FILM-CLOSURE APPARATUS FOR PLASTIC FILM MATERIAL, PRINTED CIRCUIT BOARD, AND METHOD OF ENHANCING THE OPERATION OF A FILM-CLOSURE APPARATUS

摘要

A film-closure apparatus (10) is provided which is suitable for closing plastic film material using heat. The apparatus (10) comprises a guide path (14) along which at least part of a plastics film material can pass; a drive means for moving the film material along the guide path (14); and a printed circuit board (30) comprising a circuit substrate having first and second major board surfaces and a perimeter edge surface, and an electrically conductive heating element which is provided on the circuit substrate along at least part of the perimeter edge surface. The electrically conductive heating element is positionable on the guide path (14) to apply heat to the film material thereon.
