The Features of Plastic Cube for Cosmetics

Nowadays, the plastic tubes commonly used in cosmetic packaging include Aluminum plastic barrier laminated tubes (ABL tubes), and plastic barrier laminated tubes （PBL tubes）. They are designed to meet a wide range of needs for cosmetic packagings, such as the requirement of health and barrier properties.

1. ABL Tube

ABL tube is a kind of packaging container made of aluminum foil and plastic film through a co-extrusion compounding process and then processed into a tube by a special tube-making machine. ABL tube is mainly used in cosmetics packaging with high requirements for hygiene and barrier properties, and its barrier layer is generally made of aluminum foil, and the degree of barrier depends on the pinhole size of aluminum foil.

ABL tube has the following advantages in the process of use. The first advantage is high barrier properties. Aluminum foil has the characteristics of light-blocking, oxygen blocking, and water blocking. On the one hand, it can prevent external substances from entering the interior of cosmetics to prevent oxidation and deterioration of cosmetics. On the other hand, it can prevent water or fragrance components in cosmetics from spreading to the outer environment through the tube, thus providing the quality guarantee of cosmetics. The second advantage of the ABL tube is that it is at a low cost. To achieve the same barrier properties performance, the ABL tube used less material than the PBL tube. It is more economical. 

2. PBL Tube

PBL Tube is all plastic components, divided into 2 layers PE tube and 5 layers PE tube. 2 layers tube is generally used for low-grade fast-consuming cosmetic packaging. 5 layers PE tube is usually used for low-grade cosmetic packaging due to the existence of side seams on the surface of the tube.

The first advantage of the PBL tube is that the PBL tube is recyclable. Compared with the ABL tube, the PBL tube is made of an all-plastic sheet that is economic and easy to recycle. It can reduce the pollution from packaging waste. Recycled PBL tubes after reprocessing can produce relatively low-grade products. The second advantage is that the PBL tube has more color options. According to the characteristics of cosmetics and various consumer needs, PBL tubes can be made in different colors, such as transparent, colored transparent, color opaque, etc., giving consumers a strong visual enjoyment. Especially in the transparent PBL tube, the color and state of the contents can be clearly seen. The transparent tube will greatly stimulate consumers' desire. It also has good resilience. Compared with the ABL tube, the PBL tube can quickly return to its original shape. It always maintains a beautiful, regular appearance. This is important for cosmetic packaging.

3. Drawbacks of 2 kinds of tube

The two types of plastic tubes for cosmetic packaging mentioned above have their own drawbacks. Due to the use of aluminum foil, the ABL tube has many disadvantages. Such as invisible contents, bad environmental protection, poor resilience, etc.

The degree of PBL tube barrier mainly depends on the type of barrier layer material, thickness, etc., to EVOH for the barrier layer material of the full plastic composite hose. For example, To achieve the same barrier properties performance, the ABL tube used less material than the PBL tube. In the future, this will become the main factor limiting the PBL tube to replace the ABL tube.
