What is Package Testing
Package testing or packaging testing involves measuring a characteristic or property involved in packaging. This includes packaging materials, packaging components, primary packages, containers, unit loads, and related processes. The test measures the effects and interactions of packaging levels, package contents, external forces, and end use. It can include controlled experiments, subjective evaluations of people, or field tests. Test documentation is most important: formal test methods, test reports, photos, videos, etc.
Testing is a qualitative or quantitative process. Packaging testing is usually a physical test. Some types of packaging such as food and pharmaceuticals, chemical tests are used to determine the suitability of packaging materials for contact with food. Test programs range from simple tests with small replications to more comprehensive experimental tests. Packaging testing can be extended to a complete life cycle, i.e., aging testing. Testing can measure the life and capacity of the packaging, testing the effectiveness of a package under sealed conditions and the life of the packaging.
Common methods used in packaging product testing
There are sensory testing, physical testing, chemical testing and transport performance testing methods.
1. Sensory inspection methods
Sensory inspection is the use of sensory organs (such as the eyes, ears, nose, mouth, skin, etc.) to check the sensory characteristics of the product method. Among them, visual inspection is widely used in the detection of packaging products. Such as corrugated cartons, cement bags, plastic food bags, egg trays, calcium-plastic caddies, actinium barrels and other products such as the appearance.
2. Physical inspection methods
Physical inspection is the use of physical principles, with the help of a variety of testing instruments and equipment on the physical quantity of the product and its physical properties and mechanical properties of the performance under the action of force, electricity, sound, light, heat, etc. The test method. It includes t metric test method, optical test method, thermal test enamel, electrical performance test enamel mechanical performance test method. For example, the compressive strength of corrugated boxes, breaking strength, puncture strength, peel eagle, side compression strength and other items are determined using physical test methods.
3. Chemical test methods
Chemical test is the use of chemical reagents and instruments to determine the chemical composition of the product and its content by certain methods, and compare the test results with the required quality standards. Thus determine whether the product is qualified. Such as plastic food bags, health indicators, which is determined by chemical testing methods.
4. Environmental testing methods
Environmental testing is to expose the product or material to the natural or artificial environment for testing, so that they may actually encounter storage, transportation and use conditions to evaluate the performance.
What is the importance of packaging testing?
1. For certain types of products, packaging testing is required by regulation: food. Pharmaceuticals, medical devices, dangerous goods, etc. This may cover design qualification, periodic retesting, and control of the packaging process. Processes can be controlled through a variety of quality control management systems, such as HACCP, statistical process control, validation protocols, ISO 9000, etc.
For unregulated products, testing can be performed in accordance with the required contractual or regulatory specifications. The extent of package testing can often be a business decision. Risk management may involve the following factors:
① the cost of the package
②The cost of package testing
(iii) the value of the content being shipped to
④The goodwill of the customer of the value
⑤The risk of product liability
⑥Other potential costs of under-packaging, etc.
An important consideration for packaging is to determine the development of a packaged product that may be damaged in the process of delivery to the end customer. One of the primary purposes of a good package is to ensure the safety of the product during transportation and storage. If a product is damaged in the process, then it will result in the incompleteness of your customer's purchase and possible return of the product by your customer.
4. Packaging testing is usually part of a formal project management plan. Software packaging is usually tested with a new packaging design, revisions to a current design, changes to packaging materials, and a variety of other reasons. Testing a new package design in full-scale production can save time and money.
The purpose of packaging testing
①Package testing may have a variety of uses, such as.
② To determine, or verify, that the requirements of a specification, regulation or contract are met
③To determine if a new product development project is on track: to demonstrate proof of concept
④Provide standard data on other scientific, engineering, and quality assurance functions
⑤ Verify suitability for end use
⑥Provide a basis for technical communication
⑦Provide a technology meant to compare several options
⑧Provides evidence in legal proceedings: product liability, patents, product claims, etc.
⑨Help solve problems with current packaging
⑩Help identify potential cost-saving packaging
