FIELD: process engineering.
SUBSTANCE: inductive heat sealing device 15 fed in first direction comprises inductors 20, 21 to interact with packing material by, at least, one active surface 25, 26. Note here that shell 24 is made from heat conductive material and comprises inductors 20, 21 and insert 30 made of magnetic material to concentrate flux and arranged in said shell 24. Sealing device incorporates also element 23 made of plastic and including, at least, first part 19 arranged in first direction A between shell 24 and insert 20 so that it is surrounded, at least partially, by shell 24.
EFFECT: ruled out fractures in shell.
