Bisphenol A (BPA)-based epoxy coatings are the most commonly used protective lining for metal food and beverage packaging. BPA-free campaigns from organizations such as the Breast Cancer Protection Partners, Clean Production Action and the Natural Resources Defense Council have raised awareness of and consumer demand for BPA-free products.
Consumer-facing food processors, can manufacturers and others who have relied on epoxy-lined cans for decades need to respond, but face the challenge of finding safe substitutes for BPA-based coatings that provide all the same functional benefits at reasonable cost.
