Tinware Direct’s tins are coated with a lacquer to protect them from environmental degradation, which helps prevent rusting. However, it’s recommended to avoid using tinplate products for water-based items and instead opt for aluminium, which is highly resistant to corrosion. Additionally, storing tins in high moisture environments, freezers, or very high temperatures can degrade the lacquer and potentially lead to rust. We recommend testing a sample first to ensure you’re satisfied with how our packaging complements your product.
