Our premium PET and PP strapping can be used with either manual devices or on fully automated machines. All common strap dimensions we can usually deliver directly. Most of our PET quality strap type are manufactured in our modern production facilities in Germany near Hamburg. Further dimensions we are happy to produce according to your individual requirements.
With many manufacturers equipping their strapping machines with a range of core retainers, our product program of course also includes different core diameters.
Additionally, LINDER as a strapping producer offers you the special option of getting your PET strapping custom printed from orders of just a single pallet. In addition to providing advertising space, personalized printing also functions as a packaging seal. With increasingly demanding security requirements this can be a significant advantage.
PP-Polypropylene-Strapping, also called PP strap, is the simplest type of strapping among plastic strapping bands and is mostly applied with automatic strapping machines. Most automatic strapping machines offer a core holder for core dimensions of 200 mm. Strapex machines use 280 mm. Moreover, PP strap is also available on a 406 mm core, which are partly used for fully automatic pallet-strapping devices, but are especially used with manual strapping devices. In that process the large roll of PP strap is set onto the dispenser cart and the strap is normally applied with battery-powered strapping devices.
PP strap is also available in dispenser boxes; there are 1,000m in one dispenser which are used with plastic buckles which eliminates the need for a strapping device.
With regard to PP strap, we can distinguish between embossed and smooth design. Some strapping machines require smooth strap, though. Signode calls their strap “Dylastic Band”.
LINDER PET strapping in comparison to the PP strapping distinguishes itself by clearly higher strength. Further the stretch is lower (higher elongation) and the stiffness is higher - even under hot, humid conditions – the latter contributes to the fact that PET strapping, also called polyester strapping or polyethylenterephthalat strapping can be processed more easily, because it can be pushed under a pallet quickly.
PET strap comes on a 406 mm core. It is green and available in strapping ranges of 9 - 25 mm. With a 19x1.27 mm PET-Strapping band, for example, a tensile strength of approx. 1,100 kg per cycle can be achieved. Hence, PET strap is especially interesting as an alternative to steel strapping. It has the clear advantage that it can be used much more efficiently than for example polyester-yarn-strapping. PET-Strapping does not need to be threaded into metal seals but can easily be tensioned and welded with the help of a battery-powered strapping device. Thanks to a so-called friction-lock, the two ends of the PET-strapping are rubbed and pressed against each other at the same time welding them together that way.
Other than band width and thickness we distinguish between smooth and embossed PET strapping: Embossed means that the strapping gets an embossment, along which the strength is measured. This is how the nominal band thickness is reached and yet material is saved which allows for a lower price but also results in a lesser tensile strength as compared to the smooth strapping.
