With its investment in advanced lightweight laminating technology, the STI Group expands its capabilities in CO2-efficient, lightweight corrugated packaging. The new laminating line at the Lauterbach site is specifically designed for fine flute profiles, reduced grammages and the processing of ultra-lightweight paper and board grades, while significantly reducing waste and energy consumption.
The EU Packaging and Packaging Waste Regulation (PPWR) will apply directly in all EU Member States from 12 August 2026. The regulation requires companies to provide detailed documentation, labelling and verifiable optimisation of packaging in line with sustainability criteria. One of the key requirements of the PPWR is packaging minimisation. Lightweight corrugated packaging directly supports this objective.
STI Group applies a consistent performance-based development approach. Based on functional performance requirements such as Box Compression Test (BCT), puncture resistance and burst strength, STI Group develops corrugated board solutions that use only the material necessary to ensure product protection and logistics efficiency. This approach enables packaging minimisation without compromising performance or supply chain stability.
The new laminating technology is engineered for maximum resource and energy efficiency:
Performance-based lightweight development aligns directly with PPWR requirements, which mandate reducing packaging weight and volume to the functional minimum while maintaining demonstrable performance.
Step 1 – Define requirements (Performance setup)
We start by defining the relevant performance parameters, such as BCT, puncture resistance and burst strength.
Step 2 – Optimise material and flute combination
Based on these requirements, we develop the appropriate construction and fine-tune material quality in a clearly defined, iterative process.
The goal: maximum stability with minimal material input.
Step 3 – Make savings transparent
We quantify the results using defined KPIs, for example: Packaging weight, CO₂ footprint Performance values (e.g. BCT), Cost impact.
Lightweight Packaging at STI Group is a performance-based development approach. Packaging is designed to use only the material required for protection and logistics efficiency. Key parameters include BCT, puncture resistance and burst strength.
From 12 August 2026, the PPWR requires companies in the EU to provide greater transparency, documentation and optimisation proof for packaging. One major target: reducing packaging weight and volume. Lightweight solutions directly support this objective.
In recent years, STI Group has invested over EUR 8 million in energy- and resource-efficient laminating technology at its Lauterbach site to further expand its portfolio of CO₂-efficient lightweight packaging solutions.
The new system enables:
Because it designs packaging strictly according to functional necessity - fully aligned with the PPWR requirement to reduce packaging weight and volume to the functional minimum.
