Making process of cookie tin box

When we buy holiday gift cookies, what we have to look at is the appearance of the cookie tin box. When buying holiday gift cookies, we should pay more attention to the appearance. What we buy is not only the taste, but also the beautiful ones. Packaging can be said to be the cookie sales driven by the packaging box. Many friends are also attracted by the creative, colorful, and odd-shaped cookie tins when shopping, which arouses the desire to buy. Shopping for gift cookies is a very happy thing. Smelling the scent in the cookie tin box will arouse your appetite. Studies have shown that sweet foods can bring people happiness and satisfaction, which is related to the stimulation of hormone secretion during the digestion process of cookie food. High-quality cookies need to be stored well to prevent the cookies from spoiling. Putting them in a well-sealed tin container can prevent the cookies from oxidative deterioration. So how is a hot-selling high-quality cookie tin box made? This article is shared by a professional tin box manufacturer:

1. Selection of cookie tin box type

   At present, in addition to the regular square, round, and heart-shaped cookie tin boxes, there will also be more and more complex special-shaped can structures. In order to facilitate production, it is necessary to make strict discussions on the shape and size of the cookie tin box. For example, the thickness of the cookie tin box is thin, and the designed stretch height should not be too high, so as not to "break" the tin plate during punching; at the rotating part, the R angle should not be too small; Many manufacturers hope to use tin boxes to replace certain plastic packaging or paper packaging on the market. However, due to the physical properties of tin-plated iron and canning technology, certain modifications to the box shape are required or they cannot be manufactured. If the delivery time is urgent, you can find the original suitable box-shaped mold from the tin box manufacturer according to the size of the cookie tin box to produce, saving the time and cost of making the mold.

2. Graphic design of cookie tin box

  Good design can better perform or strengthen the advantages of cookie tin box packaging and promote consumer purchase. The shelf visual effect of cookie tin box, in addition to the metallic texture brought by tinplate, lies more in the visual impact brought by the exquisite printed patterns. Therefore, making the graphic design of the cookie tin box will be the top priority of the entire cookie tin box development. At present, most customers choose professional design companies for design. At the same time, in recent years, our company has established its own design team to update the tin box design better and faster.

3. Printing process of cookie tin box

   The raw material for the production of cookie tin boxes is tin-plated iron. The first step in making tin boxes is how to print patterns on the tin-plated iron. Nowadays, most tin boxes are printed with exquisite patterns, making the tin boxes not only play a role in food preservation, but also a decorative appearance. The tin-plated iron printing process is completed on the iron printing production line. The iron printing production line is generally composed of a feeding device, an offset printing unit, a coating unit, a drying room, and a film collecting device. Tin-plated iron printing is transferred to the surface of the iron sheet through the principle of water and ink balance under the action of the appropriate printing pressure by the cylinder.

1) Surface treatment effect of cookie tin box

After the tin-plated iron is printed, a layer of surface protection oil is needed to increase the scratch resistance of the printed iron (tin-plated iron after printing), and at the same time increase a certain degree of hardness, so that the printed surface coating has a certain flexibility and Corrosion resistance. Different surface protection oils will give the iron box a different look and feel.

The following are commonly used protective oils:

Varnish: Good color retention performance, can improve the vividness of printed colors and make the tin box higher gloss, in line with the traditional aesthetic habits of consumers.

Dumb oil: make the surface of the printed iron matte, have a paper texture, and have an elegant decorative effect.

Over-light stamping matte: You can also apply a layer of varnish on the stamping iron, partially stamping matte oil, the difference in gloss and touch, and highlight the key information through contrast.

Explosive oil: the surface of the printed iron has irregular explosive lines, which are crystal-like transparent scales. The reflection of light makes the exquisite printed patterns rich in three-dimensionality, a feeling of rustling, and sometimes a color-changing effect, which is very ornamental Sex.

Pearlescent oil: Let the surface of the iron box have a layer of luster like small water droplets, set off the brilliance and brightness of the printed graphics.

Orange peel oil: It will give the printed iron a corresponding touch, a bit like the lines on the surface of orange peel.

Rubber oil: With this oil, it feels soft to the touch, and there is no iron feeling at all.

4, cookie tin box stamping processing

  Tinned iron has good ductility and can be stamped into boxes of various shapes. Stamping is a kind of metal processing technology, which is widely used in the processing of plastics and metals. It is the process of forming iron materials in an instant by applying pressure. Process the tin-plated iron material into the required shape and semi-finished products. And stamping is also divided into cold stamping and hot stamping: cold stamping is metal processing at room temperature, generally suitable for iron materials with a thickness of less than 4mm, and has the advantages of high productivity, high precision and strong stability. The production process of cookie tin box under general conditions is: iron material-cutting-stamping-assembly-packaging. The stamping process is an important step in the formation of cookie tin boxes. The general process of cookie tin box stamping can be divided into: opening-pre-bending-corner cutting-forming-button bone-stamping-back cover.

5, cookie tin box carving (excited convex) craft

The good carving on the surface of the cookie tin box can enhance the quality and beauty of the box. Graphic design and engraving: The reason why metal packaging is more and more popular with consumers is that colorful graphic printing adds to the beauty of the iron box, coupled with the right engraving to make it more three-dimensional, and make cookies The visual effect of the iron box shelf. Therefore, how to choose a suitable and exquisite graphic pattern according to the characteristics of cookies or food companies requires rigorous design and discussion. As for carving, it is divided into flat carving and relief carving. Flat carving means that the protruding part is flat, which is two-dimensional. Generally, flat carving is done on the company's LOGO or product, and double-layer flat carving can be done according to the design effect. The reliefs have irregular protrusion heights, which are three-dimensional, making the flat patterns more three-dimensional.

6, common problems of cookie tin box craft

1) Stretching and discoloration of cookie tin box

Whitening is a common printing problem in stretched tin boxes, and its occurrence is mainly related to the size of the R angle. When the stretched height of the tin box is greater than 2/3 of the R angle, whitening will occur with great probability (r is 1 ), for example, for the corner of R3.5, the safe stretch height is 3.5*2*2/3 which is 4.67mm. Exceeding this height (r is 1), there will be a high probability of whitening and other phenomena. The same with special-shaped cans;

Calculation formula (rN-1)+R*2*2/3

In addition, whether the whitening is obvious is also related to the printing color. The darker the color, the more obvious the whitening appears, and the lighter the color, the less obvious the whitening situation. The hardness of tin-plated iron material will affect the stretching ability of the can. The softer the iron material, the easier it is to stretch because the box is stamped out by the die. The greater the hardness of the iron material, the easier it is to wrinkle in the stretched area. There will be a certain buffer effect.

2) Chromatic aberration appears in the cookie tin box

   Provide accurate design drafts or color value references when making cookie tin boxes; when customizing tin boxes with tin box manufacturers, you can provide an accurate color value or detailed samples for the printing factory’s reference, and express it clearly The color effect you want, so as to make the printing factory closer to the expected printing effect.

   .In the printing process, the speed of the printing press will affect the color depth of the iron sheet printing. During printing, the speed of the vehicle is unstable and the pressure is different, resulting in uneven ink coating on the iron sheet, and the color looks naturally different. For example, the higher speed of the generally imported offset printing press is 16,000 sheets/hour, and the speed of the domestic offset printing machine is 8,000 sheets/hour. Regardless of the advanced printing machine, the vehicle speed should be stabilized at about 70% of the higher vehicle speed, and the stability of the vehicle speed should be maintained, which can reduce the color difference.

  After surface treatments such as coating, varnishing, matting, oiling, and printing, tin-plated iron sheets will have different degrees of hue changes according to different production environments and different drying times. These changes include physical changes and chemical changes. These changing factors must be taken into consideration when the iron sheet is printed, so as to produce a color closer to the sample draft.

7, cookie tin box packaging, inspection and delivery

Packaging is the last process in the production of cookie tin boxes. After the finished product is cleaned and put into the tape, it will be boxed and stored according to the customer's packaging requirements. In the packaging process, two links are very important. One is cleaning. The oil stains and fingerprints on the surface of the box should be cleaned during stamping. The second is inspection. During the packaging process, there are defective products that do not meet the requirements and need to be picked out. Before delivery, the relevant personnel of the iron box manufacturer need to check, and the product can be shipped only after it is qualified. Regarding transportation, you can choose special vehicle transportation or logistics transportation, which is determined according to the quantity.

   The production of cookie tins is more complicated than that of cookie cartons; its price is higher than that of paper boxes. Customers who have made cookie tins will know that cookie tin manufacturers are customizing cookies of any shape In the case of tin boxes, the more expensive tin boxes are ordered, the cheaper the price. On the contrary, the smaller the order quantity, the more expensive the unit price. A cookie tin box, no matter how many, even if only one is made, the production process (printing, cutting, stamping, packaging) is the same. For the time being, we will not talk about printing and iron materials, just talk about cookie tin box stamping A three-piece can with a common row shape (such as a circle) can be finally formed after at least dozens of processes. The cookie tin box mold requires at least nine sets, and the entire production line is down. It takes only half a day for workers to replace the tin box molds. Adding a line of production workers will increase the production cost. The main production cost is labor cost.

Conclusion: The production of cookie tin box is divided into lid and box body, the main production steps:

1) Lid: cutting, waxing, stamping, flashing, pre-curling, crimping;

2) Box body: cutting, cutting corners, bending, buckle, pre-curling, and curling;

3) Box bottom: cutting, waxing, bending, punching, flashing, pre-curling;

4) Finished product: box body and bottom, punching the box, forming packaging;
