About Strapping and Lashing

 

The difference between Strapping and Lashing:
 

  • Strapping:    strap up to 19 mm, for securing pallets and pallet loads
      
  • Lashing:       cargo securing strap with a width of 25 mm and up, for loading security

 

These two groups can be divided into 6 types:

                     PP (extruded polypropylene) - Strapping PET (extruded polyester) - Strapping                                 Hotmelt (glued polyester) - Strapping                           
    Composite (co-extruded polyester) - Strapping/Lashing Woven Polyester - Lashing                                           Woven Polypropylene - Lashing                                                      

 

 

Application Areas

     

Strapping/Lashing type

  Applications

  Closures

PP

(extruded polypropylene)

  • light-duty
  • strapping machines
  • strapping packages and boxes
  • melting (strapping machines)
  • plastic buckles
  • steel buckles
  • strapping seals

PET

(extruded polyester)

  • light-duty
  • light pallet loads
  • strapping packages and boxes
  • strapping seals

Hotmelt
(glued polyester)

  • cheap alternative
  • pallet loads where security is less important
  • strapping seals
  • steel buckles

Composite
(co-geëxtrudeerde polyester)

  • heavier pallet loads
  • lashing container loads
  • steel buckles

Woven Polyester

  • lashing of goods on trucks, ships, containers, on ship decks, in and on trains, in aircraft, etc.
  • stalen buckles
  • lashing frames

Woven Polypropylene

  • lashing of goods on trucks, ships, containers, on ship decks, in and on trains, in aircraft, etc.
  • safety belts in cars, airplanes, etc.
  • stalen buckles
  • lashing frames

 

Safety Standards

  Applicable in Europa

  Applicable in USA/Canada

Strapping:

  • none
  • none

Lashing:

  • there are no standards for lashing
  • however if the lashing is used for a ratchet tie down, the combination to meet the band/ratchet and 12195
  • the Breakingstrength of theis band must be at least 3 x the Load Capacity (LC)
  • Certification not required, no control, no penalties
  • ASTM 3950-D series
  • Breaking Strength (BS) of the band in a linear tensile strength test = minimum 3 x the Load Capacity (LC)
  • Breaking Strength combined with a Buckle = minimum 65% of the BS without buckle
  • Approval required where the approval number on the band must be printed for the traceability

 

The quality of band is among others determined by the tensile strength of the strapping/lashing:

According to the EN 12195 and ASTM 3950-D the Tensile Strength has to be determined with a series linear tensile testing of the band.

 


This continued with a series of tensile tests of the band combined with a buckle or frame.

 


In order to be able to come with a higher value customers is often the System Strength specified. This System Strength is only used as a selling point and is in fact the double value of the Linear Tensile Strength because the band is double.

The System Strength is not applicable in testing protocols.

 


Also at the System Strength is often specified a value for the band and then the band with a buckle or frame in system.
