Step 1: PET preform
It is made through an **injection molding process**, where molten PET resin is injected into a mold to form the preform. Later, in a **blow molding process**, the preform is reheated and stretched into its final shape — such as bottles for water, soft drinks, edible oil, cosmetics, and household products.
