One plastic bag may take anything between 200–1000 years to get decomposed. Other common polyethylene (PE) materials are medium-density polyethylene (MDPE). Why are Plastic Bags bad for the Environment: Plastic is a substance that cannot be recycled or incinerated as burning plastic releases harmful smoke. That stringy web of molecules can be mixed with a wide variety of chemicals, giving plastics diverse properties that allow us to use them for just about anything from shopping bags to clothing, to straws, and furniture. We get asked, which is better, polypropylene or polyethylene. Polyethylene (Polythene) is one of the world’s most popular plastics. Plastic packaging, with its exceptional barrier properties, light weight, low cost, durability, and transparency, is ideal for medical applications.
