How Additives Improve LDPE Properties？
Additives can enhance LDPE properties during injection molding or extrusion or machining by improving characteristics such as strength, flexibility, and resistance to heat, chemicals, and UV radiation.
- Antioxidants improve thermal stability.
- UV stabilizers enhance resistance to degradation from sunlight.
- Fillers and reinforcements can increase strength and stiffness.
- Processing aids improve flow and reduce manufacturing defects.

Which type of PE is recyclable?
High-density polyethylene (HDPE) and low-density polyethylene (LDPE) are both recyclable types of polyethylene. However, HDPE is more widely recycled due to its higher strength and rigidity, LDPE, although recyclable, is less commonly recycled due to its lower density and flexibility.
Is PE resin toxic?
No, PE resin is not inherently toxic. PE is considered a safe material for packaging and food storage purposes. PE resin does not react with food or beverages, and it does not leach harmful substances into the contents it contains.
What are common types of PE?
Common types of PE (polyethylene) include:
- HDPE (High-Density Polyethylene)
- LDPE (Low-Density Polyethylene)
- LLDPE (Linear Low-Density Polyethylene)
- UHMWPE (Ultra-High Molecular Weight Polyethylene)
