EFSA said the expert panel tasked to evaluate the safety of the mon plastic additive found that the human body rapidly metabolizes and eliminates BPA, and therefore it presents no risk to infants, children, or adults. The conclusions from those studies and prehensive safety evaluations by government bodies worldwide are that polycarbonate bottles are safe for consumer use, states the International Bottled Water Association (IBWA). Flexible vs. rigid RESEARCH findings on the relationship between flexible packaging and sustainability by Franklin Associates, an independent third party research firm, demonstrates the smaller environmental footprint of flexible resealable packaging as pared to rigid alternatives, according to ZipPak. The life cycle inventory (LCI) included eight packaging systems (flexible packaging formats with resealable closures as well as rigid packaging formats) consisting of six deli meat packages and two breakfast cereal packages. Key findings of the LCI include that products packaged in flexible pouches with resealable closures had lower energy consumption, solid waste generation, and greenhouse gas emissions than the rigid systems included in the analysis. Further, although transportation energy accounted for less than 17% of total energy for all systems, the results show that transportation energy requirements for the reusable rigid containers are higher than those for the flexible packaging systems. IBWA says in its website that 100% of bottled water containers are recyclable, where facilities exist ?that caveat is important because very few countries have legislated recycling and have the facilities to process plastic packaging. Containers for bottled water, made from PET plastic, which are being increasingly lighter in weight, accounted for less than onethird of one percent of all waste produced in the United States [the world39。s environmental footprint is source reduction, reports PMMI in its latest Intelligence Brief on Packaging Trends. Source reduction, such as lightweighting containers and closures, eliminating secondary packaging, and replacing rigid packaging with flexible packaging, not only consumes less materials but also helps packages cut costs across the supply chain or offset price increases. While packagers do not necessarily practice source reduction because of sustainable concerns, in the end using less packaging also helps the environment. When multiplied by millions of containers and closure, even small weight reductions add up to a significant amount of resin and can help control or even reduce packaging and distribution costs. In addition, if the lighter
