What is tinplate and why is it a popular packaging material?
Tinplate is a common metal packaging material composed of elements such as iron, tin and lead. Its surface is plated with a thin layer of tin to protect ironwork from corrosion and oxidation. Tinplate is usually used to make food packaging containers such as cans, cans, candy boxes, and biscuit boxes. This article will detail the features and advantages of tinplate and why it has become a popular packaging material.
First of all, what are the characteristics of tinplate? The main components of tinplate are iron and tin, and the content of tin is generally between 1% and 7%. The addition of tin makes the surface of tinplate smoother and better in corrosion resistance. In addition, tinplate often adds some other elements, such as lead and aluminum, to improve its processing performance and mechanical strength. The surface of tinplate is plated with a thin layer of tin to protect iron products from corrosion and oxidation, and it can also play a decorative role.
So why has tinplate become a popular packaging material? The main reason is that tinplate has the following advantages:
1、 tinplate has excellent corrosion resistance. Food usually needs to be stored for a long time, and long-term storage may lead to problems such as spoilage and oxidation of food. The corrosion resistance of tinplate can effectively protect food and prolong the shelf life of food.
2、 the sealing performance of tinplate is good. Tinplate packaging materials have excellent sealing properties, which can effectively prevent air, moisture and odors from entering the interior of the package, thereby further extending the shelf life of food.
3、 tinplate has the characteristics of high mechanical strength. The tinplate material is strong and durable, able to withstand various forces during the packaging process, and at the same time it is not easy to break, which can protect the integrity of the packaged items.
4、 tinplate is easy to process and shape, with high production efficiency and low production cost. Tinplate material is easy to process and shape, and packaging containers can be manufactured according to different shapes and sizes, with high production efficiency and low production cost.
To sum up, tinplate has many advantages as a packaging material, including good corrosion resistance, good sealing performance, high mechanical strength, and easy processing and molding. These characteristics make tinplate packaging a popular packaging material, widely used in food, medicine, cosmetics and other fields, providing reliable protection for products.
