Primary packaging refers to the first layer of packaging that directly contains a product, providing protection and containment during storage, transportation, and use. It is the most visible and tangible form of packaging, often designed to attract consumers and convey important information about the product. Primary packaging can take various forms, such as bottles, jars, boxes, or bags, and is typically made of materials that are safe for direct contact with the product. Its main purpose is to maintain the quality and integrity of the product, ensuring that it reaches the consumer in optimal condition.
