Although some projects require the use of tools, most of cream bottle can be observed visually, and we can also ask the supplier of the packaging material or the cosmetics processing factory to do related tests. If the packaging material fails, the product is ultimately affected. The final experience. As a consumer, if you receive a cream bottle of cosmetics and find that there is a material leakage, it will definitely affect the consumer's trust in this brand.

1. Adhesion: Generally, it depends on whether the printing of the product is durable. It can be tested with 3M tape. If it is stuck, tear it off and then see if there is a word or paint drop, which does not affect normal reading.

2. Drop test, this is a question of whether the simulated product is resistant to drop, and it is also applicable to the e-commerce channel. Everyone has a moment of uneasiness, or a situation where the courier is very violent, and expensive cosmetics fall off and break into one place, which is very worrying, so this is especially important. Generally, it falls a few times around 1 meter, and the components are not loose. , Damaged, if every drop is broken, then the cream bottle must be seriously considered whether to continue to use it.

3. Spraying code: spraying code is still very important. If your product cannot be clearly coded, or it will drop a lot after a while, consumers will not be able to see it clearly when buying it, which is very frustrating. This can be glued down with 3M glue to see if it's not bad. There is no big problem if you can see the code after 3M glue.

4. Transportation bumps: This generally needs to simulate the transportation platform to simulate the situation that occurs during the transportation of the product. If not, you can only try to drop the reference result ~

5. Illumination test, this is the most important for the products on the shelf. Some cream bottles are not of good quality. After a period of light, the color has seriously changed. The product developed by Xiaoliu has appeared. Within three months, the pink has faded into Gray ~ so conditional can be tested and observed for 2-3 months, under the same light source, and watch it at intervals.

6. The solvent resistance of the material body: This test is generally worried about the consumer's use of the material body dug out to get the  cream bottle, the bottle appears to be painted, the picture shows that the cosmetics are used, the material body is less, the bottle I can't see the text clearly ... so, apply a small amount of the corresponding material to the surface of the bottle, and wipe off the material every 12 to 48 hours to observe the paint falling off of the product. You can also use your hands or 3M glue to see it. No paint dropping and word dropping. Or minor cases are actually within the acceptance range.

7. Compatible stability test, generally test for 2-3 months, with a set, settable, room temperature, 50 ℃, 45 ℃, -10 ℃, see if there is a big change between the material and the packaging material, the change description The product is unstable or there is a problem with the packaging material. Specific analysis.

8. Alcohol test: General cosmetics OEM manufacturers produce cosmetics, which are more or less used for disinfection by exposure to alcohol. Generally, they are soaked with 75% alcohol for 30 seconds. They are naturally dried and then tested with 3M glue. The text and patterns are not tested after the test. Affects normal reading is qualified.

9. Fluorescence test: This requires a fluorescent lamp to measure. Generally, the cream bottles that are very white are basically equipped with fluorescent agents, but the migrating fluorescent agents are terrible. The non-migrating fluorescent agents actually have little effect. Just ask the supplier.
