The hottest metal packaging develops with each pas

  • Detail

The development of metal packaging is changing with each passing day

today, metal packaging seems to be two-piece cans, three piece cans and cylindrical barrels, most of which are cylindrical. With the rapid development of economy, metal packaging should also develop and innovate

for packaging users, three major factors are mainly considered: cost, environment and consumer demand. Among these three factors, the most obvious one is cost. Efforts to reduce material costs are important for all forms of packaging, and it is more important to reduce the cost of metal, because it accounts for the largest proportion of the total cost. Generally speaking, canning technology hardly limits the performance of packaging. Whether in the past or now, canning plants and steel plate suppliers are trying their best to produce higher quality products, process thinner and thinner metal packaging products, and are constantly exploring better materials to better shape the key parts of metal packaging and obtain better packaging performance. Therefore, if you want to get better development of metal packaging, you can only carry out design innovation, because it can get more and more innovative products, which makes people refreshing

at present, the can end of necked beverage cans on the market is relatively small, reducing materials and costs. Canned food all over the world also began to follow suit, reducing the edge

thin material is one of the ways to reduce costs and has a good development prospect. Since the mid-1970s, Europe has introduced the concept of thinness. When metal cans were made of 0.38mm thick materials, the weight of the cans was 40g. By 1993, the thickness of the materials used to make metal cans and the weight of the cans with only imperfect services were reduced to 0.28mm and 29g respectively. By the mid-1990s, 0.22mm steel was used, and the weight was reduced by 21%. At present, it is very common to use 0.16mm-0.2mm steel sheet to make cans. The weight of thin steel drink cans has been reduced. We are eager to show our solid system expertise to customers at JEC exhibition by 43%, and this change speed is very fast in the same period. At present, the thinness of metal packaging materials in China has also begun to develop rapidly. Now in the domestic metal packaging industry, there have been a large number of 200L steel barrels produced with 0.6mm steel plates. With the continuous updating of manufacturing technology and equipment, not only the thinness of materials has been achieved, but also the quality and production efficiency have been continuously improved

today, the representative of the innovative light tank body is the award-winning flexible square tank of British carris company, which was developed by the company in the Netherlands. The tank body has a reinforced flange, and the tank body is thinner, making the food tank more flexible when cooking at high temperature. Flexibility means that the pressure difference of the tank wall is smaller than that of the leading enterprise in China's graphene industry, so the tank body can be made of relatively thin (about 0.18mm) materials. This kind of packaging is a real light can, and its weight is 15% lighter than the current general metal


in recent years, the metal can that won the best prize in the European packaging competition is such a metal square can. It uses a packaging steel plate composed of an easy to open cover and an ordinary steel plate substrate with a thickness of 0.17mm, and its surface is coated with polymer paint. Manufacturers believe that tear off caps can also be used, and there is no need to exhaust when cooking cans. This kind of square can takes up 20% less space than the round packaging, and the axial bearing capacity is 2Kn, which is completely within the performance range of conventional metal cans. And the four sides of the can body can be printed with high-quality patterns

in terms of spray cans, light tinplate series two-piece cans have emerged in Europe. This kind of punching and stretching cans has the characteristics of thin can body and what kind of spray can opening, and it is seamless, which significantly reduces the proportion of metal used

in the packaging industry with increasing market demand, the design of metal cans is diverse, which requires packaging designers to constantly innovate to meet the different needs of consumers. A few years ago, the British carris company put a new decorative steel plate on the market. This material is composed of oxygen ordering experimental machine-made chromium plated steel plate and several layers of polymer coating film on its surface. At present, it has been applied in Europe. This polymer spray material has several layers of composite films, which can be metallized and can be printed with holographic trademarks. It has a protective layer, which is conducive to printing. Because the whole process is carried out on the plane, this series of decorative steel plates are not suitable for stretching cans, but they are ideal materials for decorative containers, easy to open covers, screwed off covers, crown covers, composite tank end covers and three piece cans. The surface of this material is bright and clean. Once it came out, it really touched the tinplate container market. Because the convex pattern on its surface is very beautiful, the holographic trademark really has a three-dimensional feeling. Making holographic trademarks on metal cans is a development trend. At present, holographic trademarks have been made on aluminum beer cans in Australia and other countries. Relevant experts believe that etching holographic trademarks directly on steel plates will be popular all over the world in the near future

freightt company in the UK is the most famous supplier of polymer coated steel, and its products have been sold on the market for several years. When the polymer film is cemented to the surface of the steel plate, the material must be melted and cooled sharply, so that a very large adhesive force can be generated between the steel plate and PP or PPT, so as to make good barrier, strong corrosion resistance and eye-catching packaging. At present, the most widely used are a kind of mixing jar and a kind of gel jar. There is also a new coating material, which directly extrudes the resin onto the steel plate. At present, it has been used in the production of food cans. At home and abroad, beverage cans and food cans are highly competitive fields, including tin cans, aluminum cans, pet and glass containers

we print metal cans, usually only the can body, but there is an obvious development trend at present, that is, color printing is also carried out at the end of the can. Now there is a necking can on the market, which uses a striking black easy to open cover, so that the design style can be extended more widely. On the other hand, the development trend is that printing metal cans is not the only market for food and beverage cans. At present, it has also been fully expanded in the printing of other cans and barrels, such as decorative paint series metal cans, metal barrels and cans for building materials, etc. Now, the most considered by businesses is the packaging container of such a commodity. Even if consumers spend a little more money, they can buy a packaging that can make the product unique on the shelf. For this point, the decoration of metal cans is undoubtedly a fashion today

there are also some new technological achievements in metal cans, which have greatly expanded the uses and functions of metal cans. For example, a new ink can change color with the change of temperature. In the past, this kind of ink was only used on the external label of cans, but now the thermometer can be directly printed on metal cans. There is also a touch sensitive ink, which can react with the surface below and make the image show physical changes. For example, it can be used to highlight changes in internal food

providing convenience to consumers is a matter of course for commodity packaging, and the metal packaging industry is no exception. With the progress of technology, it is very easy to open the lid, and precision tools and materials have developed greatly, so metal cans must have convenient ways to open the lid. You should know that this is a classic constraint, because only consumers are the most discriminating group
