PET straps are increasingly used for reinforcing carton packaging, facilitating their handling and transport. Lotryl® T copolymer is a new modifier which improves the impact splitting properties and stretchability of these PET straps.

PET strapping is widely used to replace steel wrapping for the storage and transportation of goods. They keep materials stable while in transit, and withstand temperature differences and exposure to sunlight.

Thanks to Arkema's production process that increases melting temperature and improves tensile strengh, Lotryl® T copolymers can be used as an effective modifier for PET strap applications.

Lotryl® T copolymer can be compounded using conventional polyester processing temperatures due to its excellent thermal stability (> 250°C).

In addition to enhancing the impact splitting resistance of PET straps, Lotryl® T copolymer provides an excellent holding force and improves the stretchability without limiting the friction welding process. Furthermore, just 2-5% of Lotryl® T is needed to achieve these results.
