Labelling is the process of attaching a label to a product, which provides important information about the product. Labels typically contain details such as the name of the product, instructions for use, ingredients, expiry dates, price, and any legal disclaimers or regulatory information. The label plays a significant role in guiding consumers and providing transparency about the product. 
Step 1: Purpose of Labelling. 
  
The primary purpose of labelling is to provide essential information about the product, which can help the consumer make informed decisions. Labels act as a communication tool between the manufacturer and the consumer.
Step 2: Legal Requirement. 
  
In many countries, labelling is a legal requirement for certain types of products, especially food and pharmaceuticals. These labels must meet specific regulations to ensure consumer safety and protect against misleading information.
Step 3: Branding and Marketing. 
  
In addition to providing essential product information, labels are also a marketing tool. Labels often carry brand logos, slogans, and design elements that help make the product visually appealing and identifiable in the marketplace.
Step 4: Consumer Protection. 
  
Labelling helps to protect consumers by providing information about potential allergens, ingredients, or hazards. It also enables consumers to choose products based on their preferences and needs.
