Cosmetic packaging material production process

So what process do you need to make cosmetic packaging materials? The manufacturing process of cosmetic packaging materials is mainly divided into two processes: coloring and printing.

01 Coloring process

Anodized aluminum: aluminum exterior, wrapped with a layer of plastic on the inner layer.

Electroplating (UV): Compared with the spray pattern, the effect is brighter.

Spraying: Compared with electroplating, the color is dull.

Outer spraying of the inner bottle: spraying on the outside of the inner bottle, there is a clear gap between the outer bottle and the outer bottle, and the spraying area is small when viewed from the side.

Inner spraying of outer bottle: It is sprayed on the inner side of outer bottle. It looks larger in appearance, and smaller in vertical plane, and there is no gap between inner bottle and inner bottle.

Brushed gold and silver: It is actually a film, and you can find the gaps on the bottle body by carefully observing it.

Secondary oxidation: Secondary oxidation is performed on the original oxide layer to achieve a pattern that is covered with a dull surface on the glossy surface or a pattern on the dull surface with a glossy surface, which is mostly used for logo production.

Injection color: Toner is added to the raw material when the product is injected. The process is relatively cheap, and pearl powder can also be added. Adding cornstarch will make the transparent color of PET become opaque.

02 Printing process

Silk screen: The effect after printing has obvious concavity and convexity, because it is a layer of ink.

The regular bottle (cylindrical type) of silk screen printing can be finished at one time, and the other irregular one has a one-time cost, and the color is also a one-time cost, which is divided into two types: self-drying ink and UV ink.

Hot stamping: It is a thin layer of paper stamped on it, so there is no bumpy feeling of silk screen printing.

Hot stamping is best not directly on the two materials of PE and PP. It needs to be thermally transferred first and then hot stamped, or if there is a good hot stamping paper, it can also be directly hot stamped.

Water transfer: It is an irregular printing process carried out in water. The printed lines are inconsistent and the price is more expensive.

Thermal transfer: Thermal transfer is mostly used for large-volume, complex-printed products. It is a layer of film attached to the surface, and the price is relatively expensive.

Offset printing: It is mostly used for aluminum-plastic tubes and all-plastic tubes. If the offset printing is a colored tube, you must use silk screen printing. The offset printing will show the background color, and sometimes a bright film or sub-layer is attached to the surface of the tube. membrane.
