Understanding the challenges and solutions for manufacturers of metal cans

The Metal Cans category of packaging was invented in the beginning of the nineteenth century and has been used for more than 100 years. With time, its scale of use expanded into a variety of end-use commodity packing purposes such as food & beverage items, chemicals, oil etc.

 Over the years, many improvements have been made to the design: materials used for the cans such as aluminum, steel, tin and internal/external protective organic coatings; manufacturing equipment for 2 and 3 piece cans; chemical process monitoring; applications like food & beverage, edible oil, pharmaceutical industry, personal care, and cosmetic products, industrial chemicals; and, quality control methods/instrumentation.

Today, due to the relentlessly growing global demand and production of millions of cans per day around the world, manufacturers are faced with the challenge of increasing production efficiencies to provide cost-efficient and scalable solutions. This means higher production speeds resulting in a higher number of units being produced per minute and huge numbers being transported worldwide. The manifold manufacturing process in the canning industry makes the entire metal can production complex and can involve quite a few machines from splitting to seaming.

The can manufacturing plants and their raw material suppliers are responsible for product integrity even before the distribution of the cans to the product manufacturers. Therefore, outgoing complete quality control of produced empty cans is an extensive practice at manufacturing locations. This control provides the possibility of eliminating package issues before they reach the filling process through scrupulous quality control procedures.

The quality testing of empty cans by manufacturers and of filled and finished cans help to act proactively by eliminating production challenges like:

→ Downtime during the filling process, leaks, and spillage.

→ Lengthy production time: formerly tested packaging will help save time during the production process.

→ Contamination and unsafe-to-use products leading to a product recall.

Hence, both empty can package testing and filled can quality testing is an appropriate choice for manufacturers. This will help to offer safe and sterile products contained within the metal cans.
