Which of the following is not a function that a complete package should have?

A complete package serves numerous essential functions, and one of them is to ensure the safety of the product during shipping and storage. This includes protecting the product from damage caused by handling and environmental factors. It also helps in facilitating proper storage and handling, meaning the packaging needs to allow for easy movement and stacking without risking the integrity of the product.

Maximizing marketing appeal is also vital, as packaging plays a crucial role in attracting customers and conveying brand identity. A package that stands out can influence purchasing decisions and is an integral part of the marketing strategy for any product.

While preventing theft is certainly important in certain contexts, such as in retail or warehouses, it is not a primary function of packaging itself. Packaging may include features that deter theft, but its primary roles are related to protection, safety, handling, and marketing. Thus, preventing theft is not inherently a function that is expected from a complete package in the same way that the other options are.
