PET strap, or polyester strapping, is a high-strength plastic strapping made from polyethylene terephthalate (PET) resin. The resin is extruded into a flat strap, then oriented and stretched to increase strength and reduce thickness, giving it high tensile strength and a property no other plastic strap matches: it recovers tension as a load settles and shifts, staying tight through the whole journey. With high resistance to UV, heat and cold, PET strap is the leading safe, cost-effective alternative to steel strapping for export and outdoor applications.
BENZ Packaging manufactures PET strap for the steel, stone, brick, tile, timber, glass, construction, battery and heavy-machinery industries, and for long-distance export where retained tension and weather resistance are essential. It is supplied in embossed and smooth finishes across a full range of widths and break strengths, for manual sealless tools, tensioners and fully automatic strapping systems.
Why PET strap replaces steel:
- Recovers tension as loads settle, keeping the load tight, something steel cannot do
- Safer to handle, no sharp edges and no dangerous spring-back on cutting
- Does not rust or stain cargo, ideal for bright metal, stone and finished goods
- One tonne of PET strap covers roughly the same length as six tonnes of steel, at a lower cost per metre
- High UV, heat and cold resistance for outdoor yards and ocean voyages
- Matches steel holding performance for most loads up to about 1,360 kg
- Can be tensioned up to around 50% more than PP strap of the same size
How to choose the right PET strap:
- Medium loads and cartons: 9 mm to 12 mm width
- Heavy pallets, timber and general export: 16 mm to 19 mm width
- Steel coils, stone, brick and the heaviest loads: 25 mm to 32 mm width
- Match the joint method (heat weld on automatic machines, friction weld on battery tools) to your equipment
Applications: steel coils and sheets, stone, brick and tiles, sawn timber and panels, glass, heavy pallets and machinery, battery modules, and long-distance export and ocean freight.
PET strap vs PP strap:
Choose PET strap for heavy loads, export and outdoor storage. Choose PP strap for light to medium loads where cost and flexibility matter more.
Frequently asked questions:
What is PET strap made of?
PET strap is made from polyethylene terephthalate (polyester) resin, extruded and then oriented and stretched to increase strength, giving it high tensile strength and excellent tension retention.
How much weight can PET strap hold?
Depending on width and thickness, PET strap holds roughly 150 kg to over 1,100 kg per strap. A 25 mm strap can hold around 900 kg and the widest grades exceed a tonne, which is why PET replaces steel on most heavy loads.
Is PET strap as strong as steel?
Steel has the highest ultimate break strength, but for most loads up to about 1,360 kg PET strap matches steel's holding performance while being safer, lighter and cheaper. Unlike steel, PET recovers tension as the load settles and does not rust or stain cargo.
What is the difference between PET and PP strap?
PET strap has higher tensile strength, the highest retained tension of any plastic strap, and strong UV, heat and cold resistance, suiting heavy loads, export and outdoor use. PP strap is lighter, more flexible and cheaper, best for light to medium loads and indoor or short-term use.
Why use PET strap instead of steel strapping?
PET strap does not rust or stain cargo, has no dangerous spring-back on cutting, recovers tension as loads shift, and offers far greater length per tonne than steel at lower cost, making it safer and more economical for most heavy loads.
Can PET strap be used for battery modules?
Yes. PET strap is widely used to strap battery modules because it manages cell expansion and holds stack integrity without the galvanic contact or edge-cut risk of steel strapping.
Is PET strap suitable for outdoor and export use?
Yes. PET strap has high UV, heat and cold resistance and retains tension over long periods, making it ideal for outdoor storage and long-distance export and ocean freight.
