Freight damage rarely starts with one big mistake. More often, it comes from small gaps in the securement plan that turn into bigger problems once the shipment is moving. A void is too large, the wrong material gets used, placement is off, or the load changes and the process does not change with it. For technical buyers, that puts pressure on every decision. You need a securement approach that protects the load, reduces damage risk, and holds up across real shipping conditions.
This guide is built to help with that. We cover the core categories of load securement solutions, how solution choice changes across boxcar, intermodal, over-the-road, and ocean freight, and what to look for when load shift problems keep showing up. Along the way, we break down common mistakes, planning steps, and the checkpoints that help teams build a more repeatable process from the start.
Let’s get started.
Quick Answer: What Are Load Securement Solutions?
Load securement solutions are the products, loading methods, and repeatable procedures used to keep freight from shifting, collapsing, rubbing, or absorbing avoidable impact in transit. In practice, that means looking at the full load path: pallet or package integrity, void size, contact points, weight distribution, blocking and bracing, and the right protective materials in the right places.
For most operations, the core toolkit includes dunnage air bags, void fill solutions, corrugated or interior packaging, and supporting freight protection solutions like slip sheets, corner board, stretch film, anti-slip materials, and moisture-control products like desiccants. Sunrise positions these solutions around four modalities so buyers can choose a system that fits how the load will actually move.
- Boxcar load securement
- Over-the-road freight protection
- Ocean applications
- Intermodal shipping protection
A good rule: choose the method first, then the product. If the load has open voids, lateral movement risk, mixed unit heights, or long transit exposure, your securement plan should account for those issues before the trailer or container door closes.
Why Loads Shift in Transit
Loads shift for a few repeatable reasons. The first is empty space. When unitized freight has room to move, vibration and repeated start-stop forces turn a small gap into a bigger problem. The second is weak contact between products or between the load and the container walls.
Weight distribution is another common issue. A load can look stable at the dock and still become unstable when heavier units are stacked high, concentrated to one side, or allowed to bridge across uneven surfaces. Intermodal environments add another layer because the shipment may pass through truck, rail, and terminal handling conditions before it reaches destination.
BNSF’s loading guidance highlights tight loading, proper weight distribution, and adequate blocking and bracing as basic foundations for safe arrival. Best-practice guides frame cargo securement the same way: assess the load first, then apply the right mix of airbags, void fill, and bracing.
On the floor, crews usually see the symptoms before they see the root cause (i.e. leaning stacks, open side gaps, crushed packaging, pallets that looked fine until the first hard movement) That is why transit damage prevention starts with planning and repeatable loading discipline, not a scramble for extra materials after the trailer is already half full.
The Core Categories of Load Securement Solutions
Dunnage air bags
Dunnage Air Bags are used to fill voids, stabilize cargo, and absorb impact between load units. They are cost-effective bracing solutions available in multiple sizes and configurations, including kraft paper and polywoven options.
Void fill solutions
Void Fill Solutions are the workhorses for controlling lateral movement and closing open space that would otherwise let freight drift in transit. Sunrise’s custom void filler panels and collapsible systems can be utilized effectively across boxcar, intermodal, ocean, and over-the-road applications.
Corrugated packaging and interior packaging
Corrugated materials and interior packaging protect the product itself while also improving how the load behaves as a unit. Better fit, cleaner edges, and stronger internal support reduce crush, abrasion, and movement inside the package and inside the load.
Freight protection and packaging products
Additional freight protection and packaging products round out the system. Sunrise provides all the essential supporting materials that will help you optimize safety and product protection, including slip sheets, desiccants, corner board, and stretch film and plenty more.
Blocking and bracing
Container blocking and bracing is both an efficient protection method and a system mindset. The point is to create controlled contact, prevent movement, and distribute forces where the load can handle them. Air bags and void fill can support that approach, but they do not replace good geometry, good surfaces, and sound placement.

Match the Solution to the Shipping Modality
The first step in reducing damage risk is to match the securement method to the shipping environment. At Sunrise Manufacturing, we build our approach around four shipping modalities, which makes it easier to choose the right securement method for the way the load will actually move.
Boxcar
Boxcar load securement has to manage both lateral and end-to-end impact. Loads need strong contact, reliable void control, and secure blocking where movement is most likely. Bulkheads, void filler panels, corrugated structures, and well-placed dunnage air bags are often the right starting point for rigid, high-mass shipments moving by rail.
Over-the-road
For over-the-road freight protection, the main concerns are repeated braking, cornering, vibration, and short-interval impacts from normal road movement. Loads that look stable in the yard can still walk, lean, or rub after enough miles. OTR applications often benefit from a tighter combination of void fill, anti-slip support, dunnage air bags for larger gaps, and secondary freight protection products that keep pallets and unit loads from loosening up.
Ocean
Ocean freight usually demands a longer-view approach. The motion profile is different, exposure times are longer, and moisture is a threat to compromised loads. For ocean loads, void fill and blocking still matter, but so do friction support, corrugated structures, and ocean freight moisture control measures like desiccants and protective packaging materials.
Intermodal
Intermodal shipments face a layered environment: truck drayage, terminal handling, rail movement, and sometimes longer overall dwell and transit exposure. That makes intermodal shipping protection heavily dependent on tight loading, weight distribution, and a secure mix of void fill, air bags, and blocking and bracing. BNSF’s loading guidance specifically calls out tight loading and proper weight distribution as core fundamentals.
While this information provides an excellent framework to start with, our Shipping Modalities Hub provides further detail (including our professional recommendations for product checklists per modality) to secure your load perfectly every time, no matter the journey.
Common Load Shift Problems and What Fixes Them
Below is a simple planning tool you can use at the dock. It will not replace a load plan, but it does help teams move quickly from symptom to solution category.
| Problem | What Causes It | Best-Fit Solution Category |
|---|---|---|
| Side-to-side drift | Open lateral voids, loose loading pattern | Void fill solutions, dunnage air bags |
| End-to-end movement | Poor front or rear restraint, weak contact | Blocking and bracing, bulkheads, air bags |
| Leaning pallets | Uneven weight distribution, weak packaging, poor stacking | Corrugated/interior packaging, blocking and bracing |
| Product rub or abrasion | Inadequate separation, vibration over distance | Interior packaging, corrugated packaging, corner protection |
| Slip on smooth surfaces | Low friction at pallet or floor contact points | Anti-slip materials, better pallet interface, bracing |
| Moisture-related damage in containers | Condensation, long transit, humidity exposure | Desiccants, protective packaging, moisture-control support |
The details can seem complex at first, but you’ll soon learn that the pattern is straightforward.
When the issue is open space, start with gap control. When the issue is weak contact or unstable geometry, focus on blocking, bracing, and packaging integrity. When the issue is longer transit exposure, add supporting freight protection products instead of assuming one material can solve everything.

Planning Matters: Load Securement Starts Before the Dock
Thorough damage prevention happens before the loading ever begins. The best teams standardize how they measure voids, verify packaging condition, assign materials, and document placement.
This is where custom load plans matter. We help teams build a repeatable approach with load plans, on-site training, design and testing support, diagrams, and modality-specific guidance. That kind of work helps reduce variation across shifts, tighten up execution, and make load securement more consistent from one shipment to the next.
The goal is repeatability. When crews are working from a clear, proven approach, you reduce variation, lower damage risk, and make better results easier to repeat.
Checklist: Before Loading
Use this helpful checklist before the first unit goes in:
- Confirm shipment modality and expected movement profile
- Measure key voids, especially side gaps and end gaps
- Check pallet quality, package integrity, and stack stability
- Verify floor and contact surfaces are dry and free of debris
- Stage the right materials: dunnage air bags, void fill, bracing, anti-slip, desiccants
- Review placement points and loading sequence with the crew
- Make sure inflation tools, cutting tools, and other equipment are ready
- Pull the correct work instruction, photo standard, or load diagram if one exists
Checklist: Before Shipping Final Verification
Before release, do one more pass:
- Walk the full load and confirm all contact points are still tight
- Check air bag size, location, and inflation against the plan
- Confirm blocking and bracing is seated properly and has not shifted during loading
- Verify packaging damage did not occur during forklift handling
- Recheck trailer or container cleanliness and closure condition
- Confirm labels, seals, and any required shipment records are complete
- Capture photos if the lane, SKU, or loading pattern is new
- Escalate anything unusual before dispatch, not after arrival claims start showing up
Common Mistakes and How to Avoid Them
The most common errors are surprisingly consistent.
Using the wrong material for the size of the void
When a gap is too large for the product being used, the load is unstable. To prevent this, measure voids before loading and choose a solution that matches the actual space, not a rough guess.
Poor placement of securement materials
Even the right material can fail if it’s installed in the wrong location. If the contact point does not control the movement path, the load still has room to shift. Prevent this by defining placement points clearly and training crews to follow the same loading pattern every time.
Over-inflating dunnage air bags
More pressure does not automatically mean better securement. Over-inflation can stress packaging, reduce effectiveness, and hide underlying problems like poor load geometry or the wrong bag size, while under-inflation can allow the cargo to shift. The best approach is to use the correct bag for the application and inflate it according to the load plan and product guidelines.
Relying on airbags or void fill to fix a bad load pattern
Securement products work best when the load is built correctly in the first place. If weight is poorly distributed or contact between units is weak, adding more material will not solve the root issue. Start with a sound loading pattern, then use securement materials to reinforce it.
Ignoring packaging condition before loading
Damaged pallets, crushed cartons, or unstable stacks weaken the entire securement system before transit even begins. A quick packaging check before loading helps catch problems early, when they are still easy to correct.
Letting the process vary from shift to shift
When each crew loads the same lane a different way, results become hard to predict. The solution is standard work: load diagrams, photo references, lane-specific instructions, and updates whenever the product, pallet, destination, or modality changes.
When You Should Talk to a Load Securement Expert
When a load becomes harder to secure, or damage keeps coming back, it’s wise to bring in expert help. New lanes, new products, packaging changes, modality shifts, and repeated claims usually point to a gap in the current securement plan – and that’s not something you want to manage through guesswork, trial, and error.
Sunrise Manufacturing helps customers develop custom load plans, team training, and design support based on the real risks in the shipment, so teams can load with more confidence, consistency, and success.

FAQs
What are load securement solutions?
Load securement solutions are the materials and methods used to keep freight stable in transit. They usually include dunnage air bags, void fill solutions, blocking and bracing methods, corrugated packaging, and supporting freight protection products.
What is the fastest way to prevent load shift?
Start by eliminating open space and improving contact between load units. In many shipments, that means measuring voids correctly and using the right void fill or air bag solution before the load leaves the dock.
When should I use dunnage air bags vs void fill?
Use dunnage air bags when you need to fill appropriate voids and create controlled pressure between load units. Use void fill solutions when the application calls for more structural space-filling support, especially where repeatable gap control and lateral restraint are the priority.
What is blocking and bracing in a container?
Blocking and bracing is the method of restraining cargo so it cannot move excessively during transit. It can include panels, bulkheads, bracing elements, and supporting materials that keep the load tight and stable.
How does load securement change between intermodal and OTR?
Intermodal usually involves a broader movement profile because the load may see truck, terminal, and rail conditions. OTR tends to focus more on braking, cornering, and continuous road vibration, so the material mix and placement strategy can change.
How do I reduce transit damage risk?
Reduce transit damage risk by treating securement as a system: plan the load, choose the right products, place them correctly, and verify the final load before release. Standard work and crew training matter just as much as the materials themselves.
Do I need a custom load plan?
If you are launching a new lane, shipping a fragile or high-value product, changing packaging, or dealing with repeat damage, a custom load plan is always a wise decision. It gives your team a repeatable method instead of relying on memory and guesswork, and drastically eliminates risk of damage.
What are common load securement mistakes?
Common mistakes include oversized voids, poor material selection, weak contact between load units, over-inflation, and inconsistent loading methods between crews or shifts. Most are avoidable with better measurement, clearer work instructions, and final verification.
What are freight protection solutions?
Freight protection solutions are the broader set of products used to reduce damage during handling and transit. They include securement materials plus supporting items like corner board, slip sheets, stretch film, and moisture-control products.
Can one product solve every load securement problem?
No. Stable shipments use a combination of methods. Air bags, void fill, packaging, friction support, and bracing each solve different parts of the problem. Explore load securement solutions to find the best solution for your load.
