Better With Less – design challenge winners talk about their innovations

​In Metsä Board’s Better with Less – Design Challenge, innovative solutions for frequently used consumer packages were gathered from entrants around the world. A key focus area in the competition was in creating better experiences for consumers while reducing the environmental impact of the packaging in general.


​Secure transportation without plastic

Streching inner part“Stretching Inner Part” by Iiro Numminen (1st Prize Winner)

“The initial idea came from the triangle form, which is very fascinating to me. With the Better with Less – Design Challenge, I was able to develop my idea further, leading me to use the triangular form as a design element in the inner part of cardboard packaging.” 

This design eliminates the need for bubble wrap completely, as the cardboard design can be extended to secure the product in the packaging. Thanks to a flexible inner part and the lid of the box, the product can’t move around during transport. The inner part can effortlessly be scaled for almost any box size and product thanks to the triangular design.

Playful eco-friendliness for children

“My design is a packaging solution for dried fruit and nuts mainly for children. Its surface has two half-cuts to extract a cardboard puppet, and it’s made by coated cardboard to ensure the food is fresh.” 

After its primary use as a food container, the packaging can be used as a children’s toy. On the packaging, the pictures represent animals eating an almond and a cashew nut, to give kids insight into what animals eat in nature. It’s also resealable and easily recycled. 

Plastic-free toilet paper packaging

“The four of us visited a store and looked for packaging that needed improvement. The first thing we noticed was the big plastic mountain at the toilet paper department. By replacing the plastic packaging with a more ecological material like cardboard, this design helps to reduce plastic in the packaging industry.”

The students created a solution to the traditional toilet paper packaging. Using a cardboard tube, six toilet rolls can be stacked on top of one another. Thanks to the glueless closure and a simple tear strip, the need for plastic is completely removed. 

Less packaging layers, improved recyclability

“Moisture Face Creme Cosmetic Package” by Abdullah Cam and Dennis Lohmann (Honorary Mention)

“Currently, the products in the shops have several layers of packages around the actual product. If we can get rid of at least one of these layers, that would be a nice achievement in our view.”

This design, ideal for the cosmetics industry, takes the solution one step further, making it also easy to recycle the package after the life cycle has ended. With one separate paper element and one plastic element, the recycling of cosmetics packaging is really simplified.

Plastic-free open mechanism for everyday products

Twist“Twist” by Pawel Krawczugo (Honorary Mention)

The concept behind TWIST is to provide a functional packaging solution for the cosmetics as well as other industries, where a simple design can be utilized for a variety of products. The packaging is versatile and can be shaped to pack small cylindrical objects e.g. toothbrushes, mascaras, and eyeliners.
