Printed tinplate, as the name suggests, is a technical application that prints patterns, texts, logos and other contents on the surface of tinplate through a special printing process. Several main purposes of printed tinplate: 1. Enhance the visual appeal of the product 2. Provide brand promotion and identification 3. Deliver product information and instructions for use 4. Improve the anti-counterfeiting ability of packaging 5. Protect the tinplate surface and improve durability

Tinplate products in food packaging: 1. Tinplate packaging in canned food ● Canned food ● Canned soup and liquid food ● Canned high-acid food 2. Tinplate products in beverage packaging ● Metal beverage cans ● Tea cans and coffee cans 3. Tinplate products in candy and snack packaging ● Candy boxes ● Biscuit and cake cans ● Potato chip cans 4. Tinplate products in dairy and milk powder packaging ● Milk powder cans ● Dairy packaging cans 5. Tinplate packaging for condiments and oily foods ● Condiment cans ● Edible oil packaging cans

Mechanical grinding is one of the most common rust removal methods, which mainly removes rust on the surface of tinplate sheet by physical means. Commonly used tools include sandpaper, wire brushes, polishers, etc.

Tinplate is actually a composite material, its core part is low-carbon steel plate, and the surface is plated with a thin layer of tin. Therefore, tinplate is mainly composed of two materials: steel plate (iron) and tin.

For the question of "Is tinplate packaging can flammable?", we can get the answer from the properties of its main materials. Generally speaking, metal materials are not flammable because they do not contain flammable components such as hydrocarbons

International price distribution of electrolytic tinplate: 1. The price range per ton in the Chinese market is between 6,000 yuan and 8,000 yuan 2. The price per ton in the European market is usually between 900 euros and 1,200 euros 3. The price per ton in the North American market is about 1,000 US dollars to 1,300 US dollars 4. Other regions are about 800 US dollars to 1,000 US dollars per ton

The main advantages of tin can packaging: Excellent protective performance Excellent sealing Good plasticity and diversity Environmental protection and recyclability Anti-tampering and authenticity functions The main disadvantages of tin can packaging: Heavy weight High production cost Easy to rust Difficult processing Poor transparency

The main component of tinplate cans is steel, on which a thin layer of tin is coated to prevent rust and corrosion. Aluminum cans are made entirely of aluminum, a lightweight metal with a density of about one-third that of steel.

The black marks in tinplate cans are usually caused by corrosion of the can. When the metal in the can reacts with the acid in the food or environment, corrosion occurs, resulting in black marks in the can.

The tinplate layer on the surface of tinplate sheet has good chemical stability and usually does not react chemically with food or beverages. This is because tin has extremely low reactivity at room temperature and is not easy to react with acids and alkalis, so it is widely used in food packaging.
