Question

PET stands for
A) Polyester terephthalate
B) Polyethylene terephthalate
C) Polyether terephthalate
D) Polyethylene terephthalate

Answer 1

Hint:PET is a form of polyester like clothing fabric. It is molded into plastic bottles and containers for food packaging and packaging of beverages, personal care products and many consumer products. It is the most common thermoplastic polymer resin of the polyester family.

Complete answer:
PET consists of a polymerized unit of monomer ethylene terephthalate, with repeating $({C_{10}}{H_8}{O_4})$ units. It is commonly recycled. Depending on its processing and thermal history, polyethylene terephthalate may exist as an amorphous, transparent and as a semi- crystalline polymer. The semi-crystalline material might appear transparent or opaque and white depending upon crystal structure and particle size.

PET in its natural state is colorless, semi- crystalline resin. It can be rigid or semi- rigid based on its processing. PET is a highly valued packaging material because it is strong yet lightweight, non- reactive, economical and shatterproof. PET is safe for food, beverage, personal care, medicine packaging. PET containers are popular for packaging sodas, water, juices, oil, hand soap, medicines etc.

PET is a polymer of ethylene glycol and terephthalic acid. Pallets of PET resin are heated to molten liquid, which then can be molded into almost any shape. It was first synthesized in the U.S. in mid- 1940.
PET is the chemical name of polyester. When PET is used as fiber, it is referred to as polyester, but when used for container and packaging applications, it is called PET.Since PET is a polymer of ethylene terephthalate. Hence the correct option will be B.

Note:There is a way we can find out that the containers are made of PET resin. Pet containers are typically molded on the bottom or side with number 1 surrounded by triangular chasing arrows symbol and PET or PETE written below the triangle. Only PET carries #1 identification code.
