Packaging materials refer to the materials used to manufacture packaging containers and other materials that meet the packaging requirements of products. They include metal, plastic, glass, ceramics, paper, composite materials, etc. ‍What needs to be checked in the packaging material inspection and how to do that more effectively?

Packaging Material Quality Inspection Tips

With a serious and responsible attitude towards the production quality of products, the enterprise needs to carry out comprehensive testing on the purchased or self-produced packaging materials. If the enterprise does not have a special testing department, it needs to pass the certification of a professional packaging material testing organization, and can only be put into use after passing the testing. So, what should you know when inspecting and checking packaging materials?
Use the corresponding inspection method
The packaging materials used for different products are different, and some packaging also requires other auxiliary materials. The types of various materials are different. It is obviously not feasible to carry out quality inspections according to a unified method. Therefore, when testing packaging materials, it is necessary to select the corresponding testing method according to the material type of the tested object.

The inspection should be comprehensive
The inspection characteristics of each packaging material are not single. When testing packaging materials, a detailed testing plan should be formulated according to the type of materials to ensure comprehensive testing and avoid missing and wrong testing. For example, when testing carton packaging, in addition to the tests of compression strength, edge pressure strength, puncture strength, and other items, we also need to test the water content.

Make inspection records
When testing packaging materials, the staff needs to make test records along with the test items to ensure that the test behavior is traceable. When there is any objection to the test results, they can be traced according to the test records.

In order to ensure that the inspection of packaging materials used by products has rules to follow and ensure that the quality of packaging materials meets the standards, the third-party testing institutions should not only sample and conduct comprehensive professional testing on packaging materials according to the packaging material testing standards, but also make accurate judgments on the testing results of packaging materials according to national and international standards.
