1. The packaging bottles used in cosmetics are mainly divided into: skin care products (creams, lotions), perfumes, essential oils, nail polish, 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 pastes are generally used in jars with aluminum or plastic caps. The bottle cap can be used for color spraying and other effects; for emulsion or liquid paste, a narrow-mouth bottle is 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, often used for batch inspection of materials. For example, the 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 in caps. Common bottle shapes include cylindrical, oval, flat, prismatic, and conical. Manufacturers usually develop a range of bottle shapes. 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 dim, and it is not easy to produce purple tone. The other is low temperature ink screen printing with more vivid colors. The ink requirements are high, otherwise it is easy to fall off. Pay attention to the sterilization of feeding bottles.
5. The spraying effect generally requires an additional charge of 0.5-1.1 yuan/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 a 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, there will be a little deviation in the capacity. The test should be carried out when selecting, and the correct capacity should be marked. For example, the automated production line is relatively unified, 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 in paper packaging and separated. The product should be equipped with a color box, and the inner support and the middle box can play a better shockproof effect.
8. Commonly used bottle-type 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 delivery cycles take 45 days. Typical order quantities are 5,000 to 10,000 pieces. The smaller the bottle size, the greater the yield. Cycle time and minimum order quantity will be both. Affected by high and low seasons.
9. The cost of mold opening: about 2,500 yuan for manual mold opening, and about 4,000 yuan for automatic mold opening.
10. The bottle cap process can be used for anodized 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 to enhance the seal.
11. The essential oil bottle is generally brown or colored matte, which can be protected from light. The cap has a safety ring that can fit an inner plug or dropper. Perfume bottles usually come with fancy spray pumps or plastic caps.
