Post-Consumer Recycled (PCR) Paperboard: Strength Degradation and Optimization

Incorporating 100% post-consumer recycled (PCR) waste reduces carbon footprint but reduces tensile strength.

Cellulose Fiber Shortening

Each paper recycling cycle shortens cellulose fibers, reducing bursting strength and fold flexibility over time.

Hybrid Fiber Blending Strategies

Blending 70% PCR content with 30% long-fiber virgin FSC softwood pulp restores carton structural rigidity for e-commerce transit.
