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.
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.
Common types of PE (polyethylene) include:
  1. HDPE (High-Density Polyethylene)
  2. LDPE (Low-Density Polyethylene)
  3. LLDPE (Linear Low-Density Polyethylene)
  4. UHMWPE (Ultra-High Molecular Weight Polyethylene)
These types differ primarily in their molecular structure, density, and properties.
