24 Mar 2020 --- Arvid Nilsson, supplier of fastening elements to the construction industry, and packaging material provider BillerudKorsnäs have joined forces to deliver a plastic waste-reducing, water-resistant “eco-box” for nuts, bolts and screws. Made of 100 percent primary Nordic wood fiber, the thick, durable carton box caters to the weather-specific, high-demand needs of construction workers on site. BillerudKorsnäs affirms the box can be left in the rain “for weeks” without compensating on sturdiness or compression strength.
