The six types of plastic used in packaging include polyethylene terephthalate (PET), polyvinyl chloride (PVC), polypropylene (PP), high density polyethylene (HDPE), low density polyethylene (LDPE) and polystyrene (PS).
PET is an inexpensive type of plastic that is commonly used for food containers, beverage bottles, and other consumer goods. It is also used as a material for making clothing and carpet fibers.
HDPE is a common type of plastic used for manufacturing milk jugs, water bottles, and disposable cups. It is also used to make some toys, such as dolls and stuffed animals.
LDPE is a clear, hard plastic that is often used to package food items. It is made by polymerizing ethylene monomers into polymers. This process creates a material with high strength and durability.
PVC is a type of plastic that has been used since the 1950s. It is commonly found in water pipes, shower curtains, and other household items. PVC is also used to make flexible tubing and medical equipment.
PP is another common plastic that is often used to make food containers, toys, and clothing. It is also used to make some medical devices.
