Several parts of the text indicate that the intended audience is educated adults who are interested in how products are made and how they work. The author goes into detail about purchasing and bagging items in a grocery store, which is a subject that adults have more experience with than kids.
The style of the text is complex and assumes that the reader is educated enough to understand complicated ideas. For example, the information about manufacturing bags is a complicated concept. The words and sentences would be hard to follow if you were not an advanced, skilled reader.
