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

Plating (UV): Compared to the spray pattern, the effect is bright.

Spray: The color compared to plating is dull.

Frosted sand: a layer of matte texture.

Outer bottle 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 side view shows a small area of ​​the spray.

Spray inside the bottle: It is printed on the inside of the outer bottle and looks larger from the appearance. The vertical plane looks smaller. There is no gap with the inner bottle.

Brushed gold and silver: It is a film. Look carefully to find the gap in the bottle.

Secondary oxidation: It is a secondary oxidation in the original oxide layer, so as to achieve a pattern with a matte surface on the smooth surface or a glossy surface with a dull surface. Mostly used for the production of logo.

Injection color: It is added to the raw material when the product is injection molded. The process is relatively cheap. It is also possible to add bead powder or to add too white powder to make the PET transparent color into an opaque color (add some toner to make the color). The generation of water ripple is related to the amount of added bead powder.
