The advantages and production process of high-quality tea tin cans

Tea is a traditional popular beverage in Britain. It is usually added with milk and sometimes sugar, but more often it is made with orange slices and jasmine to make Duke's black tea, black tea of ​​jasmine, black tea of ​​jam), black tea of ​​honey, etc. . On average, 8 out of every 10 people in the UK drink tea. The United Kingdom consumes nearly 200,000 tons of tea every year, accounting for 20% of the world's total tea trade, ranking first among European countries and calling it the "kingdom of tea drinking." Drinking tea is not only refreshing, but also a very good way to keep in good health. Therefore, tea is more and more popular among young people. Many families buy good tea and store it at home, but if it is not preserved, good tea will be wasted. In fact, the storage of tea is very simple, and there are many ways. Below we teach you the simplest one, storing it in tin cans. If you want to know how tea leaves are preserved, you must understand why tea leaves go bad, and what causes them to go bad?

   The main reason why tea leaves deteriorate is because they are not tightly sealed, which allows the tea leaves to absorb moisture and peculiar smells in the air, or the light shines on the tea leaves and the tea loses its original flavor. The more expensive the tea, the easier it will change its flavor. Storage in tin cans can solve this problem well. The tin cans are tightly packed, which can effectively block the contact between the tea leaves and the air, and have a good effect on preventing moisture, oxidation, light and peculiar smell. At the same time, the iron pot itself has no peculiar smell and will not affect the original fragrance of the tea. To ensure that the tea will not deteriorate, put the tea leaves in the tin can, close the lid, and place the tin can in a cool place. This will not only prevent the tin can from rusting, but also slow down the aging and deterioration of the tea. The tea stored in this way, no matter how long it is left, when it is taken out and re-infused, it will still be fragrant and refreshing.

   Tea tin cans are made of tin-plated iron boxes. The lid and the can body are produced separately and then assembled together. The advantages of this tea tin can are obvious, its airtightness is very good, can withstand higher internal pressure, and is very suitable for storing tea. At the same time, the high gas barrier, light-shielding and sealing properties of the tea tin can keep the quality of the tea in the tin stable.

The following article explains the advantages and production process of tea tin cans

　　1. Good airtightness; the body of the tea tin can is directly formed by the punching process, no leakage, and the leak detection process can be avoided.

　　2. The printing is beautiful; the body of the tea tin can has no joints, and the appearance is beautiful, and the can body can be continuously decorated and printed, and the effect is good.

　　3, to ensure product quality; tea tin cans do not need to be welded and sealed to avoid lead contamination of solder cans, and are resistant to high temperature sterilization, which can ensure product hygiene.

　　4. High production efficiency; the tea tin can has only three parts, and the can body manufacturing process is simple, which is great for simplifying the process and improving the production capacity.

　　5. Save raw materials; the body of the tea tin can is stretched and deformed when it is formed, and the wall thickness is thinner than that of the three-piece can.

Tea tin can production process

Each tea tin can is made of iron material-printing-cutting-stamping-assembly-packaging-step by step.

    (1) Tin-plated iron material: Generally, after confirming the order, the appropriate tin-plated iron material will be ordered according to the recent design layout drawing, including the type and size of the iron material. The quality of the tin-plated iron material can be assessed visually. , To see if there are scratch marks on the surface, whether the lines are uniform, whether there are rust spots, etc., the thickness can be measured with a micrometer, and the hardness can be felt by hand.

    (2) Tea tin cans and iron material printing: After entering the layout of the design documents, they will be printed in rows. Usually, tea tin cans samples are provided to the printing department for color tracking. What should be paid attention to during the printing process is to look at the printing tone. Whether the color keeps up with the color of the sample, whether the alignment is accurate, whether there are stains, whether there are scars, etc. The printing department generally responsible for these problems can control itself.

    (3) Cutting the iron material of tea tin can: the printed iron material of tea tin can can be cut and opened. When cutting the mattress, pay attention to whether the operator is cutting according to the knife edge line and whether the length is consistent and uniform. Whether workers scratch each other during unwinding, etc., the quality must be checked at the operating station.

    (4) Pressing the iron material of the tea tin can: pressing the iron sheet into shape on the punching machine, this is the main work of making the tea tin can, usually a tea tin can needs many processes to complete. The general process of a two-piece tea tin can with an independent lid is: lid: open material-flashing-winding. Bottom: Cutting-flashing-pre-coiling line-coiling line.

    Bottom-sealing process of independent lid tea tin cans, lid: opening-flashing-coiling. Can body: opening-pre-bending-cutting corners-forming-buckle bone-punching (bottom buckle)-back cover. The bottom process is: the material is usually lost during the stamping process. Pay attention to whether the work operation is standard, whether the surface of the product is scratched, whether there are batch seams in the coil, and whether the button is fastened. The usual practice is to arrange the production of large samples for confirmation before the production of large goods, and to produce according to the confirmed large samples, which can reduce a lot of trouble.

    (5) Packaging of finished tea tin cans: After the tea tin cans are produced, the packaging department is responsible for cleaning and assembling, putting them into plastic bags and packing. This link is the finishing touch of the product. The cleanliness of the product is very important. Therefore, it is necessary to do a good job of cleaning before packaging, and then package according to the packaging method. For products with many styles, the style number and box mark must be aligned and placed. put.
