Which aspects of the choice of cosmetic plastic tube materials?

cosmetic plastic tube

Choice of cosmetic plastic tube:

1. Hygiene of cosmetic plastic tube materials

First of all, the materials used should meet the relevant national health standards, and harmful substances such as heavy metals and fluorescent agents should be controlled within the scope of the prescribed standards.

2. Barrier properties of cosmetic plastic tube materials

If the products of some daily chemical companies that need to be packaged are certain products that are particularly sensitive to oxygen or products with very volatile aroma, then a five-layer co-extruded tube should be selected at this time.

Regarding double-layer pipes: use high-density polyethylene and low-density polyethylene materials. The high-speed rotation method is used to achieve a uniform mixing effect, and the softness and hardness of the tube can be adjusted appropriately. Compared with the single-layer pipe, the double-layer pipe has a thicker body, better corrosion resistance, lower oxygen permeability, and is used by most daily chemical companies and cosmetic manufacturers.

3. The stiffness of cosmetic plastic tube material

Daily chemical companies have different requirements on the stiffness of tubes, so how to obtain the required stiffness? Low density polyethylene, high density polyethylene and linear low density polyethylene are commonly used for tubes. The stiffness of high-density polyethylene is better than that of low-density polyethylene, so the required stiffness can be obtained by adjusting the ratio of high-density polyethylene and low-density polyethylene.

4. Chemical resistance of cosmetic plastic tube materials

High-density polyethylene has better chemical resistance than low-density polyethylene.

5. Weather resistance of cosmetic plastic tube materials

In order to control the short-term or long-term performance of the tube, the following factors should be considered: appearance, pressure/drop performance, environmental stress crack resistance, sealing strength, taste and loss of active ingredients, etc.

About Jiangsu Xinfly Packaging Co., Ltd. is an enterprise specializing in the research and production of cosmetic tubes, which are mainly used for cosmetic packaging, food packaging, pharmaceutical packaging, hotel supplies packaging, personal care product packaging, etc. Since its establishment, after many years of ups and downs, it now has professional manufacturing experience and first-class automation equipment, with three tube production lines and an annual output of tens of millions.
