Coating

By Alucan Editorial Team | Updated: August 2026 | ISO 9001 / FSSC 22000 certified

Food-contact linings that protect both the beverage and the can, matched to regional regulatory requirements.

Internal Coatings & Linings for Aluminum Cans

Internal coatings protect both the beverage and the aluminum can. Without a protective lining, acidic or aggressive products could react with the metal, affecting taste, safety and shelf life.

Main Coating Types

Coating	Base Chemistry	Best For
Epoxy-Phenolic	Epoxy-phenolic resin	High-volume industrial markets, acidic beverages
BPA-NI	Acrylic/polyester cross-linked	North America, European Union, regulated markets

Why BPA-NI Matters

BPA-NI (Bisphenol A Non-Intent) coatings are formulated without intentionally added BPA. They are increasingly required by regulators and major retailers in North America and Europe. Alucan can supply BPA-NI internal linings with supporting migration test reports.

Coating Application

Coating is sprayed inside the formed can body.
Cured in high-temperature ovens to form a continuous film.
Tested for coverage, weight and adhesion.
Matched to product pH, carbonation and pasteurization conditions.

Certifications

We provide SGS food-grade migration reports and can align with ISO 9001, FSSC 22000 and market-specific food-contact regulations.

Frequently Asked Questions About Can Coatings

What is BPA-NI coating?

BPA-NI stands for Bisphenol A Non-Intent. It means the coating is formulated without intentionally adding BPA. BPA-NI linings are required or preferred in North America, the European Union and by many major retailers.

Is epoxy-phenolic coating safe for beverages?

Yes. Epoxy-phenolic coatings are widely used in industrial beverage can markets and provide excellent protection against acidic and aggressive products. They are cost-effective for high-volume applications where BPA-NI is not mandated.

Which coating should I choose for my market?

Choose BPA-NI for North America, the EU and regulated retail chains. Choose epoxy-phenolic for cost-sensitive industrial markets where local regulations permit. We provide migration test reports to support either choice.

How is internal coating applied?

The lining is sprayed inside the formed can body and cured in a high-temperature oven to create a continuous protective film. Coverage, weight and adhesion are tested as part of our quality control process.

Do coatings affect beverage taste?

When correctly matched to the product, the coating prevents metal contact and preserves taste. We select coatings based on pH, carbonation, pasteurization and shelf-life requirements to ensure flavor stability.

Why Internal Coatings Matter

Aluminum is chemically reactive with acidic and aggressive beverages. Internal coatings create a barrier that protects both the beverage and the can, ensuring shelf stability, taste integrity and food safety. The wrong coating can lead to corrosion, off-flavors or regulatory rejection in key export markets.
