Major food companies including PepsiCo, Mondelēz International and pladis have entered a new trial focused on flexible food packaging. The initiative involves the use of invisible digital watermarks to help improve the sorting process for recycled materials.
According to FDI Forum, these digital markers are designed to be undetectable to the human eye but can be read by sorting equipment. This technology aims to ensure that flexible plastics are more accurately identified and diverted to the correct waste streams.
