Packaging Material And Process
Sprinklers, lotion pumps, hand wash pumps
1. Nozzle: bayonet (half bayonet aluminum, full bayonet aluminum), the screw is plastic, and can be covered with an aluminum cover, electroplating and other processes.
2. Lotion pump: There are two kinds of common ones: pointed mouth and duck mouth. The bottle press can be divided into vacuum and straw, both of which are screw mouth.
3. Hand washing pump: the caliber is too large, and they are all screw ports. There are various shapes, and different pump heads can be adapted according to the bottle type.
coloring process
1. Anodized aluminum: the aluminum exterior is wrapped in one layer of inner plastic.
2. Electroplating (UV): Compared with the spray pattern, the effect is brighter.
3. Spraying: Compared with electroplating, the color is dull.
Frosting: A frosted texture.
Spraying on the outside of the inner bottle: it is spraying on the outside of the inner bottle. There is an obvious gap between the outer bottle and the outer bottle. Viewed from the side, the spray area is small.
Spray inside the outer bottle: It is spray-painted on the inner side of the outer bottle, which looks larger from the outside. Viewed vertically, the area is relatively small. And there is no gap with the inner bottle.
4. Brushed gold-coated silver: It is actually a film, and you can find the gaps on the bottle if you observe carefully.
5. Secondary oxidation: It is to carry out secondary oxidation on the original oxide layer, so that the smooth surface is covered with dull patterns or the dull surface has smooth patterns. Mostly used for logo making.
6. Injection color: Toner is added to the raw materials when the product is injected. The process is relatively cheap. Bead powder can also be added, and cornstarch can also be added to make the PET transparent color become opaque (add some toner to adjust the color). The generation of water ripples is related to the amount of pearl powder added.
Packaging material printing process
1. Silk screen printing: After printing, the effect has obvious unevenness. Because it is a layer of ink. Silk screen regular bottles (cylindrical) can be printed at one time. Other irregular piece one-time charges. Color is also a one-time fee. And it is divided into two types: self-drying ink and UV ink. The self-drying ink is easy to fall off for a long time, and can be wiped off with alcohol. UV ink has obvious unevenness to the touch and is difficult to wipe off.
2. Hot stamping: a thin layer of paper is hot stamped on it. So there is no unevenness of silk screen printing. And it is best not to hot stamp directly on the two materials of PE and PP. It needs to be heat transfer first and then hot stamping. Or good hot stamping paper can also be hot stamped directly. Hot stamping cannot be done on aluminum and plastic, but hot stamping can be done on full speed.
3. Water transfer printing: it is an irregular printing process carried out in water. The printed lines are inconsistent. And the price 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 on the surface. The price is on the expensive side.
5. Offset printing: mostly used for aluminum-plastic hoses and all-plastic hoses. If the offset printing is a colored hose, silk screen printing must be used when making white, as the offset printing will show the background color. And sometimes a layer of bright film or sub-film is attached to the surface of the hose.
