The debate between metal and plastic packaging is one of the most common in companies strategic decisions. But beyond clichés, what is the reality when we analyse costs, benefits, and long-term impact?

At Boixadós, with decades of experience in industrial packaging, we present a comparison based on real data.

Although plastic may seem cheaper per unit, a full analysis shows that metal packaging delivers better performance, durability, and long-term sustainability.

The real costs reveal clear advantages for metal: its strength reduces losses and returns, its stackability optimizes transport and storage, and its barrier against light and oxygen extends product shelf life by up to 50%.

From an environmental perspective, the difference is even more striking. Both aluminium and steel have recycling rates of 82% and can be recycled indefinitely, while plastic barely reaches 42% and loses quality with every cycle.

Consumer perception also plays a role: metal packaging is associated with higher quality products, food safety, and environmental commitment — aspects that strengthen brand image and premium positioning.

In conclusion, rather than simply choosing between metal or plastic, companies should consider which type of packaging best aligns with their business strategy and sustainability values.

When total cost and global impact are taken into account, metal stands out as a competitive and responsible choice.
