The manufacturing process of beverage cans requires thermal control to check the welding spots. All the parts must be welded properly to perfectly preserve the product the can will contain. To ensure maximum watertightness, the batches of cans enter a flame inline furnace that will progressively raise the temperature to 250 °C.
By marking one or more of the cans with heat-sensitive labels before they enter the inline furnace, we will be able to check the temperature reached during the process easily. When the cans come out of the furnace, the labels indicate the maximum temperature the cans were subjected to.

Clock-type irreversible thermometer with 5...Quality control in the manufacture of food cans is an essential requirement for health reasons. In the manufacturing processes of any elements or accessories related to consumer products or items that come into contact with living beings, making sure that they comply with current regulations is necessary. Health requirements, HACCP protocols, etc. have been revised and perfected in recent times to prevent the development of viruses and bacteria due to undesirable contamination in packaged products.
A food can that has deteriorated or been damaged by faulty welding can be particularly dangerous for consumption. The germs that develop inside it could pose a threat to living beings and even be fatal.
The improvement of these containers – besides the use of new lighter metals, stainless metals like aluminium, and less rigid and alterable like brass – is largely due to better quality control.
Self-adhesive temperature labels have contributed to a much more reliable and accurate temperature reading. They are a more cost-effective solution than other sensors
