Many people think that the quality of cosmetic plastic bottles is a matter of quality control or quality inspection. But this is often an immature idea. As a cosmetic developer or operator, quality control of cosmetic plastic bottles is also the key to improving brand reputation, because consumers need not only quality cosmetics, but also packaging products that are aesthetically pleasing and of good enough quality. Therefore, cosmetic manufacturers and stakeholders also need to have a basic understanding of various cosmetic plastic bottles. Today, we will tell you how cosmetic plastic bottles generally need to be inspected.
Here is the list of contents
Light test for cosmetic plastic bottles
Material tolerance test
Compatibility stability test
Alcohol test
Fluorescence test
Light testing of cosmetic plastic bottles is very important for products sold on the shelves because some plastic bottles are not of good quality and become seriously discolored after a period of exposure to light. Therefore, before packaging, you can select some of the purchased products for 2-3 months of light testing, under the same light source, and observe the state of the plastic bottles at intervals.
Material tolerance test
Doing this test is generally worried about the consumer use process, the material body dugout to get the bottle, the bottle appears to the text of the paint situation. Imagine using a cosmetic product with less material and the bottle is not readable, which makes people doubt the product. Therefore, before packaging cosmetics, plastic bottles can be tested for material body resistance. The specific operation method is: to apply a little cosmetic on the surface of the plastic bottle, wipe off the cosmetics at intervals of 12 hours or 48 hours, and observe the phenomenon of paint falling off the surface of the plastic bottle. If there is no paint loss or word loss, or if the situation is slight, it means that the purchased plastic cosmetic bottle has good material resistance.
Compatibility stability test
The compatibility stability test for cosmetic plastic bottles is generally conducted for 2-3 months. The test temperature can be set to room temperature, 50℃, 45℃, -10℃ to see if there is a big change in the cosmetic and plastic bottle if there is a change, it means the cosmetic is not stable or there is a problem with the plastic bottle, which requires specific analysis.
Alcohol test
Generally cosmetic factories produce cosmetics, they will use more or less alcohol for disinfection. The purpose of the alcohol test for cosmetic plastic bottles is to test whether the cosmetic plastic bottles are tolerant to alcohol components. The test is generally done with a concentration of 75% alcohol-soaked plastic bottles for 30 seconds, naturally dried, and then tested with 3M adhesive, the 3M adhesive does not affect the normal reading of the text and pattern on the surface of the plastic bottle is qualified.
Fluorescence test
General very white bottles are basically fluorescent agents, but migratory fluorescent agents are more harmful, non-migratory fluorescent agents actually have little impact, the specific type of fluorescent agents need to ask the plastic bottle supplier. The fluorescence test on cosmetic plastic bottles, although some items need to use professional tools, most of us can be visually observed. Alternatively, you can ask the supplier of the cosmetic plastic bottle or the cosmetic OEM to do the relevant tests and get the authoritative test results. We need to be clear that the cosmetic plastic bottles are not qualified, and ultimately affect the final experience of the product.
