When transporting huge bundles of heavy items over long distances, straps are often used to secure goods. Steel, Polypropylene, nylon, and other materials are among the strapping packaging materials available. These strapping materials have unique characteristics that make them more suitable for specific transportation requirements.

Steel strapping has its benefits, but it also has some drawbacks. For example, if left untreated, it can corrode and discolour cargo. When it recoils from being cut owing to a tension release, it may inflict injury with its sharp edges. In this article, we will share the features and benefits of composite belts.

Understanding Composite Strapping

A robust, non-metal, and safer strapping system would be composite strapping. As the name suggests, composite belts are engineered packaging load securement solutions that combine multiple materials into a single high-performance belt. During transportation, the polyester strapping belt can absorb shocks and impacts.

It has a high retained tension and is a robust and safe alternative to steel strapping. Made of parallel layers of untwisted, high-tenacity polyester yarns covered in Polypropylene (PP), the unique and patented manufacturing process for these yarns allows the container strap to achieve higher strength, lower elongation, and resistance to most chemical solvents, caustics, and acids.

Composite strapping is commonly used for goods that may expand, settle, or contract during transportation. Specially made for usage on rough environmental materials and sharp edges, the strap is optimised to secure the cargo. Composite polyester belts are frequently connected with a wire buckle, and the buckle closes when tension is applied to the strap. They require a hand tensioning tool and light cutters, making them quicker and more convenient than steel belts. For optimal results, pair composite belts with nitrated wire buckles.

Features of Composite Strapping

Polyester composite straps offer a range of attributes that make them an alternative to traditional steel belts in various industrial applications. These straps exhibit remarkable strength, matching that of steel belts while providing several additional advantages. The polyester composite strap’s lightweight material also helps reduce overall load weights.

Their high impact resistance is a standout feature, as they can efficiently absorb impact energy due to their unique properties, elasticity, and ability to recover after deformation. This quality ensures that polyester composite straps maintain their tension and load-bearing capacity even under rigorous conditions, reducing the risk of cargo damage during transport.

Another notable advantage is their ability to retain tension. With high tensile strength ranging from 0.5 to 8.5 tons, these straps can readily replace standard steel belts and other strapping materials, offering a cost-effective solution. It incurs lower tool expenses, experiences minimal wear, and requires low maintenance, making it an economical choice for packaging needs.

Additionally, polyester composite straps are non-abrasive, safeguarding the surface of products from scratches and damage, which is particularly crucial for delicate or painted items. These straps are corrosion-free, eliminating concerns about splicing, sticking, rusting, or rotting that can plague steel alternatives. Their high UV resistance makes them suitable for long-term outdoor storage, and their Polypropylene coating enhances their durability, making them compatible with chemical goods.

Ultimately, the versatility of polyester composite straps makes them an attractive choice for a wide range of industries, as they excel in re-tensioning, shock absorption, and torsion resistance. Whether in manufacturing, shipping, or storage, these straps offer a reliable and cost-efficient strapping solution, contributing to the safety and security of goods during transportation.

Safety and Environmental Benefits

Polyester has minimal sharp edges compared to steel strapping, making it safer for users. The dull edges of polyester strapping are gentler on hands and forklift tires, preventing cuts and damage. Polyester composite straps also don’t bounce dangerously when removed, reducing the risk of injury to workers and consignees.

Using polyester strapping also leads to reduced environmental impact. Polyester is produced from raw resin materials throughout manufacturing and is a recyclable material. Workers can gather the removed polyester strapping by bundling it and disposing it in the garbage or through closed-loop recycling programs once the strapping has been removed.

Uses of Strapping

  • Bundling items together for handling and shipment
  • Fastening items to pallets, skids, and crates
  • Bracing wooden boxes, crates, and corrugated boxes
  • Attaching items to flatcars and semi-trailers
  • Securing bricks, packed glass, and metal pieces in a unit load
  • Closing corrugated boxes and shipping containers
  • Securing coils of steel or paper

How to Choose the Right Composite Belt

Choosing the appropriate composite belt for a specific application is crucial to ensure optimal performance and longevity. Here are some key factors to consider when selecting composite belts and tips for ensuring compatibility with particular needs:

Material Compatibility: Evaluate the materials being transported or processed. Ensure that the composite belt is resistant to chemicals, oils, and other substances that may come into contact with it during operations. Different materials may require different levels of resistance.

Load Capacity: Determine the weight and size of the belt’s loads. Select a composite belt with the appropriate load-bearing capacity to avoid premature wear and tear or potential failure under heavy loads.

Temperature Range: Consider the temperature conditions of the application. Some composite belts are designed to withstand extreme temperatures, making them suitable for high-heat or low-temperature environments. Ensure the chosen belt can operate within the desired temperature range.

Tension Requirements: Assess the tension requirements of the application. Composite belts come in various tensile strengths. Choosing one that matches the tension needs is vital to prevent overstretching or insufficient tension.

Belt Width and Length: Determine the required belt width and length to accommodate the specific conveyor system or processing equipment. Custom sizing may be necessary to ensure a proper fit.

Application Type: Understand the nature of the application. Different industries and processes may require specific belt types. For example, a food processing conveyor may need a belt that meets food-grade standards, while a heavy manufacturing application may require a more robust and durable belt.

Environmental Conditions: Consider the conditions the belt will be exposed to, including moisture levels, dust, and potential exposure to UV radiation. Choose a composite belt that can withstand these conditions without degradation.

Cost and Budget: Determine the budget for the composite belt. While high-quality belts may have a higher upfront cost, they can offer significant cost savings over time due to their longevity and performance.

By carefully considering these factors and seeking advice when needed, make an informed decision and select the right composite belt that meets and exceeds the requirements of a specific application. This ensures smoother operations, improved efficiency, and reduced downtime in industrial or manufacturing processes.

Maintenance and Care

Adhering to maintenance guidelines and common practices prolongs the lifespan of composite belts and ensures their continued reliability in industrial or manufacturing operations. Regular care reduces maintenance costs and enhances overall productivity and efficiency.

Firstly, routine visual inspections of these belts to spot signs of wear, damage, or unusual wear patterns early on. Such early detection can effectively prevent costly breakdowns and the need for replacements down the line. Keeping the composite belts clean as it prevents contaminants from compromising their performance. Furthermore, regularly monitoring and adjusting belt tension with strapping tensioners as needed is critical, as over-tensioning can lead to premature wear. In contrast, insufficient tension may result in slippage and reduced efficiency.

It’s imperative to follow the manufacturer’s recommendations for tension levels. Lastly, ensuring that personnel handling the composite belts are adequately trained in proper usage, tensioning, and maintenance procedures is essential, as knowledgeable operators can proactively prevent avoidable issues, contributing to the belts’ extended lifespan and the overall efficiency of industrial or manufacturing operations.
