For high density, HDPE is better, it is 0.941-0,965g/cm3. HDPE is used in strong packaging materials like drums, bottle caps, milk bottles. LLDPE is used in coating applications to protect liquid containers content. LDPE is used in light packaging materials like plastic wraps.
LLDPE and HM-HDPE offer distinct benefits for packaging applications: LLDPE provides flexibility and puncture resistance, while HM-HDPE excels in strength, durability, and chemical resistance, making them suitable for various packaging needs.
