Quality appraisal of food cans

Food cans, usually referred to as food cans, are a sealed container used to preserve food. Food cans can be sealed and sterilized to preserve food for a long time without adding preservatives, maintaining the freshness and nutritional value of food.
food cans are made of various materials, the most commonly used is tinplate, which is a thin steel plate surface coated with a layer of tin to prevent rust and provide good sealing. In addition, there are also food cans made of aluminum alloy or plastic materials, especially single-use small packages. These materials are formed into tank bodies and tank lids after being processed by molding, cleaning, sterilization and other processes.

A food company purchased 10,000 tin cans from a canning company to hold biscuits and other foods. The shelf life on the packaging is 12 months.
However, after the sales of this batch of goods, we received complaints from consumers one after another, claiming that the inside of this batch of iron cans had problems such as rust, spots, and peeling paint during the shelf life, which seriously affected the eating quality of the food.
The food company and the canning company negotiated with each other, but ultimately failed to reach an agreement on compensation. So both parties went to court, and the court commissioned an appraisal agency to conduct an investigation to confirm the quality of the batch of iron cans. The
expert team first determined how the food company used the batch of tin cans and determined that there were no improper operations that caused quality problems in the tin cans. Then the quality of the iron cans themselves was tested, and it was found that the batch of iron cans had problems such as rust, dents, and peeling paint. The peeling off of the coating was the cause of problems such as rust, dents, and other problems.
In summary, this batch of iron cans has serious quality problems, does not comply with relevant national regulations, and cannot be used as safe food containers.
