Plastic Material Category

1. AS: Hardness is not high, relatively crisp (there is a crisp sound when knocking), transparent color, and background blue can directly contact cosmetics, food, in ordinary emulsion bottles, vacuum bottles are generally bottle body materials, can also make small capacity cream bottles. It is transparent.

2. ABS: It belongs to engineering plastics. It is not environmentally friendly and has high hardness. It can not be directly contacted with cosmetics and food. In acrylic cosmetics package, it is generally the material of inner cover and shoulder cover. The color is yellowish or milky white.

3. PP, PE: It belongs to environmental protection material. It can contact cosmetics and food directly. It is the main material for filling organic skin care products. The material is white in color and translucent. According to different molecular structures, three different degrees of hardness and softness can be achieved.

4. PET: It belongs to environmental protection material. It can directly contact with cosmetics and food. It is the main material for filling organic skin care products. The material of PET is soft and its color is transparent.

5. PCTA and PETG are environmentally friendly materials. They can be directly contacted with cosmetics and food. They are the main materials for filling organic skin care products. The materials are soft and transparent. PCTA and PETG are soft and easy to scratch. And printing is not often used.

6. Oral infrared shell price acrylic: harder material, transparent, and white background. In order to maintain a transparent texture, acrylic often sprays in the outer bottle or colors during injection molding.

Coloring process

1. Aluminum electrolyte: Aluminum exterior is wrapped on the inner plastic layer.

2. Electroplating (UV): Compared with spray painting, the effect is bright.

3. Spraying: Compared with electroplating, the color is dark and dumb.

Frosting: a layer of frosted texture.

Internal and external spraying: spraying on the outside of the inner bottle. From the appearance, there is a clear gap between the outer bottle and the inner bottle. On the side, the area of the spray chart is small.

Inner spraying of outer bottle: The inner side of outer bottle is sprayed and painted, which looks larger from the outside. Vertical plane has smaller area. And there is no gap with the inner bottle.

4. Gold and silver wrapped in wire drawing: It's really a film. Careful observation can find the joint gap on the bottle.

5. Secondary oxidation: the original oxide layer is oxidized twice, so as to achieve the smooth surface covered with dark dumb surface pattern or dark dumb surface appears smooth surface pattern. It is mostly used in the production of logo.

6. Injection colour: It is to add colour powder to the raw material when the product is injected. The process is relatively inexpensive. Pearl powder can also be added, or too white powder can be added to make PET transparent color into opaque color (add some color powder can be toned). The formation of water ripple is related to the amount of pearl powder added.

Printing process

1. Silk Printing: The effect after printing has a distinct concave and convex feeling. Because it's a layer of ink. The regular bottle (cylindrical) of silk printing can be printed at one time. Other irregular one-time costs. Color is also a one-time cost. And there are two kinds of self-drying ink and UV ink. Self-drying ink is easy to remove for a long time, and can be wiped off with alcohol. UV ink feels distinctly bumpy and difficult to erase.

2. Stamping: A thin layer of paper is stamped on it. So there is no impression of convexity in silk printing. And hot stamping should not be directly on PE and P P. It is necessary to heat transfer first and then hot stamp later. Or a good hot stamping paper can also be directly stamped. Aluminum plastic can not be hot stamped, full speed can be hot stamped.

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 quantity and complicated printing. It belongs to attaching a layer of film to the surface. The price is on the high side.

5. Offset printing: mostly used for aluminium plastic hose and full plastic hose. If offset printing is made of color hose white, it must be silk-printed, and the offset printing will have a background color. And sometimes a layer of bright film or sub-film is attached to the surface of the hose.
