Plastic products are items made from synthetic materials known as plastics. These materials are created through a process called polymerization, where small molecules called monomers are chemically bonded to form long chains. Common plastic products include containers, bottles, toys, and packaging materials, which are widely used due to their durability, lightweight nature, and resistance to moisture.
Plastics can be categorized into two main types: thermoplastics, which can be melted and reshaped multiple times, and thermosetting plastics, which harden permanently after being shaped. While plastic products offer convenience and versatility, they also raise environmental concerns due to their long decomposition time and potential pollution in ecosystems.
