In recent years, the application field of tube packaging has gradually expanded. In the cosmetics industry, makeup, daily use, washing and care products are very fond of using cosmetic tube packaging, because the tube is easy to squeeze, easy to use, light and easy to carry, and can be customized for specifications and printing. The PE tube (all-plastic composite tube) is one of the most representative tubes. Let’s take a look at what is a PE tube.
Components of PE Tube
Main body: tube body, tube shoulder, tube tail
Matching: tube cap, roller ball, massage head, etc.
Main material: LDPE, Adhesive, EVOH
Auxiliary material: LLDPE, MDPE , HDPE
According to the structure of the pipe body: single-layer pipe, double-layer pipe, composite pipe
According to the tube body color: transparent tube , white tube , colored tube
According to the material of the tube body: soft tube, ordinary tube, hard tube
According to the shape of the tube body: round tube, flat tube, triangular tube
Tube Pulling → Tude Docking → Printing (Offset Printing, Silk Screen Printing, Flexo Printing)

Advantage:
a, Environmentally friendly. Compared with aluminum-plastic composite tubes, all-plastic composite tubes use economical and easy-to-recycle all-plastic sheets, which can reduce environmental pollution from packaging waste. Recycled all-plastic composite tubes can be produced after reprocessing can produce relatively low-grade products.
b, Diversified colors. According to the characteristics of cosmetics and different consumer needs, all-plastic composite tubes can be made into different colors, such as colorless and transparent, colored transparent, colored opaque, etc., to bring strong visual enjoyment to consumers. Especially the transparent all-plastic composite tube can clearly see the color state of the contents, giving people a strong visual impact and greatly promoting consumers’ desire to buy.
c, Good resilience. Compared with the aluminum-plastic composite tube, the all-plastic composite tube has better resilience, which ensures that the tube can quickly return to its original shape after squeezing the cosmetics, and always maintain a beautiful, regular appearance. This is very important for cosmetic packaging.
Disadvantages:
The barrier property of the all-plastic composite tube mainly depends on the type and thickness of the barrier layer material. Taking EVOH as the barrier material of the all-plastic composite tube as an example, to achieve the same barrier and stiffness, its cost is lower than that of aluminum-plastic composite tube is about 20% to 30% higher. For a long period of time in the future, this will become the main factor limiting the full replacement of aluminum-plastic composite tubes by all-plastic composite tubes.
