Cosmetic packaging materials should highlight the novelty and bright spots of products and improve their market competitiveness. Because when consumers choose products, they are often attracted by the beauty and color of the product packaging. So what processes do you need to make cosmetic packaging materials? The manufacturing process of cosmetic packaging materials is mainly divided into two processes: coloring and printing.

1. 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.


The brushed gold and silver film is actually a piece of film, and you can find the gaps in the bottle through careful observation.


Secondary oxidation: secondary oxidation is performed on the original oxide layer, so as to achieve the pattern of dull surface covering the glossy surface or the pattern of glossy surface appearing on the dull 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. Pearl powder can also be added. Adding cornstarch will make the transparent color of PET become opaque.


2. 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. The color is also a one-time cost, which is divided into two types: self-drying ink and UV ink.

 

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


Hot stamping is best not to directly on the two materials of PE and PP, you need to perform thermal transfer before hot stamping, or you can also directly hot stamp with good hot stamping paper.


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 products with large volume and complicated printing. It is a kind of film attached to the surface and the price is relatively expensive.


Offset printing: It is mostly used for aluminum-plastic hoses and all-plastic hoses. If the offset printing is a colored hose, 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 hose. membrane.
