Cosmetic glass bottle processing technology
Spraying color process
1.Aluminum:The appearance of aluminum is wrapped with a layer of film on the inner plastic.
2.Electroplating(UV):compared with spraying,the effect is bright.
3.Spraying:compared with electroplating,the color is dull and matte.
Inner bottle and outer spray:it is sprayed on the outside of the inner bottle.There is a clear gap between the outer bottle and the outer bottle.The spraying area is small when from the size.Spraying inside the outer bottle:It is spraying on the inner side of the outer bottle.It looks larger from the outside and smaller in the vertical plane, and there is no gap with the inner bottle.
4. Brushed gold and silver: It is actually a film.If you observe carefully,you can find the joint gap on the bottle.
5. Secondary oxidation: secondary oxidation is carried out on the original oxide layer,so as to achieve a pattern covered with a matte surface on the smooth surface or a pattern with a smooth surface on the matte surface,which is mostly used for the production of logos.
6. Injection molding color:Toner is added to the raw materials when the product is injection molded.The process is relatively cheap.Bead powder will turn the PET transparent color into an opaque color.
Printing process
1. Silk screen printing:one is high temperature ink silk screen printing.which is characterized by not easy de-colorization,dull color and difficult to produce effect with purple toning:the other is low temperature ink silk screen printing with brighter color and higher requirements for ink,otherwise it is easy to fall off and attention should be paid to the disinfection of the bottle.
2. Hot stamping: It is a thin layer of paper hot stamped on it,So there is no concave and convex feeling of silk screen printing.
Hot stamping is best not directly on PE and PP materials,It needs to be hot stamped first and then hot stamped,or good hot stamping paper can also be not stamped directly.
3. Water transfer printing: It is an irregular printing process in water,the printed lines are inconsistent and the prices is more expensive.
4. Thermal transfer printing:Thermal transfer printing is mostly used for products with large quantities and complex printing.It belongs to attaching a layer of film to the surface and is expensive
5. Offset printing: It is mostly used for aluminum-plastic hoses and all-plastic hoses.If the offset printing is a white color hose,it must use silk screen printing.The offset printing will have the background color showing through and sometimes a layer of bright film will be attached to the surface of the hose or dumb film.
