Glass bottles

Glass bottles used in cosmetics are mainly divided into skin care products (cream, lotion), perfume, essential oil, nail polish and other categories with small capacity, and those with a capacity of more than 200ml are rarely used in cosmetics. Glass bottles are also divided into wide-mouth bottles and narrow-mouth bottles. Solid pastes are generally wide-mouth bottles, which should be equipped with electrochemical aluminum caps or plastic caps. The caps can be used for color spray and other effects; Emulsion or aqueous paste generally uses narrow mouth bottle, which should be equipped with pump head. If it is equipped with a cover, it needs to be equipped with an inner plug. If it is equipped with an aqueous paste, it needs to be equipped with a small hole as well as an inner plug. If it is thicker, it needs to be equipped with a large hole inner plug.

The uneven thickness of the glass bottle can easily cause damage, or it is easy to be crushed by the contents under severe cold conditions. The reasonable capacity should be tested during filling, and should be held by paper and separated separately during transportation. The color box should be equipped on the product, and the inner support and middle box can better take the anti-vibration effect.

The 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 long, and it takes 20 days to make them quickly. Some delivery periods take 45 days, and the general order quantity is 5000 to 10000. The smaller the bottle type, the larger the quantity to make, and the cycle and the starting order quantity will be affected by the peak season and the off-season. The cost of mold opening: about 2500 yuan for manual mold, about 4000 yuan for automatic mold, and 16000-32000 yuan for 1 out of 4 or 1 out of 8, depending on the manufacturer's conditions. The essential oil bottle is usually brown or colored and colored frosted, which can avoid light. The cover has a safety ring, and can be equipped with an inner plug or dropper. perfume bottles are usually equipped with delicate spray pump heads or plastic covers.

Combination form:

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

2. Essence liquid series: glass bottle body+plastic pump head or anodized pump head (relatively high capacity: 20-100ml)

3. Toner series: glass bottle body+plastic inner plug+outer cover (more than 100ml, can also be equipped with pump head)

4. Essential oil bottle series: glass bottle body+inner plug+large head cap or plastic drip head+dropper+electrochemical aluminum cap manufacturing process:

Bottle body: transparent bottle, frosted bottle, colored bottle "White porcelain bottle, essential oil bottle" (not commonly used color, but high order quantity, less used in professional line).

Spraying: generally, the spraying effect will be added by 0.5 yuan to 3.0 yuan per piece, depending on the area and the difficulty of color matching. The screen printing is 0.15 yuan per color, the cylindrical bottle can be calculated as monochrome, and the special-shaped bottle can be calculated as two-color or multi-color. Printing: silk-screen, bronzing, (the total number of silk-screen and bronzing should not exceed 2 times. Too many colors, high quality and high cost

Hose

1. The hose is divided into single-layer, double-layer and five-layer hoses, which are different in terms of anti-pressure, anti-permeability and hand feeling. For example, the five-layer pipe is composed of outer layer, inner layer, two adhesive layers, and another barrier layer. Features: It has excellent gas barrier performance, which can effectively prevent the infiltration of oxygen and odor gas, and prevent the leakage of the contents, fragrance and effective ingredients.

2. Double-layer tube is more commonly used, and can also be used for medium and low grade. The caliber of the hose is 13 # - 60 #. When selecting a certain caliber of hose, different capacity characteristics are marked with different lengths. The capacity of 3ml - 360ml can be adjusted at will. In order to be beautiful and harmonious, the caliber below 35 # is commonly used for 60ml, the caliber between 35 # and 45 # is usually used for 100ml and 150ml, and the caliber above 45 # is required for 150ml.

3. Technically, it is divided into round tubes, elliptical tubes, flat tubes and ultra-flat tubes. Flat tubes and ultra-flat tubes are more complicated than other tubes, and are also new tubes developed in recent years, so their prices are relatively expensive.

4. The hose covers have various shapes, generally including flat head cover, round head cover, high cover, lift cover, ultra flat cover, double layer cover, spherical cover, lipstick cover, and plastic cover, which can also be processed in a variety of processes, such as hot gilt edge, silver edge, colored cover, transparent, oil spraying, electroplating, etc. The pointed mouth cover and lipstick cover are usually equipped with inner plugs. The hose cap is an injection molding product and the hose is a pull tube. Most hose manufacturers do not produce hose caps themselves.

5. Some products need to be sealed after filling. The sealing can be divided into: straight seal, twill seal, umbrella seal, star seal, and special-shaped seal. The required date code can be printed at the end of the seal.

6. The hose can be made of colored tubes, transparent tubes, colored or transparent frosted tubes, pearlescent tubes, and there is no noise

The difference between light and bright light is that the matte looks elegant but easy to be dirty. The difference between the colored tube and the large area printing of the tube body can be judged from the cut at the tail. The white cut is a large area printing tube, and the ink used is high, otherwise it is easy to fall off and will crack and expose white marks after being folded.

7. The hose production cycle is generally 15 days to 20 days (counting from the confirmation of the sample tube). The order quantity of a single product is 5000 to 10000. Large-scale manufacturers usually order 10000 as the starting quantity. Few small manufacturers can order 3000 for a single product if they have many varieties. Few customers open their own molds. Most of them are male molds (a few characteristic covers are private molds). The contract order quantity and the actual supply quantity have a deviation of ± 10% in this industry.

8. The quality of the hose varies greatly from the manufacturer in terms of price. The plate-making fee is usually 200 yuan to 300 yuan in color. The tube body can be multi-color printed and screen printed. Some manufacturers have thermal transfer equipment and technology. Gold stamping and silver stamping are calculated based on the unit price of the area. The screen printing effect is better, the cost is more expensive and there are fewer manufacturers. Different manufacturers should be selected according to the needs of different levels.

9. Combination form:

PE plastic is often used for hose+outer cover/hose. According to product thickness, it can be divided into single-layer pipe (mostly used, with low cost) and double-layer pipe (with good sealing performance). According to the shape of the product, it can be divided into round hose (mostly used, with low cost) and flat hose, also known as special-shaped pipe (with secondary connector, with higher cost). The outer cover of the hose is usually equipped with a rotary cover (single and double layer, the outer cover of the double layer is mostly electroplated to increase the product grade, which looks beautiful, and the professional line mostly uses a rotary cover) and a lift cover.

B. Manufacturing process:

Bottle body: directly produce plastic products to add color. Colored products are used more often, and transparent ones are also used less.

Printing: screen printing (with spot color, small and few color blocks, and the same way as plastic bottle printing, requiring color registration, and commonly used in professional line products) and offset printing (similar to paper printing, large and many color blocks, and commonly used in daily chemical line products.), as well as gold and silver stamping.

Plastic bottle

1. Plastic bottles are usually made of PP, PE, K, AS, ABS, acrylic, PET, etc.

2. The cream bottle, bottle cap, bottle stopper, gasket, pump head and dust cover, which are usually used for cosmetics containers with thick wall, are injection molded; PET bottle blowing is two-step molding, tube embryo is injection molding, and finished product packaging is bottle blowing. Others, such as lotion bottles and washing bottles with thinner container walls, are blow bottles.

3. PET material is an environmental protection material with high barrier, light weight, non-shattering properties, chemical resistance, and strong transparency. It can be made into pearly, colored, magnetic white, and transparent, and is widely used in gel water. The bottle mouth is generally standard 16 #, 18 #, 22 # and 24 # caliber, which can be used with pump head.

4. Acrylic material is injection molding bottle, which has poor chemical resistance. Generally, it can not be directly filled with paste. It needs to be equipped with inner liner to block it. Filling is not easy to be too full to prevent the paste from entering between the inner liner and the acrylic bottle, so as to avoid cracking. During transportation, the packaging requirements are high, because the scratch looks particularly obvious, the permeability is high, and the upper wall feels very thick, but the price is quite expensive.

5. AS, ABS: AS has better transparency and toughness than ABS.

6. Mold development cost: the bottle blowing mold is 1500 yuan to 4000 yuan, and the injection mold is 8000 yuan to 20000 yuan. The stainless steel material used for the mold is more expensive than the alloy material, but it is durable. The number of molds produced at a time depends on the demand of production. If the production volume is large, you can choose one out of four or one out of six molds, and the customer can decide at his own discretion.

7. The order quantity is generally 3000-10000 pieces, and the color can be customized. Usually, the primary color is frosted and magnetic white, or the effect of adding pearlescent powder. Although the bottles and caps are matched with the same color masterbatch, sometimes the colors are different due to the different materials used for the bottles and caps.

8. There are ordinary ink and UV ink for screen printing. UV ink has good effect, luster and stereoscopic feeling. During production, you should print a plate to confirm the color. The screen printing effect will vary with different materials.

9. The processing technology of bronzing and silvering is different from the effect of printing gold powder and silver powder. The hard material and smooth surface are more suitable for bronzing and silvering. The soft surface is not good for bronzing and easy to fall off. The gloss of bronzing gold and silver is better than that of printing gold and silver.

10. Bottle caps are generally equipped with internal gaskets, pull caps, internal stoppers, and very few are equipped with small spoons or droppers. This is mainly due to their sealing and convenience of use.

11. The production cycle is relatively moderate, about 15 days. The screen printing cylinder bottle is calculated as monochrome, and the flat bottle or special-shaped bottle is calculated as two-color or multi-color. Usually, the first screen printing fee or fixture fee is charged. The screen printing unit price is generally 0.2 yuan/color to 0.1 yuan/color, screen printing 100 yuan - 200 yuan/type, and fixture is about 50 yuan/piece.

(1) Cream bottle+outer cover (production machine: injection molding machine)

PP and PETG materials (new materials, good transparency, no inner liner, but also double layers, to save costs), acrylic (this product has good transparency, generally need to add inner liner, can not directly paste, the bottle will crack), ABS (this material is used for electroplating accessories, easy to color), and the cover is mostly made of PP material, the inner cover is PP+the outer cover is acrylic or electroplated outer cover, or anodized aluminum outer cover or oil injection cover

Manufacturing process:

Bottle body: PP and ABS materials use more solid colors for the bottle body, PETG materials and acrylic bottles use more transparent colors, with a sense of transparency, and acrylic bottle walls use more spray colors, which can refract light, with good effect.

Printing: The bottle body can be screen printed, gilded and silvered. The inner cover of the double-layer cover can be screen printed, and the outer cover can be transparent. The outer cover shall be embossed with aluminum carbide logo.

(2) , vacuum bottle+pump head cover (essence solution bottle, toner bottle, lotion bottle), injection molding vacuum bottle commonly used AS material, can directly contact the paste, no straw, vacuum design)+pump head (electroplating) cover (transparent and solid color)

Production process: use more transparent color for vacuum bottle body and less solid color.

Printing: The bottle body can be screen printed, gilded and silvered.

(3) Bottle blowing

(essence bottle or lotion bottle, toner bottle) (production machine: blow molding machine)

A. Understand the bottle blowing process

According to plastic materials, it can be divided into PE blowing bottles (more solid colors are used than soft ones, forming in one time), PP blowing bottles (more solid colors are used than hard ones, forming in one time), PET blowing bottles (good transparency, more toner and hair products are used, belonging to environmental protection materials, forming in two times), PETG blowing bottles (better transparency than PET, but not commonly used in China, high cost, high consumption, forming in one time, non-recyclable materials) and less.

Combination form: bottle blowing+inner plug (commonly used for PP and PE materials)+outer cover (commonly used for PP, ABS and acrylic materials, but also used for electroplating, anodizing, and spray toner) or pump head cover (commonly used for essence and lotion),+Qianqiu cover+lift cover (mostly used for large circulation daily chemical lines).

B. Bottle blowing process:

Bottle body: PP and PE materials are mostly used in solid color, while PETG, PET and PVC materials are mostly used in transparent color, or colored transparency, with a sense of transparency, and less in solid color. PET bottle body can also be sprayed with color.

Printing: screen printing, bronzing and silvering.

(4) , pump head

1. Distributors can be divided into two types, namely, tie mouth type and screw mouth type. In terms of function, they can be divided into spray, foundation cream, lotion pump, aerosol valve and vacuum bottle

2. The size of the pump head is determined by the caliber of the matching bottle body. The specification of spray is 12.5mm-24mm, and the water output is 0.1ml-0.2ml/time. It is generally used for packaging perfume, gel water and other products. The length of the nozzle with the same caliber can be determined according to the height of the bottle body.

3. The lotion pump has a wide range of specifications from 16ml to 38ml, and the water output is 0.28ml/time to 3.1ml/time. It is generally used for cream and washing products.

4. Vacuum bottles are usually cylindrical, with the specification of 15ml-50ml, and some of them are 100ml. The overall capacity is relatively small. It is based on the principle of atmospheric pressure, which can avoid the pollution caused by cosmetics in the process of use. Vacuum bottles include aluminum carbide, plastic electroplating and colored plastic. The price is more expensive than other ordinary containers, and the general order requirements are not high.

5. Polypropylene material is widely used. (Production machine: injection molding machine) The outer ring is also made of anodized aluminum sleeve, and electroplating process is also used. You can also iron gold and silver.

(1) According to the function of the bottle:

A. Pump head of vacuum bottle, without straw,+cover

B. The pump head of ordinary bottle needs a suction pipe+ Cover or no cover.

(2) According to the function of pump head

A. Lotion pump head (suitable for lotion like contents, such as lotion, shower gel, shampoo)

B. Spray pump head (content suitable for water properties, such as spray, toner)

(3) According to appearance

A. The pump head is covered and the outer cover is used for protection. (Mainly used for products with small capacity) within 100ml.

B. The pump head without cover, with special design, can be locked, and will not squeeze out the contents, which is protective and easy to carry. Reduce costs. (Products with relatively large capacity are preferred.) For more than 100ml, the pump head design of shower gel and shampoo in the daily chemical line is mostly without a cover.

(4) According to the manufacturing process

A. Electroplating pump head

B. Aluminized pump head

C. Plastic pump head

(5) Outer cover

PP materials are widely used, including PS, ABC and acrylic materials. (Production machine: injection molding machine, divided into double covers according to structure:

A. PP inner cover+PS and acrylic outer cover

B. PP inner cover+outer cover PP, ABS material electroplating

C. PP inner cover+anodized outer cover

D. PP inner cover+PP or ABS fuel injection outer cover

Single-layer cover: commonly used for PP material

Process: cover edges can be gilded or silvered and sprayed with oil

The inner cover of the double-layer cover can be screen printed with logo, and the outer cover can be transparent. The outer cover shall be embossed with aluminum carbide logo.

You may have been blinded by the above content, but you don't need to know that it is so professional. General packaging material manufacturers have professional staff to explain it to you. The materials are different. I mainly know the differences:

PET: PET has high transparency, the bottle body is soft and can be squeezed concave, but it is harder than PP.

PP: PP bottles are softer than PET, easier to pinch, and less transparent than PET, so some opaque shampoo bottles are commonly used (easy to squeeze).

PE: The bottle body is basically opaque and not as smooth as PET.

ACRYLICS JACK: It's thick and hard. The most glass-like thing is acrylic.
