How to take the better airless tube

Diversification of plastic cosmetic tube packaging
plastic cosmetic tubes can be classified into single-layer tubes and multi-layer tubes according to material classification.
     Single-layer tubes include metal tubes and plastic extrusion tubes; multilayer tubes include aluminum-plastic composite tubes, plastic composite tubes, and

plastic coextruded tubes. According to the classification of processing technology, tubes can be divided into seamless tubes and seamed tubes. Seamless tubes include

cold stamping, roll forming, and extrusion molding; seamed tubes include high frequency welding, ultrasonic welding, heat welding, and other forming methods. Among

them, extrusion molding can process multi-layer or single-layer plastic cosmetic tubes.
Full explanation of PU tube
I would like to ask you a question: Have you ever heard of PU tubes? Maybe some workers will know what this is and what it is used for. More people may not understand

what this thing does in our lives and bring life changes to our lives. In fact, PU tubes exist in our lives and are an essential item. If you don’t believe it, now I

’ll introduce you to what is a PU tube.
  Introduction: PU tube is a pipe as its name suggests. It is used to transport things. Some company staff use PU tubes to transport air, materials and liquids.
  Note: Even if the PU tube has a lot of advantages, but the staff should pay attention to safety when using the tube, but also always pay attention to unexpected

situations. The following are notes that we must keep in mind: The characteristics of a tube are soft, but we cannot stretch the tube excessively, otherwise it may

cause the internal structure of the tube to break. The second is to avoid storage or to work under high temperature conditions. The tube is easily heated and cracked.

The drawback of the third tube is that it is easy to 'grow', so it must be kept in a dry place. In this way, the PU tube can be better protected so that it can be used

to its fullest extent and play a greater role.
  Advantages and disadvantages: PU tubes can be used to transport gases, liquids and objects. Because it is a tube, it is lighter in terms of transport and carry. In

addition to its advantages of light weight, it is also resistant to corrosion. It is not easily eroded by chemicals and destroys the internal structure of the tube. It

is not afraid of friction and can be used for a long time. However, due to the characteristics of the tube itself, it is very easy to use the 'young man'. It becomes

'elderly person'.
  No matter what kind of product, performance is the primary concern of people, and it is the most noteworthy. In fact, no matter what time the product's attributes

are inseparable from the quality of support, only good quality can win the customer's approval, and only good service can make more people use it more at ease, and

therefore also Need everyone to pay attention to the latest situation in a timely manner. You can solve any problem in time and solve it.an solve any problem in time

and solve it.
