This is the second chapter in a series of articles on packaging classification in the eyes of purchasing.
This chapter mainly discusses the relevant knowledge of glass bottles.
1. Glass bottles for cosmetics are mainly divided into: skin care products (cream, lotion), perfume, essential oil, nail polish with the capacity lower than 200ml. A large capacity bottle rarely used in cosmetics.
2. Glass bottles are divided into wide mouth containers and narrow mouth containers. Solid paste (cream) is generally used for wide mouth container/jars, which should be equipped with electrochemical aluminum cap or plastic cap. The cap can be used for color injection and other effects; Emulsion or liquid generally used narrow bottle, suitable match with pump head. People should pay attention to prevent spring and ball rust. Most of the pump is equipped with glass beads, usually we need to make material applicable test. If we matching the cover with internal plug, liquid formula need match a small internal plug, thicker emulsion usually match with a big hole plug.
3. The glass bottle has more consistent material selection, more shapes, rich processing technology and diversified matching with the bottle cap. The common bottle types are cylindrical, oval, flat, prismatic, conical, etc. the factory often develops a series of bottle types. The bottle body processes include spraying, transparent, frosting, translucent color matching, silk screen printing, bronzing, etc.
4. If the glass bottle is made by manual mold, there will be a little deviation in capacity. During selection, it shall be tested and correctly marked. The of the automatic production line is relatively uniform, but the shipment requirements are large, the cycle is relatively long, and the capacity is relatively stable.
5. Uneven thickness of the glass bottle may easily lead to damage, or it may be easily crushed by the contents under severe cold conditions. The reasonable capacity shall be tested during filling, and it is recommended to use # outer box for transportation. Skin care products in glass bottles should be equipped with color boxes. If there are inner brackets and medium boxes, they can play a role in earthquake prevention and have higher safety.
6. Common types of glass bottles are usually in stock. The production cycle of glass bottles is longer, 20 days faster, and some are as long as 45 days. For normal glass bottle processing technology, such as customized spraying color and silk screen printing of essential oil bottles, its minimum order quantity is 5000 pcs or 10000 pcs. The smaller the bottle type, the greater the required MOQ, and the cycle and minimum order quantity will be affected by the low season and peak season. Some brown/amber oil bottles and lotion bottles can be shipped on a low MOQ basis, as the supplier has prepared regular stock.
7. Mold opening cost: about $600 for manual mold and about $1000 for automatic mold. A mold with 1 to 4 ot 1 to 8 cavities mold is costs US $3000 to US $6500, depending on the manufacturer's conditions.
8. The bottle cap process can be used for electrochemical aluminum lettering, gilding and line engraving. It can be divided into matte surface and bright surface. It needs to be equipped with gasket and inner cover. It is best to match with sub sensitive film to strengthen the sealing effect.
9. The essential oil bottle usually uses brown, frosted and other colored to avoid light and protect the ingredients. The cover has a safety ring and can be equipped with an inner plug or dropper. Perfume bottles are usually matched with fine mist pumps or plastic caps.
10. Description of process cost: there are usually two kinds of glass screen printing. One is high-temperature ink screen printing, which is characterized by not easy decolorization, dull color and difficult purple color matching. The other is low-temperature ink screen printing, which has bright color and high requirements for ink, otherwise it is easy to fall off. Buyers and sellers need to pay attention to the disinfection methods of such bottles. The cost of silk screen printing is US $0.016 per color. Cylindrical bottles can be used as monochrome plan, and special-shaped bottles are calculated according to the cost of two-color or multi-color. As for spraying, the cost of spraying is generally US $0.1 to US $0.2/color, depending on the area and the difficulty of color matching. The cost of gold and silver stamping is $0.06 per pass.
