Package testing or packaging testing involves the measurement of a characteristic or property involved with packaging. This includes packaging materials, packaging components, primary packages, shipping containers, and unit loads, as well as the associated processes.
Testing measures the effects and interactions of the levels of packaging, the package contents, external forces, and end-use.
It can involve controlled laboratory experiments, subjective evaluations by people, or field testing. Documentation is important: formal test method, test report, photographs, video, etc.
Testing can be a qualitative or quantitative procedure. Package testing is often a physical test. With some types of packaging such as food and pharmaceuticals, chemical tests are conducted to determine suitability of food contact materials. Testing programs range from simple tests with little replication to more thorough experimental designs.
Package testing can extend for the full life cycle. Packages can be tested for their ability to be recycled and their ability to degrade as surface litter, in a sealed landfill or under composting conditions.
Packaging testing might have a variety of purposes, such as:
Determine if, or verify that, the requirements of a specification, regulation, or contract are met
Decide if a new product development program is on track: Demonstrate proof of concept
Provide standard data for other scientific, engineering, and quality assurance functions
Validate suitability for end-use
Provide a basis for technical communication
Provide a technical means of comparison of several options
Provide evidence in legal proceedings: product liability, patents, product claims, etc.
Help solve problems with current packaging
Help identify potential cost savings in packaging
Packaging tests can be used for:
Subjecting packages (and contents) to stresses and dynamics found in the field
Reproducing the types of damage to packages and contents found in actual shipments
Controlling the uniformity of production of packages or components
For some types of products, package testing is mandated by regulations: food.
