加熱速さがヒートシールの発現パラメータ（第2報）: 《加熱速さ》の詳細解析と新知見にどう対応するか？

摘要

ヒートシール技法が開発されて以来，半世紀もの間《ヒートシール強さ?の発現は《加熱温度?によって一元的に決定されるとされてきた。付随的に《加熱時間?　と　《庄着庄?が比例的に作用するとしてきた。2000年に［ASTM F2029］が制定され，《加熱温度?を［加熱体温度＝加熱体調節温度］と定義されるまで，加熱温度はどのような温度であるか曖昧にされてきた。%Heat sealing technology as well as plastic has been a main packaging technology for more than half a century. It has long been thought that heat sealing strength highly depends on how we control "heating temperature". However, as a result of years of my research, it was found that "heating speed" is more related to expression of heating strength, and the outline of its mechanism was disclosed to the public last year.rnAs a result of my examination of the details of heat sealing strength phenomenon governed by "heating speed", an expression of "heat sealing strength" was confirmed as a dynamic "3D phenomenon" of "heating temperature" and "heating duration". If this finding is viewed as an ultimate phenomenon of heat sealing, we can overcome the vulnerability of the heat sealing strength in traverse direction, which has been pointed out for a long time. Bringing "heating speed" factor will make it possible to discuss reasonable heat sealing strength and to re-design of packaging materials.rnHere, details about co-relation between "heating speed" and heat sealing technology are reported.
