In this research, three alternative approaches to chemical preservatives to extend the mold free shelf-life and quality of pita bread were investigated namely: Modified Atmosphere Packaging (MAP) involving gas packaging, oxygen absorbents technology and ethanol vapor generators, high pressures, and direct and indirect heating. / Gas packaging using 60%CO2 (balance N2) inhibited the growth of Aspergillus niger and Penicillium notatum from 3d (pita bread packaged in air) to 35d at ambient temperature. A longer extension in shelf-life (42d) was possible using an Ageless oxygen absorbent or a Freshmax oxygen absorbent label in conjunction with gas packaging. / Similar results were obtained with 2G--4G sachets of Ethicap, and 100--200S sachets of Negamold, a dual functional oxygen absorbent-ethanol vapor generator. / High pressures (30--400MPa) used to inhibit mold growth, resulted in delamination of the packaging film and textural changes to the pita bread. / Other alternatives, such as direct heating and microwave processing had a minimal effect in increasing the shelf-life of pita bread.

The increased use of returnable packaging have given rise to the trend of packaging logistics.The operation of returnable packaging is challenging for global companies due to thecomplexity in the process and information flows. Companies invest in returnable packagingsystems in order to ensure quality throughout the supply chain. Despite the large investments inan returnable packaging fleet, it is often poorly controlled, leading to vast tied-up capital andshrinkage.This thesis proposes how the visibility and control of the system is affected by thecategorization of packaging and the allocation of responsibilities throughout the packaginghandling process. Theoretical and empirical studies were carried out, the theoretical part helpeddefine the problem. A case study were performed at Scania CV AB in Södertälje, Sweden.Results of this study shows that categorization of packaging is not sufficient to attain a suitablelevel of control in an packaging handling process. Although it could be used as a supporting orgoverning documents for standardization in the process. Findings showed that theresponsibilities in the process should be centralized in as large extent as possible. Although ifthe current process is lacking visibility and control, the benefits of centralized control may belost.

People of the modern world consume more than they ever used to do. Because of the close correlation between consumption and the amount of waste, the waste volume is also expected to increase. The purpose of this study is to examine if some measures in the recycling process from Sweden could be implemented in Indonesia. In fact, Indonesia is one of the countries in which the waste management system is struggling. Tetra Pak, one of the world leading producer of food packaging, is studied in this report. Tetra Paks recycling rate of their beverage cartons is relatively low, 8.42 %, in Indonesia compared with their recycling rate in other countries. To answer the purpose, information was collected from scientific reports, by interviews carried out in both Sweden and Indonesia and by study visits in Indonesia. The results of the study shows that there are measures which could be made in the recycling process to increase the recycling rate in Indonesia. School projects and deposit systems could increase the collection rate and a drumscreen and a buffertank could make the recycling process more profitable for the papermills. There is also some alternative end products which could make the whole recycling process more public visible. One of the conclusions of this study is that the paper mills should adjust their drumscreens, this to increase the fibre yield which is crucial for the recycling value. Another conclusions is that Tetra Pak should consider to initiate a recycling business by their own, in order to reduce the burden on the environment.

Time and expense has been spent on developing the functional aspects of packaging to ensure food safety, while providing innovations such as plastic trays that can go in the oven, microwave and freezer. Now, consumers are being faced with increasing changes in the way that their favourite products look on the shelf, as companies undertake sometimes large operations to update packaging. The beverage industry is one among the front-liners where massive investments are being made for expansion and technological upgradation. The packaging of beverages both carbonated and non-carbonated, is a complex technological branch in the Food Processing /Packaging industry. The traditional returnable glass bottle has given way to newer plastic containers as well as cartons. The current trend is to improve the conventional containers, extend their share in the large market, extend the shelf-life of the products, provide greater consumer convenience and ultimately to produce economic packages. Due to increasing self-service and changing consumers’ lifestyle the interest in package as a tool of sales promotion and stimulator of impulsive buying behaviour is growing increasingly. So package performs an important role in marketing communications, especially in the point of sale and could be treated as one of the most important factors influencing consumer’s purchase decision. Literature analysis on question under investigation has shown that there is no agreement on classification of package elements as well as on research methods of package impact on consumer’s purchase decision. This dissertation reports on an investigation into the role of packaging and how it influences the consumer when buying their choice of beverages. The study was limited to University of KwaZulu-Natal students. Taking into consideration that package could be treated as a set of various elements communicating different messages to a consumer; the research model was developed and tested in order to reveal impact of visual and verbal package elements on consumer’s purchase decisions. Five research questions were developed to address the objectives and the aim of the study. The study concluded that the packaging plays a big role in attracting the consumer’s attention and influencing them when buying their choice of beverages. / Thesis (MBA)-University of KwaZulu-Natal, Durban, 2012.
