2023 Development trend of China’s Vacuum packing industry
Vacuum packing, also known as vacuum packaging, is to extract all the air in the packaging container and seal it to maintain the bag in a highly reduced pressure state. The lack of air is equivalent to the effect of hypoxia, making microorganisms have no living conditions, so as to achieve the purpose of fresh food and no disease and decay. Applications include Vacuum packing in plastic bags, aluminum foil packaging, glassware, plastic and composite material packaging, etc. Packaging materials can be selected based on the type of item.
In addition to the oxygen removal and quality assurance functions of Vacuum packing, the main functions of vacuum inflatable packaging are compression resistance, gas blocking and fresh-keeping, which can effectively maintain the original color, aroma, taste, shape and nutritional value of food for a long time. In addition, many foods are not suitable for Vacuum packing and must be packaged with vacuum inflatable packaging. Such as crispy and fragile food, food that is prone to clumping, food that is prone to deformation and oil loss, food with sharp edges or high hardness that can puncture packaging bags, etc.
Vacuum packing can save cost by keeping food for a longer time. After vacuum inflatable packaging of food, the air pressure inside the packaging bag is greater than the atmospheric pressure outside the packaging bag, which can effectively prevent food from being crushed and deformed under pressure without affecting the appearance and printing decoration of the packaging bag.
In the food industry, Vacuum packing is widely used, and various cooked products such as chicken legs, ham, sausage, grilled fish slices, beef jerky, etc; More and more Vacuum packing is used in pickles, such as various Pickled vegetables, bean products, preserved fruits and other foods that need to be kept fresh. The food after Vacuum packing has a long shelf life, greatly extending the shelf life of food.
At present, China is the world’s largest packaging production and consumption country, with its products accounting for over 30% of the packaging industry. In recent years, with the development of the economy and the continuous improvement of people’s living standards, new packaging products, especially those closely related to human health, are increasingly receiving people’s attention. In the future, portable products will have great development space.
Vacuum packing film is a kind of product packaging method that seals after the product is put into the bag and the air in the bag is extracted. Some oil rich foods that are easy to deteriorate after being exposed to oxygen in the air for a long time, such as bittern products, ham, grilled fish, Peking duck, Dezhou braised chicken, etc., must choose Vacuum packing bags, preferably Vacuum packing bags cooked at high temperature.
The Vacuum packing film technology in China was developed in the early 1980s, while the vacuum inflatable packaging technology began to be used in a small amount in the early 1990s. With the promotion of small packaging and the development of supermarkets, its scope of application is becoming more and more extensive, and some will gradually replace hard packaging. The prospect is very promising.
Vacuum packing products have been widely used in people’s lives. Vacuum packing products have many advantages, such as quality preservation, anti-corrosion and rust prevention, small space occupation, easy to carry and so on. food packing machine has been widely used in all walks of life and is welcomed by everyone. With the continuous development of science and technology and the continuous improvement of people’s living standards, Vacuum packing technology
