Tertiary packaging refers to the outermost layer of packaging used to protect and transport goods during the final stage of distribution. It is typically designed to contain multiple units of primary or secondary packaging, providing an additional layer of protection and organization for the products inside. Tertiary packaging can range from large shipping containers to pallets and shrink wrap, and plays a crucial role in ensuring the safe and efficient delivery of goods to their final destination. This type of packaging not only protects the products from damage, but also serves as a means of identification and branding, making it an essential component of the supply chain process.
