Packaging
An adequate packaging is of highest importance for foodstuff in order
to shield it from external influences. With respect to tea and coffee,
the product is easily affected by light and air which may lead to
changes in taste and colour. Hence, a packaging should prevent light
and air to get to the product. However not only the external influences
have to be taken account of. The scents and aromas of the teas or
coffees may exit the package which has to be prevented in order to
ensure a consistend quality level.
