Since 2019 when the first generation of “hero samples” recycle ready mono-material stand-up pouches were presented, BOBST and Brückner Maschinenbau, along with the other project partners comprising polymers and consumables suppliers, have reportedly made significant achievements in the mission to develop solutions that help the meet the industry’s pledges about packaging sustainability.
Within the ecosystem of partners involved, the contributions of Brückner Maschinenbau and Bobst in the development of a series of new generation high barrier mono-material laminated BOPE-based structure for sustainable flexible packaging solutions have been in the field of film technology and in their functional properties and end-to-end processability respectively.
Bobst’s Competence Centers have been used to test the viability of the new substrates, which differ from conventional ones in terms of machinability. Because Bobst can offer all technologies for production of flexible packaging, from vacuum metallizing and coating, through to gravure, CI and inline flexo printing, to lamination, it had been possible to check and validate the given requirements at every stage of the production process.
Since the first generation of Hero Samples, the partners involved have continued their investment and R&D research to progress the sample further. Latest hero samples 3.0 include full PE and PP monomaterial structures with option of AlOx transparent metallizing or AluBond opaque metallizing, or conventional metallizing, using barrier adhesives, to achieve flexible packaging structures offering high and ultra-high barrier protection levels.
