If you’re in the business of shipping, storing, or transporting goods, chances are you’ve faced the challenge of damaged corners or crushed packaging at some point. Whether it’s a pallet of cartons or a fragile piece of furniture, keeping those edges intact is crucial — and that’s exactly where edge protectors come in.
But when, exactly, do you need them? And how do you choose the right type for the job — be it plastic corner protectors, cardboard edge protectors, or something more heavy-duty? Let’s unpack everything you need to know.
What Are Edge Protectors?
Edge protectors are simple, low-cost packaging accessories that do one very important job — protect the vulnerable corners and edges of your goods. Whether you’re shipping across the country or stacking pallets in a warehouse, edge protection helps maintain the shape, structure, and integrity of your items.
They’re usually made from materials like plastic corner guards or cardboard corner protector strips, and they come in different lengths, thicknesses, and profiles depending on the specific need.
Why Edge Protection Matters
Edges and corners are the first to take a hit when something gets bumped, dropped, or strapped too tightly. Without the right protection, even small dents or compression can lead to:
- Product damage or deformation
- Crushed packaging that weakens stacking stability
- Complaints or returns from unhappy customers
- Increased costs due to product replacements
Edge protectors act like armour for your packages — they absorb the pressure, spread the load, and keep your goods safe and stable.
When Do You Need Edge Protectors?
You might be surprised just how many situations call for edge protectors. Here are some of the most common (and often overlooked) scenarios where these packaging essentials make a real difference.
1. Pallet Strapping and Wrapping
If you use tensioned strapping (like steel or PET strapping) to secure goods on a pallet, there’s a high risk of crushing the outer boxes. That’s where plastic corner protectors shine. They spread the load of the strap, preventing cuts or dents in cardboard and soft packaging.
Tip: Pair your straps with plastic corner guards to ensure tight, secure loads without risking edge damage.
2. Stacking Heavy Pallets
When you stack multiple pallets, the weight of the upper layers can damage the packaging below. Using cardboard edge protectors reinforces the load, keeping boxes in shape and preventing bulging or collapsing edges.
This is especially useful in warehouses with limited space where vertical stacking is a must.
3. Fragile or High-Value Goods
Delicate items like furniture, glass panels, electronics, or finished wood pieces are particularly vulnerable during transit. Plastic corner guards provide a shock-absorbing layer that protects from knocks, drops, and tight spaces — think loading docks, forklift manoeuvres, or bumpy roads.
4. Export Shipments
Long-haul and international shipments often involve multiple touchpoints — handling, transfers, repacking, and sometimes harsh storage conditions. Adding cardboard corner protectors helps safeguard your goods from edge damage during the journey, ensuring they arrive in perfect condition.
5. Retail and Display-Ready Packaging
If you’re delivering directly to retail outlets or using branded boxes that double as display units, appearance matters. Damaged corners can hurt your product presentation and brand image. A simple edge protector helps maintain crisp corners, so your packaging looks as good on the shelf as it did at dispatch.
6. Stretch-Wrapping Bulk Loads
Stretch-wrap film is great for holding pallets together — but when pulled tightly, it can compress the boxes underneath. That tension can warp packaging or cause tearing. Using plastic corner protectors underneath the wrap helps distribute the pressure evenly and protects your load without compromising stability.
Choosing the Right Edge Protector
Not all edge protectors are created equal. The material and design you choose should match the product and purpose:
- Cardboard edge protectors: Cost-effective, recyclable, and great for general use on boxed goods and light to medium loads.
- Plastic corner guards: More durable and resistant to moisture — ideal for outdoor storage, export shipments, or heavy-duty applications.
- Custom sizes and profiles: Some products may require longer or wider protectors for full coverage. Look for options tailored to your needs.
Bonus Tip: Combine With Other Load Restraints
Edge protectors work best when they’re part of a full load restraint system. That includes dunnage bags, strapping, stretch wrap, and even anti-slip mats. For example, pairing edge protectors with portable dunnage bag inflators ensures your entire load is secure, stable, and protected from all sides — not just the edges.
Final Thoughts
So, when do you need edge protectors? In short — any time you care about protecting your cargo, preserving packaging, and keeping your operations running smoothly. They’re simple, effective, and save you from the costly consequences of damage.
