What are the functional requirements for cosmetic tubes?

With the rapid development of the global economy, markets in various countries—especially those with dense populations—have seen a mushrooming growth of cosmetic tube manufacturers. For cosmetics, the quality of the packaging directly affects the product’s market competitiveness, shelf life, and transportation safety. Therefore, cosmetic manufacturers attach great importance to the quality of cosmetic tubes. So, what functional requirements do we have for cosmetic tubes?

Barrier Performance

The primary function of a cosmetic tube is to protect its contents. Many cosmetic ingredients, such as fragrances, are prone to permeation and volatilization. Some ingredients are even corrosive and may damage the layered structure of plastic tubes. In addition, compared with aluminum tubes, plastic tubes have lower density, making it easier for oxygen and water vapor in the air to enter the tube and cause oxidation or deterioration of the cosmetics. Therefore, the barrier performance of cosmetic tubes is crucial, as it directly impacts product quality and shelf life.

Mechanical Protection Performance

After being produced and packaged, cosmetics must withstand transportation, shelf display, and consumer storage. The mechanical protection performance of the tube ensures that it does not burst, leak, or deform during these processes, and that it maintains good pressure resistance and airtightness.

Attractive Appearance

The tube should have a smooth, complete, and uniform surface without scratches, cold cracks, or deformation. The printing should be exquisite to attract consumers, especially the predominantly young female demographic.

Sanhuai Enterprise has been deeply engaged in the tube machinery industry for many years. Our five-layer PE tube extruder is an excellent choice for manufacturing cosmetic tubes. The PE tubes produced by this machine include an EVOH barrier layer, which effectively blocks oxygen and moisture from the air, preventing cosmetic deterioration. This barrier layer also prevents the volatilization of essential oils, fragrances, and other active ingredients, ensuring product effectiveness. In addition, our company produces tube printing machines that use 360° transfer technology to deliver exquisite printing results, making them an ideal choice for cosmetic tube decoration.
