Unlike many disposable plastic packaging, tinplate packaging cans have a very high recycling value. It is a 100% recyclable material that can be recycled many times. This feature makes tinplate packaging cans an ideal environmentally friendly packaging choice.

Tinplate aerosol cans themselves are tin-plated. The tin layer as a protective coating can enhance its corrosion resistance to a certain extent, but this coating also has limitations. Not all acid and alkali liquids can be in contact with it for a long time without reacting.

For tinplate manufacturers, the price of raw materials accounts for a considerable proportion of production costs. The price fluctuations of steel and tin not only directly increase production costs, but may also affect the stability of the entire supply chain.

Differences in coating metals The most fundamental difference between tin-plated steel and galvanized steel lies in the difference in their coating metals. Tin-plated steel is coated with tin, while galvanized steel is coated with zinc.

Tin packaging usually refers to various can-shaped packaging containers made of tin-coated steel sheets (tinplate) or other types of thin steel sheets. The most common material in tin packaging is tinplate, which is a thin layer of tin coated on the surface of the steel sheet.

If it is a large-area spraying job, such as architectural painting or automotive painting, you can choose a large-capacity paint aerosol can; for small furniture, decoration or handicraft spraying, you can choose a small-capacity aerosol can.

As a strong and stable metal material, tin plate sheet can effectively prevent the influence of oxygen, moisture, ultraviolet rays and other factors in the air on cosmetics. Through good sealing and impermeability, tin plate sheet packaging can minimize the contact of cosmetics with the external environment, thereby extending its shelf life.

Although the production process of tinplate packaging cans still requires energy consumption and generates carbon emissions, compared with aluminum alloys, the production process of tinplate packaging cans is more energy-efficient and environmentally friendly, and its recycling process has a lighter burden on the environment.

There are many types of anti-corrosion coatings for printing tinplate cans on the market. Common types include epoxy resin coatings, polyester coatings, polyurethane coatings, and fluorinated coatings. Different types of coatings have certain differences in anti-corrosion performance, high temperature resistance, and chemical resistance.

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.
