Kraft paper is a packaging material that gets its name from the Kraft pulping process, pioneered by Carl F. Dahl of Germany in the 1880s.

Normally, in the manufacture of paper, wood is ‘pulped’ (ground to a pulp) first, but Dahl found that treating the cellulose pulp with certain chemicals (sulfates) increased the strength of the paper. He called his paper Kraft paper – Kraft in German means ‘strength’.

What is sustainable packaging?

Sustainable packaging is the development and use of packaging that can improve sustainability. This involves increasing the use of life cycle inventory (LCI) and life cycle assessment (LCA) to help guide the use of packaging, thereby reducing environmental impact and ecological footprint. It includes the entire supply chain: from basic functions to marketing, to retirement (LCA) and rebirth. In addition, the ecological cost-to-value ratio may be a useful goal to improve the long-term viability and quality of life of humans and the longevity of natural ecosystems. Sustainable packaging must meet current functional and economic needs without affecting the ability of future generations to meet their needs. Sustainability is not necessarily the end state, but a continuous improvement process.

Companies implementing these environmental initiatives are reducing their carbon footprint, using more recycled materials, and reusing more packaging components. They often encourage suppliers, contract packers, and distributors to do the same.
