There are billions of different packages that are filled every day around the world. A package can mean a jar, bottle, box, tube, a can or any other container filled with a product. According to the law, all prepackaged goods should display the volume or net weight and the number of pieces. In the modern world, the value of a product is much more than just its functions and sealable elements including image and safety.
Some simple products incorporate these elements because they can influence their compliance with the regulatory requirements. You should conduct product inspection checks thoroughly, including checking whether packages contain what they are labeled in legal quantities.
