Consumers are becoming increasingly aware of the impact of some products on the planet and are making purchasing choices based on sustainability factors. Producing packaging for liquid laundry detergent, shampoo and conditioner without additional layers of plastic is a major challenge. Unilever has now announced the launch of a paper-based laundry detergent bottle. A prototype has been developed for the laundry brand OMO (also known as Persil, Skip and Breeze) and is set to debut in Brazil in early 2022. The company is aiming to introduce the bottle in Europe and other countries soon after.

The technology has been developed in partnership with the Pulpex consortium, a collaboration between Unilever, Diageo, Pilot Lite and other industry members. The bottles are made of sustainably sourced pulp and designed to be recycled in the paper waste stream. They are sprayed inside with a proprietary coating that repels water, enabling the material to hold liquid products that contain surfactants, fragrances and other active ingredients. Richard Slater, Unilever Chief R&D Officer, said: “To tackle plastic waste, we need to completely rethink how we design and package products. This requires a drastic change that can only be achieved through industry-wide collaboration. Pulpex paper-based bottle technology is an exciting step in the right direction, and we are delighted to be working together to trial this innovation for our products.”
