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. 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 emphasizes
the competence of ACTEGA in offering innovative solutions to the
closure industry.
