13 October 2025Right-Sizing and On-Demand Boxing: The Smart Future of Sustainable Fulfillment
When Every Box (and Gram) Matters
In modern e-commerce logistics, packaging is no longer just a container — it’s a cost driver, a sustainability lever, and a customer-experience touchpoint. The rise of on-demand packaging and right-sizing technology marks a turning point for 3PLs and online retailers seeking to balance speed, cost, and environmental responsibility.
Every day, millions of oversized boxes are shipped across Europe, wasting space, increasing shipping costs, and producing unnecessary emissions. A study by DS Smith estimates that empty space in e-commerce packaging accounts for over 40% of truck volume — meaning nearly half of logistics capacity is spent transporting air.
Right-sizing and on-demand boxing solve this inefficiency by producing custom-fit boxes in real time, matched perfectly to each order’s dimensions. What was once a manual, error-prone process has become a data-driven operation — powered by AI, sensors, and automated cutting machines.
For companies like FLEX Logistik, these technologies represent the next evolution of sustainable fulfillment — where packaging becomes an intelligent, adaptive system that reduces waste, optimizes costs, and enhances the unboxing experience.
"FLEX Logistik uses right-sizing and on-demand packaging to reduce waste, optimize transport, and enhance sustainability across e-commerce supply chains."
OUR GOAL
To provide an A-to-Z e-commerce logistics solution that would complete Amazon fulfillment network in the European Union.
1. What Is Right-Sizing?
Right-sizing refers to the process of creating packaging that fits a product’s exact size and shape — neither too large nor too small.
Instead of relying on a limited set of box sizes, logistics systems automatically calculate the optimal packaging volume based on real-time order data.
Core Benefits:
- Less air, more efficiency: Maximizes truck and container utilization.
- Lower materials cost: Uses up to 30% less corrugated board per shipment.
- Reduced dimensional weight (DIM) charges: Carriers increasingly price by package volume, not weight.
- Fewer damages: Tight-fit boxes prevent product movement in transit.
- Improved sustainability: Smaller boxes = less filler, tape, and carbon footprint.
In practice, right-sizing uses algorithms that analyze SKU dimensions, order composition, and carrier rules to select or generate the ideal box.
This allows fulfillment centers to adapt packaging dynamically — even for multi-item or oddly shaped orders.
"Right-sizing technology ensures every product is packed in a perfectly fitted box — reducing waste, costs, and carbon emissions."
2. On-Demand Boxing: Packaging as a Service
Traditional packaging workflows rely on pre-produced boxes stacked in inventory.
On-demand systems turn this model upside down.
Using automated box-making machines, warehouses can now cut, fold, and print boxes on the spot, one order at a time.
How It Works:
- The WMS sends order dimensions to a connected on-demand packaging machine.
- The system measures the combined size of items and selects the smallest possible footprint.
- The machine automatically cuts and folds corrugated sheets into a perfectly sized box.
- Optional branding, labels, or QR codes are printed directly on the surface.
- The package proceeds to auto-sealing or manual packing.
These systems, offered by companies like CMC, Packsize, or Panotec, can produce hundreds of boxes per hour — all customized in shape, branding, and size.
"Right-sizing technology reduces material use, transport costs, and CO₂ emissions — turning sustainability into a measurable business advantage."
3. The Business Case: Cost, Space, and Sustainability
While initial equipment investment can be significant, the ROI on right-sizing is fast and measurable.
Cost Savings
- Material reduction: Less corrugated cardboard and filler (bubble wrap, paper, etc.).
- Freight optimization: Up to 25% lower transport cost through better cube utilization.
- Storage efficiency: No need for large inventories of pre-made boxes.
Space Utilization
- Fewer box types → smaller packaging areas.
- Better stacking efficiency in trucks and warehouses.
- Dynamic layouts supported by automated packing lines.
Sustainability Gains
- Less packaging waste and CO₂ emissions.
- Easier recycling due to standardized, mono-material packaging.
- Lower energy consumption during production and shipping.
For environmentally conscious brands, these numbers translate directly into CSR metrics and ESG reports, supporting compliance with EU sustainability initiatives such as the Packaging and Packaging Waste Regulation (PPWR).
4. Data as the Engine of Right-Sizing
At the heart of on-demand boxing lies data — accurate, structured, and actionable.
Each packaging decision depends on a web of variables:
- Product dimensions and fragility
- Order composition (single vs. multi-item)
- Carrier volumetric pricing
- Regional shipping restrictions
- Sustainability preferences (e.g., recycled board)
When synchronized through ERP, WMS, and carrier APIs, these data points allow automated systems to generate the ideal box specification in milliseconds.
Companies like FLEX Logistik leverage data hygiene and machine learning models to continuously refine these calculations.
Every shipment becomes a feedback loop: measuring box utilization, material waste, and shipping cost — feeding insights back into the algorithm.
5. Integrating Right-Sizing into Fulfillment Workflows
Transitioning from standard packaging to right-sizing requires rethinking workflows.
Here’s how leading 3PLs integrate the process step-by-step:
A. Data Capture
SKU dimensions and weights are scanned or imported into the WMS.
Dynamic measurement tools (camera scanners or laser cubing systems) ensure continuous accuracy.
B. Order Grouping
Orders are categorized by size, fragility, and destination — optimizing batch runs for the box-making system.
C. Box Generation
On-demand machines produce right-sized boxes in real time, automatically labeled with the order ID and shipping barcode.
D. Automated Packing
Integration with robotic arms or semi-automatic stations minimizes manual handling.
E. Feedback & Optimization
Each package generates data on volume, filler usage, and transport cost, enabling long-term refinement.
6. Customization and Branding: The Hidden Opportunity
Right-sizing doesn’t only cut waste — it elevates branding.
With digital on-demand printing, each box can carry:
- Personalized logos or greetings.
- QR codes linking to digital product passports (DPP).
- Customer-specific promotions or return instructions.
This transforms packaging from a cost into a marketing asset.
A well-designed unboxing experience drives repeat purchases and brand loyalty — crucial for D2C and subscription-based models.

- Integrate with warehouse digital twins for process simulation.
Together, these technologies form the foundation of smart packaging ecosystems, where physical packaging responds dynamically to digital intelligence.
"AI and IoT technologies power next-generation packaging systems, enabling predictive right-sizing, automation, and zero-waste fulfillment."
9. Regulatory Alignment: PPWR and Circular Packaging
The upcoming EU Packaging and Packaging Waste Regulation (PPWR) will further accelerate right-sizing adoption.
Its goals include:
- Reducing packaging waste by 15% per capita by 2040.
- Requiring 100% recyclability for all packaging.
- Incentivizing reusable and returnable packaging systems.
Right-sizing directly supports these objectives by minimizing material waste and standardizing recyclability.
For 3PLs, compliance will soon be impossible without digital proof of packaging optimization — tracked through DPP (Digital Product Passport) frameworks.
10. The Future: From Smart Boxes to Zero Waste Fulfillment
In the near future, packaging will no longer be static.
Smart materials, embedded sensors, and connected data streams will turn every box into a digital node in the supply chain.
Imagine:
- Boxes that self-report damage or temperature changes.
