The advantages of glass bottles
In cosmetic packaging materials, glass bottles are increasingly recognized by the market because of their significant characteristics. This is mainly because the use of glass bottles has the following advantages:
1, the glass material is lead-free and harmless, the barrier performance is good, can well prevent the oxidation of various gases on the object in the bottle, and can effectively prevent the volatile components of the object in the bottle from volatilizing.
2, glass bottles can be recycled and used repeatedly, reducing the cost of enterprise packaging, but also conducive to environmental protection.
3, the glass texture is transparent, the internal material is clearly visible, and the “appearance level + effect” delivers a high-level feeling to consumers.
4, glass bottles are safe and sanitary, non-toxic and harmless, with good corrosion resistance and acid resistance, and have special packaging advantages for the cosmetics industry.
2, the use of glass bottles in cosmetics (cream bottles, serum, toner, oil bottles)
Glass bottles used in cosmetics are mainly divided into: skin care products (cream, lotion), foundation, perfume, essential oils, nail polish several categories, the capacity of more than 200ml is rarely used in cosmetics.
Glass bottles are divided into wide mouth bottles, narrow mouth bottles.
The solid paste is generally used in a wide-mouth bottle, which should be equipped with an electrochemical aluminum cap or a plastic cap. The bottle cap can be used for color spray and other effects, such as cream bottles, mask bottles and other commonly used wide-mouth bottles;
The emulsion or water paste is generally used in a narrow-mouth bottle, and it is appropriate to use a pump head, such as a cap, it is necessary to add a plug to prevent leakage, and the water agent is equipped with a small hole plug, and the thicker emulsion is equipped with a large hole plug.
The oil bottle is usually a brown or colored scrub, can avoid light, the lid has a safety ring, can be equipped with an inner plug or dropper, and the perfume bottle is generally equipped with a delicate spray pump head or plastic lid.
3.cosmetic glass bottle processing technology
Coloring process
1, electrochemical aluminum: aluminum appearance, a layer of film wrapped in the inner layer of plastic.
2, electroplating (UV) : compared with spraying, the effect is bright.
3, spraying: compared with electroplating color is dark matte.
Spray outside the inner bottle: It is sprayed on the outside of the inner bottle, and there is an obvious gap between the outside and the outer bottle, and the spraying area is small from the side.
Spray inside the outer bottle: It is sprayed on the inside of the outer bottle, which looks larger from the appearance, but is smaller from the vertical plane, and there is no gap with the inner bottle.
4, drawing gold and silver: it is actually a film, careful observation can be found on the bottle to connect the gap.
5, secondary oxidation: It is secondary oxidation on the original oxidation layer, so as to achieve a smooth surface covered with dark matt surface pattern or dark matt surface smooth pattern, which is mostly used in the production of logo.
6, injection color: in the product injection molding in the raw material to add color powder, the process is relatively cheap, you can also add bead powder, adding too white powder will make PET transparent color into opaque color.
