Polyethylene (PE)
Polyethylene is the world’s most used plastic, valued for its balance of durability, flexibility, and affordability. It is available in various forms—LDPE (low-density), HDPE (high-density), and LLDPE (linear low-density)—each tailored to different performance needs. It is non-toxic, chemically inert, and highly resistant to moisture, making it ideal for everything from food packaging to industrial liners and heavy-duty containers.
- Extremely versatile and cost-effective
- Excellent chemical and moisture resistance
- Safe for food contact (FDA approved grades)
- Available in various densities and forms
• Plastic bags, shrink wrap, and film
• Bottles, caps, and containers
• Liners, tanks, and geomembranes
• Toys, piping, and houseware
