Plain cartons provide less information about what is contained within than cartons with printing or pictures of products. In addition, branded tape often provides additional clues regarding the contents of the package. Therefore, plain tape would likely be preferable for packages containing expensive or personal items. The aim is not to have the package appear suspicious; rather, it should appear similar to one of many other deliveries.

Care should be used when creating return labels
The return label must contain enough information to allow carriers to successfully deliver the package. However, there is no requirement that the label identify the product. A clear return label should lie flat and remain easily readable by scanners. Do not obscure your return labels with comments, stickers, etc. Or large print which may indicate what is contained within. Additionally, using a generic sender name may protect against privacy violations if a company delivers sensitive material, while adhering to all applicable carrier requirements.
Preventing opening
Secured shipping containers may also indicate that a thief attempted to open the container. Securely attach strong tape across both the center seam and both edge seams on both sides of the top and bottom. While securing a container may not prevent theft, torn or removed strips of tape may alert the recipient to potential tampering. Also, use strong tape to close any openings in the container instead of loose strips of tape which may become dislodged during typical transit and handling.
Continuing discretion inside the container
While a discreet exterior box does little to deter a determined thief, the discretion continues when selecting materials used inside the container. Include any inserts such as gift wrapping, notes, paper, or cards intended solely for the recipient’s benefit. Including these types of inserts maintain an atmosphere of discretion while allowing the recipient to still receive a personalized greeting from you.

The box is only one part of a complete delivery solution
Using a discreet shipping box alone accomplishes very little unless combined with informed delivery decisions. Provide tracking notices so the recipient is aware when their package is en route. For high value packages, consider requiring a signature upon delivery, offering secure pick-up locations, or utilize alternative delivery services where possible. Consider providing the driver with the ability to leave the package in a less conspicuous area. By giving recipients multiple options related to their delivery preferences, they are able to determine what level of protection they require for their order.
