Cosmetic packaging material knowledge glass bottles (cream bottles, essences, toners, essential oil bottles)

Glass bottles are mainly used in cosmetics: skin care products (creams, lotions), perfumes, essential oils, and nail polish. The bottles have smaller capacities. Capacities larger than 200ml are rarely used in cosmetics. Glass bottles are divided into wide-mouth bottles and narrow-mouth bottles. Solid pastes generally use wide-mouth bottles. They should be equipped with an aluminum cap or a plastic cap. The cap can be used for color spraying and other effects; emulsion or aqueous pastes Bottles generally use narrow-mouth bottles, which should be equipped with pump heads. If equipped with a lid, it must be equipped with an inner stopper. For aqueous solutions, it must be equipped with a small hole and the same inner stopper. For thicker emulsions, it must be equipped with a large hole inner stopper.

The following is a detailed introduction to cosmetic glass bottles:

一、Materials and characteristics of glass bottles

• Material: Glass bottle is mainly formed by melting silica and other chemical substances. It is a silicate non-metallic material. Its main component is silicate double salt, which is lead-free, harmless, safe and hygienic.

• Features:

1. Good barrier performance: It can effectively prevent various gases from oxidizing and corroding the objects inside the bottle, and at the same time prevent the volatile components of the objects inside from evaporating.

2. Corrosion resistance and acid corrosion resistance: It has good corrosion resistance and acid corrosion resistance, and has special packaging advantages for the cosmetics industry.

3. Recyclable and reusable: Glass bottles can be recycled and used multiple times, reducing corporate packaging costs and also benefiting the environment.

4. High transparency: The glass bottle is transparent and the content inside is clearly visible, conveying a sense of high-end to consumers.

二、Classification and uses of glass bottles

• Classification: According to the type of bottle mouth, glass bottles can be divided into wide-mouth bottles and narrow-mouth bottles.

1. Wide-mouth bottles: Mostly used for solid paste cosmetics such as facial creams and smear-type masks.

2. Narrow-mouth bottle: generally used for aqueous and emulsion cosmetics.

• Purpose: Glass bottles are mainly used in cosmetics for skin care products (creams, lotions), perfumes, essential oils, nail polish and other smaller products. Capacities greater than 200ml are rarely used in cosmetics, mainly due to weight and ease of use.

三、Glass bottle processing technology and decoration

• Processing technology: The body of the glass bottle can be processed by various processes such as frosting, spraying, and silk screen printing. These processes not only enrich the appearance of the glass bottle, but also improve its protective properties.

1. Frosted: Increase the texture of the bottle and improve anti-slip performance.

2. Spraying: Various colors or patterns can be sprayed on the surface of the bottle to enhance the visual effect of the product. Spraying effects generally require additional charges, and the cost depends on the area and difficulty of color mixing.

3. Silk screen printing: divided into two types: high temperature ink screen printing and low temperature ink screen printing. High-temperature ink screen printing is not easy to fade, and the color is dull; low-temperature ink screen printing has a brighter color, but has higher requirements for ink, otherwise it will easily fall off.

• Decoration: The bottle cap process can be decorated with anodized aluminum lettering, hot stamping edges, etched lines, etc. to enhance the quality of the product.

The uneven thickness of glass bottles can easily lead to damage, or they can be easily squeezed by the contents under severe cold conditions. Reasonable capacity should be tested during filling, and paper bags should be used and separated individually during transportation. Products should be equipped with The color box, inner support and middle box can achieve better anti-vibration effects.

Commonly used bottle shapes of glass bottles are usually in stock, such as essential oil bottles, ordinary transparent or frosted bottles. The production cycle of glass bottles is longer, and it can take up to 20 days at the earliest. Some delivery times take 45 days. The general order quantity is 5,000 to 10,000. The smaller the bottle, the greater the quantity. The cycle and the minimum order quantity will be different. Affected by peak season and off-season. Mold opening cost: A manual mold costs about 5,000 yuan, an automatic mold generally costs about 8,000 yuan, and 1 out of 4 or 1 out of 8 costs about 32,000 yuan, depending on the manufacturer's conditions. Essential oil bottles are usually brown or colored or colored frosted, which can be protected from light. The lid has a safety ring and can be equipped with an inner stopper or a dropper. Perfume bottles are generally equipped with a delicate spray pump head or a plastic cap.

       Combination form:

　　1、 Cream bottle series: glass bottle body + double-layer plastic outer cover (generally capacity is 10g-50g)

       2、 Essence series: glass bottle + plastic pump head or anodized aluminum pump head (capacity is relatively high at 20 to 100ml)

       3、 Toner series: glass bottle + plastic inner plug + outer cap (100ml or more, the kind with a pump head is also available)

       4、 Essential oil bottle series: glass bottle + inner plug + large cap or plastic dripper + dropper + anodized aluminum cap

       Production process:

　　Bottle body: transparent bottle, frosted bottle, colored bottle "white porcelain bottle, essential oil bottle" (colors are not commonly used but the order quantity is high, and they are rarely used in professional lines)

       Spraying: The spraying effect generally requires an additional 1.1 yuan/piece, depending on the area and color adjustment difficulty. Silk screen printing is 0.2 yuan/color. Cylindrical bottles can be calculated as single color, and special-shaped bottles are calculated as double or multi-color.

　　Printing: silk screen printing, hot stamping (it is best not to exceed 2 times in total for screen printing and hot stamping. Too many colors will lead to high defective products and high costs)

      Silk screen printing: There are usually two types of glass bottle screen printing. One is high-temperature ink screen printing, which is characterized by not easy to fade, the color is dull, and purple coloring is difficult to achieve. The other is low-temperature ink screen printing, which has a brighter color and is not suitable for inks. The requirements are relatively high, otherwise it will fall off easily, and attention should be paid to sterilizing the bottle. Hot stamping and silver stamping are 1 yuan/style.
