Basic Knowledge Of Lipstick Tube Packaging Materials-2

Product structure

1.Product Classification:

By components: cover, bottom, middle bundle core (middle bundle, beads, fork and screw), etc. Among them, the middle bundle is generally made of aluminum, which has better hardness and metallic texture after anodizing treatment. There are also those made of plastic through injection molding.

Bead inner diameters: 8.5mm, 8.6mm, 9mm, 9.8mm, 10mm, 11mm, 11.8mm, 12mm and many others; Bead rib count: 4 ribs, 6 ribs, 8 ribs, etc. According to product structure: traditional Lipstick Case box, slender type, lipstick/lip gloss box, lip balm, vermicelli, lip oil, etc. Filling method: Bottom reverse filling, top forward filling

2.The caps for Lipstick Tubes are usually made of aluminum, acrylic, ABS, etc.

3.Base: The base is usually made of acrylic or ABS plastic, and there are also cases where aluminum is used as the base material. Some suppliers, in order to enhance the feel, will add more iron inside. However, if the heavy iron glue has problems, it is equivalent to adding a risk inside the lipstick tube. Coupled with the vibration during transportation, if the glue comes off, it will cause a quality accident, making the customer experience even worse.

4.Middle bundle core

The center core is the core component of the lipstick tube, equivalent to the heart part of the product. Whether the lipstick tube product has a good customer experience or not basically depends on the experience of the center core. It carries the torque, smoothness, force resistance, safety, and bead load-bearing capacity of the entire lipstick tube product.

The bead fork screw is generally of a double helix structure, with a relatively long pitch. After one rotation, the travel distance of the bead is relatively large. Therefore, some users also call it a fast screw. The bead fork screw is the core component of the lipstick tube. It consists of the bead, the fork, the Spiral, the bead fork screw and the lubricating oil, which form the core of the lipstick tube. The bead (cup) is the part of the mouth cup that directly contacts the lipstick material. The fork (fork) is the straight-line movement track of the bead, and the spiral (Spiral) is the spiral movement track of the bead in the upward direction. It cooperates with the fork. To achieve the purpose of the rotation process and the upward movement of the beads.

The bead fork screw is somewhat like a pump core, but it is more complex. Some manufacturers claim that the bead fork screw is designed without lubricating oil, but it is not widely used at present.

The standardized drawings of the bead fork screw must be standardized. Otherwise, if you can't even accurately grasp the dimensions yourself, there will be more complex factors after assembly later. The result can be predicted. The injection molding material must pass the material body compatibility verification; otherwise, if compatibility problems occur, it will be bad when the screw is screwed up and down. The bead fork screw is of Paramount importance.

Cosmetic application

Lipstick tubes, as the name suggests, are used in lipstick and lip balm products.

However, with the rise of lipstick products such as lip sticks, lip gloss and lip glaze, many packaging material factories have made minor adjustments to the packaging structure of lipstick tubes, forming a full range of applications. We will describe them in detail in a classified manner later.
