New bottle-to-bottle technology by Erema

This is made possible by the combination of Vacurema technology and vacuum-assisted Solid State Polycondensation (SSP) to create a process in which all thermal process steps are performed in a nitrogen and/or vacuum atmosphere.

The Vacunite process is based on the combination of Vacurema technology – which has been proven over the past 20 years and has been further developed for this application – together with newly patented vacuum-assisted Solid State Polycondensation (SSP), which Polymetrix developed for Erema for this application.

What makes this combination so special is that all thermal process stages take place in nitrogen and/or vacuum atmosphere, largely eliminating undesirable flake and pellet discoloration and reliably removing additives which could lead to unfavourable reactions in the melt. Another benefit of Vacunite: the nitrogen used in the SSP is cleaned and can be fed back into the previous processing stage so that nitrogen consumption is reduced as a result. To increase the transparency of the preforms, the pellets are dedusted again before filling.

Overall, the technology requires 40 percent fewer components, making the plant much more compact at the same time as consuming up to 36 percent less energy than comparable systems on the market.
