Definitions

  • This disclosure relates generally to packaging, and more particularly to a machine for forming, erecting, and loading a package with a product for shipping such as in an e-commerce environment.
  • Shipping needs for e-commerce and the like include considerable volume of packaging used for shipping products. Multiple items can be grouped in a single order, but in order to economize and ship the products together, they must be packaged together in a single shipping container. In other cases, a single product such as a book may be shipped on its own, but it needs a shipping package or container to protect it during transit. Fulfilment centres where products are placed in shipping containers match orders with one or more products by size to an appropriate shipping container. Given the large variation in order and products sizes, there must be a large variety of shipping containers in stock. Systems that provide custom-sized shipping packages on an order by order basis can considerably reduce the complications in fulfilment centres. The conventional techniques have been considered satisfactory for their intended purpose. However, there is an ever-present need for improved packaging systems and methods. This disclosure provides a solution for this need.
