Interactions between packaging and
foodstuffs are nothing new. In ancient times, many wealthy Romans
suffered from chronic lead poisoning because the acidic wine dissolved
the toxic heavy metal from the glazing of wine amphorae.
Packaging should not be as dangerous today
as it was, however the topic "migration" is still an on-going debate
for sealants of metal closures. So far PVC-based sealing compounds
contain phthalates or other plasticizers that are added to the
formulation to increase elasticity and workability and optimize from
nature based inherently hard and brittle materials. The downside:
These soft making additions are not included in the plastic and are
easily removed by grease or liquids. This is how they migrate from the
packaging into the filled goods. The EU identified this migration
issue at an early stage and included article three of the framework
regulation 1935 / 2004 which specifies that materials and articles in
contact with foodstuffs are not allowed to induce health hazard, any
unacceptable change in the composition of the foodstuffs and any
deterioration in the organoleptic characteristics. This directive can
only be achieved with PVC-free materials.
Sustainability in focus
Sustainability is increasingly becoming
the priority topic of companies worldwide. Conserving resources in
production as well as climate and environmentally friendly trading,
the conscious decision for the importance of sustainable packaging
continue to elevate in priority and form important purchasing criteria.
Therefore environmental hazards accruing from the manufacturing and/or
disposal process of packaging can be minimized and will eliminate
critical components that may migrate to the food or other filling
stuffs which the packaging comes into contact with. Packaging is
provided to protect the food, increase shelf life, make the foodstuffs
appetizing, make room for information and facilitate transportation.
But - despite intense contact with the foodstuffs – there can be no
interactions between them allowed.
The solution by ACTEGA
Based on the TPE-technology, which
satisfies environmental aspeccts, the PVC- and plasticizer-free
sealant PROVALIN® for all metal closures types conforms to
current EU legislation and thanks to new revolutionized migration
standards, for food safety and consumer protection. Conserving
resources, avoiding pollutive waste, reducing emissions, optimizing
processes, and saving time and money are important goals which are
consistently implemented. |
