1. Influence of Ionizing Radiation on Biodegradable Foam Trays for Food Packaging Obtained from Irradiated Cassava Starch
ABSTRACT Biodegradable polymers, such as starch, cellulose, and derivatives thereof, are being studied to produce innovative packaging in the most diverse shapes (films, bags, trays, bottles, etc.) to attend this current market trend. The aim of this work was to produce foam trays from cassava starch for food packaging via extrusion followed by thermoforming

3. Desempenho de filmes multicamadas em embalagens termoformadas
Filmes plásticos flexíveis multicamadas podem ser utilizados como embalagens termoformadas de produtos alimentícios à base de carne, sendo que para esta aplicação, necessitam apresentar especificações técnicas de média ou alta barreira ao oxigênio, dependendo das características do produto a ser embalado, de forma a evitar sua contaminação e ri

4. Sensor piezelétrico baseado na tecnologia dos eletretos termo-formados: aprimoramentos dos processos de produção / Piezoelectric sensor based on electrets thermoforming technology: improvements on the production processes
This work describes two improvements on the production of piezoelectric sensors, which are based on thermo-formed electrets technology. These sensors which were previously prepared by fusing and molding two Teflon FEP films into bubbles structures in a hot-press system, presented piezoelectric coefficients over 300 pC/N after properly electrical charging. Ho

6. Evaluation comparison of PMMA intermolecular interaction in thermoforming. / Avaliação comparativa da interação intermolecular do PMMA em termoformagem.
Poly(methyl methacrylate) sheets can be modified adding a cross-linking agent and a plasticizer, to increase performance during thermoforming. The intermolecular interaction modification can be achieved adding different amount of cross-linking agent (TEGDMA) and a plasticizer (DOP). They have an effect on the network polymer system improving the intermolecul

7. Chip-based Three-dimensional Cell Culture in Perfused Micro-bioreactors
We have developed a chip-based cell culture system for the three-dimensional cultivation of cells. The chip is typically manufactured from non-biodegradable polymers, e.g., polycarbonate or polymethyl methacrylate by micro injection molding, micro hot embossing or micro thermoforming. But, it can also be manufactured from bio-degradable polymers. Its overall
