The shelf life of sulfur-free paper is not constant but influenced by multiple environmental factors. In-depth understanding of these key factors and their mechanisms is essential for scientifically managing sulfur-free paper inventory and extending its service life. Studies show that temperature fluctuations, humidity changes, and light conditions are the three core elements affecting sulfur-free paper shelf life, accelerating physical performance degradation and chemical property changes through different pathways.

As an eco-friendly special paper, sulfur-free paper is increasingly favored by industries such as electronics manufacturing and food packaging due to its strict control and avoidance of sulfur-containing compounds during production. This article comprehensively analyzes the shelf life standards, key influencing factors, scientific storage methods, and common mistakes of sulfur-free paper, helping users in related industries fully leverage the performance advantages of this material.

The fully refined kraft paper made of all wood pulp by Kangchuang Paper uses 100% unbleached coniferous wood pulp. This raw material makes the color of the paper stable, the paper texture fine and uniform, the thickness consistent, and the paper surface free of wrinkles, joints, damages, and loose edges. It has the advantages of strong toughness and good tensile force. Let's first talk about the quality of our kraft paper.
