Steel food and beverage cans are generally coated with a lacquer to provide improved food preservation. These “epoxy-type” lacquers, until recently mainly based on bisphenol A (BPA), applied to tinplate have been used very successfully for many years. However, due to recent (food) safety concerns about the use of BPA lacquers, legislation has been introduced in Europe banning its use in cans. Obviously, the result of the new legislation and public sentiments is that brand owners are demanding cans with a BPA-free coating.
Polyester laminates (like Tata’s Protact material) are uniquely suited to solve all current (BPA) and future food safety issues. Next to these aspects, Protact also has a strongly positive effect on VOC emissions, water usage and CO2 footprint at the canmaker. With large new investments being realised at Tata Steel, the understanding of material properties is essential for Tata Steel to support the use of Protact in the market. The theme of this proposal is to optimize performance of Protact during processing at customers in processes such as cutting and stacking. Due to the different friction and surface properties of Protact compared to the classic materials, the mobility of the sheets is different and sheets of Protact tend to stick together resulting in sub-optimized stacking behavior of the sheets and/or bad de-stacking when the sheets are further fed to presses, to be converted into final product. This effect could be related to the actual interaction between the sheets, but also effects like static loading can play a role. Once the mechanism is understood and a suitable measuring method developed, also formulation and optimization of the coating would be part of the project.
