Design of food tinplate packaging products

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 printing technology and processing technology, the application of tinplate packaging has become more and more extensive. 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. 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 according to the characteristics of processing and manufacturing of tinplate packaging and the characteristics of the printing and coating process. 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 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 tinplate 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 box of foreign wine Packaging, there are many deficiencies highlighted, such as when the wine bottle slipped, the lid and the can body can not prevent the bottle from sliding out, easily lead to higher breakage rate; 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-counterfeiting tin box for the liquor was designed and developed in cooperation with the customer. Liquor outer packaging, after the launch of the product, it was successful, and achieved sales of tens of millions of yuan. This was the first liquor security 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 in cartons or bares. In recent years, the use of blister packs and plastic cartons has grown. The grades of the packaging cannot be mentioned. Due to the heavy weight of ham, 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.

2, expand the application of existing products

For a company. Investment in equipment can generally not be increased without limit. Utilizing existing processing technology and equipment, or changing only part of raw materials and processing technology, 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.

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. The appearance is also obviously different. Consumers can tell from the printed pattern and shape of the box which is the tin box and which is the carton. For example, the shape of the iron box adopts rounded corners, while the paper box generally adopts folded right angles. Combining the shapes of paper boxes, wooden boxes and even ceramic packaging materials into the development and design of metal packaging together with the characteristics of sheet metal printing will open up yet another vast area for metal packaging products. As shown in Figure 1, the bottom of the tank and the tank body are made of the same iron sheet, and the can body is formed by a folding process, so that the four corners of the tank body are right angles. Can body mouth roll. The four corners of the can lid are also at right angles. The lid of the can lid is folded and pressed inwards. This merges the shape and processing features of the carton. The appearance of the can is like a carton, which changes the traditional image of the tin box. People feel refreshed. Also shown in Figure 2 is a hexagonal deep-jacketed sleeved can. The corner of the can body adopts a very small arc transition. Close to the standard obtuse angle, the bottom of the can is stretched and then crimped with the can body. The can lid is also divided into two parts. The lid body and can body have the same molding process. The outer edge of the lid is concave. The depth of the canal is the same as the inner curl of the lid body. After the lid body and lid are crimped, the lid is closed. The top is flush with the upper edge of the cover, and the top of the cover is flat. The height of the can body is the same as that of the cover. After the cover is closed, the integrity of the can is strong. This iron box combines the appearance characteristics of the plastic cake packaging box with an elegant color pattern, giving people a feeling of honor.

The iron box packaging transplant design method not only includes pattern transplant (such as wood grain, ceramic grain, etc.) and shape transplant, but also includes real transplantation of materials. For example, hinged plastic lid tea cans and coffee cans have appeared on the market. The cans and the bottom of the cans are made of tinplate. The use of tinplate is beautiful in printing, the hardness of the can body is good, the coating and the iron itself are non-toxic and odorless. Features, plastic cover lined with plastic ring, and then hinged with the can body, both to achieve the sealing function, but also can be opened multiple times, repeated use. This can type makes the perfect combination of the advantages of tinplate and plastic. The metal wine jar developed by our company is made of hard paper pull cover. Lowering the cost of the lid is also a good transplant product.

4, iron box packaging copying innovation

The innovation of packaging shapes can serve to evoke the youthful vitality of the product market, attract consumers' attention, and promote the sales of products. When using the profiling method for shape innovation. The first step is to determine the general characteristics of consumer groups such as entertainment, leisure, hobbies, and personality in accordance with the market positioning of product sales, and to select the shape objects to be imitated. The simplification and concentration of the shapes to be imitated must not only be "like." In addition, it is necessary to “behave like a god,” and then combine structural characteristics of the characteristics of tinplate processing, design patterns, and the shape of the contents, and at the same time consider ease of use and safety. Make sure that the model, content, and consumer's consumer psychology are coordinated. When selecting imitation objects, it should also be noted that it is in line with consumer trends and should not imitate the forms that others have already imitated. 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 there 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. ?

5. Functional innovation design method for tin box packaging

The functions of the packaging are various. The first thing to do is to adapt to the packaged product and to 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. It is called “temptation function”. Third, the package is best to have reusability. 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 products, which is called “assisting function”; other functions such as convenience functions, anti-counterfeit 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 tank is flush with the outer edge with respect to the outer surface. The depth of the depression is the same as the height of the bead. After the bottom of the tank is crimped with the can body, the outside of the tank bottom is flat and the can body of 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 into a series 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 inside the roll, 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 are engraved at the proper position of the can body, a rib is pressed under the reticle, and the distance from the lower reticle to the rib is 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, an ashtray with a new product is formed with the connection part of the bottom cover and the outer cover. Alcohol and tobacco are the best partners, and the wine bottle is completely packaged.
