Detergent Packaging solution by Walki: now even more Sustainable

Detergent Packaging

Walki®Pack D is a solution developed especially for packaging washing powders. “D” stands for detergent. It consists of a strong grey cardboard as the base material, a barrier layer for protection from water vapour and a thin, coated paper for printing and finishing. Conventionally, this type of water vapour barrier is manufactured from petroleum-based polymers. As an innovator and pioneer in the field of sustainability, Walki has also developed an even more sustainable concept called Walki®Wood Pack-D, which uses alternatives made from tall oil for the barrier. Tall oil is a by-product of pulp production. As such, it is obtained from vegetable raw materials, but it does not compete with food production. Tall oil can be used to produce coatings with the same properties and barrier levels as those produced from crude oil.


The tall oil-based barrier protects the product just as effectively against clumping, keeps it dry and free-flowing and responds identically in the course of further processing. “The laminate construction with the alternative barrier layer is exactly the same as the previous one and can be replaced without having to adapt packaging production or filling lines. It consists of 100 percent renewable raw materials and is completely recyclable,” says Stefan Erdmann, Technical Service & Development Manager Barrier Board at Walki. Walki®Wood Pack D can be used to package any type of powdery, hygroscopic product, such as wallpaper paste or tile adhesive.


One step further is a concept that is currently close to market maturity and is expected to be available on an industrial scale from 2020: Walki is a pioneer in the use of certified circular polymers, which allow the material cycle to be closed. This is because they are produced in an innovative process from low-value, mixed plastic household waste that would otherwise be incinerated or landfilled. They are manufactured by SABIC, a long-term Walki partner. “Walki is a pioneer when it comes to sustainability. Today, more than 80 percent of our products are made from renewable or recycled raw materials. Our goal is to increase this to 100 per cent by 2030,” says Leif Frilund, President and CEO Walki Group. “We have already taken an important step with our tall oil based barrier solutions. Another step will be the introduction of products with circular polymers.”
