Eltex® Superstress™ CAP508S3

Eltex® Superstress™ CAP508S3 is a High Density Polyethylene copolymer manufactured by INEOS Olefins & Polymers Europe using its proprietary supported catalyst & process, particularly intended for the injection and compression moulding of screw caps for the packaging of beverages. It is especially suited for applications requiring excellent stress cracking resistance and enhanced processability. Thanks to high purity and excellent organoleptic properties it is well suited for packaging in direct contact with beverages and sensitive food.

Typical applications

• Injection Moulding and Compression Moulding of Caps & Closures for the packaging of sparkling water and carbonated soft drinks; especially in reduced weight cap designs

• Injection Moulding of thin wall packaging, especially for the food industry

Benefits and Features

• Very good processability

• High stress cracking resistance

• Excellent quality controlled organoleptic properties

• Grade containing a medium effective Slip Agent to reduce the friction at application and opening of caps.

Note : Exposure to direct sunlight has to be avoided as the slip agent is light sensitive and its degradation can give off-taste to the beverage.
