ardent expectation of Chinese farmers for thousands of years. At the time of harvest, the rich and shiny rice is the best reward and reward for the labor writer.

Today, grains are still the protagonist. However, with the change of consumption situation, people's needs gradually transition from eating enough to eating well, and the quality requirements of urban people are getting higher and higher. In addition to the origin and variety, the storage of cereals has also become important.

In the dog days of summer, the temperature is high and humid, and the rice, noodles and grains stored at home are particularly susceptible to insects, which greatly reduces the shelf life of food. Like the milled rice we usually eat, these fine grains, frequent consumption and fast consumption, rarely appear rot phenomenon, but for some cereals with slow consumption, once improperly stored, it is easy to deteriorate, and it is a pity to throw away, especially to catch up with the humid and sultry environment, but also to provide a breeding ground for many bugs, many cereals either rot or insects. Therefore, in the choice of storage methods, people are more careful and cautious.

After continuous selection, elimination and optimization, plastic packaging stands out and has become the most common packaging method. So what are the advantages of plastic packaging?

First, the biggest advantage of plastic bag packaging compared with other packaging forms is its lower cost (including materials and filling equipment), there is a larger price advantage, and the price has largely played a leading role. Lower unit price makes it easier to reduce costs.

Second, compared with the past grains and coarse grains mostly use woven bags, non-woven bags packaging, packaging grains and coarse grains with plastic bags can effectively moisture-proof, mildew proof, anti-odor. The moisture resistance, barrier property and processing formability of plastic bags are relatively sudden, in the storage and transportation process of products, plastic bags can be useful to avoid product leakage, scattering, loss, shortening, discoloration and so on.

Third, compared with traditional plastic packaging bags such as metal, ceramics, and glass, the lightness of plastic packaging bags is unmatched by other information.

Fourth, at present, high-end brands usually use vacuum plastic packaging, which can isolate oxygen, effectively extend the shelf life of cereals, and prevent the invasion and reproduction of bacteria to ensure food safety and hygiene. In addition, the vacuumed packaging bag will make the volume of the product smaller and easier to store and transport. And some use four-sided sealed vacuum bags to bag grains and coarse grains, because of the mold, so that the goods show a very regular shape, easy to place and store.

Fifth, packaging grains with plastic bags, you can choose smaller specifications of packaging, such as 500g multi-grain packaging bags, 1000g multi-grain packaging bags, etc., this small specification of plastic packaging bags is conducive to enterprises to carry out more subdivision of goods, open up a larger market. Moreover, small size packaging can also be convenient for consumers to buy and use, and there is no need to worry about too much damage in storage.
