Description
Marlex® HHM TR-144 is a high molecular weight ethylene-hexene copolymer designed for blown-film extrusion. The grade provides a strong balance of toughness, durability, processability, stiffness, and tear performance.
It also offers good blending characteristics with other high molecular weight HDPE film resins, allowing film producers to adjust processing and finished-film performance according to application requirements.
Key Characteristics
Applications
- T-shirt and shopping bags
- Multi-wall liners
- Trash bags
- General blown-film packaging
Food-Contact Compliance
Manufacturer documentation lists this grade under FDA 21 CFR 177.1520(c) 3.2a and EU Regulation No. 10/2011. The latest food-contact declaration should be confirmed for the intended market and finished application.
