1. Glass bottles used in cosmetics are mainly divided into: skin care products (creams, lotions), perfumes, essential oils, and nail polish. The capacity is small, and the capacity larger than 200ml is rarely used in cosmetics.
2. Glass bottles are divided into wide-mouth bottles and narrow-mouth bottles. Solid pastes generally use wide-mouth bottles, and should be equipped with aluminum or plastic caps. The cap can be used for color spraying and other effects; emulsion or water agent Narrow-mouth bottles are generally used for paste-like bodies, and a pump head should be used. Pay attention to prevent the spring and balls from rusting. Now most pump heads are equipped with glass beads, which are usually tested for the material body. If the cover is equipped with an inner plug, The water agent is equipped with a small hole with the same plug, and the thicker emulsion is equipped with a large hole plug.
3. The selection of glass bottles is relatively consistent, with many shapes, rich processing techniques, and diverse combinations with bottle caps. Common bottle shapes include cylindrical, oval, flat, prismatic, conical, etc., and manufacturers often develop a series of bottle shapes.

4. Silk screen printing: There are usually two kinds of silk screen printing for glass bottles.

5. If the glass bottle is made by hand, there will be a little deviation in the capacity. When selecting, it should be tested and marked with the correct capacity. For example, the automatic production line is relatively uniform, but the shipment requirements are large and the cycle is relatively long. The capacity is relatively stable.
6. The uneven thickness of glass bottles will easily lead to damage, or be easily crushed by the contents in severe cold conditions. A reasonable capacity should be tested during filling, and paper bags should be used for transportation and separated individually. Equipped with a color box, the inner support and the middle box can get more anti-vibration effect.
7. The bottle cap process can be used for anodized aluminum lettering, bronzing edges, and etching lines. There are matte and bright colors. Gaskets and inner caps are required. It is best to use pressure-sensitive sheets to enhance the sealing effect.
