The transition from steel to composite cord strapping has been driven by several key advantages that the latter offers. These benefits are not only operational but also contribute to safety and cost-effectiveness in shipping and logistics.
Safety Considerations
One of the primary concerns with steel strapping is the risk of injury during handling. Steel bands are prone to sharp edges and can snap under tension, posing hazards to workers. Composite cord strapping, being non-metallic, eliminates these risks. Its soft and flexible nature reduces the likelihood of cuts or puncture wounds. Additionally, in the event of a strap failure, the composite cord does not recoil with the same force as steel, minimizing potential accidents.
Cost Efficiency
From a financial perspective, composite cord strapping offers significant savings. It is lighter than steel, reducing shipping weights and associated costs. The ease of handling and application can lead to labor savings, as workers can secure loads more quickly and with less effort. Moreover, equipment used for applying composite strapping is typically less expensive and requires less maintenance compared to steel strapping tools.
Environmental Impact
In today's eco-conscious market, the environmental impact of materials is a critical factor. Composite cord strapping is recyclable and contributes to waste reduction initiatives. Its production consumes less energy compared to steel manufacturing, resulting in a smaller carbon footprint. Companies seeking sustainable practices favor composite cord strapping for its alignment with environmental goals.
