Polyester composite strap, also known as polyester cord strap or woven polyester strapping, is a type of packaging material used for securing and bundling heavy loads during transportation and shipping. It is a high-strength and durable alternative to traditional steel or plastic strapping.

Here are some key features and considerations of polyester composite strap:

1. Material: Polyester composite strap is made from high-tenacity polyester yarns that are woven or braided together to form a strong and flexible strap. The polyester material provides excellent strength, resistance to elongation, and durability.

2. Strength and Tension: Polyester composite strap offers high tensile strength comparable to steel strapping, making it suitable for securing heavy loads. It has a high breaking strength and can withstand significant tension without breaking or stretching.

3. Lightweight: Compared to steel strapping, polyester composite strap is lightweight, making it easier to handle and reducing the overall weight of the packaged goods. This can help in reducing shipping costs.

4. Safety: Polyester composite strap is designed to have low recoil and minimal risk of snapping back when cut. It offers safety advantages over steel strapping, which can pose hazards when under high tension or if it breaks.

5. Weather Resistance: Polyester composite strap is resistant to weather conditions, including moisture, UV radiation, and temperature fluctuations. This makes it suitable for outdoor applications or goods that may be exposed to varying environmental conditions.

6. Elasticity and Shock Absorption: Polyester composite strap has a degree of elasticity, allowing it to absorb shocks and impacts during transportation. This helps to protect the packaged goods from damage and provides additional security during handling.

7. Easy Handling and Installation: Polyester composite strap can be easily tensioned and secured using manual or pneumatic tensioning tools and buckles or seals. It is user-friendly and does not require specialized equipment for installation.

8. Corrosion-Free: Unlike steel strapping, polyester composite strap is corrosion-free, which eliminates the risk of rust stains or corrosion-related damage to the packaged goods.

Polyester composite strap is commonly used in industries such as logistics, construction, timber, and metalworking. It is suitable for securing a wide range of heavy or irregularly shaped items, including pallets, lumber, pipes, machinery, and bricks.

It is important to select the appropriate width, thickness, and break strength of polyester composite strap based on the specific application and load requirements. The strapping should be properly tensioned and secured to ensure effective load containment.

Polyester composite strap can be sourced from packaging suppliers or strapping manufacturers. It is available in different widths, thicknesses, and lengths to accommodate various packaging needs.

Overall, polyester composite strap provides a reliable and cost-effective solution for securing heavy loads. Its high strength, flexibility, and resistance to weather and corrosion make it an excellent choice for securing and bundling goods during transportation and shipping.
