Knowledge of cosmetic packaging materials: Introduction to glass bottles

In the process of skin care product processing, communication with customers will encounter many customers’ questions about cosmetic packaging. Generally, customers are not very familiar with the packaging materials of skin care products, so the cosmetic packaging material processing factory specially sorted out the relevant knowledge as follows: Cosmetic packaging knowledge of glass bottles (cream bottles, essence water, lotion, essential oil bottles) Glass bottles used in skin care products are mainly divided into: skin care products (creams, moisturizing lotions), eau de toilette, single essential oils, nail polish, etc. The volume is small, and the volume exceeding 200ml is rarely used in skin care products. Glass bottles are divided into wide-mouth bottles and narrow-mouth bottles. Solid pastes generally use wide-mouth bottles, and the properties are matched with electroplated aluminum caps or plastic outer caps. The bottle stoppers can be used for color oil pumps and other practical effects; emulsified oils or powder pastes generally use narrow-mouth bottles, which are suitable for pump impellers. If they are matched with outer caps, they must be matched with inner plugs. Powders are matched with small round holes and inner plugs, and thicker moisturizing lotions are matched with perforated inner plugs.

The uneven thickness of glass bottles can easily cause damage, or be easily torn by the contents in cold conditions. The effective volume should be checked during canning, paper bags should be used and separated separately during transportation, and the product should be equipped with color boxes. Packaging, inner support and box can achieve better shock-proof effect.
The common bottle shapes of glass bottles are generally stocked products, such as essential oil bottles, which are generally transparent or frosted bottles. The production cycle of glass bottles is relatively long, usually 20 days, and some delivery times take 45 days. The general purchase quantity is 5,000 to 10,000. The smaller the bottle size, the greater the quantity to be made. The cycle time varies with the starting point. The batch volume is affected by the hot season and the off-peak season. The cost of making abrasive tools: a manual mold costs about 2,500 yuan, an automatic mold generally costs about 4,000 yuan, and 1 out of 4 or 1 out of 8 costs about 16,000 yuan to 32,000 yuan. The actual cost depends on the manufacturer’s standards. Essential oil bottles are generally made of brown or colored plates and colored plate frosted, which can block light. The outer cover has a commercial safety ring and can be equipped with an inner plug or burette. Perfume bottles are generally equipped with exquisite spray pump heads or plastic caps.

Composition

1. Cream bottle series products: glass bottle body + two layers of plastic back cover (generally the volume is 20g-40g)
2. Essence water series products: glass bottle body + plastic pump head or anodized aluminum water pump impeller (the volume is relatively high between 20 and 100ml)
3. Lotion series products: glass bottle body + plastic inner plug + back cover (above 100ml, the type that can also be equipped with a water pump impeller)
4. Essential oil bottle series products: glass bottle body + inner stopper + large cap or plastic dripper + burette + anodized aluminum cap

Processing technology

Bottle body: completely transparent bottle, frosted bottle, colored plate bottle “white porcelain bottle, essential oil bottle” (uncommon colors but high order volume, too few professional lines are used), spray paint
The actual effect of spray paint generally requires an additional 0.5 yuan to 1.1 yuan/piece, depending on the area and color difficulty. Silk screen printing ink is 0.1 yuan/color. Cylindrical bottles can be calculated as solid colors, and special-shaped bottles are calculated as two colors. Or mixed color calculation.
Packaging printing: silk screen ink, hot stamping (it is best not to exceed the frequency of screen printing ink and hot stamping more than twice. Too much overprinting will result in high defective products and high costs)
Screen printing ink: There are generally two types of glass bottle screen printing ink. One is high-temperature ink screen printing ink, which is not easy to fade, the color is dull, and the blue-purple color is difficult to produce actual effects. The other is ultra-low temperature printing ink screen printing ink. , the color is brighter, and the requirements for printing ink are higher, otherwise it will fall off easily, and attention should be paid to the sterilization of glass bottles. Hot stamping and silver hot stamping are 0.5 yuan/style.
