Which of the following is a common application of blow molding?

Blow molding is a manufacturing process specifically designed for creating hollow plastic objects by inflating a heated plastic tube (preform) into a mold. One of the most widespread applications of blow molding is in producing plastic bottles. This process is particularly suited for bottle manufacturing because it allows for the efficient production of lightweight, durable, and often perfectly seamless containers, which are essential characteristics for beverage and consumer product packaging.

Plastic bottles are commonly made from materials like polyethylene terephthalate (PET) or high-density polyethylene (HDPE), which can be easily shaped through the blow molding process. The ability to create various designs, sizes, and thicknesses while ensuring consistent wall thickness makes blow molding the preferred method for bottle production. This versatility and efficiency explain why plastic bottles represent a prime application for blow molding technology.
