Glass bottle

Glass bottles used in cosmetics are mainly divided into: skin care products (creams, lotions), perfumes, essential oils, and nail polishes. The capacity is small, and the capacity greater than 200ml is rarely used in cosmetics. Glass bottles are divided into wide-mouthed bottles and narrow-mouthed bottles. For solid pastes, a wide-mouthed bottle is generally used. It should be equipped with aluminum or plastic caps. The caps can be used for color spraying and other effects; emulsions or liquid creams The body generally uses a narrow-mouth bottle, preferably with a pump head. If the cap is equipped with an inner plug, the liquid is equipped with a small hole with the same inner plug, and a thicker emulsion is equipped with a large hole inner plug.

The uneven thickness of the glass bottle can easily lead to damage, or it is easy to be squeezed by the content under severe cold conditions. A reasonable capacity should be tested during filling, and paper should be used for transportation and separated separately. The product should be equipped with The color box, the inner support and the middle box can be more anti-vibration effect.

Commonly used glass bottles are usually in stock, such as essential oil bottles, ordinary transparent or frosted bottles. The production cycle of glass bottles is long, it takes 20 days as fast as possible, and some delivery periods take 45 days. Generally, the order quantity is 5,000 to 10,000. The smaller the bottle type, the larger the quantity to be made. The cycle and the minimum order quantity are both Affected by peak season and off-season. Mold opening cost: manual mold is about 2500 yuan, automatic mold is generally about 4,000 yuan, 1 out of 4 or 1 out of 8 costs about 16,000 yuan-32,000 yuan, depending on the manufacturer's conditions. Essential oil bottles are usually made of brown or colored and colored frosted, which can avoid light. The lid has a safety ring and can be equipped with an inner plug or a dropper. The perfume bottle is usually equipped with an exquisite spray pump head or plastic cap.

Combination:

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

2. Essence series: glass bottle body + plastic pump head or anodized aluminum pump head (the volume is relatively high in 20-100ml)

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

4. Essential oil bottle series: glass bottle body + inner plug + large cap or glue dripper + dropper + electrochemical aluminum cap

Bottle body: transparent bottle, frosted bottle and colored bottle 'White Porcelain Bottle, Essential Oil Bottle' (the color is not commonly used but the order quantity is high, and the professional line is rarely used).

Spraying: The effect of spraying generally requires an additional 0.5-3.0 yuan/piece, depending on the area and the difficulty of toning. The silk screen is 0.15 yuan/color. Cylindrical bottles can be calculated in single color, and special-shaped bottles are calculated in double or multi-color .



Printing: silk screen, bronzing, (the number of screen printing and bronzing should not exceed 2 times in total, too much color registration, high defective products and high cost)



cosmetic tube

1. The cosmetic tube is divided into single-layer, double-layer and five-layer cosmetic tubes, which are different in terms of pressure resistance, anti-permeability and hand feeling. For example, a five-layer tube consists of an outer layer, an inner layer, and two adhesive layers. Barrier layer. Features: It has excellent gas barrier properties, which can effectively prevent the infiltration of oxygen and peculiar smell gas, and prevent the leakage of content fragrance and effective ingredients.

2. Double-layer pipes are more commonly used. Single-layer pipes can be used for medium and low-grade pipes. The diameter of the cosmetic tube is 13#-60#. When a certain diameter cosmetic tube is selected, different lengths are used to indicate different capacity characteristics. , The volume can be adjusted from 3ml to 360ml. For aesthetics and coordination, the caliber below 60ml is usually used under 35#. For 100ml and 150ml, the caliber 35#-45# is usually used. For the volume above 150ml, the caliber above 45# is required.

3. The technology is divided into round tube, oval tube, flat tube and super flat tube. Flat tube and super flat tube are more complicated than other tubes. They are also new types of tubes in recent years, so the price is correspondingly more expensive.

4. cosmetic tube caps have various shapes, generally divided into flat caps, round caps, high caps, flip caps, super flat caps, double-layer caps, spherical caps, lipstick caps, plastic caps can also be processed in a variety of processes, bronzing Edge, silver edge, colored cap, transparent, oil spray, electroplating, etc., tip cap and lipstick cap are usually equipped with inner plug. cosmetic tube caps are injection molded products and cosmetic tubes are drawn tubes. Most cosmetic tube manufacturers do not produce cosmetic tube caps themselves.

5. Some products need to be filled before sealing. The sealing is as large as: straight pattern sealing, diagonal pattern sealing, umbrella sealing, star point sealing, special-shaped sealing, and sealing can be required when sealing. Print the required date code at the end.

6. The cosmetic tube can be made of colored tube, transparent tube, colored or transparent frosted, pearl tube, and dumb

The difference between light and bright light, matte looks elegant but easy to get dirty. The difference between the large-area printing of colored tubes and the tube body can be judged from the incision at the tail. The white incision is the 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 cosmetic tube production cycle is generally 15 days to 20 days (from the confirmation of the sample tube). The order quantity of the single product is 50 to 10,000. Large-scale manufacturers usually order 10,000 as the minimum quantity, which is very small. If the manufacturer has a large variety, the single product can be ordered with a minimum order quantity of 3,000. Few customers open the molds by themselves. Most of them are public molds (a few special lids are private molds). There is a deviation of ±10% in this industry.

8. There are big differences in the quality of the cosmetic tube and the price of different manufacturers. The plate-making fee is usually 200 yuan-300 yuan. The tube body can be multi-color printing and silk screen printing. Individual manufacturers have thermal transfer equipment and technology. Hot stamping and hot stamping are calculated based on the unit price of the area. The silk-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:

cosmetic tube + outer cover / cosmetic tube often use PE plastic. According to the thickness of the product, it is divided into single-layer pipe (mostly used, lower cost) and double-layer pipe (good sealing performance). According to the shape of the product, it is divided into round cosmetic tubes (mostly used, lower cost), flat cosmetic tubes are also called special-shaped tubes (requires secondary joints, higher cost). The outer cover of the cosmetic tube is often equipped with screw cap (single layer and double layer, the double-layer outer cover is mostly electroplated cap to increase the product grade, which looks more beautiful, and the professional line usually uses screw cap) and flip cover.

B. Production process:

Bottle body: direct production of plastic products with color, colored and multi-purpose, and some are transparent, which is less used.

Printing: screen printing (use spot colors, small and few color blocks, the same as plastic bottle printing, need to register, professional line products commonly used) and offset printing (similar to paper printing, large color blocks and many colors, daily chemical Thread products are commonly used.) There are bronzing and silver bronzing.



plastic bottle

1. The material of plastic bottle is usually PP, PE, K material, AS, ABS, acrylic, PET, etc.

2. Generally used in cosmetics containers with thicker walls, the cream bottles, caps, stoppers, gaskets, pump heads, dust covers are injection molded; PET blow molding is two-step molding, tube embryo is injection molding, and finished product packaging For blowing. Others, such as lotion bottles and washing bottles with thin container walls, are blown bottles.

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

4. Acrylic is made of injection molding bottle, which has poor chemical resistance. Generally, paste cannot be directly filled. It needs to be equipped with an inner tank to block it. The filling is not easy to be too full to prevent the paste from entering between the inner tank and the acrylic bottle. In order to avoid cracks, the packaging requirements are high during transportation. It looks particularly obvious after scratching, has high permeability, and the sensory upper wall is very thick, but the price is quite expensive.

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

6. Mold development costs: blowing molds are 1500 yuan-4000 yuan, injection molds are 8000 yuan -20000 yuan, molds made of stainless steel are more expensive than alloy materials, but they are durable. Several molds can be produced at a time. The production volume needs, if the production volume is large, you can choose a mold with four or six molds, and the customer can decide by himself.

7. The order quantity is generally 30-10 million, and the color can be customized. Usually, the primary color is frosted and magnetic white, or the pearl powder effect is added. Although the bottle and cap are matched with the same color master, sometimes due to the bottle and cap The materials used are different, and the colors displayed are somewhat different.

8. The screen printing has ordinary ink and UV ink. UV ink has good effect, gloss and three-dimensional effect. You should make a plate to confirm the color during production. The effect of screen printing on different materials will be different.

9. The processing technology of bronzing and silver bronzing is different from that of printing gold powder and silver powder. Hard materials and smooth surfaces are more suitable for bronzing and silver bronzing. The soft surface has poor bronzing effect and is easy to fall off. The gloss of bronzing silver Degree is better than printing gold and silver.

10. Bottle caps are generally equipped with inner gaskets, pull caps, and inner plugs. Very few are equipped with small spoons or droppers. This is mainly due to its tightness and ease of use.

11. The production cycle is relatively moderate, about 15 days. The silk-screened cylindrical bottle is calculated as a single color, 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 unit price is generally 0.2 yuan/color order to 0.1 yuan/color order, the screen version is 100 yuan-200 yuan/model, and the fixture is about 50 yuan/piece.

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

The PP and PETG materials commonly used in injection cream bottle bodies (new materials, transparency, no need to add an inner liner, but there are also double layers, to save costs), acrylic (this product has good transparency, generally add an inner liner, not directly Paste, the bottle body will crack), ABS material (this material is used for electroplating accessories, easy to color), the cover is mostly PP material, the inner cover is PP+ the outer cover is acrylic or the outer cover of electroplating or the outer cover of anodized aluminum or the oil spray cover

Craftsmanship:

Bottle body: PP and ABS bottles use solid colors, PETG materials and acrylic bottles mostly use transparent colors, with a sense of transparency, acrylic bottle walls are mostly spray-colored, which can refract light and have a good effect.

Printing: The bottle body can be silk-screened, gold-plated, and silver-plated. The inner cover of the double-layer cover can be silk-screened, and the outer cover is transparent and shows the effect. The outer cover is made of anodized aluminum, which can strike a convex logo.

(2) Vacuum bottle + pump head cover (essence bottle, toner bottle, lotion bottle), commonly used AS material for injection vacuum bottle body, can directly contact the paste, no straw, vacuum design) + pump head (plating) cover ( Transparent and solid color)

Production process: The transparent color of the airless bottle is more used, and the solid color is less used.

Printing: The bottle body can be silk-screened, gold-plated, and silver-plated.

(3) Bottle blowing

(Essence bottle or lotion bottle, toner bottle) (Production machine: blow molding machine)

A. Understand the blowing process

According to the plastic material, it can be divided into PE blowing (softer uses more solid colors, one-time molding), PP blowing (harder uses more solid colors, one-time molding), PET blowing (good transparency, more use for toner and hair products) , It is an environmentally friendly material, formed twice), PETG bottle blowing (the transmittance is better than PET, but it is not commonly used in China, the cost is high, the cost is high, the one-time forming, non-recyclable materials) are less.

Combination form: bottle blowing + inner plug (commonly used for PP and PE materials) + outer cover (commonly used for PP, ABS and acrylic, and also for electroplating, and anodized aluminum, and oil spray toner) or pump head cover (usually used for essence and lotion) ), + Qianqiu cover + flip cover (Flip cover and Qianqiu cover are mostly used in daily chemical lines in large circulation).

B. Bottle blowing production process:

Bottle body: PP and PE bottle bodies use more solid colors, PETG, PET, PVC materials mostly use transparent colors, or colored transparency, with a sense of transparency, but less solid colors are used. PET bottles can also be sprayed with colors.

Printing: silk screen and hot stamping, hot silver.

(4), pump head

1. Distributors are divided into two types: tie-type and screw-type. In terms of function, they are 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. The spray specification is 12.5mm-24mm, and the water output is 0.1ml/time-0.2ml/time. It is generally used for packaging perfumes, gels and other products. The caliber The length of the same tube can be determined according to the height of the bottle.

3. The size range of the lotion pump is 16ml to 38ml, and the water output is 0.28ml/time -3.1ml/time. It is generally used for creams and washing products.

4. Airless bottles are usually cylindrical, with specifications ranging from 15ml to 50ml, and some have 100ml. The overall capacity is small. It relies on the principle of atmospheric pressure to avoid pollution caused by cosmetics during use. Airless bottles have anodized aluminum, plastic plating and colored Plastics are more expensive than other general containers, and the general order quantity requirements are not high.

5. Multi-use PP material, (production machine: injection molding machine) the outer ring also uses anodized aluminum sleeve, and also uses electroplating process. Gold and silver can also be bronzed.

(1) According to the function of the bottle body:

A. The pump head of the vacuum bottle, without a straw, + outer cover

B. The pump head of an ordinary bottle requires a suction tube. + Cover or no cover.

(2) According to the function of the pump head

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

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

(3) According to the appearance

A. Pump head with cover, the outer cover plays a protective role. (Partially used for products with relatively small volume) within 100ml.

B. The pump head without cover has a special design and can be locked so that the contents will not flow out due to squeezing, which is protective and easy to carry. cut costs. (Partially use products with a comparative capacity.) Above 100ml, most of the pump heads for shower gel and shampoo of the daily chemical line are designed without a cover.

(4) According to the production process

A. Electroplating pump head

B. Anodized aluminum pump head

C. Plastic pump head

(5), outer cover

PP materials are mostly used, but also PS, ABC and acrylic materials. (Production machine: injection molding machine, divided into double cover 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 aluminum outer cover

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

Single layer cover: PP material commonly used

Process: The sides of the cover can be bronzed or silver, sprayed

The inner cover of the double-layer cover can be silk-printed with logo, and the outer cover is transparent and shows the effect. The outer cover is made of anodized aluminum, which can strike a convex logo.

You may have been blinded by the above content, but you don't need to be so professional. General packaging material manufacturers have professional personnel to explain to you. The materials are all different, and I mainly know the difference:

PET: PET has high transparency, the bottle body has softness, can be pinched but 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 more commonly used (easy to squeeze).

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

Acrylics: Thick and hard, acrylic is the most glass-like.
