Lotion bottle manufacturing process
Lotion bottles can be divided into plastic materials
PE bottle blowing (softer, more solid colors, one-time molding)
PP blow bottle (harder, more solid colors, one-time molding)
PET bottle (good transparency, mostly used for toner and hair products, environmentally friendly materials, secondary molding)
PETG bottle blowing (brightness is better than PET, but not commonly used in China, high cost, high cost, one-time molding, non-recyclable materials)
Bottle body: PP and ABS bottles are mostly solid colors, PETG and acrylic bottles are mostly made of transparent colors, which have a sense of translucency, and the walls of acrylic bottles are mostly spray-painted and reflective.
Lotion bottle printing: The body of the bottle can be screen printed, hot stamped, or silver hot. The inner cover of the double-layer cover can be screen printed, and the outer cover can be transparent. The housing is made of anodized aluminum and can be embossed with a logo.
1. Vacuum bottle + pump head cap (essence bottle, toner bottle, lotion bottle)
Injection vacuum bottle is usually made of AS material, which can directly contact the paste, no straw, vacuum design) + pump head (electroplating) cover (transparent solid color)
Production process: The transparent color of the vacuum bottle body is mostly used, and the pure color is rarely used.
Printing: The body of the bottle can be screen printed, hot stamped, or silver hot.
2. Bottle blowing (essence bottle or lotion bottle, toner bottle) (production machine: blow molding machine)
Understanding the Blowing Process
According to the plastic material, lotion bottles can be divided into PE blow bottles (softer, more solid colors, one-time molding), PP blow bottles (harder, more solid colors, one-time molding), PET bottles (good transparency, mostly used for toner and hair products), It is an environmentally friendly material, secondary molding), PETG blow bottle (brightness is better than PET, but it is not commonly used in China, high cost, high cost, one-time molding, non-recyclable material). Combination form: bottle blowing + inner plug (often used in PP, PE materials) + outer cover (often used in PP, ABS, acrylic, also electroplating, anodized aluminum, mostly used for fuel injection toner) or pump head cover (often used in Essence and lotion), + Qianqiu cap + Flip lid (lifting cap and Qianqiu cap are mostly used in large-scale circulation daily chemical lines).
Blowing production process:
Bottle body: PP and PE bottles are mostly made of solid colors, and PETG, PET, and PVC bottles are mostly made of transparent colors, or colored and transparent, with a sense of translucency, and less solid colors are used. The PET bottle body is also available in spray colors.
Printing: screen printing, hot stamping, hot silver.
There are two types of dispensing machines: cable tie type and spiral type. In terms of function, it can be divided into spray, foundation cream, lotion pump, aerosol valve, and vacuum bottle.
The size of the pump head is determined by the caliber of the matching bottle. The spray size is 12.5mm-24mm, and the water output is 0.1ml/time-0.2ml/time. Generally used for the packaging of perfume, gel water and other products. The length of the same nozzle can be determined according to the height of the bottle.
The specifications of the lotion pump range from 16ml to 38ml, and the water output is 0.28ml/time-3.1ml/time. It is commonly used in face creams and wash products.
Vacuum bottles are generally cylindrical, with specifications of 15ml-50ml, and some are 100ml, and the overall capacity is small. It relies on the principle of atmospheric pressure to avoid pollution caused by cosmetics during use. Vacuum bottles are available in anodized aluminum, electroplated plastic and colored plastic, the price is more expensive than other common containers, and the general order quantity requirement is not high.
4. PP material is commonly used, (production machine: injection molding machine) the outer ring is also made of anodized aluminum sleeve, and electroplating process is also used. It can also be gold and silver plated.
According to the function of the bottle body:
A. Pump head for vacuum bottle, without straw, + cap
B. The pump head of an ordinary bottle needs a straw. + With or without cover.
According to the function of the pump head
A. Lotion bottle pump head (suitable for lotion content, such as lotion, shower gel, shampoo)
B. Spray pump head (suitable for water-based content, such as spray, toner)
by appearance
A. The pump head of the lotion bottle has a cover, which plays a protective role. (It is more suitable for products with relatively small capacity) within 100ml.
B. The special design of the capless pump head can be locked, and the contents will not flow out due to extrusion, which plays a protective role and is easy to carry. Reduce expense. (Priority is given to products with relatively large capacity.) More than 100ml, the pump heads of shower gel and shampoo on the daily chemical production line are mostly designed without a shell.
According to production process
A. Plating pump head
B. Anodized aluminum pump head
C. Plastic pump head
