Different to the earlier technology, where liquid PVC compounds were
injected into the caps which then required high temperatures for curing, TPE
technology is supplied in granulate form and is liquefied using extrusion and
applied directly into the closure. It only requires formation after application
and does not require curing. This saves energy, reduces CO2 emissions and
reduces production costs effectively. The energy required to process PVC
plastisols is higher than manufacturing TPE granulates. Working with granulate
is a lot cleaner, and generates less waste. Therefore implementing this
procedure meets the requirements of sustainable production and resource
conservation highly.
Due to the fact that there is no liquid plasticizer for flexibility/elasticity
being used, the TPE granulates minimizes the potential risks for migration of
undesirable substances. When there is nothing in it, there can be no extractions
and therefore no migrations into the filled goods. Thus the demands for pure
foods, safety and consumer protection can be realized.
With the use of TPE technology in the field of lug and twist off metal
closures not only meets the stringent new specifications for all filling goods,
but once again underlines the competence of ACTEGA DS in offering innovative
solutions to the closure industry. |
