Supplementary part for a bag and method for fastening supplementary part to a bag

Abstract

Disclosed is a supplementary part for a bag that can be fastened in connection with an opening formed in the wall of the bag, including: a base element with a planar raised central portion and a rim plane surrounding the central portion. The plane passing through the rim plane is lower than the central portion so the central portion can be mounted at the opening. The inner surface of the wall around the edge of the opening is supported against the rim plane. The outer surface of the central portion has a visible UV printing layer. A fastening frame corresponds to the rim plane and is mountable around the raised central portion on top of the rim plane. The base element of the supplementary part and the fastening frame can be fastened to each other. Also disclosed is a method for fastening the supplementary part for a bag.
