Introduction
Tissue products are judged by softness, bulk, and strength simultaneously. Market pressure encourages lower basis weight for sustainability and cost, but reduced fiber mass can destabilize strength and converting performance. Conventional routes aggressive refining or heavy resin dosing often reduce softness and create harsh handfeel. Paper Save was developed to increase strength-to-weight efficiency through network reinforcement compatible with microcellulose structuring, supporting robustness without compromising sensory perception.

1. The Technical Challenge
At low basis weight, tissue sheets are more sensitive to breaks, dusting, and loss of wet integrity. Increasing strength often increases bonding density and reduces softness. The challenge is to build a reinforcement strategy that improves tensile performance efficiently while keeping bulk and handfeel acceptable.
.
2. The SAVE Solution: Controlled Bonding Architecture
Paper Save supports strength by reinforcing the fiber network through a controlled bonding architecture that complements microcellulose structuring. This reduces dependency on harsh refining and minimizes the need for heavy chemical strength strategies that can harm softness.

3. Mechanism of Action in the Sheet Structure
Paper Save contributes through:
- improved fiber network cohesion and bonding efficiency,
- stabilization of microcellulose-driven reinforcement mechanisms,
- improved structural uniformity supporting converting performance,
- balanced strength development with reduced softness penalty.
.
4. Practical Outcomes
In tissue development, this approach typically supports:
- improved strength at lower basis weights,
- reduced converting breaks and dust generation,
- preserved softness and bulk perception,
- improved quality stability under humidity changes.
.
Conclusion
Paper Save enables stronger tissue at lower basis weight by improving bonding efficiency and reinforcing the network in a microcellulose-compatible way protecting softness while improving industrial robustness.
