Driven by the market, the design innovation of metal packaging can body

metal packaging has developed to today, which seems to be two-piece cans, three piece cans and cylindrical barrels. Most of them are cylindrical, and the shape has not changed much. However, if the packaging wants to develop and innovate, it cannot remain unchanged, which does not meet the requirements of the development of the times. So metal packaging still needs to be developed, so how to develop it? That is design innovation. In this regard, foreign developed countries have come ahead of us. Nike Oren, a British packaging expert, said: "when all manufacturers are manufacturing products of comparable quality and price, design and innovation are the basis for metal packaging to survive and maintain its advantages"

bright metal texture is the inherent essence of steel plate, and the new century has added competitive advantages to it. Because metal products are "cool" in appearance, they are attractive in supermarkets all over the world. However, no matter how eye-catching the goods are, for packaging users, the main consideration is three factors: 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, in order to achieve better development of metal packaging, only design innovation can be carried out, because it can get more and more innovative products, so as to make people refreshing

at present, the can end of necked beverage cans in the market is relatively small, which is equivalent to reducing materials and costs. There is an obvious relationship between materials and forming technology. Now, canned food all over the world has begun to follow suit, reducing the edge

the development of thin materials has a strong momentum in recent years, and has a good development prospect. Since the mid-1970s, Europe has introduced the concept of thinness, which has reduced the weight of thin steel sheet beverage cans by 43%, and this change rate has accelerated in the 1990s. At present, the thinness of metal packaging materials in China has also begun to develop rapidly. Now there is no conflict in the production of domestic metal packaging industry, and a large number of 200 liter steel barrels produced with 0.6mm steel plate have appeared, This is a great progress

this development process can be traced back to 1973. At that time, the metal can made of 0.38mm thick material weighed 40g. By 1993, the material thickness and weight of the metal can 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. With the continuous updating of manufacturing technology and equipment, not only the thinness of materials has been realized, but also the quality and production efficiency have been improved

at present, the representative of the innovative light tank body is the award-winning product "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, so the tank body can be made of relatively thin material (about 0.18mm). This kind of packaging is a real light can, and its weight is 15% lighter than the current general metal cans

in the European packaging competition in recent years, the metal can that won the best prize is such a kind of 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 the opening of traditional spray cans, and is seamless, which significantly reduces the proportion of metal used

in the packaging industry with increasing market demand, there are various designs of metal cans. How to successfully attract customers? At present, many people in the industry consider that we have used the same coating material or can cover form for a long time, which is not suitable for today's market requirements for a long time. Consumers are looking for new incentives, and we also need to constantly seek alternative products. A few years ago, British carris company put a new kind of decorative steel plate on the market. This material is composed of chromium oxide plated steel plate and several layers of polymer coating film on its surface. On the other hand, it can be used as one of the reference data of operating speed, tension conditioning and film running wear of active packaging machinery. 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, screw off covers, crown covers, composite tank end covers and three piece cans. The surface of this material is bright and clean. Once it was born, it really moved 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, a seasoning jar and a gel jar are most widely used. 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. Therefore, to understand the situation of the packaging industry, you can find everything in this field. Now, consumers have more and more requirements for packaging. They want to know more about packaging. Therefore, printing technology is particularly important. The printing of tinplate in China has remained at the level before the 1980s. Until recent years, we have six color printing system and quick drying ink, which can print quite excellent things

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, what businessmen consider most is the packaging container of a kind of commodity that adjusts the passive frame to the horizontal position through the line adjustment device on the boom. 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 an absolute 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 kind of 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 it can print thermometers directly 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 not willing to lag behind in this regard. Not long ago, the author saw a kind of lunch meat can in the supermarket. Its packaging is a cylindrical three piece can with exquisite printing, but it is placed in the special price area, and the price is twice as low as that of similar products. I don't understand it. I think it's probably not of good quality. I bought two cans and went home to study them. Only then did I find that the can could not be opened because it had neither an easy to open lid nor tear marks on the can body. When I was helpless, I used the oldest method to cut a circle along the edge of the pot with a kitchen knife, and the cover was cut off. However, due to the uneven cutting edge, the whole piece of lunch meat was stuck on the edge and couldn't be poured out until I dug out all the meat, which had become shapeless. Only now do I know why this kind of lunch meat is not selling well. In Europe, pet food cans are equipped with easy open lids, and food cans without easy open lids have disappeared

with the progress of technology, it is very easy to open the lid, and there is a great development in precision tools and materials, so metal cans must pass the high-temperature treatment flawlessly, and they must have convenient ways to open the lid. There have been successful cases to implement the deposit system. We know that this is a classic constraint, because only consumers are the most discriminating group. It is said that in today's thin material, the manufacturing tolerance of the easy to open cover is equal to that of launching a rocket to the moon, and it can achieve high precision at an amazing manufacturing speed

the development of metal cans lies in innovation. Creative design can not only reduce costs, but also increase the competitiveness of goods, but also meet the growing needs of the market and consumers
