Titanex HF7000 is a high‑density polyethylene resin for tubular film extrusion, FDA‑approved for food contact.
Titanex HF7000 is a high‑density polyethylene (HDPE) resin designed for tubular film extrusion. It complies with U.S. FDA food‑contact regulations and is suitable for very thin reinforcing film, grocery bags, merchandize bags, disposal waste bags, and shopping bags.
The resin offers excellent processability, draw‑down capability, and high film strength and rigidity. Typical processing conditions include a melt temperature of 180‑240 °C, a blow‑up ratio of 4:1, and a frost line height of 7‑12 times the die diameter. Users should verify suitability for their specific applications, as the manufacturer disclaims responsibility for results from combined product use.
