1. The packaging bottles used in cosmetics are mainly divided into: skin care products (creams, lotions), perfumes, essential oils, nail polishes, etc. Cosmetics with a small capacity and a capacity greater than 200ml are rarely used.
2. Cosmetic bottles are divided into wide-mouth bottles and narrow-mouth bottles. Solid paste is generally used in wide-mouth bottles with aluminum or plastic caps. Bottle caps can be used for color spraying and other effects; for emulsions or liquid pastes, narrow-mouth bottles are generally used, and a pump head should be used. Take care to prevent the springs and balls from rusting. Most pump heads are now equipped with glass beads, which are often used for bulk inspection of materials. For example, a lid needs to be equipped with an inner plug. The small holes are the same as the inner plugs for aqueous solutions, the larger holes are used for thicker emulsions.
3. Plastic bottles are more consistent in material selection, more shapes, rich in processing technology, and diversified with bottle caps. Common bottle shapes include cylindrical, oval, flat, prismatic, and conical. Manufacturers often develop a range of bottle formats. The bottle body process includes spraying, transparent, frosted, translucent toning, silk screen printing, hot stamping, hot silver.
4. Silkscreen: There are usually two types of silkscreens for plastic bottles. One is high-temperature ink screen printing, which is not easy to decolorize, the color is dull, and it is not easy to produce a purple tone. The other is low temperature ink screen printing with more vivid colors. The ink has high requirements, otherwise it will fall off easily. Pay attention to the disinfection of the bottle.
5. The spraying effect generally requires an additional charge of 0.5 yuan to 1.1 yuan per piece, depending on the area and the difficulty of color matching. Silk screen printing is 0.1 yuan/color. Cylindrical bottles can be calculated as single-color, and special-shaped bottles can be calculated as two-color or multi-color. , bronzing silver 0.4 yuan / paragraph.
6. If the plastic bottle is made by hand mold, the capacity will have a little deviation. When selecting, the test should be carried out and the correct capacity should be marked. For example, the automated production line is relatively uniform, but the shipment volume is relatively large and the cycle is relatively long. The capacity is relatively stable.
7. The uneven thickness of the packaging bottle is easy to cause damage, or it is easy to be squeezed by the contents under severe cold conditions. A reasonable volume should be tested when filling. Packaging should be carried by paper and separated separately. The product should be equipped with a color box, and the inner support and the middle box can play a more shock-proof effect.
8. The commonly used bottle types of packaging bottles are generally available in stock, such as essential oil bottles, ordinary transparent or frosted bottles, etc. The production cycle of glass bottles is long, the fastest takes 20 days, and some supply cycles take 45 days. The general order quantity is 5,000 to 10,000 pieces. The smaller the bottle type, the larger the quantity made. Cycle time and minimum order quantity will be both. Affected by high and low seasons.
9. The cost of mold opening: manual mold opening is about 2,500 yuan, and automatic mold opening is generally about 4,000 yuan.
10. The bottle cap process can be used for electrochemical aluminum lettering, bronzing, and etching lines. Available in matte and bright colors. It must be equipped with a gasket and an inner cover. It is best to use a pressure sensitive sheet for enhanced sealing.
11. Essential oil bottles are generally brown or colored and matte, which can be protected from light. The cap has a safety ring and can be fitted with an inner stopper or dropper. Perfume bottles usually come with fancy spray pumps or plastic caps.
