When making cookie packaging tins, the size of packaging tins must be determined first. The choice of size not only directly affects the cost of packaging, but also the performance of the product in the market.
In addition to tin plating, tinplate sheet manufacturers can also use other surface treatment methods to enhance the durability of the product. For example, some tinplate sheet manufacturers use anti-corrosion coatings (such as epoxy resin coatings, polyester coatings, etc.) to provide additional protection for tinplate sheet.
As the main material of tinplate plate, low carbon steel itself has the natural color of metal, usually showing a silver-gray or iron-gray metallic luster. This color of the steel surface comes from the essential properties of its iron element, and usually has a strong reflective effect.
Tinplate plate is not actually aluminum, but a steel with a tin coating. Although it is different from aluminum, like aluminum, tinplate plate is also a recyclable material. Let's learn more about tinplate plate and aluminum.
The production of tinplate sheet can be traced back to Europe, and the earliest production history can be traced back to Germany in the 16th century. Although the concept of tinplate sheet was widely spread and gradually improved in the later period, its true birthplace is generally believed to be Saxony, Germany, where tinplate plate was first systematically produced.
The main advantages of electrolytic tinplate sheet:
1. The thickness of the tin layer is uniform and easy to accurately control
2. Low tin consumption and material saving
3. The surface of the coating is smooth and suitable for fine printing
4. Strong corrosion resistance
5. Suitable for a variety of subsequent processing techniques
6. Better environmental protection
Biscuits are a kind of snack food loved by consumers, and their shelf life is relatively long, so the requirements for packaging are also relatively high. In order to ensure the taste and freshness of biscuits and prevent moisture and deterioration, cookie packaging tin must have excellent sealing, barrier and durability.
As the core material of 320ml aerosol tin cans, tinplate sheet has become the preferred material for aerosol can manufacturing due to its strong corrosion resistance, superior mechanical properties and good environmental protection. Tinplate sheet itself is a thin steel plate coated with a tin layer.
Tinplate sheet prevents rust by plating a layer of tin on the surface of the steel plate to form a physical barrier to prevent the steel from contacting with air and moisture. The thickness and uniformity of the tin layer play a vital role in the anti-rust performance of tinplate sheet.
During World War II, there was a shortage of tinplate sheet, which prompted people to look for alternative materials to meet packaging needs. During this period, aluminum became the main alternative material for the manufacture of seamless can-shaped packaging containers.
