Different Types of Plastic Bottles

  • In present times, plastic bottles are widely used by people as a packaging material for beverages, detergents and other consumer goods. Plastic bottles are safe to use, they are quite economical, and can be used repeatedly. Compounds such as polyethylene terephthalate have been used to produce plastic bottles as they make plastic bottles tough and durable.  There are many reputed plastic bottle suppliers in Cape Town, who offer good quality plastic bottles at reasonable prices.

    Advantages of Using Plastic as a Material for Bottles:

     

    1. Toughness and Durability:

    Unlike glass containers, plastic bottles are more resilient, and they don’t shatter into sharp pieces when dropped. Plastic bottles are quite strong and durable, as the long molecules present in the material, are linked by the shorter ones. Thus, plastic bottles are tough and resistant to various chemicals. Plastic bottles do not usually leak or burst, and they help in keeping the product protected.

     

    2. Wide Range of Shapes and Designs:

    Plastic bottles can be easily moulded into various shapes. Manufacturers incorporate durable handles, measurements marks and pouring lips into several bottles. Moreover, plastic bottles are available in various designs, they range from crystal clear to any shade of colour, and they can be translucent or opaque as well. Plastic bottles do not need any external paint, the colouring material is mixed into the plastic resin so that it never rubs or washes off.

     

    3. Light in weight:

    Plastic bottles are usually light in weight so that they consume less energy. Plastics are soft and they have low melting points. They take less energy to manufacture the glass.

     

    However different types of plastics are used to make plastic bottles.

     

    A. Polyethylene Terephthalate:

    Polyethylene terephthalate or PET is the most popular number of the polyester family. It is most commonly known as the wrinkle –free fibre. This component is broadly used in the textile industry. It has been widely used in the food and packaging industry for its ability to create a liquid and gas barrier. So that oxygen cannot enter to spoil the food. This compound is marked for its light weight, strength, toughness and clarity. PET material can be down cycled in to the polyester fibre that can be used in textiles, padding and insulation (for pillows, comforters, carpets and mouldings). They are also used for tyre reinforcements, conveyors belts, safety belts and coated fabrics and tarpaulins.

     

    B. High Density Polyethylene (HDPE):

    This type of plastic is widely used in making plastic bottles, plastic bags, opaque milk and water containers, bleach, detergent and shampoo bottles, garbage bags, dishes, yoghurt and margarine tubs, cereal box liners and medicine bottles.

     

    C. Polyvinyl chloride ( V or Vinyl or PVC):

    This is second most widely used plastic resin. Soft Polyvinyl chloride or PVC is used in making squeeze bottles, shampoo bottles, mouth-wash bottles, cooking oil, peanut butter jars, detergent and window cleaner bottles, loose-leaf binders, shower curtains, blood bags and medical tubing.

     

    D. Low density polyethylene (LDPE):

    This polyethylene polymer has the basic chemical structure of any plastic polymer. It is widely used for making low-value applications like grocery bags, light-weight bottles and beads. They are tough, durable, and flexible.
