What Honeycomb Paperboard Can Do For Your PackagingBy：Bingyi Ma

How Smarter Materials Reduce Costs, Damage And Waste

A packaging system with the proper structural material helps to reduce cost, damage, and waste. Honeycomb paperboard has high compressive strength yet low weight - it means that you need less layers of protection to protect the same product in comparison to conventional boards or foam blocks.

Better energy absorption results in less shipments being rejected due to crushed corners or internal breakage. That reduces reverse logistics, customer service workload and write offs. A lighter but stronger structure reduces the material bill, the freight cost and dramatically the volume of plastic or EPS going to landfills.

Why Buyers Now Notice What’s Under The Box, Not Just What’s On It

Customers are becoming much more literate about what goes inside and around a product. They look for recycling symbols, point out excessive void fill in reviews and share unboxing videos praising or railing against packaging choices.

Brands who use structures that are made of visibly and clearly recyclable paper versus an anonymous white foam communicate that they are concerned about environmental impact. Honeycomb paperboard does look very much like engineering and it's premium to the touch, but it reads as "paper" which makes it more palatable for customers to dispose of responsibly.

What Exactly Is Honeycomb Paperboard?

From Beehive To Box: The Science Of The Core

Honeycomb paperboard is nature inspired. Thin strips of kraft or testliner paper are glued and expanded into a matrix of hexagonal cells - the same shape bees use in their hives.

This cellular core is in turn sandwiched between flat facing sheets. The panel is like a lightweight I-beam grid with the core carrying loads from one facing to the other, resisting compression and bending with surprising efficiency for such a low-density material.

How The Sandwich Structure Works: Facings, Core And Adhesive

Honeycomb paperboard is an all-time sandwich composite:

• Facings take up most of the tensile and compressive stresses when the board is bent or stacked.
  
• takes the load and spreads it around a large area by having the core stabilize the facings and prevent buckling.
• The adhesive is used to bond the facings and the core to maintain the panel in one structural unit.

Because so much of the volume is trapped air, the board provides a high strength - to - weight ratio - more performance for each gram of fiber and less deadweight in the supply chain.

Important Specs Explained In Simple Terms (GSM, Thickness, Cell Size)

There are three key parameters for designers and buyers:

• GSM (grams per square meter) – the basis weight of the paper used. Higher GSM generally means stronger facings and a stronger core, which improves mechanical performance.
• Thickness – the overall thickness of the panel, which can range from a few millimeters to several centimeters. Thicker panels provide more cushioning and higher stacking strength.
• Cell size – the diameter of each hexagonal cell. Smaller cells increase bending stiffness and crush resistance but use more material. Larger cells reduce material usage but also reduce strength.

Balancing these three levers allows honeycomb paperboard to be tailored for everything from lightweight displays to heavy-duty pallets.

Core Benefits: Strength, Protection And Stability

Why The Strength-to-Weight Ratio is Better Than traditional Board

Honeycomb paperboard is strong yet very light weight. Often it matches or exceeds heavy corrugated or wood in terms of compression and bending stresses, at a fraction of the weight.

This is the ratio that makes it used in pallets, crates and inner structures for demanding applications. Panels are also like tiny columns; the load is shared by each of the cells, resulting in high overall capacity with much less fibre than a solid board of the same thickness.

How Honeycomb Paperboard Handles Compression And Stacking Loads

Under vertical loads - such as stacked pallets or cartons - the honeycomb core resists flattening due to its hexagonal geometry. Properly specified cores can achieve compressive strength to rival heavy duty corrugated in providing tall stacks or high pallet loads with no buckling.

This capability is of value in warehouses and containers in which stacking heights are limited by the weakest box in the column. Using honeycomb components (pallet decks, layer pads, posts) to increase overall stability of stack, reducing the risk of collapse.

Impact Protection: Keeping Things Safe In Transit

Honeycomb paperboard is not only strong, it's a great shock absorber. The cellular structure deforms further and further on impact and so energy is dissipated rather than transmitted to the product itself.

High thickness honeycomb pads can be used instead of EPS foam or molded plastic cushions for large object such as furniture, appliances, and industrial equipment. They keep products centered, protect corners and edges and reduce damage from bumps, drops, or vibration during long journeys.

Sustainability: The Environmentally Friendly Side Of Honeycomb Paperboard

Recycled Fibers, Less Material: Doing More With Less

Most honeycomb paperboard is made from recycled or sustainably sourced kraft paper. Due to performance coming from the geometry, it uses much less fiber than an equivalent solid board.

Less material implies less resource consumption upstream, less weight in transport and less pieces of packaging in the waste stream. This efficiency is a powerful lever to the brands looking for meeting CO2 and waste reduction targets.

How Honeycomb Paperboard Helps Reduce Plastic And Foam

Replacing plastic foams or other non-recyclable components is a major victory. Honeycomb boards and blocks can be die cut and laminated into pads, corner posts, cradles and edge protectors that would normally be produced using EPS or moulded plastic.

Consolidating mixed-material packs into primarily paper based systems makes them easy to recycle. Customers can flatten everything and put it in the paper stream instead of having to empty out foam inserts that usually wind up in landfill.

End-Of-Life Options: Recycling, Reuse And Responsible Disposal

When it's time to get rid of honeycomb paperboard you can:

• Recycle: In most markets, honeycomb paperboard can be recycled along with other paper products, as long as it’s not heavily contaminated.
• Reuse for internal logistics: Within companies, used honeycomb board can often be reused multiple times for internal transport or protective packaging.
• Responsible incineration with energy recovery: If recycling or reuse isn’t feasible, honeycomb paperboard can be incinerated in facilities equipped for energy recovery. This still results in a significantly lower long-term environmental footprint compared to persistent plastics.

Because it is a mono-material, obviously paper-based solution, honeycomb aligns well with emerging extended producer responsibility schemes and retailer packaging guidelines.

Cost And Logistics: Saving Money Beyond The Box

How Honeycomb Paperboard Reduces Shipping Costs Per Unit

Weight is a long term enemy of logistics. Honeycomb pallets, crates and components are frequently dramatically lighter than wooden counterparts that can handle similar loads.

Reduced weight of packaging reduces airfreight costs and sea freight efficiency. For high-volume shippers, even small weight saving per unit could result in large savings in a year.

Pallet Optimization: More Pallets Per Load, Fewer Trips

With lighter, but structurally capable pallets and supporting, you can optimize cube utilization inside containers and trailers. Lower tare weight permits more weight of product that is legally permissible and robust stacking strength permits higher columns that do not collapse.

In practice, this can mean fewer trucks on the road or fewer containers on the water for the same volume going out-the-door - reducing both the cost of freight, and emissions.

Handling, Labor And Storage: Hidden Savings In Your Supply Chain

Lightweight parts and components are easier to move, assemble, and reposition on the floor of the warehouse. Workers are able to manipulate honeycomb pads, blocks and pallets without the use of special equipment, which lowers ergonomic risk and helps to accelerate packing lines.

Due to the fact that honeycomb components are often delivered flat or nested, they take less storage space before they're used and will free up valuable warehouse real estate for product, not packaging.

Where Honeycomb Paperboard Fits In Your Packaging System

Transit Packaging: Pallet Tops, Layer Pads And Blocking

Honeycomb is ideal for pallet tops, interlayer pads and blocking panels for export/long haul shipments. These components are spread loads, protection of product faces and prevent movement in the unit load.

Replacing heavy sheets of wood or multiple corrugated layers with a single honeycomb panel provides for improved performance with fewer SKUs and simpler packing instructions.

Inner Protection: Inserts, Braces, Edge Protectors And Cradles

Inside the carton, honeycomb structures can be:

• Die-cut inserts that securely lock products in place
• Fly braces – vertical posts that redirect load away from the product
• Edge and corner protectors that shield vulnerable areas from impact
• Cradles designed to conform to curved surfaces, such as drums or appliance casings

These elements give designers a modular toolkit to protect heavy or fragile items without sacrificing mono-material construction and ease of recycling.

Retail And POS: Structural Displays, Risers & Platforms

Honeycomb paperboard also performs well on the store floor. Large-format panels can be turned into impressive displays, podiums and risers that bear substantial weight while remaining fully printable and brandable.

The thickness of the material enables crisp edges and bold silhouettes that stand out in retail environments. When the promotion ends, the entire display can be flattened and directed into the paper recycling stream.

Honeycomb Paperboard Vs Other Packaging Materials

Honeycomb Paperboard Vs Corrugated: When To Upgrade

Corrugated board is a work horse, but it has its limits. When loads are heavy, pack sizes large or stacking heights aggressive, traditional corrugated often requires multiple layers or reinforcement.

Honeycomb paperboard has higher compressive strength and better thermal insulation performance at the same weight, and is a great upgrade in the complex requirements such as industrial parts, automobile parts and export crates.

Honeycomb Paperboard Vs Foam And EPS: Cushioning Without The Guilt

Foam and EPS have a high degree of cushioning, but have a high environmental impact and are now subject to restrictions those in the environment and by retailers.

High thickness honeycomb pad formers can absorb similar or more amounts of energy per unit volume with robust cushioning while still being wholly paper-boned and widely recyclable.

Honeycomb Paperboard Vs Wood And MDF: Lighter Hardware, Similar Strength

Wooden pallets and MDF structures are strong but heavy, and liable to splinter, and require special treatment for international shipping. Honeycomb pallets and decks are on par with wooden alternatives in terms of load capacity, but are much lighter and do not require fumigation.

For exporters and brands shipping into multiple regions, this lessens administrative friction and facilitates compliance.

Paperboard Designing With Honeycomb Paperboard

Selecting Thickness, Density And Facing Papers

Effective design starts with matching structure to load:

• Heavy Loads or High Stacking Heights - Heavy loads or high stacking height - Use higher density cores and heavier facings.
• General industrial use – choose mid-range densities to balance cost and strength.
• Displays, signage and light consumer items – use lighter cores and facings to minimize cost and weight.

Lab data and supplier input help match thickness, GSM and cell size to real-world load profiles.

Design Rules For Slots, Cutouts, Holes And Hardware Fixings

As with any composite panel, careful detailing preserves performance:

• Avoid large holes or deep cutouts in high-stress areas such as supports and corners.
• When using bolts or screws, distribute loads with wide washers or plates.
• Use engineered edge closures or fillers where edges will be heavily loaded or impacted.

These rules maintain facing and core continuity, which is critical to the structural integrity of the panel in real use.

Testing For Real-World Loads: Drop, Vibration And Compression

Given the demanding nature of logistics chains, prototypes should be validated through:

• Compression tests to confirm stacking performance
• Drop and impact tests to understand damage thresholds
• Vibration tests for long-haul transport or sensitive electronics

This blended testing approach is essential when replacing foam or mixed-material packs with a new structural concept.

Branding And Unboxing: Turning Structure Into Story

How Printed Honeycomb Paperboard Increases Brand Perception

Honeycomb panels in the form of paper facings can be printed, laminated or branded like premium corrugated. Their thick and rigid form coupled with clean graphics creates a premium engineered appearance that sticks in the minds of customers.

From a brand perspective being able to say that protection, pallets and structural elements are all paper-basis adds a powerful story behind innovation and responsibility.

Designing Clean, Minimalist, “Engineered” Aesthetics

Honeycomb paperboard lends itself well to a minimalist design: Sharp edges, clear thickness and simple shapes. Exposed edges are not a flaw, but a design element, expressing honesty and structural elegance.

Paired with restrained graphics and clear recycling cues, these elements produce packaging that's both modern and conscientious looking.

Unboxing That Feels Premium But Still Looks Responsible

You can make an unforgettable unboxing without having to use any additional plastic, foam or tissue. There are honeycomb inserts that hold things in a sculpted, precise shape - there's care and craft behind that, and they are obviously recyclable.

Customers see an intelligently designed inside and immediately know that the brand has invested in protection and environmental accountability.

Real-World Applications Across Industries

Furniture And Home Goods: Flat-Pack Protection That Works

Flat pack furniture, shelving and home goods are often heavy and bulky, as well as prone to edge damage. Honeycomb pads and blocks are used to shield corners, support and protect panels and surfaces without adding extra weight to large parcels.

Electronics And Appliances: Securing High-Value, High-Risk Loads

Large TVs, white goods and electronics require high-quality cushioning and stable blocking for their transit. Honeycomb cradles and corner posts provide security for these products against compression, drops, and vibration and prevent or reduce EPS foams.

Industrial And Automotive Parts: Heavy Duty Without Heavy Weight

Industrial components and automotive parts are often in need of export grade protection and powerful unit loads. Honeycomb pallets and dunnage offer high load capacity and low weight, making them perfect for containerized shipments and just-in-time deliveries.

E-Commerce And DTC Brands: Smarter Shipping For Small Businesses

For e commerce and DTC brands, shipping costs, damage rates and customer perception are critical. Honeycomb inserts and pads provide an opportunity to increase protection and unboxing while not making recycling more complicated for end customers.

Smaller brands that incorporate honeycomb structures are able to withstand the competition with packaging that seems custom-engineered, even at relatively modest order levels.

Is Honeycomb Paperboard Right For Your Product?

Important Questions About Weight, Fragility & Journey Distance

Before switching, consider:

• How heavy is the product, and how tall will the stacks be that are planned?
• How fragile is it and what kinds of shocks/drops can be expected?
• How long is the journey and how many touch-points are involved?

Products which are heavy, high-value or involve long travel distances with several stages of handling are ideal candidates for honeycomb optimization.

When A Hybrid System (Honeycomb + Corrugated) Makes Sense

In many cases the best solution is a hybrid: corrugated cartons with inserts made of honeycomb, layer pad or pallets. Corrugated supplies exterior print surfaces as well as familiar case formats, while the honeycomb bears bulk loads, edges and replaces plastic or wood parts.

Red Flags: When Honeycomb Paperboard May Not Be Suitable

Honeycomb may not be suitable when:

• Packaging will be exposed to standing water or extreme humidity several times without adequate sealing.
• Very small, intricate parts need micro precision cavities better suited to molded pulp or thermoformed plastics.
• The pack shall be able to withstand repeated rough handling well beyond normal logistic conditions without damage or being crushed.

In these edge cases specialist materials or other coatings and reinforcements may be needed.

Implementation Roadmap: From Trial To Rollout

Auditing Your Current Packaging For “Quick Win” Replacements

A practical starting point is a packaging audit focused on:

• Heavy wood or MDF components that could be lightened
• Foam and EPS cushions that could be substituted
• Multi-layer corrugated stacks that might be consolidated

These “quick win” areas often deliver immediate savings with minimal redesign of the outer pack.

Prototyping And Sampling With Your Converter Or Supplier

Work with converters and/or honeycomb experts to create samples based on your SKUs. Use actual products and realistic loads instead of generic test pieces.

Quick iterations at this stage assist with fine tuning thickness/cell-size/facings before undertaking any large scale tooling or automation changes.

Running Trials: Lab Tests, Pilot Shipments And Customer Feedback

Combine formal tests and field trials:

• Run standard transport and compression test protocols where applicable.
• Make pilot shipments using typical routes and carriers.
• Collect feedback on performance and unboxing from warehouses, retailers and end customers.

This combined approach ensures the solution works in both controlled and real-world conditions.

Cost Modeling: Looking Beyond Price Per Piece

In considering honeycomb, look at total landed cost not unit price:

• Packaging material spend
• Inbound and outbound freight costs
• Damage and return rates
• Handling cost, storage cost and disposal cost
  

In many implementations, freight savings and damage reduction more than offset any marginal increase in material cost.

Common Mistakes To Avoid With Honeycomb Paperboard

Over-Engineering And Over-Specifying Thickness Or Grade

Honeycomb has a strong feel to it, so it is tempting to specify very thick panels "just in case." This rapidly destroys benefits of costs and sustainability.

Data drived specification based on real loads and tests helps to avoid over engineering and keeps the design lean.

Neglecting Moisture, Humidity And Storage Conditions

Like all paper based materials, honeycomb is sensitive to long term moisture and extreme humidity. Designs that do not take into account storage conditions, condensation risks or outdoor exposure may underperform.

Protective coatings, liners, or intelligent handling protocols minimize these dangers where needed.

Designs That Don’t Match Your Packing Line Or Automation

A fabulously-engineered honeycomb insert to slow the line down or require new equipment adds operational friction.

Designs should take into account the reality of manual packing, semi automation or full automation - fold, orientation and repeatability all matter.

Skipping Training For Packers On Assembly And Handling

Even the best of designs is useless if packers do not know how to assemble or position it correctly. Brief training, suitable diagrams and easy-to-follow instructions can be assured that honeycomb components are used as intended and provide full protective performance.
