Question

What characteristic property of plastic makes it useful in making containers for storing food items?
[This question has multiple correct options.]
A. They do not react with food stored in them.
B. They are poor conductors of electricity.
C. They are lightweight and strong.
D. They are non-degradable.

Answer 1

Hint: Plastics are a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects. Plasticity is the general property of all materials which can deform irreversibly without breaking but, in the class of moldable polymers, this occurs to such a degree that their actual name derives from this specific ability.

Complete step by step answer:
Plastics are typically organic polymers of high molecular mass and often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, however, an array of variants are made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters. Plastics have many uses in the medical field as well, with the introduction of polymer implants and other medical devices derived at least partially from plastic. The field of plastic surgery is not named for use of plastic materials, but rather the meaning of the word plasticity, with regard to the reshaping of flesh.
In the packaging of the food containers for the storage of various food items, plastic has a major role because of its light weight and high durability. Plastic does not react with any kind of carbohydrate, fat, protein, vitamin, fiber, etc present in the food and does not get corroded by reacting with any of these species present in the food items.
Thus, the correct option is: A. They do not react with food stored in them.
Also option is C,They are lightweight and strong.
Thus, the correct option is A and C.

Note:
The success and dominance of plastics starting in the early 20th century led to environmental concerns regarding its slow decomposition rate after being discarded as trash due to its composition of large molecules. Toward the end of the century, one approach to this problem was met with wide efforts toward recycling. Today, decomposition of plastic wastes has become a great matter of concern.
