Understanding Strapping in Freight: Securing Your Cargo with Ocean Cargo
What is Strapping in Freight? The Essential Guide
In the world of global logistics, the safe and secure transport of goods is paramount. One of the most fundamental yet critical methods for achieving this is through the use of "strapping." At its core, a strap is a band of metal, plastic, or other flexible material used to hold cargo or cases together, preventing movement, damage, and loss during transit. For businesses relying on efficient supply chains, understanding the role and application of strapping is key to successful freight forwarding.
Ocean Cargo, with over 25 years of expertise in navigating complex international shipping, recognises that proper cargo securing, including effective strapping, is non-negotiable. Whether your goods are travelling via sea freight, air freight, or road freight, the integrity of your shipment often hinges on these seemingly simple bands.
Why is Strapping So Important for Cargo Security?
The journey of cargo from origin to destination can be fraught with challenges: sudden stops, turbulent seas, air pockets, and rough roads. Without adequate securing, goods can shift, collide, and sustain significant damage. Strapping plays a vital role in mitigating these risks by:
- Unitising Loads: Bundling multiple smaller packages into a single, stable unit, making handling easier and reducing the risk of individual items being lost or separated.
- Stabilising Pallets: Securing boxes or items to a pallet, preventing them from toppling or shifting during loading, unloading, and transit.
- Reinforcing Packaging: Adding strength to cartons and crates, especially for heavy or irregularly shaped items, to prevent bursting or collapse.
- Preventing Pilferage: While not foolproof, strapping can act as a deterrent to opportunistic theft, as it requires effort to remove and reapply.
- Ensuring Safety: Preventing cargo from becoming a hazard to personnel during handling or to other cargo during transit.
Ocean Cargo's commitment to precision and reliability extends to advising clients on the best practices for cargo preparation, ensuring that every shipment meets the highest standards of safety and security.
Types of Strapping Materials and Their Applications
The choice of strapping material depends heavily on the cargo's weight, fragility, environmental conditions, and the specific transport mode. Here are the most common types:
Steel Strapping
Description: The strongest and most rigid strapping material, available in various widths and gauges.
Applications: Ideal for heavy-duty applications, such as securing large machinery, construction materials, timber, and metal coils. It's often used for rail and intermodal shipments where extreme forces are encountered.
Pros: High tensile strength, minimal stretch, excellent for rigid loads.
Cons: Can be sharp, prone to rust, heavier, and more expensive than plastic alternatives.
Polyester (PET) Strapping
Description: A strong plastic strapping that offers a good balance of strength and elasticity. It's often seen as a safer and more cost-effective alternative to steel for many applications.
Applications: Suitable for medium to heavy loads, including palletised goods, bricks, textiles, and some machinery. It's commonly used in sea freight to the USA and other long-haul routes where some give is beneficial.
Pros: High tensile strength, good elasticity (absorbs shock), rust-resistant, safer to handle than steel, recyclable.
Cons: Can lose tension over time in extreme heat, not as strong as steel for the heaviest loads.
Polypropylene (PP) Strapping
Description: The most common and economical plastic strapping. It's lightweight and flexible.
Applications: Best for light to medium-duty applications, such as bundling newspapers, securing cartons, and light palletising. Often used for domestic road freight and smaller consignments.
Pros: Cost-effective, lightweight, easy to handle, good elasticity for shock absorption.
Cons: Lower tensile strength, prone to stretching and losing tension, susceptible to UV degradation.
Woven and Composite Cord Strapping
Description: Made from high-strength polyester fibres, these offer a textile-like feel but with significant strength. Woven cord strapping is flexible, while composite strapping is encapsulated in polypropylene for added rigidity and moisture resistance.
Applications: Excellent for securing irregular loads, heavy machinery, and cargo that requires high break strength without the sharp edges of steel. Often used for project cargo, such as excavators and diggers to the UAE, where flexibility and strength are crucial.
Pros: High tensile strength, shock absorbent, safe to handle, rust-proof, can be re-tensioned.
Cons: Generally more expensive than PP or PET, requires specific tools for application.
The Strapping Process: Key Considerations for Effective Securing
Effective strapping isn't just about choosing the right material; it's also about proper application. Here are the critical steps and considerations:
- Load Preparation: Ensure the cargo is stacked evenly and stable on the pallet or within the container. Use corner protectors to prevent the strap from damaging the goods and to distribute tension more effectively.
- Strap Placement: Position straps strategically around the load, typically at regular intervals, to provide maximum stability. For palletised goods, straps should go around the entire load and the pallet itself.
- Tensioning: Apply appropriate tension to the strap. Too little tension means the load can shift; too much can damage the cargo or the strap itself. Manual or automatic tensioning tools are used for this.
- Sealing/Joining: Secure the ends of the strap. This can be done with metal seals (crimps), heat welding (for plastic straps), or buckles (for cord strapping). The seal must be strong enough to withstand the forces of transit.
- Edge Protection: Always use edge protectors (cardboard, plastic, or metal) under the strapping where it comes into contact with the cargo. This prevents the strap from cutting into the goods and also protects the strap from abrasion.
- Compliance: Adhere to relevant industry standards and regulations for cargo securing, such as those set by the International Maritime Organization (IMO) for sea freight or IATA for air freight.

Can I reuse strapping?
Generally, it is not recommended to reuse strapping, especially for critical applications. Strapping materials can weaken or become damaged after initial use, compromising their tensile strength and ability to secure loads effectively. For safety and cargo integrity, always use new strapping.
What's the difference between strapping and banding?
The terms "strapping" and "banding" are often used interchangeably in the freight industry. Both refer to the process of applying a flexible material band around cargo to secure it. There is no significant technical difference in their meaning or application.
How do I know which type of strapping to use for my cargo?
The best strapping type depends on several factors: the weight and nature of your cargo, its fragility, the mode of transport, and environmental conditions. For heavy, rigid loads, steel or polyester is often preferred. For lighter, more flexible loads, polypropylene may suffice. Ocean Cargo's experts can provide tailored advice based on your specific shipping requirements. Contact us for a consultation.
Are there regulations for cargo strapping?
Yes, there are various national and international regulations and guidelines for cargo securing, particularly for international shipping. These include standards set by organisations like the IMO (International Maritime Organization) for sea freight and IATA (International Air Transport Association) for air freight. Adhering to these is crucial for safety and to avoid delays or penalties. Ocean Cargo ensures all shipments comply with relevant standards.
