Plastic bottles are containers made from synthetic materials, primarily polyethylene terephthalate (PET) or high-density polyethylene (HDPE). They are commonly used for packaging beverages, cleaning products, and personal care items due to their lightweight and durable nature. Plastic bottles can be molded into various shapes and sizes, making them versatile for different uses. These bottles are often recyclable, which helps reduce environmental impact when disposed of properly. Many recycling programs accept plastic bottles, allowing them to be processed into new products. However, improper disposal can lead to pollution, as plastic takes hundreds of years to decompose in landfills.
