In-mould decoration is a process that is used to make things look cool and special. It puts pictures, designs, or words on a product using a special kind of plastic. First, the picture or design is printed onto a sheet of special plastic that will stick to the product. Then the plastic is put into a special machine called a mould, which heats it up and presses it onto the product in a very precise way. The result is a product that looks very cool and special.
