Generally, everyone knows the practicality and environmental protection of tin boxes, and then most people don’t have a deeper understanding of tin boxes. In fact, the products we see in tin boxes are generally made of tinplate. There are two types of tinplate cans: tinned iron cans and frosted iron cans. Tin-plated iron is also…
Tin boxes packaging products can be seen everywhere in life. Tin boxes are widely recognized as metal packaging containers. The process of tin boxes processing is roughly divided into six major steps. There may be other processing procedures depending on the product packaging process. Tin boxes are made of tinplate after printing. According to the…
Why tin boxes become a fashion trend in packaging? Tinplate packaging has better barrier properties, gas barrier properties, moisture resistance, shading properties, and fragrance retention than any other material. In addition, the seal is reliable and can better protect the product. The metal material has good printing performance, the pattern and trademark are bright and…
What do you think of food tin boxes? Recently, there have been hot searches on the Internet about food tin boxes, and everyone has raised questions about food tin boxes. Just as everyone cares about food safety, so does food tin boxes. First of all, tin boxes are not only used in the food packaging…
At present, the mainstream food tin box packaging material on the market is tinplate, but the difference in the production process makes the food tin box divided into two categories, one is the national standard cans and the other is the miscellaneous cans. Simply put, the national standard cans have a unified national production standard.…
Compared with other packaging materials, tin boxes have obvious advantages. 1. Good mechanical properties: Compared with other packaging containers, such as plastic, glass, and paper containers, tinplate cans have higher strength, good rigidity, and are not easy to break. Not only can it be used for small sales packaging, but also the main container for…
Tin boxes themselves have a feature that other packaging materials don’t have—the ability to be adsorbed by magnets. In this way, a magnetic separator can be used to separate the tin boxes from the waste by magnetic force. This feature can easily achieve recycling. The effect of 80% tin boxes in the middle. The invention…
Packaging materials for tinplate cans that meet environmental protection requirements Existing containers include iron cans, aluminum cans, paper and plastic containers. The recycling characteristics of these containers are different, but the recycling treatment of iron cans is better than other packaging materials. Based on the international environmental management standard ISO-14000, the implementation of tinplate cans…
Tin plating bath The main purpose This product is suitable for red copper and phosphor copper to prevent oxidation, improve rust resistance, and increase the appearance of copper parts. Two performance characteristics 1. It can turn the copper surface into a bright silver-white surface, with the beautiful effect of the surface color of cupronickel or…
Hardness test of tinplate In the past, the hardness test of tinplate mostly used the desktop surface Rockwell hardness tester, and the ordinary steel flat test anvil was used to test the HR30T hardness. Over the years, since the national standard GB/T2520-2000 for tinplate has adopted the internationally accepted HR30Tm hardness representation method, diamond anvils…
Ink drying process In tinplate printing production, the drying of ink is a complex physical and chemical reaction process. It is necessary to reasonably control the ink drying speed and master the physical and chemical mechanism of ink drying in order to effectively carry out fast printing operations and ensure product quality. Drying the ink…
Tinplate printing has special requirements for ink: Requirements for white ink The surface of the tinplate is silvery white (or yellow) with metallic luster. Before printing the color graphics, the surface needs to be painted or printed white. Due to the limitation of the ink coverage, the monochrome machine often needs to be printed twice,…
Principle of tinplate printing: Tinplate printing also uses the physical properties of water and ink to repel each other. With the help of printing pressure, the printing plate graphics and text are transferred to the tinplate via a blanket, which belongs to the principle of offset printing. Because tinplate has special physical and chemical properties…
Why choose tins for beverage and chemical? Tinplate cans can be used to fill juice, coffee, tea and sports drinks, and can also be filled with beverages such as cola, soda, and beer. The high degree of workability of tinplate cans makes the can types vary widely, whether tall, short, large, small, square, or round,…
Usage of tinplate Tinplate has a wide range of applications, from packaging materials for food and beverages to grease cans, chemical cans and other miscellaneous cans. The advantages and characteristics of tinplate provide good protection of the contents in terms of physical and chemical properties. Canned food Tinplate can ensure food hygiene, minimize the possibility…
Reduction effect of tin The tin on the inner wall of the tinplate interacts 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…
Opacity In addition to the deteriorating reaction of food, light can also cause changes in protein and amino acids. Vitamin C is more likely to interact with other food ingredients when exposed to light, resulting in a large amount of loss. According to research and analysis, the loss of vitamin C in clear glass bottled…
The origin of tinplate Cast iron originated in Bohemia (in today’s Czech Republic and Slovakia). The area has been rich in metal since ancient times, with advanced technology and know how to use water power to engage in machine manufacturing. Tinplate has been produced since the 14th century. After the First World War, the armies…
Development of Tinplate in packing industry According to the different requirements of the packaging industry, the thickness of tinplate material, the amount of tin plating, and the mechanical properties have different needs. Since its inception, tinplate has been developing in the direction of thinning. One is to use less tin, or even not to use…
What’s the advantage of tinplate? Tinplate packaging has a wide coverage in the packaging container industry due to its good airtightness, preservability, light resistance, robustness and unique metal decoration charm, and it is a universal packaging variety in the world. With the continuous enrichment of various CC materials, DR materials and chrome-plated iron of tinplate,…
