There are a number of symbols which commonly appear on packaging products. Some of these indicate whether the item is recyclable, while others show the recycled material content.
There are a wide range of plastics used in packaging. To make sorting and thus recycling easier, the American Society of Plastics Industry developed a standard marking code to help consumers identify and sort the main types of plastic. These logos are molded in the plastic and describe the type of plastic used for sorting purposes only. The logos do not indicate that the products are recycled or recyclable. These types and their most common uses are shown below:
