Mondi redesigns corrugated packaging system for Stiebel Eltron water heaters

Mondi has developed a new corrugated packaging concept for Stiebel Eltron's water heater range, cutting the number of board grades used by more than 75% while switching to white digital printing on brown board. The redesign covers 150 packaging variants and is intended to simplify procurement, production and logistics while supporting faster rollout of future product launches.

Why this mattersThe project shows how board-grade consolidation and digital printing can cut complexity costs for industrial customers, a template converters can pitch to other multi-SKU manufacturers.

• Mondi reduced the number of corrugated board grades used across Stiebel Eltron's packaging by more than 75%.
• Stiebel Eltron had 150 packaging variants in use before the redesign.
• The redesign converts four-colour printed designs to white digital printing on brown corrugated board.
• Mondi grouped existing packaging by product weight and transport requirements to identify optimal board grades per group.
• Digital printing allows multiple designs and print volumes on the same material base without additional set-up.
