Metals, especially iron, easily react with moisture and oxygen in the air and certain ingredients in the product, causing rust or corrosion. Coatings effectively prevent moisture and oxygen from eroding the metal surface by providing a protective barrier, thereby extending the service life of the can.

Aerosol cans are usually made of metal materials, the most common of which are aluminum or tinplate (tin-plated steel). Since metals do not lose their strength and properties after melting and reprocessing, aerosol cans have a high recycling value from a material perspective.

Although tinplate cookie cans can be washed, improper cleaning methods will indeed damage the coating. Once the coating is damaged, it will not only affect the appearance of the can, but also have a negative impact on its functionality, causing the metal part to be exposed to the air and accelerating the corrosion process.

Although offset printing technology has many advantages, with the continuous advancement of printing technology, other emerging printing methods are also challenging the status of offset printing. In 2025, new technologies such as digital printing and screen printing have gradually entered the field of tinplate printing.

Correct classification: Different types of aerosol cans need to be classified and disposed of according to the nature of the contents. Emptying residues: Before discarding, ensure that the gas and chemicals in the aerosol can are completely discharged. Comply with regulations: Follow local recycling and waste disposal regulations to ensure that waste is not illegally disposed of. Support recycling: Actively participate in recycling activities to reduce resource waste and avoid environmental pollution.

At present, many well-known beverage brands in the world use tin sheet as packaging materials, especially some high-end beverages, functional beverages and canned beer, beverages, etc.

Tinplate printing is a complex process flow that usually requires multiple processes to complete. In contrast, the process flow of carton printing is relatively simple, mainly divided into two methods: flexographic printing and offset printing.

Metal can printing refers to the process of printing patterns, texts, logos, and other information on metal cans or metal materials. Unlike the printing of other packaging materials such as paper and plastic, metal can printing requires different technical processes and inks due to the particularity of its substrate to ensure the clarity, durability, and beauty of the printing effect.

Combined with the analysis in the previous article, it can be seen that the production of metal cans does rely mainly on tinplate plate. Whether from the mechanical properties, chemical stability of the material, or from its anti-corrosion and decorative characteristics, tinplate plate is an ideal choice for making metal cans.

Tinplate packaging cans can effectively isolate air, moisture, light and harmful substances, and prevent oxygen from entering the can. Oxygen is the main factor causing coffee oxidation and flavor loss, and being able to prevent the entry of oxygen directly affects the shelf life of coffee.
