On the packaging of liquid cosmetics

according to the different fluidity of liquid cosmetics, it can be roughly divided into liquid cosmetics, lotion cosmetics and cream cosmetics. This article discusses some problems involved in the packaging of liquid cosmetics, such as packaging materials, packaging forms, packaging materials and the printing methods of containers, in the hope that readers can have an overall understanding of the packaging of this kind of cosmetics

there are many kinds of liquid cosmetics, such as nail (toenail) oil and nail washing water; Hair coloring water, gel water, hair gel and hair mousse (aerosol hair conditioner); All kinds of makeup water (such as toner, prickly heat water, firming water, moisturizer); Perfume, essence and so on are liquid cosmetics

liquid cosmetics are easy to penetrate or overflow (such as toner, hair gel water, etc.), and some have strong volatility (such as perfume and essence, which are easy to lose fragrance), and even contain organic solvent components (such as nail polish, nail washing water, etc.). When packaging this kind of cosmetics, in view of its permeability, volatility, or containing organic solvents and other special properties, packaging materials and containers are required to have good barrier performance and sealing performance, and sometimes they are also required to have certain solvent resistance (such as the packaging of nail polish); In view of the characteristics of good liquid fluidity, easy overflow and easy access by dumping the container, it is required that the opening of the packaging container should not be too large, and the sealing between the container and the cover should be good. Sometimes, special bottle mouth design is also required to facilitate use and be conducive to saving, such as the packaging of high-end perfume

for the packaging of liquid cosmetics, the commonly used packaging containers are mainly small caliber glass bottles and plastic bottles of various shapes. Plastic caps are generally used, and functional designs are carried out, such as movable dumping caps, hinged plug hole caps, etc., for convenience of use. For some special liquid cosmetics, special packaging forms are often used, such as the packaging of hair mousse, hair gel and hair gel water, and the form of spray packaging is often used

commonly used packaging materials

the packaging materials commonly used in liquid cosmetics mainly include glass materials, plastic materials, high-grade cardboard, etc. Among them, glass materials are mainly used to manufacture glass bottles and cans of various sizes and structural shapes; Plastic materials such as polypropylene and polystyrene are often used to make plastic bottles of various shapes, and polypropylene is also often used to make bottle caps of various shapes; High grade paperboard is often used to make paper boxes with exquisite printing, elegance and chic. As the outer package of liquid cosmetics, it forms a sales package together with plastic bottles or glass bottles

common packaging forms

plastic bottle packaging

plastic bottles have small proportion, are easy to color, and have strong plasticity. They can be made into bottle types of various shapes, and the price is low, which is suitable for large-scale production. In order to increase the decorative effect of plastic bottles, in addition to bottle printing, coloring materials can also be added during production to make bottles of various colors. Metal steaming dyeing, gold plating and thermal printing can also be used for surface decoration to meet the needs of different grades of packaging. Plastic bottles commonly used for packaging cosmetics mainly include polyethylene bottles (blow molding), polyvinyl chloride bottles (injection molding, stretch blow molding), polyester bottles (stretch blow molding), polystyrene bottles (injection molding), polypropylene bottles (extrusion blow molding), etc

plastic bottles used for the packaging of liquid cosmetics are generally small mouthed bottles, which are mainly used to pack all kinds of makeup water, such as toner, prickly heat water, firming water, moisturizer, etc. Lower grade perfume (such as Cologne Perfume, also known as cologne water, the content of essence is generally 2 ~ 5%, and strict regulatory requirements ensure the safety of this utilization field. The alcohol concentration is 75 ~ 85% or 70 ~ 85%. Sometimes, they are also packed in plastic bottles (or equipped with spray devices and color printing cartons). Generally, the volume of the bottles is large. Polypropylene bottles (cans) can be used for spray packaging of perfume and essence. Hair gel water is also commonly packaged in plastic spray cans

when plastic bottles are used to pack all kinds of cosmetic water, the bottle type, color, transparency and various decorations used vary a lot, so as to highlight the characteristics of products and promote sales. For example, when using transparent plastic bottles for packaging, generally only simple line printing is carried out to highlight the clear and transparent characteristics of products to attract consumers; When plastic bottles of various colors are used for packaging, they are usually decorated by printing or pasting labels on the bottle body to convey the product information and win the favor of consumers; Carry out the modeling design of novel bottle shape and bottle cap, and cooperate with the design of the bottle body to show the characteristics of the product, so as to arouse consumers' curiosity and stimulate consumers' desire to buy; Sometimes, color printing cartons, windowed cartons and plastic bottles are used to form a sales package

plastic bottles are used for the packaging of liquid cosmetics. The container molding and processing is relatively simple and convenient, and it is easy to change the color and transparency of the bottle. Various methods can be used for surface decoration, which is suitable for large-scale production, with low comprehensive cost, and can better meet people's needs

glass bottle packaging

load sensor force measuring glass bottle has good chemical stability and is not easy to react with its contents; With good transparency, colorants such as iron, cobalt and chromium can be added to the raw materials to produce glass bottles of various colors (such as amber glass, green glass, cyan white glass, cobalt blue glass, milky white glass and opaque glass); Good heat resistance and not easy to deform; High compressive strength and internal pressure resistance; High density and weight (suitable for high-end cosmetics packaging); Good barrier, sanitation and preservation, easy to seal, and can be tightly sealed again after opening. But at the same time, the impact resistance of glass bottles is poor, fragile, the filling cost is high, and the molding process is complex, which limits the application of glass bottles. Glass bottles are often used in the packaging of high-end cosmetics or cosmetics with special requirements

glass bottles used for the packaging of liquid cosmetics are generally small mouth bottles (narrow mouth bottles), which are mainly used for the packaging of nail polish, nail washing water, perfume and essence. The structure and shape of glass bottles can be designed according to the needs of product packaging, and can be achieved by changing the mold during manufacturing. The bottle body can be directly decorated by printing or labeling. At the same time, glass bottles of different colors can be selected to meet the packaging requirements of cosmetics with different characteristics. The design of bottle cap matching with glass bottle is a very important aspect, especially the design of perfume bottle and bottle cap, which is ever-changing

glass bottle packaging of nail polish

small glass bottles with beautiful shapes are generally used for the packaging of nail polish. Because the ingredients of nail polish contain pigments, precipitation will occur after long-term storage, so the bottle cap is generally designed as a bottle cap with a small brush and easy to hold and brush, so as to facilitate the use of a certain amount of nail polish and brush it to the appropriate position of the nail. At the same time, the ingredients of nail polish also contain solvents, which are easy to volatilize. Glass bottles with good barrier performance are selected for packaging, and the bottle cap and bottle body are closely matched and sealed, which is conducive to the quality assurance of nail polish

in addition, small glass bottles used for packaging nail polish are generally made of transparent glass, and directly reveal the color of nail polish. At the same time, simple trademark patterns are printed on the appropriate parts of the bottle to identify different brands. The shape design of the bottle cap should be perfectly combined with the bottle shape, giving people the enjoyment of beauty, so as to stimulate consumers' desire to buy

glass bottle packaging of perfume and essence

perfume and essence are liquid fragrances commonly used in daily life, both of which have fragrant, rich and lasting aroma. They are generally packaged in glass bottles to meet the requirements of their packaging and noble characteristics. Some lower grade perfume (such as Cologne Perfume) can also be packaged in plastic bottles

glass bottles used for packaging perfume and essence are rich and diverse in shape. Generally, transparent glass bottles of various colors are used for packaging, and various patterns are often made during bottle body processing to increase the decorative effect of the bottle body; The bottle size specification changes according to the characteristics, requirements and grades of perfume and essence inside; The design of the bottle cap has good sealing performance and beautiful and changeable shape, which can play a good decorative role; Generally, the bottle body is not printed with a pattern (even if the pattern is printed, the pattern is small, and does not affect the overall display effect of the bottle), but shows the clear and transparent characteristics of the product. Trademarks and patterns are usually printed on the bottle cap, or nameplate signs are hung on the bottleneck. Typical bottle shape and cap design mainly include:

① general bottle shape design and bottle mouth design, together with functional bottle caps (such as various dumping caps), which are dumped and dipped directly by hand. The perfume packaged in this way is of low grade (such as the packaging of Cologne Perfume), with large bottle capacity and low packaging cost, which is suitable for the consumption of the public

② the bottle type with novel and beautiful structure and shape design is adopted, and the design of the bottle cap is also unique. It cooperates with the bottle type to form the packaging of perfume and essence, reflecting the high-grade of the contents and giving people a sense of elegance (such as the packaging design of "fan-shaped bottle cap with half moon shaped bottle body" commonly seen in the market); At the same time, the bottle mouth is equipped with a spray device to facilitate quantitative and directional access to achieve the purpose of saving. In addition, the sales package is also equipped with appropriate cartons with elegant and chic printing. This packaging method is suitable for the packaging of high-grade perfume and essence, and the sales target is people with high consumption ability

③ revitalize the packaging design of "zouzhu" perfume in non operating assets. The packaging form of perfume known as "walking beads" in the market is actually named according to the characteristics of the mouth structure of perfume bottles. The bottle type used in this packaging form is generally a cylindrical transparent glass bottle with smaller specifications and sizes, and the bottle mouth is covered with a "polyethylene rolling inner cap", and the outer cover is covered with a layer of plastic or metal screw cap. The rolling inner cover is actually a small ball made of fastened polyethylene (or polycarbonate, polypropylene). Most of the ball is pressed into the cover (which can rotate). When using, turn the bottle upside down, and perfume will wet the inner surface of the ball. Then, contact the ball with the part where perfume is to be used and roll it slowly, and then apply perfume to the predetermined position. Due to the strong volatility of perfume, glass bottles are often equipped with soft plastic seat rings, so that when the screw cap presses the ball, it can ensure that the bottle has a good sealing effect and avoid the volatilization of perfume. The design of this perfume bottle usually prints simple pattern marks on the outer cover of the bottle, rarely on the bottle body. In this design form, in addition to using glass bottles, sometimes polyethylene plastic bottles can also be used (usually for decoration and printing), and the mouth and bottom of the plastic bottles are directly formed into one, and other structures are basically the same as those of glass bottles, which are generally used for the packaging of perfume with high viscosity

common printing methods

printing of plastic bottles and plastic caps

the surface decoration of plastic bottles can be printed by a variety of printing methods in addition to various processing methods in the manufacturing process. The commonly used printing methods mainly include silk printing, transfer printing (pad printing) and letterpress offset printing (especially mass printing, and the bottle type is relatively simple); The printing of bottle caps can also adopt silk printing and transfer printing. For bottle caps used with glass perfume bottles, sometimes
