It is crucial to ensure packaging stability and product-packaging interaction.
Migrations studies guarantee the product can not be contaminated by packaging residues. Furthermore, the evaluation of packaging-product interactions indicates whether the packaging is degraded or the product properties are damaged due to contact between them.
On the other hand, the corners where residues could be accumulated must be avoided in order to prevent contamination sources.
Thermography allows the evaluation of the packaging sealing with a film closure, avoiding internal atmosphere modifications due to external conditions.
