PE

PE (polyethylene)
Simple and inexpensive to manufacture, PE is the most common type of plastic, accounting for 100 million tonnes or about one third of all plastics produced in 2018 as well as half of all packaging.

Polyethylene is produced from ethylene, which is itself mostly produced from oil or natural gas, although it can be obtained from renewable sources. This plastic is a major waste management issue, not only because of its abundance, but also because it is considered very stable and almost non-biodegradable, meaning it tends to accumulate in the environment.
