State the levels of packaging

Dear Student, 
There are three level of packaging.

1. Primary Packaging - Primary packaging is the packaging in direct contact with the product itself and is sometimes referred to as a consumer unit. The main purpose of primary packaging is to contain and  protect the finished product  particularly against contamination
2. Secondary Packaging- This type of packaging is used outside of primary packaging to group a certain number of products to create a stock-keeping unit. It facilitates the handling of smaller products by collecting them into a single pack. This type of packaging also provides supplementary protection to help maintain the integrity of the primary packaging. In addition, it can serve as a shipping container for small shipments, making it highly useful in e-commerce.
3. Tertiary Packaging- Often also referred to as bulk or transit packaging, this type of packaging is used to group larger quantities of Stock keeping unit to transport them from point A to point B (e.g. from production facility to point of sale). During this stage, products are handled as distribution units. This type of packaging makes it easier to transport large and  heavy loads safely and securely. In addition to helping prevent damage, it consequently facilitates the handling, storage and transport of goods.
