Definitions

  • the invention relates to a device for producing packaging material from paper.

  • bubble wrap made of polyethylene for example, is technically recyclable, recycling is in practice relatively complex and therefore expensive. As a result, bubble wrap is often disposed of after a single use. Since bubble wrap is made of polyethylene, for example, is not biodegradable, this leads to substantial environmental pollution.

If the plastic does not decompose, it pollutes ecosystems and poses a threat to marine animals, for example. If the plastic is shredded or decomposed over time, for example due to mechanical influences and UV radiation, plastic particles are created, particularly in the form of microplastics, which remain in the environment or are ingested by living organisms through food.
