White Coated Tinplate Sheets with Different Temper and Hardness for Various Applications
Influence of hardness:
Tinplate sheets of different hardness are suitable for different application scenarios. Harder tinplate sheets have better wear resistance and deformation resistance, and are suitable for occasions with high requirements for strength and durability, such as some industrial packaging that needs to withstand greater pressure or friction; while tinplate sheets with lower hardness have better ductility and processing performance, and are easy to perform stamping, bending and other forming processes, and are often used to manufacture consumer product packaging containers with more complex shapes.
White coating:
Ingredients and characteristics: White coatings are usually made of inorganic or organic materials, with good corrosion resistance, decorativeness and chemical stability. Inorganic white coatings such as ceramic coatings have the advantages of high temperature resistance, high hardness and wear resistance; organic white coatings such as polyester coatings and acrylic coatings have good flexibility, adhesion and weather resistance, which can effectively prevent rust and corrosion on the surface of tinplate sheets and provide beautiful appearance.
Functional advantages: White coatings not only add decorativeness to tinplate sheets, making them more beautiful in appearance, but also enhance their corrosion resistance and further extend their service life. In the field of food packaging, the white coating can also isolate food from tinplate, prevent acidic or alkaline substances in food from reacting with tinplate, and ensure food safety.
Applicable uses:
- Consumer product packaging: In terms of food packaging, it is suitable for all kinds of canned food, such as canned fruit, canned meat, canned fish, etc., which can effectively protect the quality of food and extend the shelf life; it can also be used for the packaging of dry goods such as candy, biscuits, tea, etc., providing good barrier properties to prevent products from getting damp and oxidized. In the field of beverage packaging, it can be used for some beverages with high packaging requirements, such as carbonated beverages, fruit juice drinks, etc., which can withstand a certain internal pressure and maintain the freshness and taste of the beverage. In addition, it is also widely used in the packaging of consumer goods such as cosmetics, medicines, and daily necessities, such as lipstick boxes, medicine packaging boxes, perfume bottles, etc., which can not only provide protection, but also enhance the appearance of the product. Grade.
- Industrial packaging: It can be used to package various industrial products, such as lubricants, coatings, glues and other chemical products to prevent product leakage and external contamination; in the packaging of electronic components, precision instruments and other products, it can play an anti-static and anti-electromagnetic interference role to protect the performance and quality of the product; it can also be used for the packaging of some small mechanical parts, hardware tools, etc. to prevent the product from collision, wear and corrosion during transportation and storage.
