What About Lipstick Tube Packaging Materials

Lipstick tubes are the most complex and difficult of all cosmetic packaging materials. First of all, we must understand why lipstick tubes are difficult to handle and why there are so many requirements. Lipstick tubes are composed of multiple components. Functional packaging composed of different materials also includes volatile and non volatile (airtight/non airtight) lipstick materials, In addition, most of the filling is automatic filling by the machine (filling directly after filling before filling, etc.), including the loading of lipstick tubes, which is very complex. The combination of different parts, poor tolerance control, or unreasonable design, even if the way of lubricating oil coating is wrong, it will lead to shutdown or abnormal functions, which are fatal.

Main functional parts of lipstick tube

The pearl fork screw is the core part of the lipstick tube, that is, the bead, fork, screw, pearl fork screw and lubricating oil form the core of the lipstick tube. It is a bit like a pump core, but more complex than the pump core. Some manufacturers boast that the design of the grease free pearl fork screw is not widely used at present.

The standardized drawing of the prong screw must be standardized, otherwise, the size of the prong screw is not accurate. After the later assembly, there are more complex factors. The results can be expected that the injection molding materials must pass the material compatibility verification, otherwise, the compatibility problems will occur, and the prong screw will end up with problems. The prong screw is the top priority.

The base is generally for hand feeling, and it will also add weight to the iron. If there is a problem with the heavy iron glue, it will add a risk in the lipstick tube. In addition, the vibration during transportation will cause the problem of degumming inside.

Main quality control indicators of lipstick tube

The main control indicators include hand feel indicators, filler requirements, transportation vibration requirements, air tightness, material compatibility problems, size matching problems, aluminum medium plastic tolerance and color problems, production capacity problems, and the problem that the filling volume should meet the product claims.

Relationship between lipstick tube and material

The lipstick material body is soft and hard, too soft, the bead (cup) is not deep enough, and cannot hold the material body. As soon as the customer applies lipstick, the lipstick meat falls out. The material body is too hard to apply, and the volatile material body (does not decolorize lipstick), if the air tightness is not good (the lid and bottom are not well matched), the material body is often dry, and the whole product fails.

Development and design of lipstick tube

Only on the basis of understanding the causes of various requirements can we design various test methods and standardize various indicators. Novice must select mature design of beaded snails and complete the design of universal beaded snails as soon as possible.
