Abstract
Description
図2は、本発明の現在の好ましい実施形態を示す。第1及び第2の包装材料積層品10、12が、シールジョー14及びアンビル16によって、ジョイントで共に封止される。図のジョイントでは、2つの積層品が、それらの内側表面が互いに面した状態で互いに当接している。この現在の好ましい実施形態では、シールジョー14は、(積層品が、熱を生成するアルミ箔を備える)誘導封止に使用されるものと同様のインダクタである。ここでは、インダクタ14は、交流電源18に結合される。交流は、好ましくは75〜300Aの範囲内にあり、電源から必要とされる電力は、数kWである。好ましい間隔は、2〜10kWである。周波数は、好ましくはMHz範囲にあり、好ましい周波数間隔は、0.5〜5MHzである。最も好ましい間隔は、1〜4MHzである。当局の規制により一般使用について禁止される周波数は、当然ながら、実際には前記間隔から除外される。
