Buyers of bottled water, mistakenly believing it “greener” and safer than the tap variety, have had a terrible shock recently. Suddenly, the packaging and long-distance transportation of mineral water in plastic or glass has been recognised as environmentally barmy. Journalists reporting the volte-face have also been pointing out that the product is nothing like as pristine as its purveyors cla...

An original packaging method suitable for integrated thermal mass flow sensors is presented. The method consists in the application of a plastic transparent adapter to the chip surface. The adapter is sealed to the chip surface by means of a thermal procedure. By this approach it is possible to selectively convey the fluid flow to reduced chip areas, avoiding contact with the pads. Fabrication ...

solution. Such agents also enhance the stability of certain nylon solutions. All bacteriostatic agents are not effective when dispersed in the plastic matrix. Each specific combination must be tested. Those found to be bacteriostatic may have useful application in surgical dressings for wounds or burns, packaging, or for painting areas which must be kept free of bacterial activity. It is possib...

Epoxidized vegetable oils are the product of vegetable oil epoxidation reactions. Since the epoxidized vegetable oil is a nonpoisonous plasticizer, it has been wildly used in the plastic packaging of food and medicine. Among the various epoxidized vegetable oils, the application of epoxidized soybean oil is broader than others. Nowadays, it’s the third largest category of plasticizers. However,...

A multi-layer plastic packaging technology has been developed for microfluidic systems containing electrical and mechanical functionality. Hot embossing and heat staking of plastics, micro stenciling of electrodes, and stereolithography (SLA) was combined with conventional MEMS fabrication techniques to realize the system. The approach allows for multiple materials of fabrication, provides a so...

Abstract The objective of this study is to investigate the consumer perceptions about quality and safety foods packed in plastic, as well impact plastic materials on human health. To carry out study, a questionnaire survey consumption habits knowledge packaging was conducted sample 487 Portuguese adult citizens. results revealed that most respondents (81%) think food when purchasing foods. Addi...

The encapsulation stress induced on a micromachined silicon membrane pump encapsulated in plastic is quantified. A combination of numerical and analytical techniques are used to deduce limits for the maximum permissible diemensions of a membrane subject to encapsulation stresses. The approach uses finite element techniques to estimate the membrane stress due to packaging followed by an elastic ...

A simple theoretical model was developed to assess the contribution of the pathogens and group D pharmaceutically active waste to the toxicity of the fire plume from an accidental fire in the stored material. The method was applied to stored waste at an authorised incinerator site and the study showed the additional hazard of the pathogen biohazard and pharmaceutically active material to be neg...
