Comprehensive Testing Of Cosmetic Packaging Materials

In the entire cosmetics processing and production process, packaging materials are a link that is prone to problems. Based on years of production experience, we have summarized the common problems of cosmetic packaging materials. These issues can lead to delays in product production and scrapped packaging. Therefore, when the packaging materials are sent to the factory, we will test these problems to ensure the smooth completion of production. Let's take a look at the specific content of packaging material testing.

Packaging material appearance inspection:
All the printed copy on the package is consistent with the sample copy, without typos or omissions.

There is no obvious color difference in the single color of the same batch of packaging materials, and the color printing is not rough.

Screen printing, spraying, ink, wiping method test without shedding, discoloration and shedding.

The pump bottle and spray bottle are air-pressed 200 times without damage or failure.
