PET strapping
for steel coils and bundles.
Connect the strap specification with the dimensions, contact points and equipment used for the load.
Explore the applicationA load. A line.
A specification.
A useful specification connects the load with material requirements and packaging equipment. Start with your application, then identify the dimensions, handling conditions and information to review.
Discuss strap dimensions, weight per meter, breaking strength, elongation and coil configuration together, with the actual application in view.
Steel
Heavy loads demand a balanced response.
Coil stability depends on sustained tension, resistance to splitting and the way the strap meets every contact edge.
01Sustained load & tension lossLoosening & layer movementMolecular integrity & stabilization
Continuous loading can accelerate creep and stress relaxation when molecular integrity and orientation are insufficiently stabilized.
Declining restraint can cause rework, handling delays and cargo-loss exposure.
Controlled drying and melt processing preserve molecular integrity; multi-stage drawing and thermal stabilization develop a stable load-bearing structure.
02Longitudinal splittingRapid loss of strap sectionMelt integrity & balanced orientation
Internal defects or excessive longitudinal orientation can allow small edge damage to propagate along the strap.
A small crack can develop into a full-length split, interrupting a shipment or requiring re-securing.
Filtration, melt homogenization and controlled draw ratios address crack-initiation defects while balancing longitudinal strength with transverse toughness.
03Sharp-edge stress concentrationCorner cracking & interruptionPrecision profile & toughness control
A small coil-edge radius creates localized bending and tensile strain. Strap properties alone do not replace suitable package protection.
Local failure can interrupt handling and require the package to be secured again.
Metering and finishing stabilize the cross-section; controlled orientation preserves usable strain tolerance. Review contact protection and the complete securing system.
Application engineering considerations from Newton. Confirm strap properties, joint performance, contact protection and equipment settings through trials with the actual package and handling conditions. No measured customer result is asserted here.

For steel coils and bundles, evaluate PET against actual contact edges, load geometry, temperature and joint requirements before considering a material change.
Edges and load geometry
Record coil orientation, strap path, bearing points and protective materials. Review whether contact conditions could damage the proposed strap. A nominal force value alone cannot establish suitability.
Temperature and joining
Identify the actual temperature at strapping, storage and handling. Use the grade and equipment operating limits supplied for review. Record the joining method and relevant joint-test results.
Acceptance criteria
Agree how strap position, protection, package condition and joint performance will be assessed through representative handling. Where PET is unsuitable, retain the existing approved system until a reviewed alternative is available.
Product family and grade suitability require an application review; no customer outcome or equipment approval is asserted here.
