In recent years, the rapid development of China's pharmaceutical and food hygiene industry has provided a vast market space for paper packaging. At present, kraft paper and cardboard are widely used in the packaging of medicines, cosmetics, electronic products, clothing, toys, gifts, and tobacco. Aseptic paper packaging is popular in the food and beverage industry.
Sterile paper packaging is composed of cardboard, plastic and aluminum film. It is usually composed of 6 layers, 73% of paper, 20% of plastic, 5% of aluminum, and 2% of other printing inks and coatings. Part of the chemical thermomechanical pulp is usually added to the board and there is a thin layer outside.
Sterile paper packaging can ensure that the nutrients and tastes of foods are preserved and the shelf life is greatly extended. The aseptic paper packaging composite packaging material and vacuum state can protect the product from light, gas, odor and microbes, so that the food does not need to add preservatives, transportation, storage without refrigeration. The aseptically packaged product has a brick-like shape, which makes the space utilization of the product high and the weight light, so the cost is low. More importantly, aseptic paper packaging meets the trend of environmental protection packaging.
Industry analysts pointed out that due to the prominent advantages of sterile paper packaging materials, there is a good development prospect in the Chinese market. China's milk is mainly produced in the north, and milk consumption in the south is greater than that in the north, so the normal temperature packaging of milk is particularly important. In 2011, the total output value of the national dairy industry reached 236.1 billion yuan, and the consumption of liquid dairy products reached approximately 20.9 million tons. It is estimated that at the rate of 10% per year, the consumption of liquid dairy products in China will reach 30 million tons in 2015. Only 20% of them are packaged in sterile paper, and 14.8 billion pieces of sterile paper are needed each year. In addition, with the continuous improvement of people’s living standards, the demand for fruit juice drinks and tea drinks is increasing year by year. According to this, experts predict that Demand for aseptic paper packaging grows by 20% to 30% annually.
Experts say that relevant companies need to introduce advanced equipment, break monopoly, and enter the high-grade sterile paper packaging market as soon as possible.
