Secondary packaging is an essential step in the packaging process, designed to group primary packaged products for protection and easy handling. This packaging type enhances shelf appeal and provides additional safety during transportation. Common methods include shrink wrapping, bundling, and carton packing, which help to optimize storage and reduce damage. Secondary packaging is crucial for retail and distribution, ensuring that products arrive at their destination intact while facilitating efficient inventory management. It not only protects products but also plays a vital role in branding and marketing.
