Edge and corner protection: Why damage starts at the corners of your pallet, and the protective packaging that stops it

During transit and handling, stretch wrap and strapping can concentrate pressure on carton edges, while forklifts, racking and stacking can create further risks of impact and compression. Without the right protection, minor damage to a single corner can compromise the stability of the entire load, leading to costly product losses, customer complaints and returns.

Edge and corner protection provides a simple but effective way to reduce these risks. By distributing pressure, reinforcing vulnerable edges and helping maintain pallet stability, the right protective packaging can make a real difference to how well your goods withstand the journey.

In this guide, Swiftpak explores why pallet damage so often starts at the corners, how edge and corner protectors help prevent it, and how to choose the right solution for your load. From comparing corrugated and plastic edge protectors to matching protection to your packaging requirements, discover how the right protective packaging can help keep your products safer from warehouse to delivery.

Why corners and edges take the damage

Pallet corners and edges are often the first points to suffer damage during storage, handling and transit. Even when a load is securely wrapped, pressure and impact can compromise the cartons and the stability of the pallet.

Common causes include:

• Strapping and stretch wrap pressure: Tight strapping and stretch wrap can concentrate force along carton edges, cutting into cardboard or crushing corners.
• Forklift and handling impacts: Corners are particularly vulnerable to knocks from forklifts, contact with racking and manoeuvring in tight loading bays.
• Weight from stacked loads: When pallets are stacked, much of the pressure passes through the corners. If one corner collapses, it can weaken the entire load.
• Damage during transit: Small amounts of damage can worsen as pallets move through the supply chain, resulting in damaged goods, customer complaints, returns and costly claims.

Without suitable protective packaging, these vulnerable areas can compromise both the outer cartons and the products inside. Edge guards and corner protectors help reinforce these weak points, distributing pressure more evenly and reducing the risk of damage throughout the journey.

What edge and corner protection actually does

Edge and corner protection helps reinforce the most vulnerable parts of a pallet, reducing the risk of damage during storage, handling and transit. By adding an extra layer of support, it helps keep cartons intact and loads secure throughout the supply chain.

Edge guards distribute the pressure created by stretch wrap and strapping across a wider surface area, preventing force from concentrating on individual carton edges. They also improve load rigidity and stacking strength, helping pallets maintain their shape under pressure.

Keeping the pallet square and stable allows stretch wrap and strapping to secure the load more effectively, reducing the risk of cartons shifting or collapsing during transit. Just as importantly, protective packaging helps preserve the appearance of outer cartons, keeping products and brand presentation in better condition when they reach your customers.

Corrugated vs plastic edge protectors: Choosing the right type

Choosing the right edge and corner protection depends on your load, handling requirements and how often the packaging will be used. Both corrugated and plastic protectors offer benefits, so it is important to match the material to your specific needs.

Corrugated and paper-based edge protectors

Corrugated and paper-based edge protectors are a cost-effective option for businesses looking to protect lighter loads during storage and transit. They help distribute pressure from strapping and stretch wrap, reducing the risk of crushed cartons and damaged edges. They are also recyclable, making them a practical choice for businesses looking to reduce packaging waste.

Plastic edge protectors

Plastic edge protectors offer greater durability and can often be reused, making them suitable for heavier loads, demanding handling environments and repeat-use applications. Their strength helps maintain load stability and provides reliable protection where pallets are frequently moved or stacked.

Open vs closed corner protection

The shape of your load also influences the type of protection you need. Open and closed corner protectors are available to suit different carton designs and pallet configurations. Choosing the right style helps ensure vulnerable edges are adequately covered and that the protection works effectively alongside your existing stretch wrap and strapping.

Matching protection to your load

Choosing the right edge and corner protection depends on the weight of your pallet, how it is secured and the conditions it will face during transit. Consider the following factors when selecting protective packaging:

• Load weight and stack height: Heavier pallets and taller stacks need stronger edge protection to withstand pressure and maintain stability.
• Wrapping and strapping methods: If your pallet is secured using stretch wrap, strapping or both, choose edge protectors that distribute pressure effectively and prevent damage to carton edges.
• Journey type: Pallets stored within a warehouse may need different protection from those travelling by road freight or being shipped for export, where handling and transit conditions can be more demanding.
• Product value and fragility: High-value or fragile goods may require additional protection to minimise the risk of damage, returns and replacement costs.

By considering these factors, you can choose edge and corner protection that suits your load, reduces unnecessary damage and provides the right level of protection without overspending on packaging.
