The most expensive and difficult cosmetic packaging material is PP Lip Balm Tube. Why are lipstick tubes so expensive?
If we want to know why lipstick tubes are so expensive, we must analyze the reasons from the components and functions of lipstick tubes. Because a lipstick tube requires multiple components of different materials (plastic shell, bead fork screw, aluminum tube, heavy iron, magnet, etc.)
1. Bead fork screw
The bead screw is the core component of the lipstick tube. The beads, forks, spirals, bead screws and lubricating oil form the core of the lipstick tube. It is a bit like a pump core, but more complicated than the pump core.
Some manufacturers also brag about the lubricant-free bead and screw design, but it is not widely used at present.
Bead fork screws are a top priority and must be in accordance with standardized drawing specifications.
The injection molding material must pass the material body compatibility verification, otherwise compatibility problems will occur and problems will easily occur when screwing in and out.
2. Magnet
Lipstick tube switches are generally divided into two styles: magnetic suction and snap-on. Many customers choose magnetic suction in order to pursue quality. They should also pay attention to the position and quality of the magnet to ensure that the magnet’s suction force is just right.
3. Heavy iron
The base is usually made of heavy iron for the sake of feel. If there is a problem with the heavy iron glue, it is equivalent to adding a risk to the inside of the lipstick tube. In addition, the vibration during transportation will cause degumming inside, which will cause great trouble.
In terms of the lipstick material, it can be divided into volatile and non-volatile types (airtight/not airtight). If the airtightness is not good (the lid and bottom do not match well), it is very easy to cause the material to dry out and the entire product will fail.
In addition, when filling, most of them are automatically filled by machines (front filling, back filling, direct filling, etc.). We must pay attention to every detail such as the tolerance of the lipstick tube and the combination structure of the parts. Mistakes are irreversible.
Finally，Main quality control indicators of Empty Lipstick Tube Custom
The main control indicators include hand feel indicators, filling machine requirements, transportation vibration requirements, air tightness, material compatibility requirements, and size matching issues. There are also issues such as color, production capacity, and filling volume that must meet the product’s marked capacity.
