The pulp may be formed from a fibrous raw material. The wetting agent may include a functional additive such as a sol. A sol may include a solvent, an alkoxide, and optionally a catalyst. The air-laid pulp, intermediate pulp, and/or moulded product may be free or substantially free of thermoplastic polymers and/or hydrocarbon-based plastics. The moulded product may be a fibre-based bubble wrap. The fibre-based bubble wrap may be formed from reel-to-reel processes.
