Using the correct box size is essential. Oversized boxes increase shipping costs and take up valuable storage space. Undersized boxes may not provide enough protection. Take great care when choosing the box size. Also, use protective packaging materials and void fill such as bubble, foam, loose fill, or kraft paper in applications requiring extra protection.
