Question

A polymer commonly used as a packaging material is:
A. PVC
B. Bakelite
C. Polythene
D. Polypropylene

Answer 1

In this question we will discuss the polymers which are a major part in our day to day life. We use them very often. We will see how and which polymer is used for packing and is it synthetic or natural.A polymer is a substance or material consisting of extremely enormous atoms, or macromolecules, made out of many repeating subunits. Because of their wide range of properties, both synthetic and natural polymers play essential and ubiquitous in regular day to day existence.

Complete step by step answer:
Polymers range from recognizable synthetic plastics, for example, polystyrene to natural biopolymers, for example, DNA and proteins that are major to organic structure and function. Polymers, both common and synthetic, are made through polymerization of numerous little atoms, known as monomers.
Synthetic polymers are human-made polymers obtained from petroleum oil. From the utility perspective they can be arranged into three principal classifications: thermoplastics, elastomers and synthetic fibers. They are found normally in an assortment of purchaser items, for example, honey, glue, and so forth. A wide assortment of synthetic polymers are accessible with varieties in the main chain as well as side chains. The spines of normal synthetic polymers, for example, polythene, polystyrene and poly acrylates are comprised of carbon-carbon bonds, while hetero chain polymers, for example, polyamides, polyesters, polyurethanes, polysulfide and polycarbonates have different components (for example oxygen, sulfur, nitrogen) embedded along.

Polythene is normally utilized as a bundling material. The most widely recognized polyethylene types utilized in food bundling are high density polyethylene (HDPE), low density polyethylene (LDPE), and direct low density polyethylene (LLDPE).

So the answer is option C.

Note: One must always remember the process of polymerization in order to answer this question. One must have a basic knowledge about polymers, types of polymer – Natural and Synthetic Polymers, which polymer is used as what in our day to day life.
