In order to reduce production costs, during the processing of aluminum-plastic films in the packaging field, glue is generally applied to the side of the plastic film and then extruded and bonded with aluminum foil. In order to avoid excessive glue coating, which may cause glue to overflow from the side of the composite film during extrusion, glue is not applied to the edge of the plastic film during the initial processing. Therefore, after the composite is completed, the unbonded edge area after the composite needs to be cut to remove the unbonded part to obtain a film with the plastic film and aluminum foil completely adhered, and then the subsequent processing steps are carried out.
