Tetra Pak is a multinational food packaging and processing company of Swedish origin with head offices in Lund, Sweden, and Lausanne, Switzerland. The company offers packaging solutions, filling machines and processing solutions for dairy, beverages, cheese, ice-cream and prepared food, including distribution tools like accumulators, cap applicators, conveyors, crate packers, film wrappers, line controllers and straw applicators.Tetra Pak was founded by Ruben Rausing and built on Erik Wallenberg's innovation, a tetrahedron-shaped plastic-coated paper carton, from which the company name was derived. In the 1960s and 1970s the development of the Tetra Brik package and the aseptic packaging technology made possible a cold chain supply, substantially facilitating distribution and storage. From the beginning of the 1950s to the mid-1990s the company was headed by the two sons of Ruben Rausing, Hans and Gad, who took the company from a family business of six employees, in 1954, to a multinational corporation. Tetra Pak is currently the largest food packaging company in the world by sales, operating in more than 170 countries and with over 23,000 employees . The company is privately owned by the family of Gad Rausing through the Swiss-based holding company Tetra Laval, which also includes the dairy farming equipment producer DeLaval and the PET bottle manufacturer Sidel. In November 2011, the Tetra Brik carton package was represented at the exhibition Hidden Heroes – The Genius of Everyday Things at the London Science Museum/Vitra Design Museum, celebrating "the miniature marvels we couldn’t live without". The aseptic packaging technology has been called the most important food packaging innovation of the 20th Century by the Institute of Food Technologists and the Royal Swedish Academy of Engineering Sciences called the Tetra Pak packaging system one of Sweden’s most successful inventions of all time.

The aims of InnHF project are to offer a multidisciplinary training in the field of risk assessment and maintenance management integrated with human factors, in tight contact with companies and universities within this consortium; to strengthen and structure initial training of researchers in system engineering at European level; to attract students to scientific careers; to provide trained researchers with the necessary skills to work in industry; and to improve career perspectives by broad skills development. The INNHF scientific main objective is thus to formalize an approach and make it possible to integrate the current and developing assessment methods recommended or required by recognized industrial standards and methodologies, with an easy to use but complete human factors and system health management approach, the following goals will be achieved: 1) Review of the applicability of most recent generation standards that are not yet fully acquired by different industries and verification of their effectiveness in safety assessment. 2) Devising a method to account qualitatively and quantitatively for the human factor in the wider applied risk assessment methodologies. Verifying how a proper account of the impact of human and organizational factors (H&OF) in the operational phase may provide a sensitive change in the results of the assessments. 3) Reviewing the methods to account qualitatively and quantitatively for maintenance effectiveness, taking also into account HOFs, verifying how a proper account of the maintenance strategy may provide a sensitive change in the results of the assessments. 4) To translate the results of the analysis performed through the novel approach in a factual design improvement initiative for new or existing plant or machinery able to provide leverage for competitive advantage (maximum availability, minimum unscheduled shutdowns of production, economic maintenance, minimum incident incident and accident).

In this Monte Carlo simulation study we use mesoscopic modeling to show that β-casein, an unstructured milk protein, adsorbs to surfaces not only due to direct electrostatic and hydrophobic interactions but also due to structural rearrangement and charge regulation due to proton uptake and release. β-casein acts as an amphiphilic chameleon, changing properties according to the chemical environment, and binding is observed to both positively and negatively charged surfaces. The binding mechanisms, however, are fundamentally different. A detailed, per-residue-level analysis shows that the adsorption process is controlled by a few very specific regions of the protein and that these change dramatically with pH. Caseins, being the most abundant proteins in milk, are crucial for the properties of fermented dairy products, such as nutrition, texture, and viscosity, but may also influence adhesion to packaging materials. The latter leads to product losses of about 10%, leading to economical and environmental problems. © 2012 American Chemical Society. Source

The development of mechatronic systems involves the use of multiple disciplines, from mechanical engineering to electronics engineering and computer science. Traditionally, every discipline was developed independently and then integrated to generate the final system. However, high-quality designs cannot be achieved without simultaneously considering all the engineering disciplines. This integrated approach carries an intrinsic complexity into system design process and numerous researches are on-going in order to find out optimal methods. This article illustrates a methodology based on Model-Based System Engineering to support the integrated development of complex mechatronic devices. The main contribution is the introduction of a design methodology based on the W model and the identification of SysML as the tool to support the whole process. This method will also address the problem of "devices interchangeability", that means the possibility to develop the functionality of a system with different operation principles, at a very early stage of the development process (i.e. during the conceptual development). To achieve this goal, the methodology treats the problem of linking the conceptual with executable models to enable the validation by simulation. Main advantages of this methodology are in providing, to the mechatronic systems designers, a fixed schedule which does not limit their intuition and reduces complexity through a hierarchical approach. The process has been tested through the rationalization of the choices that have brought to the current solution of the filling system of an automatic filling machine for liquid foodstuff. Source

Systems Engineers experience recurrent decisions on the same Technical Performance Measures, TPMs, during the overall systems life-cycle. The availability of a coherent decision framework allows identifying, implementing and evaluating effectiveness of the resulting Verification Validation and Testing strategy. It supports continuous improvement of the system and sustainable human factors integration. This paper proposes an application of Multi Domain Matrices in order to model the key aspects of repetitive decisions on the same TPM during the system life-time. It highlights how to manage evaluation, a coherent and effective decision process. The prior and quantitative evidences are updated by new evidences into the posterior and qualitative ones. The advantages and the cons of the selected approach in terms of representation, knowledge increase, sharing and evaluation are discussed. Source

Paperboard is a widely used material in industrial processes, in particular for packaging purposes. Packages are obtained through a forming process, in which a flat laminated sheet is converted into the final 3-D solid. In the package forming process, it is common practice to score the paperboard laminate with crease lines, in order to obtain folds with sharp edges and to minimize the initiation and propagation of flaws during the subsequent folding procedures. In this work, a constitutive model for the mechanical response of crease lines is proposed and validated on the basis of experimental tests available in the literature. The model has been implemented in an interface finite element to be placed between adjacent shell elements and is intended for large-scale computations of package forming processes. For this reason, the material model has been developed at the macroscopic scale in terms of generalized variables, aiming at computational effectiveness. © 2011 Elsevier Ltd. All rights reserved.
