Fraunhofer Institute Develops Method for Plastic-Free Paper Packaging Researchers at the Fraunhofer Institute have achieved a significant advancement in the development of sustainable packaging solutions as part of the PAPURE project. The Institute has successfully demonstrated a technique to eliminate the need for plastic layers in paper-based packaging. The process involves meticulously gluing and sealing paper bags using a specialized method, incorporating pores and subsequently sealing them with a paper bag constructed without plastic or adhesive. This innovative approach addresses a long-standing challenge within the paper packaging industry. Traditionally, paper packaging relies on plastic layers to maintain product freshness and prevent leaks. The new method focuses on modifying the paper itself, rather than introducing new materials. Initial results are described as promising and surprising, indicating a viable pathway toward completely plastic-free packaging for products like milk packs and crisp bags. The core of the innovation lies in a clever technique that effectively utilizes paper as its own “glue,” eliminating the requirement for external adhesives. This development represents a substantial step forward in creating practical and environmentally friendly packaging options, tackling the persistent issue of plastic use in the paper industry.
