Summary of the structure and performance of cosmetic tubes and printing knowledge

In recent years, the traditional metal and glass containers in the daily chemical industry have been gradually replaced by light plastic tube packaging. We can find that the aluminum-plastic composite tube has the following advantages: the aluminum-plastic composite tube is easy to use, and the surface color is bright and beautiful. Therefore, it is widely used in the packaging of facial cleanser, hair conditioner, hair dye, toothpaste and other cream cosmetics in the cosmetics industry, as well as the packaging of creams and ointments in the pharmaceutical industry. Aluminum-plastic composite tube has superior isolation performance, is not easy to break, bright color, beautiful appearance, flexible tube, aluminum-plastic tube advantages, easy to use.

1. The tube can be divided into single-layer, double-layer and five-layer tubes, with different compression resistance, impermeability and hand feeling. For example, a five-layer pipe consists of an outer layer, an inner layer, two bonding layers and a barrier layer. Features: With excellent gas barrier properties, it can effectively prevent the penetration of oxygen and odorous gases, and prevent the leakage of its content, fragrance and effective ingredients.

2. Cosmetic tube can be divided into round tube, oval tube, flat tube and super flat tube. The processing process of flat tube and super flat tube is more complicated than other tubes. This is also a new type of tube produced in recent years, so the price is more expensive.

3. Some products need to be sealed after filling. Tail seals can be divided into straight seals, diagonal seals, umbrella seals, star point seals, and special-shaped seals. The required date code can be printed on the back cover.

4. The tube can be used as colored tube, transparent tube, colored or transparent frosted tube, pearl tube, with matte or bright light. Matte looks elegant, but it gets dirty easily. The difference between the large-area printing of the color tube and the tube body can be judged from the tail cut. White cutting is a large-area printing tube, which requires high ink, otherwise it will easily fall off and crack after folding, and white marks will appear.
