Primary packaging is the packaging that comes into direct contact with your product. For example, the plastic bag that holds cereal, the aluminum can that contains soda, tubes for toothpaste, or wrappers for nutrition bars. Primary packaging helps not only highlight the overall appearance of the product but also protects it. Focusing on your primary packaging can help enhance the quality and design of your product.
Secondary packaging describes larger packages that are used primarily for branding or display. This can include mailer boxes that hold your cream bottles, folding carton boxes for storing toothpaste tubes or a bag of cereal, or display boxes for storing and displaying set of nutrition bars. Secondary packaging usually contains the label and information about your products, while also acting as the storyboard for your brand. Secondary packaging focuses on utility and helps in transporting your goods or storing them if you are a retailer.
Besides primary and secondary packaging, there is also packaging for shipping (e.g. shipping cartons).
