- Lightweight Nature: Plastic strapping is significantly lighter than steel strapping, reducing overall package weight and making it easier to handle. This can be especially beneficial in reducing shipping costs and minimising the physical strain on workers.
- Variety of Strengths: While not as strong as steel, plastic strapping comes in various grades, each designed to meet different load requirements. High-strength polyester strapping, for example, can be an excellent alternative for moderately heavy loads.
Typical uses of plastic strapping:
- Palletising Consumer Goods: Frequently used for bundling lighter items such as boxed products, consumer goods, and textiles. Its flexibility ensures that products are tightly secured without damage.
- Securing Paper and Print Materials: Ideal for bundling newspapers, magazines, and other paper products, where the risk of damage from overly tight strapping needs to be minimized.
- Logistics and Distribution: In distribution centres, plastic strapping is widely used for securing items onto pallets for internal movement and short-haul transportation. Its ease of use and efficiency make it a popular choice in these settings.
Plastic strapping’s flexibility, lightweight nature, and range of strengths make it a versatile choice for securing less heavy loads. Its suitability for a diverse array of applications ensures that it remains a popular option in many sectors of the packaging and logistics industry.
Comparing the Strength and Durability of Plastic and Steel Strapping
When selecting the right strapping material for packaging and logistics, understanding the differences in tensile strength and durability between steel and plastic strapping is crucial. Each material is uniquely suited to different types of loads based on these characteristics.
Tensile Strength Comparison:
– Steel Strapping: Known for its exceptional tensile strength, steel strapping is capable of securing extremely heavy and bulky items. It is less likely to stretch or break under tension, making it ideal for loads that require robust and rigid support.
– Plastic Strapping: While plastic strapping offers lower tensile strength compared to steel, it provides adequate strength for lighter loads. Its ability to stretch slightly makes it ideal for loads that may compress or settle, such as pallets of boxed goods.
Durability Aspects:
– Steel Strapping: Highly durable, steel strapping can withstand harsh environmental conditions, including exposure to UV light, moisture, and extreme temperatures. It is less prone to wear and tear over time, maintaining its strength for long-term or rough transportation.
– Plastic Strapping: Plastic strapping is less durable in extreme environmental conditions but offers sufficient durability for indoor storage and shorter transit periods. Its resilience against corrosion makes it suitable for certain applications where steel might be less ideal.
Suitability for Different Loads:
– Steel Strapping: Best suited for very heavy, rigid, or high-value loads, such as construction materials, heavy machinery, and metal products. Its strength ensures these loads remain immovable and secure during transportation.
– Plastic Strapping: Ideal for lighter, more uniform loads, such as consumer goods, palletised boxes, and paper products. It provides a secure hold while protecting the goods from damage due to over-tightening.
Your choice between the two strapping options should largely be made based on the specific requirements of the load in question.
Cost Considerations of Plastic and Steel Strapping
Evaluating the cost-effectiveness of strapping materials is a critical aspect – both steel and plastic strapping have different cost implications in terms of initial investment and long-term savings.
Initial Costs:
– Steel Strapping: Generally, steel strapping is more expensive in terms of initial cost compared to plastic strapping. This is due to the material’s strength and durability. The tools required for steel strapping (tensioners, sealers, cutters) are also typically more robust and expensive.
– Plastic Strapping: Plastic strapping offers a more budget-friendly initial investment. The material itself is less expensive, and the tools for plastic strapping are often cheaper and simpler than those used for steel strapping.
Long-Term Savings and Efficiency:
– Steel Strapping: While the upfront cost is higher, steel strapping can be more cost-effective in the long run for certain applications, especially where high strength and durability are required. Its ability to secure heavy loads reduces the risk of damage and loss, which can translate to significant savings.
