Which of the following products is commonly made using blow moulding?

Blow moulding is a manufacturing process primarily used for producing hollow plastic objects. It involves inflating a heated plastic tube, known as a parison, inside a mould to create a desired shape. Large bottles, such as those used for beverages, are a typical product of this technique due to the method's efficiency in forming uniform, lightweight, and strong containers. These bottles often require the properties that blow moulding provides, such as the ability to create intricate shapes and a seamless structure, which are ideal for packaging liquids.

While other options may involve plastic materials, they are not primarily produced through blow moulding. For instance, plastic footballs typically require a different process, such as rotational moulding or stitching of components. Face masks can be made from various materials that often utilize processes like injection moulding or fabric techniques. Agricultural pipes, although hollow, are generally produced using extrusion methods rather than blow moulding, as they often require added strength and specific wall thicknesses that extrusion can provide more effectively.
