A small corn is the livelihood of an entire nation. Corn is one of the three main grains in China, which can be seen everywhere in the north, and its output accounts for 38.9% of China's total grain production, which plays a pivotal role in China's agricultural production and national economy.
With the continuous improvement of people's living standards, the requirements for life are not only enough to eat and warm, the demand for quality is also getting higher and higher, and the quality requirements for corn are also constantly improving.
The nutritional value, quality and taste of fresh corn have a great relationship with the storage time after picking. Generally speaking, the freshly picked corn is the most tender and delicious. With the loss of time, the fragrance and moisture of corn will be lost, which will correspondingly affect the taste. Therefore, vacuum packaging is the most mainstream corn packaging method, which can extend the shelf life and play the role of staying fragrance. The vacuum packaging bag of corn is also a lot of attention.
Vacuum packaging bag refers to a packaging method that adds the product to the airtight packaging container, removes the air inside the container, and makes the sealed container reach a predetermined vacuum degree. Vacuum bag, also known as decompression packaging, is to remove all the air in the packaging container and seal it, maintain the bag in a highly decompression state, and the scarcity of air is equivalent to the effect of low oxygen, so that microorganisms have no living conditions, in order to achieve the purpose of fresh fruit and no disease and decay. The applications include vacuum packaging in plastic bags, aluminum foil packaging, glassware packaging, etc.
Under normal circumstances, vacuum packed corn is generally boiled with a bag, because the water is not soaked in the corn, which can ensure the original taste of the corn.
Therefore, the choice of material should be more careful, to choose high temperature cooking material, to ensure that it does not deform at high temperatures, does not produce harmful substances, Common materials include PA/PE, PA/RCPP, PET/RCPP, PET/PA/PE, PET/PA/ RCPP, PA/AL/RCPP, PET/PA/ AL/RCPP, PET/PA/ AL/RCPP. However, the aluminum foil material is relatively rare in the vacuum packaging of corn, because the price is high, and the light requirements of corn are not high.
On the other hand, transparent packaging of corn is common, because it allows consumers to clearly see the quality of corn, including length, thickness, weight, grain fullness, etc., "seeing is believing", and it is easier to narrow the distance between consumers. You can also choose to open the window design, both to ensure that consumers see the product, but also through the novel design to arouse consumer interest.
