Katie Bagli introduced the students of Std. The advantages can be dramatic, such as the ability to use a hand, close an open wound, or remove skin cancer, or subtle, such as the confidence a young woman might get after a rhinoplasty.
Some plastics are partially crystalline and partially amorphous in molecular structure, giving them both a melting point the temperature at which the attractive intermolecular forces are overcome and one or more glass transitions temperatures above which the extent of localized molecular flexibility is substantially increased.
This fine tuning of the properties of the polymer by repeating unit's molecular structure has allowed plastics to become such an indispensable part of twenty first-century world. Examples of such classes are the thermoplastic and thermoset, elastomer, structural, biodegradable, and electrically conductive.
The production and consumption of plastic is millions times more than their decomposition. Disadvantages of Plastics Disadvantages of Plastics are 1. This has had terrible consequences on many marine species, which can lead to consequences for those that eat fish and marine life for nutrients — including people.

In other words, long after you are no more, the plastic bag used by you will be in existence. The use of plastics is constrained chiefly by their organic chemistry, which seriously limits their hardness, density, and their ability to resist heat, organic solvents, oxidation, and ionizing radiation.
Plastic materials have lots of advantage with many disadvantages.
And trash bags are only used once, unlike plastic bags that can be used at least twice. Time also varies with the size of the bottle. This makes the bags stay in environments longer, in turn leading to great build-up on the natural landscape much more than degradable materials like paper.
In other words, the more plastic bags you use, the greater the chances of environmental damage.
To customize the properties of a plastic, different molecular groups "hang" from the backbone usually they are "hung" as part of the monomers before linking monomers together to form the polymer chain.
Plastic bags are made of petrochemicals, a nonrenewable resource. Advantages and Disadvantages of Plastic Full Essay in Points Disadvantages of Plastic Decomposes Slowly As like advantages the first Disadvantages of Plastic is the strong and durability is beneficial when it comes to protection but these same features turn evil when it comes to decomposition.
