Blow moulding is the process of using a positive pressure to inflate a polymer against a mould, creating a hollow product. In extrusion blow moulding, a ‘parison’ is extruded from a die above a mould and resembles a tube of warm plastic. The parison is clamped by the mould and inflated pneumatically to form the outer geometry of the product. The flash is snapped off and the part is ejected. Typical products made from this process include large container bottles. In stretch blow moulding, a pre-form that has previously been injection moulded takes the place of a parison. Typical products in stretch blow moulding are drinks bottles.

In the local polymer industry, blow moulding is used to form a wide variety of polymer containers.
