Fit-to-Product Packaging Machines: How They Work and What They Cost

Every corrugated packaging professional has seen the problem: a small product rattling around inside an oversized box, surrounded by void fill material that the customer immediately throws away. This is the problem that fit-to-product packaging machines — also known as box-on-demand or right-size packaging systems — are designed to solve.

These machines create a custom-sized corrugated box for every order, built to fit snugly around the product with minimal or zero void fill. The technology has been adopted rapidly in e-commerce fulfillment and is expanding into manufacturing, third-party logistics, and traditional corrugated box plants. Here is how these systems work, what they cost, and how to evaluate whether one makes sense for your operation.

The Problem With Standard Box Sizes

Most companies ship products in a limited set of standard box sizes. A typical e-commerce fulfillment operation might stock 10 to 30 box sizes to cover its product range. A manufacturer shipping parts might use 5 to 15 standard sizes. The result is inevitable: most products do not perfectly fit any of the available box sizes, so they ship in a box that is larger than necessary.

The costs of over-sized packaging are significant:

Material Waste

Every square inch of excess corrugated board is wasted material. Studies consistently show that the average corrugated shipping box is 30-40% larger than necessary for the product it contains. At current containerboard prices, this excess material adds up quickly across high shipping volumes.

Void Fill Costs

When the box is larger than the product, the void space must be filled to prevent product damage during transit. Air pillows, paper fill, foam peanuts, and inflatable dunnage all cost money — both the material itself and the labor to dispense it. Many fulfillment operations spend $0.15 to $0.50 per package on void fill alone.

Shipping Cost

Dimensional weight pricing, used by all major carriers, means shippers pay for the size of the box, not just the weight. An oversized box that tips into a higher dimensional weight tier can add $1 to $5+ per shipment in excess freight costs. For high-volume shippers, this is often the single largest cost associated with oversized packaging.

Truck Utilization

Oversized boxes waste trailer space. When boxes are right-sized, more packages fit per truck, reducing shipping costs and carbon emissions. The pallet and truckload efficiency gains from right-sizing can be substantial.

Environmental Impact

Excess material, void fill, and wasted truck space all translate to unnecessary environmental impact — more trees harvested, more energy consumed, more emissions generated. Sustainability-conscious brands and consumers are increasingly attentive to this waste.

How Fit-to-Product Machines Work

The Basic Process

All fit-to-product machines follow a similar fundamental process:

1. Measure or receive dimensions — The system determines the dimensions of the product(s) to be packed, either through 3D scanning, weighing, or data from the warehouse management system (WMS)
2. Calculate optimal box size — Software determines the minimum box dimensions that will contain the product(s) with appropriate clearance
3. Cut and score corrugated material — The machine converts flat corrugated stock (either fanfold board from a continuous roll or pre-cut blanks) into a custom blank with the calculated dimensions
4. Form the box — The blank is folded and erected into a finished box, ready for the product to be inserted

Fanfold-Fed Systems

The majority of fit-to-product machines use fanfold corrugated board — continuous corrugated material folded in a zigzag pattern and stacked on a pallet. The machine feeds board from the fanfold stack, measures the required length, and cuts, scores, and folds it into a box.

Fanfold systems offer the greatest flexibility because the box length is limited only by the width of the fanfold material and the machine's maximum blank size. Box width and height are determined by the score pattern cut into the board.

Sheet-Fed Systems

Some systems use pre-cut corrugated sheets as input material. These are less flexible than fanfold systems (the maximum box size is constrained by the sheet dimensions) but can use standard corrugated board from any sheet supplier, avoiding the need for a specialized fanfold supply.

Fully Automated vs. Semi-Automated

Fully automated systems integrate with conveyor systems and warehouse management software. Products are scanned, boxes are automatically created and routed to a packing station, and in some cases, the product is automatically inserted and the box sealed — all without human intervention.

Semi-automated systems create the custom box, but a human operator inserts the product and seals the box. These systems are simpler to integrate, lower in cost, and appropriate for operations with diverse product types that are difficult to automatically pack.

Major Manufacturers

Packsize

Packsize is the market leader in box-on-demand systems, with the largest installed base worldwide. Their product line includes:

• X7 — A higher-throughput system for large-scale fulfillment centers, producing up to 1,000+ boxes per hour
• X5 — A mid-range system suitable for medium-volume operations
• iQ Fusion — Designed for smaller operations and higher-mix product environments

Packsize uses a proprietary fanfold corrugated supply system. Customers purchase or lease the machines and buy corrugated fanfold material from Packsize. This bundled hardware-and-material model has been Packsize's primary business approach, though the specifics vary by market and customer size.

CMC Machinery (now part of Mayr-Melnhof Group)

CMC is an Italian manufacturer whose CartonWrap system is widely used in e-commerce fulfillment. The CartonWrap uses fanfold corrugated board and wraps it around the product (rather than creating an open box), creating a snug, tight-fitting package with minimal void space.

Key features:

• Very high throughput — up to 1,000+ packages per hour
• Products are placed on the corrugated blank before wrapping, enabling full automation
• Creates a "wrap-around" style package rather than a traditional box
• Widely adopted by major e-commerce retailers

Sparck Technologies

Sparck (formerly Neopost Packaging) manufactures the CVP Everest and CVP Impack systems. These are fully automated fit-to-product systems that use 3D scanning to measure products, then create and seal a custom box — all in a single automated process.

Key features:

• Integrated 3D scanning — no need for pre-measured product dimensions
• Fully automated box creation, product enclosure, and sealing
• Throughput of 450-1,100+ packages per hour depending on model
• Uses fanfold corrugated material

Quadient (formerly Neopost)

Quadient's CVP line of automated packaging systems creates custom-fit packages using a wrapping process similar to CMC. Products are measured, a corrugated blank is cut to size, and the material is folded around the product and sealed.

BW Packaging (Barry-Wehmiller)

BW Packaging offers fit-to-product systems through its various operating companies, including solutions from Packsize (as BW Packaging acquired a portion of this market through partnerships and its own development).

Other Manufacturers

Several additional manufacturers offer box-on-demand or fit-to-product systems, including:

• Kolbus Autobox — Compact box-on-demand systems for lower-volume applications
• Panotec — Italian manufacturer of box-making and wrapping systems
• Ranpak — Known primarily for void fill and cushioning systems, Ranpak also offers box-on-demand machines
• WestRock (now Smurfit Westrock) — Offers proprietary box-on-demand solutions as part of their packaging services

Cost Analysis

Machine Costs

Fit-to-product machine pricing varies widely based on throughput, automation level, and business model:

Some manufacturers offer lease or pay-per-box models instead of outright purchase, which reduces upfront capital requirements but increases per-unit costs.

Material Costs

Fanfold corrugated material typically costs 10-25% more per square foot than equivalent standard corrugated board. However, because right-sized boxes use significantly less material per package, the net material cost per package is usually lower despite the higher per-square-foot price.

A typical analysis shows:

• Standard box approach: Average box uses 6.5 sq ft of corrugated at $0.12/sq ft = $0.78 per box + $0.25 void fill = $1.03 per package
• Right-size approach: Average box uses 4.2 sq ft of corrugated at $0.15/sq ft = $0.63 per box + $0.00 void fill = $0.63 per package
• Savings: $0.40 per package in material alone

At 10,000 packages per day, that is $4,000 per day or roughly $1 million per year in material savings.

Labor Costs

Fully automated systems dramatically reduce labor at the packing station. Instead of an operator selecting a box, assembling it, placing the product, adding void fill, and sealing, the automated system handles everything except (in some configurations) product placement. Labor savings of 1-3 workers per shift per machine are typical for high-throughput systems.

Shipping Cost Savings

The largest single savings component is usually reduced shipping costs from right-sized boxes. Typical savings range from $0.50 to $3.00+ per package, depending on the degree of current oversizing and the carrier pricing structure. For dimensional-weight-sensitive shipments (light products in large boxes), the savings can be even more dramatic.

Total Cost of Ownership

A comprehensive ROI analysis for a fit-to-product system should include:

Savings:

• Reduced corrugated material usage
• Eliminated or reduced void fill
• Lower shipping costs (dimensional weight)
• Labor reduction at packing stations
• Improved truck utilization
• Reduced damage claims (tighter fit means less product movement)

Costs:

• Machine capital cost or lease payments
• Fanfold material premium over standard board
• Installation and integration
• Maintenance and spare parts
• Operator training
• Floor space

For high-volume e-commerce and fulfillment operations (5,000+ packages per day), ROI payback periods of 6 to 18 months are common. For lower-volume operations, payback extends to 18 to 36 months, and below a certain volume threshold, the economics may not justify the investment.

When Does Fit-to-Product Make Sense?

Strong Fit

• High shipping volume — 2,000+ packages per day provides the volume to justify the machine investment
• High product size variability — If you ship products ranging from book-size to microwave-size, the right-sizing benefit is maximized
• Dimensional weight pricing — If you ship via parcel carriers that charge by dimensional weight, the shipping savings are substantial
• Significant void fill usage — If you are spending heavily on void fill materials and labor, eliminating this cost drives strong ROI
• Sustainability goals — If your organization or customers demand reduced packaging waste, right-sizing delivers measurable improvements

Weak Fit

• Low shipping volume — Below 500 packages per day, the machine cost may not be justified
• Uniform product sizes — If most products fit well in 2-3 standard box sizes, the right-sizing benefit is minimal
• Freight-class shipping — If most shipments go by LTL or truckload rather than parcel, dimensional weight pricing may not apply
• Heavy products — If products are dense enough that actual weight always exceeds dimensional weight, right-sizing does not reduce shipping costs (though material savings still apply)

Implications for Corrugated Box Plants

Threat or Opportunity?

Fit-to-product machines represent a shift in how corrugated packaging is consumed. Instead of box plants selling pre-made boxes in standard sizes, the end-user creates their own boxes from corrugated raw material. This can feel threatening to traditional box plant business models.

However, the corrugated material still needs to come from somewhere. Fanfold corrugated is produced on corrugators and converted on specialty equipment, creating a supply opportunity for corrugated manufacturers. Some integrated producers and independent sheet plants have invested in fanfold converting capability to supply the growing box-on-demand market.

Selling Against Box-on-Demand

For corrugated sales professionals, understanding fit-to-product technology is essential. When a customer is evaluating box-on-demand, the corrugated salesperson should:

• Help the customer conduct a thorough ROI analysis, including all costs (not just the vendor's optimistic projections)
• Offer alternative right-sizing approaches: more SKUs of standard boxes, pre-scored blanks that can be folded to different heights, or telescoping box designs
• Position value-added features that box-on-demand cannot easily replicate: high-quality flexo printing, die-cut retail-ready designs, specialty coatings and treatments
• If the customer is going to adopt box-on-demand, position your plant as the fanfold supplier

Installation and Integration Tips

Facility Requirements

• Floor space — Most systems require 200 to 600 square feet for the machine plus infeed/outfeed conveyors and material staging
• Ceiling height — Fanfold material is typically loaded from above by forklift; ensure adequate clearance
• Power — Most systems require 480V three-phase power, though some smaller units run on 208V
• Compressed air — Required for most systems; check the CFM and pressure requirements against your plant's air supply
• Network connectivity — For WMS integration and remote monitoring

WMS Integration

The greatest benefit of fit-to-product machines comes from integration with the warehouse management system. When the WMS communicates product dimensions and order information directly to the box-making machine, the process is fully automated and optimized. Budget time and resources for this integration — it is often the most complex part of the project.

Material Supply Chain

Securing a reliable supply of fanfold corrugated at competitive pricing is critical to long-term ROI. Negotiate material contracts before committing to a machine purchase, and establish backup supply sources. Some machine manufacturers bundle material supply with the equipment, which simplifies procurement but may limit negotiating leverage.

The Market Trajectory

The fit-to-product packaging market is growing at 15-20% annually, driven primarily by e-commerce volume growth and carrier dimensional weight pricing pressures. As machine costs decrease and throughput increases, the technology will become economically viable for smaller operations.

For the corrugated industry, this technology does not threaten the need for corrugated board — it actually increases consumption by converting some shipments that currently use poly mailers or non-corrugated packaging to corrugated boxes. The shift is in where and how the box is made: at the point of fulfillment rather than at the box plant.

Corrugated manufacturers who adapt to this shift — by supplying fanfold material, offering right-size design services, or integrating box-on-demand equipment into their own value-added services — will capture growth rather than lose market share.
