Definitions

• the invention relates to a vacuum cleaner filter bag with a bag wall comprising a first side wall and a second side wall, wherein on the first side wall, a holding plate is arranged.
• Vacuum cleaner filter bags are today mainly made of nonwovens. Due to their excellent dust retention capabilities, vacuum cleaner filter bags made of nonwovens have virtually supplanted paper filter bags.
• the production of filter bags made of nonwovens is fundamentally different from the production of paper bags. Common are rectangular flat bags, which are formed from an upper and a lower side wall, which are circumferentially welded together at the edge.
