LDPE (Low Density Polyethylene) is known for its resistance to extreme temperature changes over time and for its high flexibility. Many products made today use LDPE plastic, including: plastic wrap, plastic containers, plastic lids and tubes, and box liners. Low Density Polyethylene (LDPE) is very flexible, clear and translucent, lightweight, and strong. It is excellent for chemical resistance, water vapor resistance, and sunlight resistance.
