LDPE sheets are a thermoplastic created from the ethylene monomer. Due to their flexibility, toughness, and relative transparency, they find their main use in film applications. High levels of short-chain branching in LDPE have an impact on the material's structure, physical attributes, and processing traits. Since LDPE is less crystalline than HDPE, these are more flexible and opaque. A lower melting temperature is another effect of the less crystalline structure. Because of these characteristics, LDPE sheets can be utilised in places where HDPE cannot, such as packaging film and moulded products. These are created using metallocene catalysts or Ziegler-Natta catalysts at low temperatures and pressures. Owing to their adaptability, strength, and light weight, the said items are popular for making roofs.
