It is not possible for this company to have only one supplier of packaging materials.

Supply risk: Having only one supplier means that the company is highly dependent on the supplier. If the supplier has problems, such as insufficient production capacity, quality problems, etc., it will affect the company's production and operations.

Compliance issues: In some cases, having only one supplier can cause compliance issues. For example, if a supplier is subject to antitrust charges or has other legal issues, it will affect the company's business.
