Trim optimization: boosting efficiency in the paper industry

In today’s competitive and sustainability-driven paper industry, trim optimization — minimizing material waste during the cutting of parent rolls into customer-specific sizes — is a key lever for efficiency. 

While the concept of trim optimization seems simple, the process is complex due to varying customer requirements, machine limitations, and real-time production variables, such as quality and incidents. Poor trim optimization leads to excess waste, higher costs, and a higher environmental impact. 

Good, you have already put an effort into reducing waste 

Traditional methods often do not address these challenges fully. Outdated systems lack the flexibility and computing power to optimize across a wide range of constraints. As a result, mills face inefficiencies, increased waste, and lost profitability. 

Recent advances in algorithms and commercial solvers have transformed trim optimization. Modern solutions reduce the number of cutting patterns, use wider roll widths, and minimize waste, thus streamlining production and cutting energy and material costs. Even small reductions in trim waste yield substantial cost savings and sustainability gains. 

Artificial intelligence will give you a further boost 

Artificial intelligence (AI) takes optimization even further. AI can analyse vast operational datasets to suggest best cutting strategies, adapt to changing conditions, and predict maintenance needs. These capabilities boost both productivity and sustainability, delivering smarter, real-time decision-making. 

Today’s optimization tool 

Tietoevry’s new trim optimization solution, Trim25, exemplifies this progress. A standalone solution, it delivers measurable improvements over older systems by reducing machine time, increasing roll width use, and enhancing trim efficiency. These upgrades help mills improve converting processes while meeting both economic and environmental goals. 

 Smart decisions bring better profit 

Ultimately, trim optimization is not just a technical process. Embracing advanced tools like AI-driven solutions allows paper mills to improve performance, reduce environmental impact, and stay ahead in an evolving market. 

Making wise decisions in the choice of your tools will give you a strategic advantage.
