Which aspects of the selection of cosmetic plastic tube materials?

Electric blanket

 

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 like 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 require 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 point .

 

Regarding double-layer pipes: use high-density polyethylene and low-density polyethylene materials. The high-speed rotation method is employed to realize a consistent mixing effect, and therefore the softness and hardness of the tube are often adjusted appropriately. Compared with the single-layer pipe, the double-layer pipe features a thicker body, better corrosion resistance, lower oxygen permeability, and is employed 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 the way to obtain the specified stiffness? rarity polyethylene, high density polyethylene and linear rarity polyethylene are commonly used for tubes. The stiffness of high-density polyethylene is best than that of low-density polyethylene, therefore the required stiffness are often 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 regulate the short-term or long-term performance of the tube, the subsequent factors should be considered: appearance, pressure/drop performance, environmental stress crack resistance, sealing strength, taste and loss of active ingredients, etc.
