As people's consumption levels continue to increase, people's requirements for food packaging are also increasing. Food packaging materials are varied. In addition to metals, there are various wood, plastic, paper, and bamboo materials. In metal packaging, it is mainly tinplate packaging. Due to the continuous improvement and improvement of tinplate can printing technology and processing technology, tinplate packaging has become more and more widely used. The market share has rapidly increased and shows a trend of development year after year. The continuous development of tinplate packaging has become the top priority for packaging manufacturers and packaging design workers.1, expand the scope of application of existing products
For a company. Investment in equipment can generally not be increased without limit. Utilizing existing processing technologies and equipment, or changing only part of raw materials and processing techniques, and expanding the scope of application of existing products is a road to developing new products with low investment and quick results. Welded three-piece cans have been used only for the packaging of rice porridge, fruit and vegetable beverages, and slightly acidic beverages. The shape is also limited to several types of cans, such as a constricted neck and a three-necked neck. First, the equipment was slightly modified, or a small amount of equipment was added. From the height, can diameter to the number of necking, etc., major changes were made, and many types of cans were expanded, successfully applied to the packaging of seeds, cigarettes, candy and other foods. The research and improvement of the raw materials and processing technologies of the inner coating and the weld repair coating have rapidly expanded the scope of application of the original three-piece can product and has been widely used in chicken powder, chili sauce, soybean meal, canned fish, condensed milk, In industries such as strong acid beverages and oils, the potential of existing equipment has been fully utilized and the market adaptability of products has been greatly improved.
The organic combination of packaging products and advertising products. It is also a big space for the development of packaging products. In the past, the main role of packaging products was packaging, which was a matter of course, and the advertising role of packaging products was at best assistive. The development of ad barrels such as "He Zhi Lang" has changed this mentality. The advertising barrel can be used as a food for packaging jelly, candy, dried fruits, etc., and can also be used as a shelf for the purchase of supermarkets, shopping malls, and as a product advertisement for a manufacturer. It also facilitates businesses. The same package has three functions: "Packaging, Advertising, and Shelf". It can be said to be a classic application for the development of packaging products.2. Develop new industries based on food characteristics
Many food industries have not adopted iron box packaging because of the influence of thinking and traditional habits. This is a vacuum zone for product development and has a lot of room for development. The development of new industry packaging is most likely to play a role of “leading the market and leading the market”. To develop a new industry, we must first break the ideological confinement, carefully analyze the product's performance and market sales orientation, and figure out why we did not use iron box packaging before, and then proceed with specific characteristics based on the characteristics of tinplate packaging processing and printing processes. Product design and development. Before 1997, the packaging of domestic liquor was generally a carton, and there was no tinplate box. There was a small amount of tin in foreign wines, but the shape was simple and the structure was simple. Our company has carefully analyzed the market information of liquor sales and the defects in the packaging. We believe that the carton has poor anti-counterfeiting performance, low strength, poor anti-collision performance, and poor water and moisture resistance. On the other hand, the packaging products use a single raw material for a long period of time. Consumers have some "visual fatigue." At the same time, a large number of wineries in order to improve product quality, attract consumers' attention. Continuously introduce new, more and more high-grade imported cardboard. For anti-counterfeiting, all sorts of methods were tried, but the results were not ideal. All of this leads to higher and higher packaging costs for wine. Due to the "novelty" there is no qualitative improvement. The increase in packaging costs did not play a role in promoting sales. The use of non-paper raw materials to develop new packaging for wine has become an urgent need for the market, and tin can packaging just overcomes these deficiencies, and has the characteristics of beautiful printing, convenient mechanical processing, and low middle price, but if you imitate the iron of foreign wine Box packaging, there are many deficiencies highlighted, such as when the wine tank slipped, the lid and can body can not prevent the wine bottle sliding out, easily lead to increased breakage; no anti-counterfeiting features and so on. After analyzing these characteristics, the company proposed combining the features of the easy-open lid of the ordinary iron box and the three-piece can to realize the idea of a multi-functional packaging box. The first-generation EC anti-counterfeit iron box for white liquor was designed and developed in cooperation with the customer. Liquor packaging, after the launch of the product, it was successful in one fell swoop, and achieved sales of several tens of millions of yuan. This was the first liquor anti-counterfeit tin box in Chinese history, which led to a revolution in white wine packaging. Most white wineries have adopted iron box packaging. Later, our company developed a series of white liquor packaging and became another high-quality product of our company. Another example is the local specialty of Zhejiang, ham, which has been used for many years as a carton or bare pack. In recent years, the use of blister packs and plastic cartons has grown. The grades of the packaging cannot be mentioned. Due to the large ham weight, the packaging requires strong strength. , Stiffness, while a large part of the ham is sold as a gift of the positioning, the development of high-end gifts with metal ham cans is the market's urgent requirements. My company immediately developed a window gift metal box for ham and was favored by the ham market. A number of ham manufacturers quickly adopted this package and put it into the market. This is the first in China and has received good economic benefits.3, iron box packaging transplantation innovation
There is a wide variety of packaging materials. Each material has its own characteristics and traditional habits. Each packaging industry and most packaging manufacturers are innovating. As a designer and developer of metal packaging products, it is a practical and feasible method to absorb the heads of public homes, improve the printing and processing characteristics of iron sheet, and enrich and develop the structural shape of iron boxes. In the past, the forming process and procedure of two kinds of material boxes, iron and paper, were completely different. Appearance is also obviously different, consumers can distinguish from the printed pattern and shape of the box. At the same time, imitate horizon should be relaxed. There are many shapes that can be imitated, such as familiar cute animals, daily necessities, and shapes that have already been accepted for everyone. Currently on the market are: small pandas, dolls, cars, televisions, shoes, mailboxes, heart-shaped, star-shaped, egg-shaped, drum-shaped, suitcase-shaped, bag-shaped, book-shaped, basket-shaped and so on. Profiling product packaging. Its market positioning is generally for children, young people and other consumer groups. By replicating innovative new products, it is easy for the market to accept.4. Functional innovation design method for tin box packaging
The function of the packaging is various, and it must first be adapted to the packaged product and meet the requirements of the product during the transportation, storage, sales, use, and recycling of the product. This is the first function of the package, the "basic function"; the second is to display, on the one hand, the function of displaying the basic information of the content. On the other hand, it must have its own personality and style. It should have the function of attracting consumers and attracting consumers' attention, which is called “temptation function”. Third, the packaging should be reusable. In other words, the “secondary use” of packaging materials, which stimulates consumers’ desire to purchase from the packaging aspect, has the function of promoting the sales of the product, which is called the “assisting function”; other functions such as convenience functions, anti-counterfeiting functions, etc. . In the packaging design. Giving full play to the function of packaging is the development trend of packaging design. As shown in FIG. 3, the push-type food cans are rectangular in shape. The bottom of the can is flush with the outer edge relative to the outer surface. The depth of the punching is the same as the curling height. After the can bottom is crimped with the can body, the outside of the can bottom is flat and the can body is rolled out. The structure of the tank lid is more complicated. The lid edge is rolled inside. After one end of the lid is cut off and the lid is closed, the inner lid is folded and pressed tightly. The circular transition is made with the lid body and several positioning points are punched on the lid surface. After the lid is closed, the hand is pushed. Type function. The structure is simple and novel, and is suitable for the packaging of children's food. After the children finish eating the contents, the packaging can be used as a stationery box, which is in line with the purchasing psychology of children and children's parents. As shown in FIG. 4 , the car-type chocolate can is a simplified car with an overall shape. The can body and the can lid are formed by stamping, and the can body is necked and then rolled up. The can lid is a roof shape, and the windows and wheels are represented by a pattern, and the lid edge is rolled inward. The can body and lid are hinged. The hinges of the can body are concave and the hinges of the can lid extend. They are connected at two black tires. After closing, the exterior looks flat and resembles a car shape. The size of the tank is the same as that of a large stationery box. In this way, after the chocolate is eaten, the package can be used not only as a child's toy but also as a children's stationery box, which is in line with the purchasing psychology of children aged 2 to 10 and parents of children.
Liquor anti-counterfeiting packaging cans series. It is a successful example of a functional innovation approach to the development of new packaging. While implementing anti-counterfeiting features. Continuously develop new structures, new shapes, realize new combinations of functions and functions of packaging, and continuously introduce new products, forming a serialization of white wine packaging. The wine jar shown in Figure 5 consists of a can body, a tank bottom, an inner lid and an outer lid. A small hole of about 50mm is opened in the middle of the outer cover, the edge of the small hole is rolled inside, and the outer cover edge is rolled out. The inner lid is stamped and formed. The convexity of the inner cover is flush with the top surface of the outer cover. Like the bottom of the tank, the inner lid and the can body are rolled and formed. Two lines were engraved at the proper position of the can body, and a rib was pressed under the reticle. The distance from the lower reticle to the rib was equal to the depth of the inner cover of the outer cover. After opening, anti-counterfeiting function is realized because the can body is cut off. After the can body is disconnected, the bottom cover connection part and the outer cover form an ashtray with a new product, tobacco and alcohol are the best partners, and the wine cans become an ashtray after the mission of completing the packaging, which is both economical and practical, and effectively achieve.
