1, Plastic materials
1, AS: hardness is not high, more brittle (when knocking with a crisp voice), transparent color, and the background bluing can directly contact with cosmetics, food, in ordinary emulsion bottles, vacuum bottles are generally bottle body material, also can make small capacity of the cream bottle. It is transparent.
2. Abs: it belongs to engineering plastics, which is not environmentally friendly and has high hardness. It cannot be directly contacted with cosmetics and food. In acrylic cosmetics, it is generally the material of inner cover and shoulder cover. The color is yellowish or milky white.
3. PP, PE: environmental protection materials, which can directly contact with cosmetics and food, are the main materials for filling organic skin care products. The materials are naturally white and translucent. According to different molecular structure, it can achieve three different degrees of hardness and softness.
4. Pet: it belongs to environmental protection material, which can directly contact with cosmetics and food. It is the main material for filling organic skin care products. Pet is soft and transparent in nature.
5. PCTA, PETG: environmental protection materials, which can directly contact with cosmetics and food, are the main materials for filling organic skin care products, which are soft and transparent. PCTA and PETG are soft and easy to scratch. And it is not commonly used for printing.
6. Acrylic: the material is hard, transparent, and the background color is white. And acrylic in order to maintain a transparent texture often spray outside the bottle, or in the injection of color.
2, Type of packaging bottle
1. Vacuum bottle: cover, shoulder sleeve, vacuum pump, piston. Use with air pressure. The spray head matched has a chicken beak tip (some are all plastic ones or are covered with a layer of electrochemical aluminum), and the duck beak flat head is covered with a layer of plastic.
2, emulsion bottle: cover, shoulder sleeve, emulsion pump, piston. Most of them are equipped with hoses inside. Most of them are made of outer acrylic and inner PP. The cover is made of outer acrylic and inner ABS. If the dairy industry is poor
3, perfume bottle: 1, the internal composition is aluminum external glass (according to the cover part rotation and non rotation two kinds) 2, PP bottle (small injection PP) 3, glass type drip irrigation 4, perfume bottle inside is mostly glass and PP. Large capacity needs to use glass, because the storage time is long, PP is suitable for short-term storage of small capacity. Most of PCTA and PETG don't have perfume.
4. Cream bottle: it has an outer cover, an inner cover, an outer bottle and an inner tank.
A. External acrylic, internal PP material. The cover is made of outer acrylic and inner ABS with a layer of PP gasket.
B. Inner ceramic, PP outer anodized aluminum, cover outer anodized aluminum, PP inner ABS with a layer of PP gasket.
C. The whole PP bottle has a layer of PP gasket inside.
D. External ABS internal PP. There is a layer of PP gasket.
5. Blow molding bottle: mostly made of pet. There are three kinds of lids: Qianqiu lids, flip lids and rotary lids. Blow molding is the direct blow molding of the bottle embryo. It is characterized by a bump at the bottom of the bottle. It's brighter in the light.
6. Blow injection bottle: mostly PP or PE. There are three kinds of lids: Qianqiu lids, flip lids and rotary lids. Blow injection bottle is a process of combining blow injection and blow molding, only one mold is needed. It is characterized by a binding line at the bottom of the bottle.
7. Aluminum plastic hose: the inner part is made of PE and the outer part is packed with aluminum. And offset printing. After cutting, it can be spliced. According to the pipe head, it is divided into round pipe, flat pipe and elliptical pipe. Price: round tube < oval tube < flat tube
8. All plastic hose: all PE material, and first pull out the hose before cutting offset, screen printing, hot stamping. According to the pipe head, it is divided into round pipe, flat pipe and elliptical pipe. Price: round tube < oval tube < flat tube.
Three. Sprinkler head, emulsion pump, hand washing pump and length measurement.
1. Nozzle: Bayonet (half bayonet aluminum, full bayonet aluminum), screw mouth are all plastic, but some are covered with a layer of aluminum cover, a layer of anodized aluminum.
2, emulsion pump: vacuum and straw, are all screw. A layer of anodized aluminum cover can also be set on the large cover and head cap of the screw mouth. It can be divided into two kinds: pointed bill and duck bill.
3. Hand washing pump: the diameter is too large, and it's all screwed. A layer of anodized aluminum cover can also be set on the large cover and head cap of the screw mouth. Generally, steps are threaded, and those without steps are left and right knobs.
Length measurement: length of pipette (from gasket to hose end or fbog length). Exposed length. And the length (equal to the length from the bottle shoulder to the bottle bottom) measured under the large cover.
Specification classification: mainly depending on the product inner diameter (the inner diameter is the diameter of the innermost end of the pump) or large circle height classification.
Nozzle: 15 / 18 / 20 mm all plastic 18 / 20 / 24
Emulsion pump: 18/20/24 MM
Hand washing pump: 24 / 28 / 32 (33) mm
Circle height: 400 / 410 / 415 (only specification code is not actual height)
Note: specifications and classifications are as follows: emulsion pump: 24/415
There are two measuring methods: peeling method and absolute value method. The error is within 0.02g. Pump body size is also used to distinguish measurement.
4, Coloring process
1. Anodized aluminum: the outer surface of aluminum is wrapped on the inner plastic.
2. Electroplating (UV): compared with spray painting, the effect is bright.
3. Spray: compared with electroplating, the color is dull.
Frosting: a layer of frosted texture.
Spraying from inside to outside: it means that there is a clear gap between the spraying from outside and the outer bottle. The area of side view is small.
Spray inside the outer bottle: spray painting on the inner side of the outer bottle with a large area from the appearance. The area of vertical plane is small. And there is no gap with the inner bottle.
4. Wire drawing, gold wrapping and silver wrapping: it's actually a film. Carefully observe the gap between the bottles.
5. Secondary oxidation: secondary oxidation is carried out in the original oxide layer, thus
