They don’t have to. Cost is a combination of the materials, manufacturing processes, distribution and marketing. On a pound-for-pound basis, PLA and Bio-PET materials cost more than their fossil fuel-based counterparts. However, our approach to combining the best materials, optimized designs and our own distribution networks means our product and packaging programs are often cost neutral to traditional plastics and sometimes less than post-consumer recycled petroleum-based (PCR) options.
