In fact, the cosmetics industry to do the words, I believe that many manufacturers may also have a lot of choice in the packaging material do not understand. General you find hose packaging company, the salesman will first ask you what you are doing, because each of the different products need material may be different, the next is what I want to talk about the five tubes and two The difference between layers of pipe.
First look at this picture:
Five plastic layer with the hose structure diagram
Take a look at this one below:
The so-called five, nothing more than five layers, the outer layer, adhesive layer, the isolation layer, adhesive layer, the inner layer. Five-layer tube is characterized by good gas barrier properties, which can effectively prevent the infiltration of oxygen and odor and the content of special flavor and active ingredient exudation. So the general product is bb cream, sunscreen and Cream will choose five layers of pipe, it is the difference between the two layers is the middle of a bonding film. However, the two-tiered pipe is relatively cheaper than the five-tiered pipe. Some customers choose the two-tiered pipe if they want to be cheaper. After the product is put on the market, it will cause a series of problems and complaints from the customers. More troublesome. Therefore, some products are more aggressive, manufacturers do not care about these cents, and quality is the key.
