Flexibles out-score rigids

The study included eight packaging systems consisting of six deli meat packages and two breakfast cereal packages. The packages included both flexible packaging formats with resealable closures as well as rigid packaging formats. 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. ‘Inspired by the packaging industry’s commitment to a greener future, Zip-Pak is likewise dedicated to the issue of sustainability and is mindful of its own environmental footprint,’ says international sales & marketing director Bob Hogan.

‘These research findings will encourage future developments to help reduce the environmental footprint of packaging, including packaging that incorporates next generation materials, films and closures.’ Outlining possible future development projects, Bob Hogan picked out the possibility of combining oxygen scavengers into the zipper flange; adding a scent or aroma to the zipper to compensate for an estimated 70% reduction of content taste due to internal packaging; and the possibility of incorporating electronic circuitry, tamper evident mechanisms, temperature sensors or RFID solutions within zippers. ‘Packaging features that provide additional value such as convenience, increased freshness or shelf differentiation are ways to encourage brand preference in slowing economies,’ points out Hogan. ‘Thinking about ways to connect with the consumer and enhance
their experience with the product will keep brand managers one step ahead.’
