Why your snacks are always affected with damp?
Why the seafood you buy is so hard to keep fresh?
Why your favorite tea is easy to get moisture?
And why your refrigerator is often full of mixing smell?
Actually, In our daily life, unscientific food preservation methods not only cause waste and pollution, but also endanger our health.

Food decays because oxygen and other components in the air, or microorganisms such as bacteria, have a chemical reaction with some components in food. To extend the shelf life of food is to delay the rate of chemical reaction as much as possible. There are many methods we can approach to, such as temperature control, air conditioning, sterilization, vacuum pumping and so on. For every 10℃ of temperature rise, the speed of chemical reaction will increase by 2-4 times. According to this calculation, a food can be stored for one day at 25 ℃, then it can be stored for about one week at 0-4 ℃.

Nowadays, many foods’ preservation is very relying on the cold chain, which not only accurately controls the temperature, but also maintains the low temperature in every steps. However, generally cooked food has a large moisture content and rich nutrition, which is easy to breed bacteria. If it is not sterilized after vacuuming and does not use good barrier packaging materials, it’s so hard to prolong the shelf life of food. Today’s fresh-locking of food requires the combination of a variety of different technologies. It is unrealistic to operate a technology in isolation to achieve fresh preservation.

Take one very common food in life for example, peanuts.

Peanuts are rich in unsaturated fatty acids and antioxidants. They often go bad when they are placed randomly and then taste strange, that is, many components are oxidized. In the past, we could only tie the bag as tightly as possible to delay deterioration. But now, the preservation is quite closely linked to the package.

When peanuts are still growing, they should start pest control. pests proof during storage after picking. When transported to the processing plant, the cold chain should be added. Vacuum pumping, sterilization and high barrier packaging are required during processing. Moreover, high barrier packaging is an important guarantee to ensure the effectiveness of all previous fresh-keeping and quality assurance processes.

Supamid Series Film Product – core film for packaging material, its excellent barrier performance is many times higher than that of ordinary materials, which can effectively block the air from entering the packaging, prevent the smell from spreading out, prevent food oxidation, and maintain the color, flavor and nutritional value of food.

The use temperature range of Supamid Series Film Product is very wide, and its mechanical properties are also excellent, so that can guarantee that the food packaging is not easy to be damaged in high stacking, violent storage and transportation or large temperature difference and so on, and make the food keep fresh for a long time.

Various technologies for food fresh-locking and quality assurance can not be used in isolation. In the last packaging process, it is very important to select a good packaging material.
