These are materials that increase the stability of packaging or enable it to fulfil its purpose in the first place.
These may be additional securing devices, the closure, protective measures or measures to ensure the cohesion of the individual packaging materials.
Sealing aids are for example package cord, tape or wrapping tape. Seals, warning labels, banderoles or stickers can be used as package aids for marking or securing. Protective aids are, for example, flame retardants or drying agents. For better protection of the delivery, padding materials such as wood wool, foam, air cushions, corrugated cardboard or polystyrene chips can also be used.
