Polyester strapping - Technical information

Composition

Extruded thermoplastic polyester manufactured in an ISO 9001: 2008 Environment.

Tensile Strength

Polyester has a very high tensile strength, which combined with a low creep factor enables excellent retention of applied load. At the same time ease of application and subsequent disposal generates a fast and highly efficient packaging process for either manual or automated use.

Joining Methods

Either by hand tool with metal buckles or seals, or friction welds, or heat sealed.

Breaking strength

The following is for example purposes only.
Many factors can affect the result:

FactorVariables
The type of package being strappedRigid/compressible
Sharp/round edges
Friction between items
The method of transportationInternal/export
Friction/heatseal
The seal strength of
Refer to tool/manufacturer for seal efficiency
Plastic buckle/metal seal
Palletised/loose
Safety factor1.5 - 2.0 of weight load

As a rule of thumb; a safety factor between 1.5 & 2.0 is desired.
Total load weight = 800 kg
6 straps each of 300 kg breakload = 1,800 kg
Seal efficiency 75% (Friction weld) = 1,350 kg
Safety factor = 1,350/800 = 1.7, between 1.5 and 2.0, so should be acceptable. Due to the many parameters that can affect the result, each unitisation can require different amounts and breaking strength of strapping.
The final specification is the responsibility of the applicator.
