Those Things About Lipstick Tube Packaging Materials

Lipstick tubes are the most complicated and most difficult of all cosmetic packaging materials. First of all, we must understand why lipstick tubes are difficult to make and why there are so many requirements. Lipstick tubes are a combination of multiple components and functional packaging composed of different materials. In terms of lipstick material, there are also volatile and non-volatile (air-tight/non-air-tight), and most of the filling is automatically filled by the machine (pre-filling, direct filling after filling, etc.), including The loading of the lipstick tube is very complicated, the combination of different parts, poor tolerance control, or unreasonable design, even if the way of lubricating oil is wrong, it will cause downtime or malfunction. These errors are fatal.

The main functional parts of the lipstick tube:

Beaded snail is the core component of the lipstick tube. Beads, forks, spirals, beaded snails and lubricating oil constitute the core of the lipstick tube. It is a bit like a pump core, but it is more complicated than a pump core. Some manufacturers brag about no lubricant beads. Fork screw design, but currently not widely used.

The standardized drawings of bead snails must be standardized. Otherwise, you will not be able to grasp the size. After assembly later, there will be more complicated factors. As a result, it can be predicted that the injection molding material must pass the material compatibility verification, otherwise compatibility problems will occur. Screw it up and screw it down and the problem is over. Beaded snails are the top priority.

The base is generally for the hand feel, and it also adds weight to the iron. The problem of heavy iron glue is equivalent to adding a risk to the lipstick tube. In addition, the vibration in the transportation causes the trouble of degumming inside.

The main quality control indicators of the lipstick tube:

The main control indicators include hand feel indicators, filling machine requirements, transportation vibration requirements, airtightness prevention, material compatibility issues, size interoperability issues, aluminum-plastic tolerance and color issues, productivity issues, and The filling volume must meet the product's declared value problem.

The relationship between the lipstick tube and the material body:

The lipstick material body is soft and hard, too soft, the cup is not deep enough, HOLD does not hold the material body, the lipstick meat will fall out and old when the customer puts on the lipstick, the material body is too hard to apply, the volatile material body (not Decolorizing lipstick), if the air tightness is not good (the lid and the bottom are not well matched), it is very easy to cause the material to dry and the whole product will fail.
