Imagine the dreaded moment you draw the curtains of your arctic back and see the load has shifted. Multiple items are destroyed and you clutch your forehead knowing the chaos in front of you is going to result in returns, claims and a restart of the process to replace them.
All that hassle naturally eats into your margins, which means it’s not just time you’re losing, but money too. Not to mention the environmental impact from rewrapping and repeating the transit process.
In this article, we’ll explore some practical ways to enhance your load stability so that you don’t need to put yourself in this hypothetical situation. We’ll look at new materials, smarter machinery, and best practices. In short, we’ll show you how to save money while ensuring that your shipments always arrive in great shape.
So, let’s get started…
Understanding Load Stability
What is Load Stability?
Load stability refers to the ability of a pallet or any other unit load to maintain its shape and alignment from the moment it’s wrapped to the time it’s finally delivered. If your load is unstable, it can shift or even collapse en route, resulting in product damage, potential health and safety hazards, and, of course, additional costs.
Why is it Important?
Safety and Compliance Unstable loads can lead to accidents, either in the warehouse or on the road. Apart from the obvious human cost, these incidents can result in hefty legal fees or damage to your reputation.
Cost Efficiency A stable load means fewer damaged goods, reduced returns, and less wasted film. These savings quickly add up, making your packaging process far more economical.
Customer Satisfaction No one wants to receive products in a battered state. Maintaining load stability helps ensure that everything arrives exactly how you intended.
The True Cost of Poor Load Stability
Direct Costs
Excessive Stretch Film Usage Wrapping and rewrapping can quickly deplete your stock. If your load isn’t stable the first time, you can easily end up doubling your film usage.
Damaged Products Broken or spoiled items need replacing, and you might end up paying for returns, refunds, or disposal fees.
Indirect Costs
Labour Inefficiencies Reworking loads and cleaning up spills consumes valuable staff time that could be spent on more productive tasks.
Increased Insurance Premiums Frequent damage claims signal a higher risk to insurers, potentially driving your premiums up.
Reputational Damage Late or damaged deliveries can sour relationships with customers and partners, leading to lost business in the long run.
Advanced Load Stability Innovations
Next-Generation Stretch Films
Multi-layer Films
Modern films often feature multiple layers that provide enhanced puncture resistance and load stability. Because these films can be thinner yet stronger, you use less material overall, saving on costs.
Pre-Stretch Technology
Pre-stretch systems are becoming a game-changer. These machines stretch the film before it’s applied to the pallet, meaning you can cover more surface area with less film. The tension is also more consistent, which leads to tighter wrapping and better load stability, all while using fewer metres of film.
Smart Wrapping Equipment
Innovations in automated stretch wrapping have moved far beyond the old “press a button and hope for the best” approach. Some of the latest machines can:
Adjust tension mid-wrap to suit the load shape and size.
Detect film breaks or insufficient film application, then automatically correct any issues.
Monitor film consumption in real time, giving you valuable data to refine your process.
Innovative Palletising Methods
Sometimes, the key to improving load stability isn’t just about the film itself. By integrating corner boards, or slip sheets, you can reinforce your loads and reduce the film needed to keep everything stable. Likewise, automated palletising systems can sort and stack products in ways that distribute weight evenly, ensuring a more stable base from the get-go.
Practical Strategies to Reduce Packaging Expenses
Conduct a Load Stability Audit
A thorough load stability audit is the critical first step in optimising your packaging process. Our load stability experts will come on site to evaluate and test your current wrapping setup, measuring the load stability you’re achieving, the cost per pallet wrapped, your plastic/CO₂ consumption per pallet, and the performance of your machinery.
Next, we’ll test our Shield films under the same conditions to compare and contrast results.
Using our advanced testing equipment, we collect accurate data across the entire pallet—rather than focusing on just one spot—so we can pinpoint exactly where improvements can be made.
Based on our findings, our specialists will adjust your existing equipment to maximise the film’s performance, or recommend replacement or alternative machinery if there’s a clear opportunity for greater efficiency.
Optimise Stretch Film Application
Standard Operating Procedures (SOPs) are invaluable. Document the best ways to wrap specific loads, indicating:
Tension Settings: Ensure machines are calibrated for the correct tension, minimising tears and ensuring stable wraps.
Number of Wraps: Different products may require more or fewer wraps depending on weight and fragility.
Wrap Patterns: A bottom-to-top spiral might work best in certain cases, whereas others call for cross-wrapping or roping for extra strength.
Be sure to train your staff thoroughly. Proper technique can drastically reduce the need for excessive or repeated wrapping.
Embrace Data Analytics
Data analytics isn’t just about collecting numbers—it’s about gaining actionable insights that help you refine your packaging and wrapping processes. By keeping track of crucial metrics such as film usage per pallet, break frequency, and load failures, you can pinpoint inefficiencies and continuously optimise your operations. Automated wrappers and warehouse management systems (WMS) are excellent starting points for gathering and evaluating this data.
For an even more in-depth analysis, our new Load Stability Testing Centre takes data-driven insights to the next level. Equipped with state-of-the-art technology, the centre boasts an acceleration bench and a tilt vibration bench, both of which simulate real-world transport conditions to measure the resilience and security of loads under stress. We also have several turntable wrappers, an automated line, and a robot wrapper on site, allowing us to evaluate different loading techniques and wrapping strategies in both manual and automated environments. By identifying potential weaknesses and testing practical solutions, we help businesses reduce damage, cut costs, and enhance the overall stability of their loads.
Our goal is to provide you with comprehensive, precise data that drives tangible improvements in your packaging operations. With nearly three decades of expertise and an unwavering commitment to innovation, we strive to be your ultimate destination for load stability testing. By partnering with our advanced facility, you’ll be empowered to make informed decisions that improve supply chain performance, reduce waste, and keep your loads secure at every step of the journey.
Conclusion
Investing in modern load stability techniques does more than just reduce the amount of stretch film you use. It also improves safety, boosts staff productivity, and enhances your company’s reputation by delivering products in pristine condition. Whether you start with a simple load stability audit or dive straight into advanced pre-stretch technology, every improvement you make today helps ensure a more profitable and efficient tomorrow.
The bottom line? Load stability shouldn’t be an afterthought. By following best practices, partnering with the right suppliers, and embracing new materials and machines, you can trim your packaging budget while delivering better results. That’s a win for your team, your customers, and your profitability.
