A tin can is a popular type of container that is often found on the shelves of modern stores and supermarkets. Some products of this type are decorated as brightly and colorfully as possible, others are simpler and more restrained, but all equally attract the attention of buyers. Such packaging is completely sealed and very convenient for storing goods. But putting any information on it is not easy.
Most of the cans produced today are used for alcoholic and non-alcoholic beverages. Some products are used for peas, corn, canned meat and fish, and other types of food products. It doesn't matter what is in the bank - according to the rules of the law, in any case basic information should be reported on it. These are the composition, manufacturer, date of manufacture, expiration date, storage conditions.

For marking, they resort to specialized methods and specific equipment. Information is displayed in text or letter form. They comply with the norms prescribed in the current legislation. Labeling is necessary to satisfy the consumer's right to detailed information about the product.
Every manufacturer must follow legal requirements when placing data on a product.

- capacity. It is necessary to prescribe the nominal value;
- special character assigned to food;

It is important to provide as much information as possible about the manufacturer. This is the name, the country in which the product is released, the legal address of the manufacturer.
