Introduction
In the modern industrial packaging sector, polyester strapping is steadily replacing traditional steel straps. Industries such as manufacturing, logistics, warehousing, construction materials, and exports are shifting toward polyester straps due to their superior performance, safety, and cost efficiency.
Unlike steel straps, polyester strapping offers flexibility, shock absorption, and resistance to rust and environmental conditions. This makes it an ideal solution for heavy-duty packaging applications.
What is Polyester Strapping?
Polyester strapping is a high-strength packaging material made from PET (Polyethylene Terephthalate). It is designed to secure heavy loads such as steel coils, timber bundles, bricks, cartons, and machinery during transportation and storage.
With excellent elongation and elastic recovery properties, polyester strapping maintains tension even when the load settles, ensuring stability throughout transit.
Key Reasons Why Polyester Strapping Is Replacing Steel Straps
1. Superior Elasticity and Tension Retention
One of the biggest advantages of polyester strapping is its ability to stretch and recover.
- Elongation: 9–12%
- Elastic Return: Approx. 6%
- Maintains consistent tension
- Prevents load shifting
Steel straps are rigid and lose tension when loads shrink or settle. Polyester strapping adapts to load movement, maintaining secure packaging.
2. Rust-Free and Weather Resistant
Steel straps are prone to rust, especially in humid or coastal environments. Rust can damage packaged goods and reduce strap strength.
Polyester strapping is:
- Rust-free
- Stain-free
- Chemically inert
- UV stable
- Weather resistant
This makes it ideal for export packaging and outdoor storage.
3. Improved Safety for Workers
Safety is a major concern in heavy-duty packaging.
Steel straps:
- Have sharp edges
- Can cause serious injuries
- Whiplash dangerously when cut
Polyester strapping:
- Has no sharp edges
- Does not recoil dangerously
- Is lightweight and easy to handle
This significantly reduces workplace accidents.
4. Excellent Shock Absorption
During transportation, goods experience vibrations and sudden jerks. Polyester strapping performs well under shock loading and absorbs sudden force exerted during transit.
Steel straps are rigid and may snap under impact, whereas polyester strapping distributes the load evenly.
5. Cost-Effective and Lightweight
Polyester strapping is lighter than steel, reducing overall shipment weight and transportation costs. It is also economical in large-scale packaging operations.
Industries benefit from:
- Lower material costs
- Reduced product damage
- Long-term durability
- Better aesthetics
6. Wide Range of Sizes and Customization
Polyester strapping is available in:
- Widths: 12 mm, 15 mm, 19 mm
- Thickness: 0.7 mm to 1.27 mm
- Core Size: 203 mm / 406 mm
- Surface Finish: Embossed or Plain
- Standard Color: Green (other colors available)
- Printing option available
Custom sizes can be manufactured as per customer requirements.
7. Easy Application with Manual and Battery Tools
Manual Strapping Tool Set
- Includes tensioner and sealer
- Economical option
- Easy to handle
- Suitable for moderate usage
Battery Operated Tools
- Faster operation
- Suitable for high-volume packaging
Metal clips are available in open and closed types for secure fastening.
