Lipstick tubes are undoubtedly the most expensive and difficult packaging materials in cosmetics. Why are lipstick tubes so expensive? To understand why lipstick tubes are so expensive, we must analyze the reasons from multiple aspects such as the components and functions of lipstick tubes. Firstly, a lipstick tube requires multiple components made of different materials (plastic shell, bead screw, aluminum tube, heavy iron, magnet, etc.), and there are quite a few components alone. Next, the editor will analyze the reasons why lipstick tube cosmetic packaging materials are so expensive from the aspects of lipstick function and quality indicators.

Firstly, the main functional components of lipstick tubes

1. Pearl fork screw
The bead fork screw is the core component of the lipstick tube, consisting of beads, forks, screws, bead fork screws, and lubricating oil. It is somewhat similar to a pump core, but more complex than a pump core. Some manufacturers boast about the oil-free bead fork screw design, but it is not widely used at present.
The bead fork screw is of utmost importance and must be in accordance with standardized drawings and specifications. Injection molding materials must pass material compatibility verification, otherwise compatibility issues may occur and problems may arise when rotated up and down.

2. Magnet
Lipstick tube switches are generally divided into two styles: magnetic suction and snap on. Many customers choose magnetic suction for texture. Today, I will talk about those with magnets. Pay attention to the position of the magnet to ensure that its suction is just right.

3. Heavy iron
The base is usually made of heavy iron for the sake of feel, and if there is a problem with the heavy iron glue, it is equivalent to adding a risk inside the lipstick tube. In addition, the vibration during transportation can cause the inside to peel off, which is a big problem.
