Why Do I Need Corrosion Testing for My Product?

Corrosion Testing for Non-Beer Products
At East Coast Canning & Printing, we don’t conduct corrosion testing in-house, but we guide customers through the process and requirements before packaging into aluminium cans.

If you are producing a non-beer beverage, corrosion testing is expected to be completed to confirm compatibility between your product and the can lining.
What Is Corrosion Testing?
Corrosion testing is a laboratory assessment that determines how your beverage interacts with the protective internal lining of an aluminum can. It helps identify risks to can integrity, product stability, and shelf life.
As the ready-to-drink category expands into seltzers, RTDs, kombucha, cold brew, functional beverages, and alcohol-free drinks, it’s important to understand that not all liquids behave the same inside aluminum packaging.
Why Corrosion Testing Matters
Beer is generally predictable in cans. Many non-beer beverages are not. Differences in acidity, sugar, juice content, botanicals, alcohol base, carbonation, and manufacturing processes can all influence how a product interacts with can linings.
Corrosion testing provides a technical risk profile rather than a simple pass or fail. This allows beverage producers to make informed decisions around formulation, shelf life, manufacturing practices, and packaging options.
What Corrosion Testing Evaluates
Testing typically assesses:
• Acidity and chemical composition
• Dissolved oxygen levels
• Shelf life risk indicators
• Manufacturing and filling processes
Sample handling also plays a role. Samples provided in small glass bottles with minimal headspace often produce more reliable results by reducing oxygen exposure.
Corrosion Testing = Confidence Before Production
Packaging into aluminum cans combines chemistry and engineering. Corrosion testing helps prevent unexpected packaging failures, supports production planning, and protects product quality.
Whether you’re canning RTDs, kombucha, soft drinks, cocktails, or functional beverages, corrosion testing is one of the most effective ways to safeguard your product and brand.
