Lego will start replacing plastic packaging with paper bags from 2021 as the toy brick maker aims to become more sustainable.
Lego said it had been prompted by letters from children asking it to remove the single-use plastic bags.
It said it would be investing up to $400m (£310m) over three years to improve its sustainability efforts.
Lego bricks themselves are made of plastic, although the company is exploring alternative materials.
“We have received many letters from children about the environment asking us to remove single-use plastic packaging,” Lego Group chief executive Niels B Christiansen said.
“We have been exploring alternatives for some time and the passion and ideas from children inspired us to begin to make the change,” he added.
From next year the toy company will start introducing recyclable paper bags, certified by the Forest Stewardship Council, to package its loose bricks.
