Delivery boxes have piled up due to the growth of e-commerce and the rise of faster delivery and free shipping services.
Corrugated boxes are the most commonly used shipping medium due to their durability and recyclability.
E-commerce sales, particularly from Amazon, have become a significant market for the containerboard industry.
Amazon is shifting towards using fewer boxes and more recyclable materials, such as plastic mailers for smaller items.
The cardboard box industry faces competition from plastic mailers, but the demand for boxes is expected to continue due to the need for protection for fragile and large items.
