Most shippers have clear rules about what is and is not acceptable. Some even have official containers for your use. Many mailing disasters come from weak cartons that break or burst en route. For other cargo, try using plenty of bubble wrap, packing peanuts, cardboard dividers, foam molds or even old newspapers. A carrier may want specific details, like a phone number, zone or pickup time, or make all customers use a standardized label.
Carriers tend to discourage transparent tape, masking tape and duct tape.
Shipping tape is practically a universal standard because it is lightweight, yet strong. Find out if a carrier will accept your package or enforce additional requirements before getting stuck with delays. Most shippers have lots of experience dealing with all sorts of different packages. If in doubt about something, just ask. Depending on the shipper or service, sending that package coast to coast may cost more money.
