The making process of the plastic bottles and matters needing attention
Cleanser tube wholesale is a process of two-way stretch blow molding process, in this process, PET chains are arranged two-way stretch, orientation, and, thus increasing the bottle wall mechanical performance, can improve the tensile, tensile, impact strength, and has good air tightness. While stretching helps to improve the strength, but not excessively stretching, to control good stretch blow ratio: radial not more than 3. Five to four. 2, the axial not more than 2. 8 ~ 3. 1. The bottle preform thickness not more than 4. 5mm。 In the plastic bottle blowing and is between temperature and crystallization temperature, general control between 90 ~ 120 degrees. PET show is within the range of the high elastic state, blow molding, cooling rapidly become transparent bottle after setting. In step method, the temperature is determined by the cooling time length in molding process ( Such as aoki bottle blowing machine) , so to join good note - The relationship between the two stations. Blow molding process are: tensile - A blow - Second blow, three action time is very short, but be sure to cooperate well, especially the former two step determines the overall distribution of the material, by the quality of bottle blowing. So to adjust good: stretch the starting time, stretching rate, blow the start and end time, air pressure, blowing air flow, etc, be like likely, can control the temperature of the bottle preform general distribution, bottle preform, both inside and outside wall temperature gradient. Hand cream hose wholesale not proper heating drinks 'buy heating, because their intestines and stomach bad, can warm the stomach, can also warm hands. Just heating chose a bottle of milk tea ', says ms Yang vendors want to very thoughtful, so cold day, walk on the outside, or would like to buy some warm. , experts said, common on the market of mineral water, milk tea, carbonate and other plastic triangle within the number '1', representing the PET, labeled '1' plastic resistant to high temperature at 65 degrees Celsius, it is safe, is used in low temperature is not suitable for repeated heating, heating or even boil, PET would release a heated DEHP toxic substances, endanger human body health.
What are the customers' concerns about cosmetic packaging enterprises
In the choice of cosmetics package enterprises, first of all to see whether the qualification of the enterprise is in line with the requirements of the national cosmetic package production. If the enterprise's qualification is blurred, it shows that the enterprise does not meet the national production requirements and the quality of the product can not be guaranteed. So when choosing cosmetic packaging enterprises, we must check the production qualification of enterprises.
How do small and medium-sized enterprises develop product of cosmetics.
1. Don’t make too many products. There are more and more small and medium-sized cosmetic manufacturers. Their products almost cover all kinds of cosmetics. You can see that there are many products, but in fact, they have many disadvantages. The first one is that the sales volume is not necessarily high. The 80/20 law states that 80% of the benefits of any entity come from 20% of the products, that is, 80% of the products can only contribute 20% of the benefits, which is not economic. The second one is that too many product lines are relatively backward in management, and their own strength is insufficient, enterprises can’t grasp the dynamics of consumers' hearts, so there are a lot of products which are not need by consumers. Third, most companies focus on speculation and bargain hunting. Too many product lines limit the development of an enterprise. It is difficult for consumers to form an understanding of the enterprise without a major product. And it is impossible to find the market position without the c

Types and characteristics of cosmetic tube
Tubes are divided into single-layer, double-layer and five-layer tubes, which are different in anti-pressure, anti-penetration and hand feeling. For example, five-layer tube is divided into outer layer, inner layer and two bonding layer, and another barrier layer.
