How to choose a high-quality cosmetic plastic tube?

Cosmetic plastic tube, this convenient and economical packaging material has a wide range of applications in the field of daily chemical, and is widely popular.An excellent cosmetic plastic tube can not only protect the contents, but also improve the product level, so as to win more consumers for daily chemical enterprises.So, for daily chemical enterprises, how to choose high-quality osmetic plastic tubes that adapt to their own products?Below we will introduce from several important aspects.

Material stiffness: Daily chemical companies have different requirements for cosmetic plastic tube stiffness, so how to get the desired stiffness? The polyethylene commonly used in cosmetic plastic tubes is mainly low-density polyethylene, high-density polyethylene, and linear low-density polyethylene. The stiffness of high density polyethylene is better than that of low density polyethylene, so the desired stiffness can be achieved by adjusting the ratio of high density polyethylene/low density polyethylene.

Chemical resistance of the material: high density polyethylene has better chemical resistance than low density polyethylene.

Weatherability of the material: To control the short - or long-term performance of the cosmetic plastic tube, you need to consider: appearance, pressure/drop resistance, sealing strength, environmental stress cracking resistance (ESCR value), fragrance and active ingredient loss.

Masterbatch selection: masterbatch plays an important role in cosmetic plastic tube quality control. Therefore, when selecting the masterbatch, the user enterprise should consider whether it has good dispersion, filtration and thermal stability, weather resistance and product resistance. Among them, the product resistance of the masterbatch is particularly important in the use of the cosmetic plastic tube, if the masterbatch is incompatible with the installed product, the color of the masterbatch will migrate to the product, and the consequences are very serious. Therefore, daily chemical enterprises should test the stability of new products and cosmetic plastic tubes (do accelerated tests under specified conditions).

The types of gloss oil and their respective characteristics: the gloss oil used in the cosmetic plastic tube is ultraviolet UV type and hot drying type, which can be divided into bright surface and fog surface from the appearance. Gloss oil can not only provide a beautiful visual effect, but also play a role in protecting the content, and has a certain effect on oxygen, water vapor, fragrance barrier. In general, the hot drying type of gloss has good adhesion to the subsequent bronzing and screen printing, and the ultraviolet UV gloss has better gloss. Daily chemical enterprises can choose the appropriate gloss oil according to the characteristics of their products. In addition, the cured gloss oil should have good adhesion, smooth surface without pitting, folding resistance, wear resistance, corrosion resistance, and no discoloration during storage.

It is believed that from the above aspects, the majority of daily chemical enterprises should be able to pick out high-quality cosmetic plastic tube packaging products.
