Plastic packaging, as an indispensable element of modern life, has facilitated the smooth flow of goods. However, with the intensification of the global environmental crisis, the long-term erosion of the natural environment by plastic waste, including soil degradation, water pollution, and the disruption of the ecological chain due to marine life ingesting plastic, has become an environmental issue that urgently requires a global response.

Against this backdrop, the concept of circular economy has emerged, with its core principle of the 3R-reduce, reuse, and recycle-guiding the direction of environmental protection and sustainable development. Among these, reduction is placed at the forefront, emphasizing the reduction of resource consumption and waste generation at the source.

The development and application of eco-friendly packaging materials are key measures in implementing this concept. Biodegradable honeycomb paper packaging materials, as a formidable competitor to plastic packaging, are gradually gaining prominence and widespread recognition. Their unique honeycomb structure design not only endows the material with excellent compressive strength and cushioning performance but also enables rapid degradation in natural environments, significantly reducing environmental burden.
