Everyday Usages of Plastic Strapping
Plastic strapping, also known as banding, is widely used in personal, commercial, and industrial environments for bundling and securing items. Here’s how it benefits different users:
- Warehouse & Logistics: Securing cartons on pallets, unitizing products, reinforcing boxes, or bundling similar items for easier handling and transit.
- Manufacturing: Bundling of building materials (lumber, pipes), bricks, and even heavy industrial goods.
- Retail & E-commerce: Maintaining package integrity during shipping, bundling multi-packs, and protecting goods in transit.
- Agriculture: Keeping bales, crates, and harvest containers tightly secured during storage and shipment.
- Distribution Centers: Speeding up high-throughput packaging lines, particularly when partnered with strapping machines.
- Trades & Light Industry: Portable kits allow small operations or construction sites to quickly bundle materials or secure shipments.
Benefits of Plastic Strapping
Plastic strapping offers several advantages over other methods of bundling and securing:
- Lightweight & Easy to Handle: Far less weight compared to steel strapping, reducing shipping costs and improving safety.
- Versatile Strength: Available in a range of strengths (from light to heavy-duty), allowing you to match strapping to your specific needs.
- Corrosion Resistant: Unlike steel, plastic won’t rust or discolor your products.
- Safe & User-Friendly: No sharp edges, lowering the risk of injury. Tools are simple, often requiring less force.
- Weather Resistance: PET and specialized PP strapping can withstand moisture and UV exposure for extended periods.
- Cost-Effective: Generally more affordable than steel strapping, with lower disposal costs.
- Customizable: Available in pre-cut lengths, multiple widths, and colors for easy identification or branding.
How to Choose the Right Plastic Strapping
Choosing the right strapping ensures that your packages arrive safely and efficiently. Here’s what to consider:
1. Identify Your Application
- Light Duty: Cartons, lightweight bundles, mail trays, or product grouping—choose polypropylene (PP) strapping.
- Medium Duty: Palletizing, heavier boxes, or repeated handling—use wider/higher strength PP or switch to polyester (PET) strapping.
- Heavy Duty: Securing large loads, bricks, lumber, or items stored outdoors—select PET or corded strapping.
2. Assess Load Weight and Stress
- Calculate the maximum weight and stress the strap will bear. Polyester strapping excels when long-term tension is required, whereas PP is best for lighter, lower-value loads.
- For loads that might settle or expand, PET’s reduced elongation and high retained tension is beneficial.
3. Manual vs. Machine Application
- Hand Grade: Best for manual applications with hand tools and lower volumes.
- Machine Grade: Required for strapping machines, ideal for high-speed, repetitive tasks in warehouses.
4. Closure Methods
- Heat Seals: Fast and strong, ideal for machine-grade strapping.
- Seals & Buckles: Simple application, best for hand-grade and corded strapping.
- Friction Weld: Used in battery-powered/combo hand tools for quick, reliable joints.
5. Environmental Conditions
- For short-term indoor use, standard PP is suitable.
- For outdoor storage or UV exposure, opt for black or UV-stable PET.
6. Strapping Size & Color
- Width/Thickness: Select based on load requirements—wider/thicker = stronger, but may require compatible tools.
- Color/Printing: For branding or identification, choose printed or colored strapping.
User Tips and Best Practices
1. Preparation and Safety
- Always wear gloves and safety glasses when tensioning or cutting strapping.
- Use edge protectors to prevent strapping from cutting into packages, especially with heavy or sharp-edged loads.
2. Securing Loads Properly
- Apply tension only up to the working range (about 1/3 of rated break strength).
- Do not overtension, as this can damage both strap and product.
3. Tool Selection
- Match your tools (tensioners, sealers, cutters) to your chosen strap type and width.
- Test new combinations of strapping and closures before full-scale use.
4. Machine Maintenance
- Keep strapping machines clean and free from dust/debris, especially with PP, which can create more dust.
- Regularly inspect and service your tools and machines for optimal performance.
5. Storage
- Store strapping rolls in a dry area protected from direct sunlight unless specifically UV-stable.
- Keep coils sealed to minimize dust accumulation and prevent tangling.
6. Environmental Responsibility
- Recycle used PET strapping where facilities exist.
- Consider strapping made with recycled content or bio-based plastics for sustainable operations.

FAQ
What is the difference between polypropylene (PP) and polyester (PET) strapping?
Polypropylene (PP) is lighter, has higher elongation, and is ideal for light to medium-duty bundling. Polyester (PET) is stronger, with less stretch, making it better for heavier loads and applications requiring long-term tension retention.
Can I use plastic strapping outdoors?
Yes. PET strapping and black or UV-stable PP can handle months of outdoor exposure. However, avoid prolonged direct sun on non-UV stabilized PP, as it may degrade within 30–90 days.
What tools are required to apply plastic strapping?
Hand strapping requires a tensioner and a sealer (with metal seals or buckles). Automatic or semi-automatic strapping machines are available for high-speed, large-scale use.
Is plastic strapping recyclable?
Polyester (PET) strapping is widely recyclable. Many suppliers offer recycled-content and bio-based options for sustainability. Polypropylene is also recyclable, though local facilities may vary.
How do I determine which strength of strapping to use?
Calculate the maximum package weight and stress during handling and transit. Choose a strapping with a break strength 2–3 times higher than your expected maximum load for safety.
Can plastic strapping damage my products?
Incorrectly applied strapping can damage edges or surfaces. Use edge protectors or cushioning for delicate or sharp-edged goods, and avoid excessive tension.
Are there colored or printed plastic straps for branding?
Yes. Both PP and PET are available in various colors and can be printed with company logos or information for identification and brand promotion.
What’s the difference between hand grade and machine grade strapping?
Hand grade is thicker and more flexible for manual use, while machine grade has tighter tolerances and uniform size, ensuring smooth feeding in automatic machines.
How do I safely cut plastic strapping?
Wear gloves and eye protection. Use a proper strapping cutter and always cut away from your body, keeping hands and face clear of recoil.
Can I replace steel strapping with plastic?
Often, yes. PET strapping now rivals steel in strength for many applications, with added benefits like safety, cost efficiency, and corrosion resistance. For extremely high-tension uses, consult with your supplier.
