What is the Commercial Value of Special-shaped Tinplate Cans?

At present, products in tinplate cans are very popular in the market, such as milk powder, beverages, gifts, snacks, tea, coffee, candles, candies and so on. Why are these products keen on tin packaging? What commercial value can tin packaging bring to your store?

First of all, we need to know that the shapes of tinplate cans are all sorts of strange, round cans, spherical cans, square cans, special-shaped cans, and special-shaped cans have lip-shaped, heart-shaped, car-shaped, belly-shaped, oval, animal-shaped and so on. Many consumers may think that common cans, such as round cans and square cans, are too ordinary and not attractive.

Therefore, they are often attracted by some new things, and the special-shaped cans are especially in line with the consumer’s aesthetic cans. The more special things, the more they want to find out.

In the cosmetics industry, heart-shaped, lip-shaped, and flower-shaped cosmetic boxes will arouse the hearts of girls. Can the kawaii appearance, exquisite patterns, and bright colors look bad in the eyes of consumers? Now this society is chasing fashion beauty. As long as the shape and structure can keep up with the trend of the times, you are not afraid that your products will not be sold!

In the tea industry, tea cans are generally of high quality, and it feels more worthy to send to relatives and friends. Tea culture is a traditional culture that has been passed down in our ancient times. It has a long history and even foreigners love to drink Chinese tea. There are many types of tea, and there are also many tea packaging cans. The ones we often come into contact with may be square, round, and rare pot-bellied cans, or other special-shaped cans. To be honest, the pot-bellied pot is a practical and exquisite tea pot I have seen. It is not cumbersome at all, looks comfortable, and feels great to the touch. Its appearance can be embossed with patterns, especially retro and not fashionable. You can check it out online to see if what I said is true or false.

In the food industry, the food industry does not require much of the shape of iron cans, but the quality requirements such as the degree of sealing and hardness of the iron cans are somewhat high. The iron can itself is very rigid and extensible, and can be made into iron cans of various shapes. There is no doubt about the tightness of the iron cans. The crimping machine and manual edge grinding make the iron cans have no gaps.

All in all, for different products, use different tin can designs to show your sales philosophy and let your products enjoy the hearts of the people.

How Can Tinplate Can Be Designed to Attract Customers

The type, size and sealing method of metal cans are restricted by can making equipment. At present, many metal containers, especially cans for canned food and materials, have been standardized in size, structure and form. The standardization and standardization of metal containers have also promoted the standardization and standardization of related manufacturing facilities, thereby making the molding and manufacturing of containers relatively simple and easy. Therefore, the structural design of the metal cans is essentially just selecting the cans type, material and decorating design on the outer surface of the cans according to the user’s requirements.

The determination of the can’s structure of all the cans must take into account factors such as packaging requirements and manufacturing costs.

(1)Factors affecting cost, round cans compared with other special-shaped cans, round cans are not only relatively easy to manufacture, but also use less materials. In the capacity phase。

Under the same conditions, a container with a regular hexahedron uses 40% more material than a round cans, but from the perspective of the round lid’s cutting rate, the utilization rate during optimal discharge can only reach about 80%. Therefore, when designing metal cans, from the perspective of saving materials and reducing costs, round cans should be used as much as possible. The special-shaped cans has a unique shape and its cost is more than twice that of the cylindrical cans. It is only used when necessary.

In addition, the production efficiency of the two-piece can production line is higher than that of the three-piece can, but the investment in equipment is much larger than that of the three-piece can. These factors must be taken into account when determining the economic structure of the metal can.

(2)When selecting the can shape, the packaging requirements of the contents should be met,the metal cans should be determined according to the characteristics of the contents and the packaging requirements.

Structure, shape, opening method, sealing form, bottom and cover and side seam structure, etc. Common opening methods are cut-open, roll-open, pull-open, etc., and the sealing forms are air-tight and non-air-tight. Food cans and beverage cans generally require good sealing, and the sealing method can choose a double seaming structure; the opening method: generally the former using a cut-open type, the latter adopts a pull-open type, and the lunch meat is to ensure that the shape of the meat is complete when the can is open. , Mostly take the side unwrapped square can as the packaging container. An important feature of non-food cans is that they can be opened and resealed multiple times.Among them, art cans mainly used for daily necessities and cosmetic packaging, attaching great importance to artistic styling and decoration design; The metal cans mainly used for paints, oils and small packages of some chemical products, pay attention to the performance of the use rather than pay attention to decoration, which requires convenient transportation and a certain strength. The universal can used for tea and candy packaging can be sealed with a lid. The joint between the can body and the can lid does not require a double seaming. In addition, whether to install locking rings on the lid and bottom of the metal cans, whether rolling ring ribs are needed around the can body depends on the specific requirements of the production process and transportation environment. When the standard roll seal structure is selected, the size design and calculation of the roll seal structure can no longer be performed.

In short, when determining the structure of metal cans, factors such as the characteristics of packaging, packaging requirements and cost must be considered.

How Are Tin Cans Made

Tinplate can, as the name suggests, is a packaging can made of tinplate. Tinplate is the tin on the surface of iron to protect it. Compared with other materials, cans are more widely used, such as tea cans, biscuit cans, gift cans, wine cans and so on. In addition to the diversity of printing on the surface of the can, and the good gloss, it is more beautiful and beautiful. The reason why people like to use tin can packaging is that the compatibility strength of tin can is good and it is suitable for preservation.

Tinned tinplate is the material of tinplate. Because of its excellent metal toughness, tinplate can be easily made into different shapes, which makes the metal packaging container full of variety. It can not only increase the sales volume of packaging products, but also have artistic and recyclable green packaging characteristics. In the future development space, it is still open and incomparable. The following Makou iron can factory Bo new can for you to explain the manufacturing process of iron cans, I believe you can broaden your horizons!

1.Before making tins, we need to select materials. Tinplate types can be divided into: bright iron, silver iron and smooth iron. Smooth iron is widely used in can making. The above several kinds of iron materials have their own characteristics and can produce different effects. Therefore, different materials should be selected according to the characteristics of the products in the can making production.

2.After determining the can making material, it is necessary to determine the shape and making process of the can. At present, the main shapes of can are square, rectangle, circle and so on. The shape of foreign cans tends to be special-shaped, such as chezai can, heart-shaped can, plum shaped can, lip shaped can and so on. In the production process. Embossing, embossing, hollowing out and printing are the conventional production processes, but the effect of each process is obviously different, so it needs to be determined according to the customer and product positioning factors.

3.Printing oil selection. The iron material after printing needs oil treatment. This process can directly affect the visual and tactile effects of consumers on the cans. Different oils bring different visual and tactile feelings. The purpose of oiling is to attract consumers and improve product sales. At present, the more common oil is light oil (transparent oil), followed by dumb oil. There are explosion oil, pearl oil, wrinkle oil, rubber oil, etc.

With the continuous improvement of can making technology and the continuous updating of equipment, the automation level of tin can packaging production is higher and higher, the process is more sophisticated and the finished products are more exquisite. And the cost will get lower and lower. Can packaging is bound to become the packaging products chosen by manufacturers in various fields!
