Destech publications, inc. Announces the publication of heat sealing technology and engineering principles and packaging applications. Written by dr. Kazuo hishinuma, who is currently chief executive of hishinuma consulting in kawasaki, japan, this book is the first to cover all phases of heat sealing as it relates to packaging. Beginning with the basics of heat sealing processes and thermoplastic materials, the book explains, with numerous formulas and new experimental data, all the key parameters. With this information, the author then presents new ways to improve the reliability of heat sealingand the quality of heatsealed packaging. Novel monitoring techniques are provided that enable packaging engineers to better control parameters that lead to more reliable seals in different types of packaging and with different materials, including laminates. Specifically, the author shows how important it is to have accurate measurement of the melting surface. The book presents monitoring techniques for carrying out such measurements and demonstrates how they lead to better heat seal process control and quality. These techniques, along with novel ways of using the peel seal and tear seal, are explained in practical terms, to assist engineers to troubleshoot and eliminate problems encountered in heat sealing, e.g., overheating, polyball, and packaging failure. Hundreds of illustrations and numerous case studies support the practical information in this book. The technical data found in this resource is a necessary supplement to jis and astm standards. Main sections history and function of heat sealing technology the chemistry of heat sealing the fundamentals of heating for heat sealing fundamentals of heat sealing operation factors in heat sealing failure making the conventional heat sealing method more efficient experimental technique for inspecting peel seal and tear seal methods for confirmation and improvement of heat sealing functions functional improvements to the heat sealing process case studies of analysis and improvement of heat sealing failure heat seal test method that complements the jis standard method and uses the melting surface temperature as a parameter
