As the saying goes: "People rely on clothes to rely on saddles." For things, if the packaging is exquisite and pleasing to the eye, it will inspire purchase. For example, canned food, to open up the market, requires technology upgrades, product replacement, but also to solve the "can not eat delicious mouth open" problem. According to reports, some domestic canned enterprises have introduced advanced soft canned production lines from the United States, Japan, Italy, and other countries; some have also developed a variety of easy-open canned special-shaped cans. Canned companies started to move and improving packaging is a good sign. Which packaging is better, metal packaging, glass packaging, or flexible packaging?
Metal packaging technology to upgrade
Metal packaging products mainly include aluminum two-piece cans, three-piece tin cans, and canned food cans. Compared to flexible packaging, the technology is relatively mature. Its products have the characteristics of long shelf life, easy carry and collision resistance, and easy to counterfeit (which is also the most important point). China's metal packaging has reached the level of similar products in advanced countries: two cans have about 25 production lines, annual production capacity of about 11 billion or so; tinplate three-piece can manufacturing equipment has various types of imported and domestic automatic resistance There are more than 500 welding machines and nearly 300 production lines. Its products supply approximately 4 billion beverages industry a year, and approximately 3.8 billion canned food products. About 200 crown cap production lines nationwide and more than 90% of equipment are imported from abroad. , The annual market demand is 35 billion; the iron-printing equipment and iron-coated equipment have more than 500 production lines across the country, with half of the imported equipment and domestic equipment, printing more than 15 billion times annually, and more than 300 sets of imported equipment for various bottle caps (sets The annual demand for tinplate in the whole industry is about 1.4 million tons.
With the increase of domestic tinplate production capacity, imports of tinplate will gradually decrease and they will be self-sufficient soon, but some high-end products still need a small amount of imports.
Although domestic growth is rapid, there is still a considerable gap compared with foreign countries. According to reports, there are currently nearly 200 billion tinplate cans and food cans in the world, more than 200 billion aluminum cans, and about 10 billion aerosol cans. Asian beverage cans and food cans have grown at a rate of 250% for two-piece cans, 63% for three-piece cans, and 71% for food cans.
From the analysis of per capita consumption, there is still a large market space for metal packaging in China. The key to developing the market is to reduce the cost of metal cans. In order to reduce costs, the foreign can industry has generally adopted two methods of reducing the thickness of aluminum plates and improving the shape of cans. The thickness of each aluminum plate in the US tank factory is reduced by 0.01mm, which can save about US$0.22 per thousand cans. The shrinkage of the easy-opening neck from 404 to 401 can save 12.5% ​​of the material; the can neck can be reduced from 206 necks to 204. Saving material consumption by 6.7%, and then reduced to 202, it can save 13.6%. These practices can be used for reference by the domestic tank industry.
For canners, once the cost of metal packaging is reduced, and the difficulty of opening up is solved, it will bring about a leap in metal packaging. It is because of the above reasons that some foreign companies have come to China to invest in the metal packaging industry, and domestic metal packaging companies can not lag behind.
The cost of glass packaging
Finishing metal packaging, glass packaging, is also a common form of current canned packaging. There is a serious crisis in the glass packaging industry in China.
During this four-year period, the output of the industry is basically in a low-speed growth state. The main reason is that the effective demand is insufficient and the supply structure does not meet the changes in market demand.
The main reason is excess production and increased competition. Constrained by cost factors and national environmental protection policies, industry enterprises in recent years have mainly shifted to areas where energy or raw materials are cheap, labor is cheap, and supporting industries are concentrated. The concentration of industrial production and the scale of production have all expanded.
However, in terms of product structure, glass companies have lower grades, lower technological content, and lower artistic content than ordinary products. They still use ordinary bottles and cans. Most companies perform cruelly in markets with low levels and serious surplus of products. competition. The foreign glass products continue to hit China and squeeze the domestic market.
As a high-energy-consuming industry, energy costs account for about 40% of total product costs. Changes in energy prices directly affect the overall economic efficiency of the industry. At present, due to the international situation, the price of petroleum continues to rise, and the cost of enterprises has increased. Although recycling of glass bottles can be reused, which is conducive to resource conservation and environmental protection, the above problems cannot be solved and will restrict their own development and also affect the canning industry. market development.
Soft-packaging shots when the shot
From the inside of the supermarket, soft canned packaging has already won the favor of some consumers. This type of packaging solves the “common problem†of glass bottles and tin cans - the status quo of “canned foodâ€, and is convenient for consumers to carry. transparency.
As early as the 90s of last century, China's edible fungus companies found that convenient soft packaging products were favored by consumers after researching the international market. Therefore, the edible mushroom companies in the main producing areas of mushrooms and asparagus in Fujian, Shandong, and Yunnan provinces. , Breaking through the packaging forms of traditional glass bottles and metal cans, developed flexible packaging products such as mushrooms and asparagus. After only a few years of development, domestic edible mushroom canned leading enterprises have occupied nearly 30% of the canned edible fungi market in Europe and Japan. This is a great solution to solve the problem of deep processing of agricultural products in China, and to increase the added value of the canned industry in China and create its own advantage brand.
For the production of canned edible fungus companies, they require soft packaging to be able to spray at high temperatures first, because mushroom foods need to be sterilized at high temperatures, so the soft packaging used needs to be able to withstand 120% of high temperature spray. It also requires strong barrier properties. At present, Japanese packaging products can make the canned food shelf life of more than one year, and domestic products of the same kind can only maintain the shelf life of the product in 8-9 months. Transparency is high, so that consumers can directly see the product, which stimulates the desire to buy. Solve the plastic bag's flexibility is not strong, easy to cause the problem of explosion bags.
Is our soft packaging plastic packaging manufacturing company inferior to people? There are media reports that high temperature flexible packaging technology does not exist in China. Some companies use multi-layer co-extrusion technology to co-extrude PE with barrier materials to produce products with the same functionality. This product can be used to determine the thickness of the barrier layer, and the product shelf life can reach 9-12. Months. For CPP and PE compounded plastic bags, it is possible to increase the flexibility of the product by adding elastomers. The domestic technology can also be satisfied. Some products can withstand high temperatures around 135 °C, fully able to meet the requirements of high temperature spray.
In short, the canning industry should "carry out both hard and soft", and neither can abandon the traditional "hard packaging" nor ignore "soft packaging."
