Stunning Tree-Free Gift Bags are made from eco-friendly source materials such as sustainably farmed kenaf, bamboo, sugar cane, hemp, and flax, as well as a high degree of post-consumer recycled paper. Tree-Free has invested heavily in kenaf farming in the US. The kenaf plant grows 12-14 feet in 6 months, making it much more sustainable than trees for paper. Using kenaf instead of trees saves forests, preserves animal habitats, uses less chemicals and conserves energy.
