Tinplate is a kind of ultra-thin cold-rolled low-carbon steel sheet, which is mainly used for tin-plated and TFS iron sheets used in the can industry. The main purpose of tin-plating is to avoid the corrosion of food to tinplate. Cans are light-tight, airtight, strong, non-deformable, shock-resistant, and fire-resistant, and have been widely used in common packaging materials such as meat sauce, fruit, tea, and coffee beverages.
Tinplate seat food-grade beverage packaging materials are widely used in food, chemical, industrial and other industries, such as food cans, beverage cans, grease tanks, grease tanks, chemical tanks, spray and other miscellaneous tanks. Its main feature is to support the protection of the contents in terms of physical and chemical properties. Therefore, the quality standard of tinplate is very important to the packaging and protection of the content, so a correct understanding of the quality and standard of tinplate is the basis of understanding of can making and one of the main keys to success or failure.
The development history of Tinplate ,Manufacturer of Tinplate
As early as the 14th century, Bohemia began to produce tinplate, which was mainly used to make tableware and water glasses. In 1800, the British manufactured tinplate cans for long-term preservation of food. In 1847, the Americans invented the canning machine. Since then, the demand for tinplate has continued to expand. At present, more than 1/3 of the tin produced in the world is used to make tinplate.
Bohemia (in today's Czech Republic and Slovakia). The area has been rich in advanced metal technology since ancient times, and knows how to use water power for machine manufacturing. Since the 14th century, tinplate has been produced. For a long period of time, here has been the main producing area of tinplate in the world. At that time, tinplate was mainly used to make tableware and drinking utensils.
Development In the 17th century, Britain, France, and Sweden all hoped to establish their own tinplate industry, but due to the need for large sums of money. So it hasn't been developed yet. It wasn't until 1811, when Brian Donkin and John Hall opened tin canned food, that tinplate manufacturing developed on a large scale. Today, the world produces about 250,000 tons of tin every year, more than one-third of which are used to make tinplate, most of which are used in the canned food industry.
1810: The world's first tinplate can was invented by the British and obtained a patent. At that time, a can making expert could make 60 empty cans a day. 1900: Invention of the electric welding machine. 1847: The United States invented the can making machine to replace labor. 1965: Aluminum easy-open ends are introduced for canning. 1973: Iron easy-open ends began to be used in canning. 1990: Canning technology was upgraded to over 1,000 cans per minute.
The origin of the name of tinplate Tinplate was called Tin Plate in the early days, and its official name should be tin plate. Because China's first batch of foreign iron was imported from Macau in the middle of the Qing Dynasty, Macau transliterated "Makou" at that time, so the Chinese generally call it "tinplate"..
1)Tinplate applicationBecause of its good sealing, preservation, lighting, solidity, and unique metal decoration charm,it determines that it has a wide range of faces in the packaging container industry and is a general packaging variety internationally.
With the continuous enrichment of various CC materials, DR materials, and chrome iron, the development of packaging products and technology has been promoted, and the Magou iron packaging is full of innovation everywhere.
The application of Macong Iron is very extensive. From packaging materials as food and beverages to oil tanks, chemical tanks, and other miscellaneous cans. The advantages and characteristics of the Macaor Iron provide the content of the content and chemistry in the physical and chemical properties. The Magou iron can can be used to fill the juice, coffee, tea and sports drinks, and can also fill cola, soda, beer and other beverages. The height of the Magou Iron can make the cans change a lot. Whether it is high, short, large, small, or square, or round, it can meet the diverse needs of today's beverage packaging and consumer hobbies.

3）Advantages of Tinplate1、Opaque
In addition to causing food deterioration reactions, light can also cause changes in proteins and amino acids. Vitamin C is more likely to interact with other food ingredients when exposed to light, resulting in a large loss. According to research and analysis, the loss of vitamin C in milk bottled in transparent glass is 14 times higher than that in dark bottled milk. The opacity of tinplate cans makes the preservation rate of vitamin C the highest.
2、good sealing
The barrier properties of packaging containers to air and other volatile gases are very important to the preservation of nutritional ingredients and sensory qualities. Comparing various fruit juice packaging containers proves that the oxygen transmission rate of the container directly affects the browning of the juice and the preservation of vitamin C; metal cans with low oxygen transmission rates, glass bottles and aluminum foil laminates, and cartons have a great impact on the preservation of vitamin C. It is better, and iron cans are the best.
3、tin reduction
The tin on the inner wall of the tinplate will interact with the oxygen remaining in the container during filling, reducing the chance of food ingredients being oxidized. The reduction effect of tin has a good preservation effect on the flavor and color of light-colored fruits and juices. Therefore, juice cans packed in unpainted iron cans have better nutritional preservation and less browning than juice cans packed in other packaging materials. The flavor quality is more acceptable and the shelf life is thus extended.
