In this paper we have shown that one of the most important characteristic of a packaging is protection of the wrapped product from the influences of the outer. A special emphasis has been put on the analysis of the importance of a packaging in the preventing steam and oxygen harm the product itself.

External corrosion of tinplate cans containing food products, although less frequent and comparatively less dangerous than internal corrosion, should anyhow be studied more in depth, since the consumer requires not only high-quality products, but also cans having a good appearance. The objective of this experimental work was to study the influence of the main ions present in cooling waters on the corrosion of metal food cans. After a short introduction on tinplate corrosion phenomena and on the chemical and processing factors affecting it, the results are shown which were obtained from electrochemical corrosion trials performed using model solutions at various concentrations as well as cooling water samples directly taken from food plants. This research work yielded information on the corrosion mechanisms (extent and morphology) of the various species and parameters affecting the aggressivity of industrial waters (presence of additives, free chlorine content and conductivity) | La corrosione esterna delle scatole di banda stagnata contenenti prodotti alimentari, sebbene meno frequente e relativamente meno pericolosa della corrosione interna, deve comunque essere oggetto di maggiore attenzione, in quanto il consumatore richiede, oltre a prodotti di alta qualita', contenitori di aspetto accettabile. Oggetto del lavoro sperimentale e' stato lo studio dell'influenza dei principali ioni presenti nelle acque di raffreddamento sulla corrosione delle scatole metalliche per alimenti. Dopo una breve introduzione sui fenomeni di corrosione della banda stagnata e sui fattori chimici e di processo che la condizionano, il lavoro illustra i risultati ottenuti nelle prove di corrosione elettrochimiche effettuate con soluzioni modello a diverse concentrazioni e con acque di raffreddamento prelevate direttamente presso industrie alimentari. A conclusione della ricerca sono state ottenute informazioni sul meccanismo di corrosione (intensita' e morfologia) delle diverse specie e sui parametri che influenzano l'aggressivita' delle acque industriali (presenza di additivo, concentrazione di cloro libero e conducibilita')

Cools, F.
Les possibiltés variées d'utilisation des plastiques, leurs qualités d'adaptation, leur facilité de transformation et leurs avantages technologiques les ont fait rechercher, en particulier dans les secteurs d'activité touchant à l'emballage des denrées alimentaires et au conditionnement de l'eau. Afin de mieux comprendre les choix effectués pour préserver la santé de l'homme, on a rassemblé dans cet article les bases réglementaires, les procédures d'élaboration de la réglementation, son état d'avancement, ses perspectives, etc., dans les domaines d'application qui viennent d'être rappelés
