A way to save space and freight is to consider using collapsible or stackable containers for shipping and storage. These types of containers can be folded or nested when empty, allowing for more efficient use of space during transportation. Additionally, utilizing standardized container sizes can help optimize freight costs by maximizing the amount of products that can be transported in each shipment. By implementing these strategies, businesses can not only save money on shipping expenses but also reduce their carbon footprint by minimizing the amount of wasted space during transit.
