Читать книгу Packaging Technology and Engineering - Dipak Kumar Sarker - Страница 32

In this chapter packaging materials are considered from a chemical engineering perspective, that is, processes involving the building blocks of certain raw materials, such as ores, and methods of extraction and exploitation. The use of rigorous extraction in industrial processes and its influence on material quality and waste production including scrappage (slag and clinker) follows. Processes including wood‐pulp manufacture and ore‐smelting are core contributory stages in the fabrication of modern packaging materials. The description of these processes is accompanied by an outline of the manufacture of glass and its use according to its starting materials. The raw materials are used combinatorially in numerous grades and forms of complex and composite‐type materials.
