Understand the cosmetics packaging materials and technology

Plastic categories: 1, the AS: high hardness, brittle ( When knock is ringing voice) Color, transparent color, and the blue can direct contact with the cosmetic, food, in the ordinary course of lotion bottle, vacuum flask, generally is the material of the bottle, cream bottle of small capacity. Transparent. 2, ABS, belong to the engineering plastic, not environmental protection, high hardness, not directly with the cosmetics, food contact, in acrylic cosmetics packaging materials are generally cover, inside shoulder sleeve material. Yellow or milk white in colour. 3, PP, PE, belongs to the environmental protection material, can be directly and cosmetics, food contact, is the main material of filling organic skin care products, material color white, translucent. According to the different molecular structure, can achieve three different degree of hard and soft. 4, PET: belongs to the environmental protection material, can be directly and cosmetics, food contact, is the main material of filling organic skin care products, PET material is qualitative soft, color is transparent. 5, PCTA, PETG, belongs to the environmental protection material, can be directly and cosmetics, food contact, is the main material of filling organic skin care products, material is qualitative soft, transparent, PCTA and PETG is soft easy to scrape. And not commonly used spray-painting multi-purpose printing. 6, lipstick packaging hose price acrylic: material is hard, is transparent, color and white. X and acrylic transparent texture in order to keep the handiest spray bottle, or in injection for coloring. 1, electrochemical coloring technology aluminum: aluminum appearance, on a layer of inner plastic package. 2, electroplating ( UV) Effect: compared with spray figure out is bright. 3, spraying: compared with the plating color is dark dumb. Frosting: a layer of frosted texture. Spray bottle, inside the outside of the bottle, is, spraying from outside and outside bottle has obvious gap between intervals. The side spray figure area is small. The spray bottle: is to print out the inside of the bottle from the exterior looks larger area. Vertical plane look smaller. And bottle inside with no gap. 4, drawing silvering plated with gold: it is a piece of film, careful observation can find bridging the gap on the bottle. 5, secondary oxidation, was conducted in the original oxide layer secondary oxidation, so as to achieve smooth surface covered with dull surface pattern or dull surface appears smooth decorative pattern. More used in logo. 6, injection color: is the toner is added in the raw materials in the injection molding products. Process is relatively cheap. Can also add a pearl powder, also can add cornstarch make PET transparent color is not transparent color ( Number of toner to add color) 。 The production of water ripple is related to the adding amount of pearl powder. Printing process 1, screen printing, printed after the effect of AoTuGan obviously. Because it is a layer of ink. The rules of the silk screen bottle ( Cylindrical) Can be done once printed. Other irregular piece cost at a time. Color is also a kind of cost at a time. And dry ink and UV ink two points from. Since the dry ink easy off for a long time, can use alcohol to wipe off. UV ink feels AoTuGan obviously difficult to erase. 2, hot stamping, hot stamping is a thin layer of paper on it. There is no screen printing AoTuGan. Don't directly in the PE and PP and hot stamping on these two kinds of material. After need to heat transfer in hot stamping. Or have a good hot stamping paper can also be direct hot stamping. Aluminous model board can do hot stamping, can do hot stamping on at full speed. 3, water transfer printing: printing process is carried out in water without rules. Printed patterns. And the price is more expensive. 4, heat transfer, heat transfer used for high volume, more complex products. Belong to attach a layer of film in the surface. The price is too expensive. More than 5, offset printing, used for aluminium hose and all plastic hose. Offset printing if it is color hose do white must use screen printing, color offset printing will be come out. And sometimes in the hose attached on the surface of a layer of bright film or the film.
