Secondary packaging is a term that refers to the packaging of products that have already been packaged in primary packaging, such as individual consumer-sized packages. Secondary packaging is typically used to protect and consolidate these smaller packages into larger groups or units for storage, handling, and distribution.

There are many different types of secondary packaging solutions, including boxes, cartons, pallets, and containers. These solutions are designed to protect the products and ensure that they are handled properly during transportation and storage.

Secondary packaging can be especially important for products that are sensitive to temperature, humidity, or other environmental conditions. By providing an additional layer of protection, secondary packaging can help to ensure that the products remain in good condition and maintain their quality during transport and storage.

In addition to protecting products, secondary packaging can also be used to provide additional information about the products, such as their contents, expiration dates, and handling instructions. This can be especially important for products that are intended for food, pharmaceutical, or other regulated industries.
