Design and Preparation of High‐Performance Paper Composites for Reclosable Packaging

Finished box paper‐based materials, particularly those used for food packaging, are widely utilized, and their performance critically influences product usability and storage longevity. Addressing prevalent issues such as inadequate sealing properties, suboptimal mechanical performance, and poor reusability in existing food packaging solutions, this study developed high‐performance finished boxes with resealable structures and reusable bonding capabilities through systematic improvements in manufacturing processes and structural design. The research methodology involved comparative optimization of paper‐based material preparation techniques, structural design, and comprehensive performance benchmarking. The resultant material achieved significant advancements in multiple aspects: reduced weight, enhanced stiffness, improved bonding strength, low oxygen transmission rate (OTR) and exceptional durability for prolonged cyclic use (demonstrating a mere 0.3 decay after 20 cycles, equivalent to a minimal decay rate of 10%). This innovative development establishes a solid scientific foundation for enhancing the performance of finished box paper‐based materials and provides valuable technical references for refining material preparation methodologies in industrial applications.
