After centuries of development, the cosmetic industry has become very sophisticated and today there are many cosmetic manufacturers producing cosmetic products for men. As a cosmetic manufacturer or cosmetic supplier, we often want to find the most cost-effective packaging tool that will not only meet our packaging needs but also achieve an attractive appearance and high quality at a low price. In this article, we'll talk about how to choose cost-effective plastic bottles for cosmetics.

Spray code of cosmetic plastic bottles
The internal and external surfaces of cosmetic plastic bottles are generally required to be clean and free from pollution, and water stains, oil stains, and foreign substances such as insects and hair are not allowed to appear, nor can they emit odors and irritating smells.
This can be seen and judged directly, and different levels of defects can be defined according to different degrees, and cosmetic suppliers themselves can judge whether they can be within acceptable limits according to the actual situation. The appearance of cosmetic plastic bottles includes the following aspects: whether the color meets the requirements; whether there is an obvious color difference between the colors of the same batch of products; whether there are printing errors or printing ghosts; whether the nesting is accurate; whether there are foreign objects inside the bottle; whether the mouth of the bottle is smooth and burr-free; whether there are stains scratches or unevenness in the bottle; whether there are pockmarks or pits in the plastic bottles of electroplating; whether the hot stamping is off or Displacement, etc.
The main purpose of the functional test is to check whether the cosmetic plastic bottles meet the requirements. In general, the following items are included.
l Length deviation and version deviation: Length deviation refers to the deviation of the outer size from the bottle aperture size. It is generally required that a batch of products should not deviate too much. Plate position refers to the printing position, printing and stamping position, etc., as long as the deviation of the plate position does not exceed too much. Length deviation and plate deviation can be measured by a ruler.
l Cap gap: cap-gap deviation depends on the respective acceptability. Generally speaking, the cap-gap is not less than 0.2cm, not more than 1cm is normal, but some companies require not higher than 0.5cm. this point can also be measured by a ruler.
l Matching degree with accessories: generally, with the outer cover after matching without loosening, the idling phenomenon can be.
l Airtightness: mainly depends on whether there is liquid leakage, generally professional companies use vacuum leak detectors to detect, without conditions, you can load the material body and then inverted it for a few days to see whether there is liquid leakage.
l Capacity: some suppliers provide plastic bottle capacity in fact sometimes does not match what you want, the reason is that the density of the material body is different, or the unit of measurement will also affect the true capacity, sometimes the number of milliliters converted to grams, there may be a few grams of difference, it is necessary to use the material body of their own test.
Product spray code this thing is still quite important, if your product spray code to see unclear, or after a while fell off a bunch, consumers to buy cannot see, it is easy to make people doubt whether this is fake. Before packaging cosmetics, you can sample some of the plastic bottles, using a 3M glue stick in the bottle spray code, see the spraying code off the strong or not. 3M glue stick can still see the spraying code on the batch of cosmetics plastic bottles without too big a problem.
