Do you need inner spraying for custom metal cosmetic tube packaging?

When it comes to inner spraying of aluminum cosmetic tube packaging, it is likely that many people will not pay particular attention when purchasing wholesale or custom aluminum cosmetic tube packaging from collapsible aluminium tubes manufacturers, and it is expected that the general public will not even have heard of this empirical term. Then why today to discuss with you "strange" it? Because this processing link in metal cosmetic tube packaging production process, it is easy to be forgotten but a very important production process.

Collapsible Aluminium tubes Manufacturers first to popularize the related knowledge of spraying.

Coating refers to collapsible aluminium tubes manufacturers through spray gun or dish atomizer, by pressure or centrifugal force, dispersed into uniform and fine fog droplets, coated on the surface of the coating method. In the process of spraying, the main problems are highly dispersed paint mist and volatile solvents. So this processing link, not only advanced equipment, production technology should also have experience.

So what are cosmetic Aluminium Tube Suppliers used for interior painting? In the aluminum collapsible tube spraying, the metal squeeze tubes for cosmetics production raw material is epoxy phenolic resin. Because of the high resistance of epoxy phenolic resin, it can effectively isolate acid, alkali, moisture and solvents. In addition, in the production of metal squeeze tubes for cosmetics, whether to carry out metal squeeze tubes for cosmetics and whether to carry out double-layer inner coating will be decided according to the properties of the contents, such as corrosiveness and sensitivity to interact with metal.

In summary, we can clearly know that aluminum collapsible tube in the main role of spraying is:

1, corrosion resistance: epoxy phenolic resin can effectively isolate acid, alkali and other reactions, to achieve corrosion resistance;

2, oxidation resistance: epoxy phenolic resin can effectively isolate water, solvent, etc., to achieve oxidation resistance;

3, anti-shedding: epoxy phenolic resin is not easy to produce action with metal, in order to protect the aluminum tube inner wall metal is not easy to fall off;

Although inner spray has a unique function for metal cosmetic tube packaging, not all Cosmetic Aluminium Tube suppliers need inner spray. If it is filling hair dye, shoe polish, pigment, corrosive substances and other contents, it must be sprayed inside to play a protective role. If the filling is some non-corrosive, not easy to react with metal paste, do not need to carry out internal spraying.

Interior coating in collapsible aluminium tubes manufacturers production of metal squeeze tubes for cosmetics is easy to be ignored but indispensable in the process of collapsible aluminium tubes manufacturers production of metal squeeze tubes for cosmetics. When defining the properties of metal squeeze tubes for cosmetics, it is important to include an appropriate inner spray to protect the tube package and the consumer.
