One of our clients mentioned that he was not satisfied with the topseal film, they used for the topsealing
of trays concerning ready-meal components.

They wanted one type of film with the following properties:

• Perfect peelability in hot and cold conditions, without leaving any sealing residues
  (read sealing hairs) on the edges of the trays.

• Perfect anti-condensation properties during the hot packaging of the products,
  as well as after cooled conditions in the stores.

• Good transparency and haze and a film which would not rupture or break by peeling the film
  from the tray, in other words: strong and tough enough.

• Good barrier properties.

• Visual a very tight and smooth packaging.

Our customer had tried many different laminates and various film combinations but the combination
of required and desired properties was never reached.

Our solution:
After consulting one of our producers, we started with the development of a totally new so called cast film.
It was of great interest to guarantee to our customer all requested conditions at different temperatures
and circumstances.

At first we developed a film that already had a part of these required properties.
After extensive testing and lab studies, we finally could optimize this together with
the anti-condensation properties and the peelability of this film.

Finally, we added a so-called ‘’light shrink additive’’ to the film, to ensure that it could be sealed tightly
and smoothly on the trays.
