BPA-Free Can Coating: What is it, and Why It’s Crucial

A BPA-free can coating is a critical component of modern food packaging. While traditional lacquers protect food from a can’s metal, concerns over bisphenol A (BPA) have driven a shift toward safer alternatives. This article explores the composition of these coatings and the health benefits of choosing BPA-free can coating products.

The Composition of a BPA-Free Can Coating

A can coating is typically a combination of resins and additives designed to protect food quality and safety. While older formulations used epoxy resins containing BPA, the new standard for a BPA-free can coating relies on safer, high-performance alternatives:

• Polyester Resins – A widely used BPA-free can coating, polyester resins offer excellent adhesion and chemical resistance without the use of bisphenols.

• Acrylics – Often used as a topcoat, an acrylic can coating provides a smooth, protective, and glossy finish. They are generally considered safe for food contact.

• Polyolefins – Polyolefins like polyethylene and polypropylene are used to give a can coating flexibility and impact resistance.

Health and Safety: The Rise of BPA-NI Lacquer

The primary concern with conventional can coatings is the use of BPA, a chemical linked to potential health issues such as hormonal imbalances. While regulatory bodies like the FDA state BPA is safe at low exposure levels, many consumers and manufacturers seek out alternatives to mitigate risk.

This is where a BPA-NI lacquer comes in. BPA-NI stands for “Bisphenol A – Non-Intent,” meaning BPA is not an intentionally added substance. UBIS has developed a BPA-NI lacquer to address these safety concerns, offering a formula that meets international standards with only trace amounts of BPA from the production process, not from direct addition.

Choosing Safer Products

When selecting canned goods, follow these tips to protect your health and support sustainable packaging:

• Look for Labels: Prioritize products specifically labeled as “BPA-free” or “BPA-NI.”

• Opt for Alternatives: Choose cans that use alternative coatings like polyester- or acrylic-based lacquers.

• Consider Fresh or Frozen: Whenever possible, buy fresh or frozen foods instead of canned goods to avoid the need for protective coatings entirely.

• Inspect Cans: Always avoid buying dented or damaged cans, as this can compromise the coating’s integrity.

In conclusion, understanding what’s inside a can is essential for making informed choices. By seeking out high-quality BPA-free can coatings and BPA-NI lacquer products, you can actively reduce your exposure to harmful chemicals and support a healthier food supply chain.
