Heavy Duty Corded Polyester Strapping

-- Steady & Reliable Manufacturer --

Product Overview

Heavy duty corded polyester strapping is manufactured by bonding high-tenacity parallel polyester filaments with a thermoplastic polymer coating. Designed as a non-metallic replacement for steel strapping, corded polyester strap absorbs sharp shock impacts during transport through elastic elongation and recovery, preventing strap snapping on shifting heavy freight loads.

The flexible textile structure eliminates sharp steel edges, protecting operator hands, vehicle tires, and coated cargo surfaces from cutting or rust staining.

Factory Extrusion & Testing Standards

Zhejiang Geruite Packaging Materials Co., Ltd. produces PP strapping, PET plastic strapping, corded polyester strapping, PE stretch films, and industrial tapes in Zhejiang Province. Geruite operates continuous filament extrusion and coating lines engineered for heavy industrial load containment.

Every batch of corded polyester strapping undergoes tensile break load testing, joint efficiency verification with steel buckles, and elongation analysis under sustained tension.

Application Fields

  • Lumber & Timber Bundling: Securing raw logs, pressure-treated lumber, and plywood packs in outdoor storage yards.
  • Machinery & Steel Freight: Securing heavy industrial equipment, steel pipes, and aluminum extrusions onto flatbed trailers and sea containers.
  • Stone & Glass Unitization: Strapping marble slabs, concrete blocks, and architectural glass racks.

Technical & Operational Advantages

Corded polyester strapping provides specific performance advantages over rigid steel band:

  • Shock Absorption Memory: Absorbs dynamic transit shocks without permanent elongation or tension loss when cargo settles.
  • Non-Corrosive Safety: Will not rust or stain timber or stone surfaces when exposed to outdoor weather.
  • Re-Tensioning Capability: Can be re-tightened using manual tensioners if cargo shrinks during long ocean transit.
  • Q: How does corded polyester strapping fasten without heat welding?
  • A: It uses galvanized or phosphate-coated steel wire buckles; a hand tensioner pulls the strap tight, causing the buckle prongs to lock the textile fibers securely.
  • Q: Can corded polyester strap replace 3/4 inch steel strapping?
  • A: Yes, 19mm or 25mm heavy-duty corded polyester strap matches the system breaking load of 3/4 inch steel banding while absorbing higher shock energy.
  • Q: Does corded polyester strapping require heavy pneumatic tools?
  • A: No, lightweight manual ratchet tensioners and wire buckles are sufficient for manual tensioning in open yards or container loading.

Material Selection Guide

For light pallet bundling under 500kg, select 13mm or 16mm corded strap with 350kg-550kg breaking strength. For heavy lumber packs, steel pipes, or machinery container lashing exceeding 1500kg, specify 25mm or 32mm heavy duty corded polyester strap paired with 3.5mm thick phosphate wire buckles.
