With the Newlong 500H series, flat paper tape is folded sequentially in one direction to make the 8-folded flat paper strap-handle. This handle is then pasted inside the bag along with the paper patch. This inward folding of the handle concealed in the bag as standard, allows the finished bags to easily handle. Handle unconcealed type device is option.  Optional model number-HS (i.e. 508HS etc.) is specified by machine with servo-motors.
