1. Use a Corrugated Box   2. Provide Internal Protection    3. Close the Box Securely    4. Use Proper Labeling  


Step 3. Close Your Container Securely

Proper closure of your container is just as important as proper cushioning for the safety and security of your shipment.

To close a box securely, do not use masking tape, cellophane tape, duct tape, string, or paper over-wrap. Instead, use a strong tape -- two inches (five cm) or more in width -- such as these types:
Pressure-sensitive plastic or nylon-reinforced tape
Generally the easiest, most convenient tape to use
Versatile because it adheres without water and sticks to a variety of surfaces and shapes
Apply three strips to both the top and bottom of the box

Water-activated reinforced tape
Use 60 lb (27 kg) grade tape at least three inches (eight cm) wide
Requires only two center-seam strips of tape for both the top and bottom of the box, due to the reinforcing fibers
