Introduction to the types and uses of cosmetic tubes

1. The tubes are divided into single-layer, double-layer and five-layer tubes, which are different in terms of pressure resistance, penetration resistance and hand feel. For example, the five-layer tube consists of an outer layer, an inner layer, two adhesive layers, and a barrier layer.

 

Features: It has excellent gas barrier properties, which can effectively prevent the infiltration of oxygen and odorous gases, and prevent the leakage of the fragrance and effective ingredients of the contents.

 

2. Double layer tubes are more commonly used, and single-layer tubes can also be used for medium and low-end ones. The tube calibers are 13#-60#. When a tube of a certain caliber is selected, different capacity characteristics are marked with different lengths. The capacity can be adjusted from 3ml to 360ml. For the sake of aesthetics and coordination, calibers below 35# are commonly used for tubes below 60ml, 35#-45# are usually used for tubes below 100ml and 150ml, and 45# or above is required for tubes above 150ml.

 

3. In terms of technology, it is divided into round tubes, oval tubes, flat tubes, and super flat tubes. Flat tubes and super flat tubes are more complicated than other tubes in terms of process. They are also new tubes released in recent years, so the price is relatively expensive.

 

4. tube caps come in various shapes, generally divided into flat head caps, round head caps, high caps, flip caps, super flat caps, double-layer caps, spherical caps, lipstick caps, and plastic caps. They can also be processed in a variety of processes, such as hot stamping edges, silver edges, colored caps, transparent, spraying, electroplating, etc. Pointed mouth caps and lipstick caps are usually equipped with inner plugs. tube caps are injection molded products, and tubes are drawn tubes. Most tube manufacturers do not produce tube caps themselves.

 

5. Some products need to be sealed after filling. The sealing tail can be roughly divided into: straight grain sealing tail, twill grain sealing tail, umbrella-shaped sealing tail, star point sealing tail, and special-shaped sealing tail. When sealing the tail, you can ask to print the required date code at the sealing tail.

 

6. The tube can be made into colored tubes, transparent tubes, colored or transparent frosted tubes, pearlescent tubes, and can be divided into matte and glossy. Matte looks elegant but is easy to get dirty. The difference between colored tubes and tubes with large-area printing can be judged from the cut at the tail. The cut is white for large-area printing tubes, and the ink used is required to be high, otherwise it is easy to fall off and will crack and reveal white marks after being folded.

 

7. The tube body can be multi-color printed and silk-screened. Hot stamping and silver stamping are calculated by area unit price. Silk-screen printing has better effect and is more expensive. Buyers should choose different factories according to different levels of needs.

 

5 Layer lip gloss tube

Lip gloss tube is an important part of cosmetic packaging. Its five-layer tube material is exquisitely designed and has its own functions, which together ensure the quality and safety of lip gloss. Next, we will analyze the specific functions of these five layers of materials one by one.

 

1. Outer layer

The outer layer is the outermost protective layer of the lip gloss tube, which mainly undertakes the dual functions of protection and beauty. This layer usually uses wear-resistant and scratch-resistant materials to ensure that the tube is not easily damaged during transportation and storage. At the same time, exquisite printing and design also enhance the overall beauty of the product and attract consumers' attention.

 

2. Barrier layer

The barrier layer is located under the outer layer. Its main function is to prevent oxygen, moisture and other external factors from contaminating the lip gloss. This layer usually uses materials with high barrier properties to ensure that the lip gloss remains stable and safe during its validity period.

 

3. Adhesive layer

The adhesive layer is the key part connecting the barrier layer and the functional layer. It not only ensures the close combination between the two layers, but also ensures that there will be no separation between the layers during use. The material selection and process of this layer are very important, which directly affects the durability and service life of the tube.

 

4. Functional layer

The functional layer is the core part of the lip gloss tube, and it can add various functional materials according to different needs. For example, in order to enhance the flexibility and pressure resistance of the tube, specific additives can be added to this layer. In addition, the functional layer can also play a role in regulating the temperature of the lip gloss and preventing the lip gloss from deteriorating.

 

5. Inner layer

The inner layer is the part that is in direct contact with the lip gloss, so its material selection is particularly important. This layer usually uses materials that meet food grade standards to ensure that there will be no pollution to the lip gloss. At the same time, the inner layer must also have good sealing to prevent the lip gloss from leaking.
