The challenge
The online retailer required a highly efficient and scalable solution for their new automated fulfillment center. The main challenge was to consolidate several sites into a single facility while handling a diverse inventory of boxed and hanging goods, totaling 6 million items. Additionally, the solution needed to incorporate eco-friendly practices, maximize storage capacity, and seamlessly integrate with KNAPP’s Evo Shuttle™ and pocket sortation systems.
The Solution
KNAPP and Utz collaborated closely to create the Evo Stacknest tote solution, a versatile and space-saving storage container designed to meet the specific needs of the online retailer. The tote solution was optimized for use with KNAPP’s shuttle system, allowing for efficient picking, packing, and return processes. Made from recycled materials, the containers aligned with the retailer’s sustainability goals.
Utz provided over 500,000 Evo Stacknest containers, each 650 × 450 × 330 mm, which fit seamlessly into KNAPP’s automated systems. The totes were relabeled and integrated with advanced scanning technology to ensure error-free induction into the system. Utz's on-site engineering support helped overcome mid-project challenges, such as adjustments to labeling requirements.
Implementation process
- Initial consultation: KNAPP and Utz assessed the system requirements and sustainability objectives of the customer.
- Prototype development: Utz designed prototypes of the Evo Stacknest totes, which were tested within KNAPP’s Evo Shuttle system.
- Phased rollout: After the testing phase, the solution was rolled out in phases to ensure smooth integration without disrupting ongoing operations.
- On-site support: Utz provided continuous engineering support to address challenges like mid-project design changes and system labeling.

Results
The collaboration between KNAPP and Utz led to significant operational improvements at the customer's facility:
- 25% increase in storage efficiency: By utilizing the space-saving design of the Evo Stacknest containers, the facility maximized storage capacity for its 6 million inventory items.
- Error-free scanning and induction: The totes were optimized for seamless integration with the automated scanning system, ensuring 100% accuracy in order processing.
- Sustainability gains: Utz’s containers, made from recycled materials, helped the online retailer meet its sustainability targets.
