In this study, commercially available isotactic polypropylene (PP) and nylon-6 (PA6) blends and laminates were prepared, to develop a material with optimal water vapour and oxygen barrier properties. The effect of compatibilizers on phase dispersion has been investigated using three commercial Polybond's, PB3002, PB1001, and PB3009. Three compatibilizers prepared in-house were also used as, maleic anhydride(MA) grafted on PP, MA and butyl methacrylate(BMA) co-polymer grafted on PP, and BMA grafted on low density polyethylene. The effect of two silanes( methacrylate functional and vinyl functional) on PP were also investigated and also the plasticization of PA6 with formic acid. The results were compared with a commercial blend of PP and PA6, Orgalloy R-6000. Light microscopy with phase and fluorescence contrast has been used for morphological evaluation. Chemical changes were studied by Fourier Transform Infrared Spectroscopy and rheology by dynamic and steady state measurements. Barrier properties were determined gravimetrically for water vapour and organic solvents, and for oxygen by an Oxtran apparatus. The results have shown that phase dispersion can be more easily explained by molecular interactions than by the rheological parameters. The blend slip factor has been improved however by compatibilizers and consequently the phase dispersion, which had little effect on the barrier properties of the blends and indeed the laminates were more effective water vapour barriers. The availability of particular functional groups, which can interact with the permeant is the most important parameter, which can be affected by processing and blending conditions. The addition of hydrophobic functional groups into polypropylene was therefore the most effective method for enhancing the barrier properties of polypropylene. Cross-linking of the matrix polymer has improved the barrier properties to a lesser extent. It has also been shown, that PP solvent permeability (particularly di-chloromethane) can be improved, by silane addition.

Thermal spray coatings offer new alternatives in the production of electronic power modules that use alumina ceramic as an isolation layer. Current processes use direct bond copper (DBC) soldered to a nickel plated copper heat spreader. A coefficient of thermal expansion (CTE) mismatch exists between copper and alumina and leads to reliability issues that arise due to product failure during thermal cycling and lifetime operation. The substitution of an AlSiC metal matrix composite (MMC) heat spreader baseplate addresses the problem of CTE mismatch and will reduce the number of product failures related to cracking and delamination caused by this pronounced mismatch in the thermal expansion coefficient..
The substitution of an AlSiC (MMC) heat spreader baseplate also allows the production process to be achieved with a fewer number of metallization layers. Thermal spray can apply alumina ceramic coatings directly to the AlSiC (MMC) baseplates. A reduction in process steps will lead to a reduction in manufacturing costs, the main driving objective in Microelectronics Industries.
Thermal spray coatings have a major problem since they have a porous microstructure which can trap undesired moisture. The moisture basically causes the coatings to have a lower dielectric breakdown voltage and a higher leakage current at normal operating voltages. This problem can be eliminated by manufacturing the electronic power modules in a controlled environment and packaging the devices in a hermetically sealed package.
This thesis analyzes the data obtained from direct-voltage dielectric breakdown and direct-voltage leakage current tests conducted on coupons manufactured using the thermal plasma spray coating process and the thermal high-velocity oxyfuel (HVOF) coating process. ASTM specifications defining appropriate testing procedures are used in testing the dielectric strength of these coupons.
Issues relating to the dielectric strength and dielectric leakage current are evaluated and validated at the Microelectronics Laboratory at Virginia Polytechnic Institute & State University. The objective to conduct this research study using plasma and HVOF alumina coatings as dielectric isolation layers is to support the Microelectronics Industries in developing a product with increased reliability at a lower manufacturing cost.Master of Science

Le projet consiste à développer des filtres à iode à base de phosphates d'argent ou de vanadates de plomb afin de capter et de conditionner des déchets ultimes. Les filtres à iode actuels, à base d'alumine ou de silice, nécessitent en effet des traitements complexes, sources de déchets secondaires, pour assurer une forme compatible avec les conditionnements envisagés. Plutôt que de qualifier de nouveaux matériaux de conditionnement adaptés à ces filtres, une solution pragmatique consiste donc à développer des filtres qui soient, à une étape de traitement thermique près, un précurseur de la matrice de conditionnement. Au travers de cette thèse, on se propose d'élaborer des supports à porosité contrôlée/hiérarchique à base majoritaire de phosphate d'argent ou de vanadate de plomb. Dans les matériaux à porosité hiérarchique, les espèces sont d'abord transportées dans les macropores, passent ensuite dans les mésopores pour accéder finalement aux micropores. Il est donc essentiel de maîtriser la structure porale initiale en fonction des différentes conditions de synthèse. Ces supports seront ensuite fonctionnalisés pour générer des sites actifs, à base d'argent dans le premier cas et à base de plomb dans le second, pour la capture de l'iode. Les supports fonctionnalisés seront ensuite testés sur un banc de capture de l'iode avec de l'iode 127, stable, dans différentes conditions pour qualifier l'impact de différents paramètres sur l'efficacité de capture. Après avoir été chargés en iode jusqu'à atteindre leur capacité maximale de fixation, la transformation des filtres en matrice de conditionnement par traitement thermique sera étudiéeThe project involves the development of iodine filters based on silver phosphates or lead vanadates to capture and package ultimate waste. The current iodine filters, based on alumina or silica, require complex treatments, sources of secondary waste, to ensure a compatible form with the contemplated packaging. Rather than qualify new conditioning materials adapted to these filters, a pragmatic solution is therefore to develop filters which are, at a heat treatment step, a precursor of the conditioning matrix. Through this thesis, we propose to develop porous supprt controlled/hierarchical majority based on silver phosphate or lead vanadate. In materials with hierarchical porosity, the species are first transported in the macropores, then pass into the mesopores to finally reach the micropores. It is therefore essential to control the initial pore structure according to the different synthesis conditions. These supports will then be functionalized to generate active sites, based on silver in the first case and lead based in the second, for the capture of iodine. The functionalized supports will then be tested on an iodine capture bench with stable iodine 127 under different conditions to qualify the impact of different parameters on the capture efficiency. After having been loaded in iodine until reaching their maximum fixing capacity, the transformation of the filters into a conditioning matrix by heat treatment will be studied

Les packagings d’électronique embarquée sont actuellement en alliages d’aluminium. A partir d’une étude de sélection des matériaux, complétée par une simulation numérique thermique,nous avons démontré qu’un matériau composite constitué d’une matrice aluminium et de fibres de carbone à forte conductivité thermique, représente un fort potentiel de gain de masse sur ces équipements. Cependant, le couplage de ces deux matériaux génère des problèmes d’élaboration en raison d’incompatibilités fortes parmi lesquelles un mouillage très faible du carbone par l’aluminium liquide et une réactivité chimique élevée qui conduit à la formation de carbures d’aluminium préjudiciables pour le matériau final. Deux voies d’élaboration distinctes ont été envisagées : Une voie liquide où l’utilisation d’un agent de mouillage (un sel fluoré) a permis d’obtenir la montée par capillarité du métal dans des mèches de fibres. Une voie solide basée sur une technique originale d’empilements de feuillets d’aluminium et de fibres de carbone avec le procédé de Spark Plasma Sintering (SPS). .La seconde technique s’est révélée prometteuse en permettant d’obtenir des échantillons multicouches sans porosités, un endommagement très limité des fibres et une architecture contrôlée.Notre étude a montré que la formation de carbures d’aluminium est limitée. De plus, une meilleure compréhension du SPS ou l’application d’un revêtement sur les fibres devraient permettre d’éviter la formation de ces carbures. Les tentatives de caractérisations mécanique et thermique effectuées sur ces échantillons donnent un premier aperçu de l’efficacité du renforcement de l’aluminium par les fibres de carboneEmbedded electronic packagings are currently made of aluminum. A first study – basedupon a material selection method completed by numerical analysis – showed that a metal matrixcomposite made of aluminum and highly thermal conductive continuous carbon fibers represents ahigh potential upon weight savings for those equipments. Though, coupling these componentsrepresents numerous challenges due to their incompatibility such as a really low wetting of carbonliquidaluminum system and its unavoidable chemical reactivity that leads to the formation ofaluminum carbides that are harmful for the final material. Two manufacturing routes were considered: A liquid route using a wetting agent (fluorinated salts) led the metal to rise alongcarbon fibers by capillarity. A solid route based upon a novel technique of aluminum foils and carbon fibersstacking using the Spark Plasma Sintering (SPS) process.This second technique revealed to be very promising and allowed to obtain multilayer samples with noporosities, highly limited fiber damages and controlled composite architecture. Our study shows thataluminum carbides formation is limited. Moreover, a deeper comprehension of SPS process or thedeposit of fiber coatings would prevent this carbide formation. Attempts of mechanical and thermalcharacterization led upon such samples give a first overview of the efficiency of the aluminumreinforcement by carbon fibers

Compared to other, plastic materials have registered a strong acceleration in production and consumption during the last years. Despite the existence of waste management systems, plastic_based materials are still a pervasive presence in the environment, with negative consequences on marine ecosystem and human health. The recycling is still challenging due to the growing complexity of product design, the so-called overpackaging, the insufficient and inadequate recycling infrastructure, the weak market of recycled plastics and the high cost of waste treatment and disposal. The Circular economy package, the European Strategy for plastics in a circular economy and the recent European Green Deal include very ambitious programmes to rethink the entire plastic value chain. As regards packaging, all plastic packaging will have to be 100% recyclable (or reusable) and 55% recycled by 2030. Regions are consequently called upon to set up a robust plan able to fit the European objectives. It takes on greater importance in Emilia Romagna where the Packaging valley is located. This thesis supports the definition of a strategy aimed to establish an after-use plastics economy in the region. The PhD work has set the basis and the instruments to establish the so-called Circularity Strategy with the aim to turn about 92.000t of plastic waste into profitable secondary resources. System innovation, life cycle thinking and participative backcasting method have allowed to deeply analyse the current system, orientate the problem and explore sustainable solutions through a broad stakeholder participation. A material flow analysis, accompanied by a barrier analysis, has supported the identification of the gaps between the present situation and the 2030 scenario. Eco-design for and from recycling (and a mass _based recycling rate (based on the effective amount of plastic wastes turned into secondary plastics), valorized by a value_based indicator, are the key-points of the action plan.

Повний текст джерелаАнотація:
Plusieurs catégories de MEMS nécessitent un environnement sous vide pour fonctionner de manière optimale, tel le micro-bolomètre. Le fonctionnement optimal de ce détecteur, à la base des imageurs infrarouge non refroidis, nécessite qu’il soit thermiquement isolé, et donc qu’il évolue dans une atmosphère raréfiée (< 10-2 mbar). Le maintien sous vide d’une matrice bolométrique durant la durée de vie d'une dizaine d’années du composant est réalisé par une encapsulation dans un boîtier de très faible volume (de 0,5 à 30 µL).Cette encapsulation sous vide fait appel à deux techniques complémentaires : le scellement hermétique sous vide et l’intégration d’un dispositif d’absorption du gaz dans la cavité, appelé getter. La technique de scellement donnant un joint de scellement suffisamment hermétique (<10-14 atm.cm3.s-1) est la soudure métallique. Le getter est un film mince métallique à base de métaux de transition. Il acquiert une activité de sorption lorsqu’il est chauffé.Les procédés d’encapsulation sous vide de l’état de l’art permettent l’encapsulation de micro-bolomètres à des températures de 300°C. Mais il est fort probable que les futurs matériaux micro-bolométriques en cours de développement ne supporteront pas des températures de recuit supérieures à 280°C. Leur encapsulation demande donc la mise à disposition d’un nouveau procédé de scellement sous vide à plus basse température et d’un nouveau film getter s’activant aussi à basse température.Ces deux techniques ont par conséquent été développées, au moyen de caractérisations en laboratoire et de tests sur composants industrielsSome kinds of MEMS like micro-bolometers require vacuum to operate optimally. This IR sensor is the cornerstone for uncooled infrared detection. Its best sensing capacity is achieved by thermal insulation, which is realized by placing it under vacuum (< 10-2 mbar). The vacuum is maintained throughout the camera lifetime thanks to a microvolume packaging (0.5 to 30 µL).The MEMS vacuum packaging implies the combination of two complementary technical solutions: first hermetic sealing, then getter device integration absorbing internal gas. The sealing technique retained (which enables leak rate <10-14 atm.cm3.s-1) is the metallic bonding. The getter is a thin transition metal film. When activated by an annealing, its surface traps gaseous molecules. The sorption process of the getter is ideally activated during the sealing process of the bonding.The typical temperature packaging process for micro-bolometers is 300°C. It is expected that sensibility of new types of micro-bolometers materials will be degraded if they are exposed to temperatures higher than 280°C. Consequently, their encapsulation require the elaboration of a new low temperature packaging technology.Such a technology has been developed based on experimental studies in laboratory and tests under industrial conditions

Ces travaux portent sur l’étude du transfert de l’arôme viennoiserie encapsulé dans une matrice constituée du mélange gomme acacia – maltodextrines et incorporé dans une génoise emballée (plastiques et papier), dans des conditions contrôlées de stockage (humidité relative et température). Le procédé d’encapsulation utilisé dans cette étude est la lyophilisation. Les propriétés physicochimiques des molécules volatiles influencent leur rétention. Ainsi, les molécules hydrophobes à haut poids moléculaire sont mieux conservées dans ce système. L’incorporation de capsules d’arômes dans les génoises influence leurs propriétés physiques (la couleur et la texture) et favorise la formation d’une croûte pouvant jouer un rôle barrière sur les transferts d’arômes. Au cours du stockage des génoises emballées, l’apport positif de l’encapsulation sur la rétention des arômes a été révélé. Le type d’emballage peut influencer la perte en composés d’arôme dans l’espace de tête génoise – emballage. Ainsi, les emballages plastiques offrent une meilleure conservation des molécules volatiles par rapport aux papiers traitésThis study deals with transfer of viennoiserie aroma encapsulated in a acacia gum - maltodextrines matrix and incorporated in a packaged sponge cake (plastic and treated-paper), under controlled storage conditions (temperature and relative humidity). The process of encapsulation used in this work is freeze-drying. The physicochemical properties of the volatiles molecules influence their retention in the matrix. Thus, the hydrophobic molecules with high molecular weight are more retained. The incorporation of capsules in the sponge cake matrix influences the physical properties of food matrix (color and texture) and supports the formation of a crust which acts as a barrier in the flavour transfer. It was noted that encapsulation contributed in retaining flavour compounds during the storage of packaged sponge cake. Also, the type of packaging can influence the loss of flavour in the headspace between sponge cake and packaging. Indeed, plastic packaging offers a better conservation of volatiles molecules compared to treated-papers

Il presente elaborato si pone l’obiettivo di presentare un sistema che sia capace di garantire la sicurezza alimentare delle capsule monodose per bevande tipo espresso prodotte nel reparto stampaggio di Aroma System Srl.
La soluzione proposta è quella di applicare la procedura l’HACCP ovvero l’Hazard Analysis and Critica Control Point, accompagnata da un adeguato piano di manutenzione.
In particolare nel primo capitolo viene fornita una panoramica generale sul concetto di qualità nel sistema di produzione.
Da qui si è passati poi a descrivere il concetto di analisi del rischio, definendo prima di tutto cosa è un elemento di rischio, e cosa lo distingue da un elemento di pericolo.
Si procede quindi con la definizione di sicurezza alimentare. . Ci si sposta poi al caso particolare del packaging alimentare e della politica di gestione della contaminazione anche in questo ambito.Nel secondo capitolo viene descritta nel dettaglio la politica di HACCP vera e propria.
Lo studio permette una migliore comprensione della procedura HACCP, nel capitolo quattro, mostrandone l’applicazione al reparto di stampaggio di capsule monodose per bevande tipo espresso, dell’azienda bolognese Aroma System Srl.
Nel capitolo quattro viene poi presentato il piano di manutenzione portato avanti da Aroma System Srl sempre nello stesso reparto. L’obiettivo è quello di dimostrare come un buon piano HACCP correttamente applicato al reparto sia inutile senza un adeguato programma di manutenzione che permette alla macchina di lavorare nelle migliori condizioni possibili.

Afin de protéger les denrées alimentaires, l’industrie d’emballage enduit sur un film une couche très fine de polymère pour augmenter ses propriétés barrière aux gaz. Le problème majeur de ces enduits, généralement faits de poly (chlorure de vinylidène), vient de leur production de gaz toxiques à l’incinération. Les restrictions environnementales mondiales évoluent rapidement et sont de plus en plus strictes. De ce fait, des bioplastiques sont envisagés comme alternative. Dans ce contexte, l’objectif de la présente thèse est d'étudier le revêtement de films poly(téréphtalate d’éthylène) avec un polysaccharide, le chitosane. Ce dernier possède de bonnes propriétés barrières au gaz à sec. Cependant, son application dans l’emballage est limitée à cause de son caractère hydrophile. Le but de notre étude est donc d'améliorer les propriétés barrières à sec du chitosane par l’ajout de nano-charges d’argile et sa résistance à l’humidité par greffage de l’acide palmitique à la chaine du chitosane. L'efficacité d'incorporation de la vermiculite a été confirmée par DLS, DVS et DRX. Un facteur d'amélioration de la barrière (BiF) d’environ 100 pour l'hélium et de plus de 10 pour le dioxygène avec l'addition de 50% de vermiculite a été obtenu à sec. Le greffage de l’acide palmitique a été confirmé par spectroscopie IR-TF, ATG, DSC et RMN. Les résultats de mesures de la perméabilité hélium montrent une amélioration de facteur de la barrière (BIF) de 2 d’une couche de chitosane-g-acide palmitique et vermiculite à 60% en poids par rapport au PET non revêtu à 98% HRIn order to protect food, the packaging industry performs a film coating with a very thin polymer layer to increase its gas barrier properties. The major problem of these coatings is that they are generally made of poly(vinylidene chloride) which leads to a toxic gas production during incineration. In view of the rapid change of the global environmental restrictions that become quite stringent, bioplastics seem promising alternatives. In this context, this thesis deals with a fundamental study of poly(ethylene terephthalate) films coated with a polysaccharide: chitosan. Chitosan offers good barrier properties in dry conditions. However, its application in the packaging is limited because of its hydrophilic character. Therefore, the main goal of our work is on one hand to enhance the dry barrier properties of the material through adding nanoclays and on the other hand to improve its resistance to moisture by incorporating palmitic acid by grafting it to the chitosane backbone. The incorporation efficiency of vermiculite was confirmed by DLS, DVS and XRD. A barrier improvement factor (BiF) of about 100 for helium and more than 10 for dioxygen with the addition of 50% vermiculite was obtained under dry conditions. The grafting of palmitic acid has been confirmed by FTIR spectroscopy, ATG, DSC and RMN. The results of helium permeability measurements showed an improvement of the barrier factor (BIF) of 2 in the case of a chitosan-grafted-palmitic acid layer with 60 weight% of vermiculite compared to the uncoated PET at 98% RH

Facing the stress of globalized international market, inflationary pulp commodity, and domestic consuming power in recession, packaging and printing industries are in such predicaments of saturated market demands and oversupply. Moreover, most suppliers offer OEM service instead of product development and innovation that causes price competition in vicious circle. Nevertheless, the market would not be immutable. It is an important topic that all corporates need to think over how to remain corporate profits in a rapidly changing open market. The study explores how packaging and printing industries should clarify their own core competitiveness to capture business opportunities and maintain corporate profits. The study employed semi-structured interviews for data collection and conduct SWOT analysis to understand A-company’s strength, weakness, opportunities, and threats, and propose strategies of aggression, protection and reinforcement via cross analysis. Furthermore, the buyer utility matrix was also employed as the basis to evaluate the management of service model and improve the competitiveness of the case company in future. The study found after investigation as well as analysis, the case company as the second mover has her own unique profiting model. However, the profiting model is not sufficient against the threats from externals while facing various environment. Therefore, a new service model should be considered and applied that combines with marketing, design, cultural and creative soft powers to achieve the goals of sustainable development and profitability.

This study centres on curriculum development for a master craftsman level in the Printing, Newspaper and
Packaging Industries which is didactically sound and takes cognisance of the dynamic vocational education
and training milieu in which it occurs. Curriculum and curriculum development is viewed from a systems
perspective and incorporates the specific andragogic didactic needs of the learner target group as well as
the unique needs of an industrial sector.
Because the National Qualification Framework model advocates an outcomes-based approach to
curriculum development this necessitated the identification of a suitable standards generating process to
articulate the master craftsman unit standards into a qualification capable of being recognised by the
National Qualification Framework. The nature and complexity of the underpinning knowledge, skills and
competencies for the master craftsman level were quantified and qualified by means of skills and
competency profiling and the development of a job outcome taxonomy of skills, knowledge and attributes
which incorporated critical cross field and fundamental skills, and their underpinning knowledge
requirements.
Using aspects ofvarious vocational education and training models and empirical research course content
was sourced, evaluated and developed into appropriate modules of learning that are congruent with the
accepted competency based modular training system used in the Industries. Course maps that integrate
theory and practice were developed with multi skilling milestones linked to learner certification.
Evaluation of resources for the delivery of the Master Craftsman Programme was facilitated by means of
a provider quality assessment and accreditation system. The interactive teaching-learning situation and the
evaluation processes and procedures were developed to enhance the assessment of applied competencies
in the world of work. A pilot study and unit standards generating activities are to be used as a means of
implementing and institutionalising the master craftsman curriculum.
The findings of this study revealed that by viewing the curriculum from a systems perspective and using a
suitable curriculum development model a creative master craftsman curriculum development process could
take place. The competency profiling technique and taxonomy of competencies, skills, knowledge and
attributes enabled the curriculum process to be a top-down approach which is outcomes-based.Didactics
