PET, specifically, serves condiments like mayo and ketchup and single-serve drinks like water. It is a lightweight plastic. However, it is manufactured in a way to make it resistant to spill and wear and tear.
High-Density Polyethylene (HDPE)
The high-density Polyethylene, with the recycling number 2, is a non-transparent plastic, which is hard in structure, so it can easily hold foodstuff without the fear of spills and leaks. It is used in manufacturing plastic milk jugs and squeeze bottles for condiments etc. This type of plastic is highly reliable, which is why it is so significantly used as lunch containers.

LDPE holds the quality of being heat resistant and flexible, which makes it very suitable for six-pack can rings, plastic cup lids, and even plastic shopping bags used to carry fruits and vegetables in grocery stores!
