What metal is tinplate?

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.

Tinplate application

Because 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.

Advantages of Tinplate

1、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.
