1. The test report issued by the plastic packaging bag manufacturer.

The testing standards implemented by each manufacturer are different, including national standards, local standards or industry standards, as well as their own corporate standards. Common test items include appearance, strength, residue, etc. The validity and authenticity of the report are the responsibility of the manufacturer.

2. Test report issued by a third-party testing agency.

Generally speaking, plastic packaging bag manufacturers do not send every plastic packaging bag to a third-party testing agency for testing. When will the third-party agency conduct testing? There are generally three situations:

a. The production of plastic packaging bags is submitted for inspection according to its own actual situation.

b. The customer requests to provide the inspection report.

c. Testing required by national laws and regulations.

Regarding the test report issued by the third-party testing agency, the plastic packaging bag manufacturer can provide you with a product test report of a certain batch or a certain material according to the actual situation, but cannot guarantee the specific testing of each plastic packaging bag.
