Corrugated fiberboard boxes account for over ninety percent (90%) of all shipping containers. There are many different styles of corrugated fiberboard boxes, each with its own strengths. Some provide better cushioning, compression strength, and puncture resistance while others are easier to load and close. The most common style of container is the Regular Slotted Container (RSC).
Corrugated fiberboard boxes may be constructed of single- or double-wall material. Additionally, the corrugated fiberboard used to produce these boxes comes in many grades, the strength of which vary according to the bursting test rating of the combined materials making up the corrugated fiberboard. The most common corrugated fiberboard boxes are 200-pound bursting test single-wall.
- Use boxes that are rigid, in excellent condition with flaps intact. Do not use damaged boxes with torn flaps, holes, crushed sides, or corners.
- Use boxes that meet bursting test standards and not ECT (edge crush) standards.
- Use a minimum 10x10x10 box when packaging and shipping jewelry. Using too small of an outer box can be a signal that something of value may be inside the package.
- Overcompensate for high humidity by using a higher test box.
- Increase the strength of the box by double boxing, lining a box with corrugated sheet or foam planking, or using a high-test container. A wooden crate is another option, if needed.
- Pack flimsy retail gift boxes in a corrugated box. Do not use retail gift boxes for the outer shipping container.
- Do not exceed 85 percent of the weight a box is certified to carry, either inner or outer.
Labeling the Package
- Use only one label on the package.
- Label each package separately. Do not bundle items.
- Remove all previous labels.
- Place the label on the top of the box away from all seams.
- For high-value items, abbreviate the name of the manufacturer on labels or documentation (i.e., Rolex USA + RUSA). Do not use words on the label like “Jeweler,” “Diamond,” or other name that would indicate a high-value item.)
Sealing the Package
- Seal every seam with the 6-strip closure method – top and bottom, the center and the ends. Do not skip a seam.
- Do not use paper tape, cellophane tape, duct tape, masking tape, string, rope and paper overwrap.
- Do not use adhesives for closing containers.
