Concrete blocks

Polyester strap retains high tension and maintains solidity to the pack. The excellent qualities of polyester are:

No problems on edge of packs due to high splitting resistance and no corner damage.
Excellent quality even at temperatures over 120°C.
The high tensile strength is double towards PP strap ensuring a fast and safe movement of the pack.
High resistance against weather conditions and UV rays ensures tension is retained over a long time period outdoors
