Introduction to LDPE- Low-Density Polyethelene. Symbol 4 with the acronym LDPE indicates that the plastic is made from LDPE plastic, which stands for low-density polyethylene. This causes the low density to have a less compact molecular structure which is what makes it less dense. Of particular concern is the plastic type which releases gases at the highest rate: low-density polyethylene (or LDPE). Plastic recycling is the reprocessing of plastic waste into new products. It has excellent optical properties and is more resistant to impact than glass. LDPE (low density polyethylene) is a soft, flexible, lightweight plastic material. It is not suited for applications where stiffness, high temperature resistance and structural strength are required. And it resists acids, bases, and oils. Doesnt break easily.
