Before you cutting the strapping, also consider what may be inside the box before you open it. For example, some manufacturers of auto and mattress springs compress the springs in the shipping container and then band it to save space. Bales of cotton, burlap, and similar materials are also highly compressed before banding. Obviously, when these bands are cut, these could be a violent recoil action. Skill and special training are required before opening containers of this nature.
