This ground-breaking technology has been developed in partnership with the Pulpex consortium, a collaboration between Unilever, Diageo, Pilot Lite and other industry members. Unilever has been able to use the technology to package liquid products in first-of-its-kind paper-based bottles, made of sustainably sourced pulp and designed to be recycled in the paper waste stream.
The bottles are sprayed inside with a proprietary coating that repels water, enabling the paper-based packaging material to hold liquid products like laundry detergent, shampoo and conditioners, which contain surfactants, fragrances and other active ingredients.
Creating recyclable, paper-based packaging without additional plastic layers is a huge challenge. Pulpex’s patented pulp packaging provides a promising solution to radically reduce the use of plastic and will help Unilever achieve its commitments to a waste-free world.
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.
“Innovating with alternative materials is a key part of our sustainable packaging strategy and will play an important role in our commitment to halve our use of virgin plastic materials by 2025.”
Consumers are becoming increasingly aware of the impact of products on the planet and are making purchasing choices based on sustainability factors, including packaging. Delivering functionally superior products that address environmental issues that people care about, such as the innovative sustainable packaging announced today, will make Unilever a stronger, more successful business.
