Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene.
Application
LDPE is used for manufacturing various containers, dispensing and squeeze bottles, tubing, plastic parts of computer components, moulded laboratory equipment and many caps and closures.
Features
Along with boasting impact resistance, LDPE is also stain-resistant, electrically insulating, and waterproof. LDPE is also naturally transparent and reflects light well.
Reusability
Because of its versatility, durability, and recyclability, LDPE is considered a “green” plastic. And while some plastics are simply burned off into energy, others are turned into products we use every day. For example, LDPE can be processed into bottles, bags, trays, and film.
Disadvantages of LDPE
Low melting point: LDPE plastic has a low melting point, which can make it unsuitable for use in products that are exposed to high temperatures. UV degradation: LDPE plastic can degrade over time when exposed to UV radiation, which can limit its use in outdoor applications.
Approval by FDA
These are the food-safe plastic containers that the FDA has deemed appropriate for safe food storage: High-density polyethylene (HDPE plastic) Low-density polyethylene (LDPE plastic) Polyethylene terephthalate (PET/PETE).
