Guangzhou Wengu Plastic Co., Ltd. talks about cosmetic tube packaging for beauty salons

With the continuous improvement of living standards, people pay more and more attention to the beauty of life. The premise of life beauty is healthy and beautiful skin, and healthy and beautiful skin starts with clean skin. Facial cleansers currently on the market generally include soap, foam cleanser, cleansing gel, facial cleanser and so on. Careful friends will certainly find that most of the current cleansing products are packaged in plastic tubes, which are also called tube packaging in the packaging industry. In fact, tube packaging is not only used in cleansing products, but also widely used in daily necessities such as hair conditioner, hand cream, toothpaste, BB cream, and beauty salon cosmetics; it is also used in medical supplies, such as various ointments. , It is also widely used in food packaging such as jelly, jam, meat sauce and so on abroad.

　　

We can define a hose in this way. A hose package is a flexible packaging container used to pack liquid products with a paste or high viscosity.

　　

The tube packaging has the characteristics of light weight, easy to carry, sturdy and durable, recyclable, easy to squeeze, good processing performance and printing adaptability; at the same time, it is relatively cheap compared to plastic bottle packaging, which may be the result of many beauty salon cosmetic manufacturers The reason for favor. If you have a deep understanding of cosmetic hoses in beauty salons, you will find that there is really too much content to expand. With the help of Hongxin Packaging as an exchange platform, I would like to have a brief discussion with you on plastic hose materials, filling technology and future trends.

　　The overall structure and function of plastic hose

　　

　　

An ordinary hose can be divided into tail (A), tube (B), tube shoulder (C), hose head (D) and hose cover (E).

　　

Tube tail (A): According to different market needs, it can be made into straight, diagonal, umbrella, star point, special-shaped, and various shapes. Its main purpose is to increase the shelf display effect. , Arouse the attention of consumers, thereby enhancing sales competitiveness. The general production date code is also printed at the end of the tube.

　　

　　 Tube body (B): The main body of the hose, the carrier of information, the material and characteristics of the tube body will be introduced in detail later in the article.

　　

　　Tube shoulder (C): The connection part of the hose head and the tube. When making the design drawings, pay attention to leaving a connection space, generally 3mm.

　　

　　 Hose head (D): There are different shapes and different shapes of caps to match. The discharge hole of the pipe head needs to be paid attention to. Generally, the pore size is reasonably selected according to the viscosity of the material to achieve the most complete use effect. If the fluidity of the material is very good, it is necessary to select a small-diameter discharge hole; on the contrary, for a paste-like material, it is necessary to appropriately select a discharge hole with a larger diameter.

　　

Hose cap (E): Hose 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, and plastic caps. Various processes are also available. Top treatment, bronzing edging, silver edging, colored cover, transparent, oil spraying, electroplating, etc., pointed mouth cover. Hose caps are injection molded products and hoses are drawn tubes. Most hose manufacturers do not produce hose caps themselves.

　　

　　Plastic hose body material and its characteristics

　　

　　Plastic hoses commonly used in cosmetic packaging in beauty salons are classified according to material application and processing technology. They can be divided into aluminum-plastic composite hoses, all-plastic composite hoses and plastic co-extruded hoses.

1.Aluminum-plastic composite hose

　　

　　Aluminum-plastic composite hose is a kind of packaging container made of aluminum foil and plastic film through a co-extrusion composite process, and then processed into a tube by a special pipe-making machine. Its typical structure is PE/PE+EAA/AL/PE +EAA/PE. Aluminum-plastic composite hoses are mainly used for packaging beauty salon cosmetics that require high hygiene and barrier properties. The barrier layer is generally aluminum foil, and its barrier properties depend on the pinhole of the aluminum foil. With the continuous improvement of technology, the thickness of the aluminum foil barrier layer in the aluminum-plastic composite hose has been reduced from the traditional 40μm to 12μm, or even 9μm, which greatly saves resources. High barrier properties are the characteristics of aluminum-plastic composite hoses. Aluminum foil has barrier properties such as light blocking, oxygen blocking and water blocking, which can prevent foreign substances from intruding into the beauty salon cosmetics, prevent the beauty salon cosmetics from oxidizing and deteriorating, and at the same time prevent the moisture or fragrances in the beauty salon cosmetics from diffusing through the hose To the outside world, so as to ensure the quality of cosmetics in beauty salons. However, the disadvantage is that aluminum-plastic composite hoses have many disadvantages due to the use of aluminum foil, such as invisible content, poor environmental protection, poor resilience, lower composite strength than all-plastic composite hoses, and easy delamination.

　　

　　2. All-plastic composite hose

　　

　　All-plastic composite hoses are all plastic components, and are divided into two types: all-plastic non-barrier composite hose and all-plastic barrier composite hose. The barrier layer can be a multilayer composite material containing EVOH, PVDC, oxide-plated PET, etc. The typical structure of all-plastic barrier composite hose is PE/PE/EVOH/PE/PE。

　　

　　Compared with aluminum-plastic composite hoses, all-plastic composite hoses are more environmentally friendly and easy to recycle. Better resilience ensures that after squeezing the cosmetics in the beauty salon, the hose can quickly return to its original shape and always maintain a beautiful and regular appearance. Because it is a plastic sheet composite process, printing decoration can be diversified. Flexographic printing can be selected according to the size of the demand. You can choose gravure printing according to the complexity of the artwork, or you can choose surface printing or inside printing according to functional requirements ( The printing layer is on the side of the composite layer). According to the characteristics of cosmetics in beauty salons and different consumer needs, the all-plastic composite hose can be made into different colors, such as colorless and transparent, color transparent, color opaque, etc., which brings strong visual impact to consumers. But the disadvantage is that the all-plastic barrier, non-barrier composite hose is usually used for the packaging of cosmetics in middle and low-end beauty salons due to the existence of side seams in the pipe making.

3.Plastic coextrusion hose

　　

　　Plastic co-extrusion hoses use co-extrusion technology to co-extrude materials of different properties and types together to form a one-time molding. Plastic co-extrusion hoses are divided into single-layer extrusion hoses and multi-layer co-extrusion hoses. The former is mainly used for fast-consuming beauty salon cosmetics (such as hand creams) that require high appearance and low actual performance requirements. ), the latter is mainly used for the packaging of cosmetics in high-end beauty salons.

　　

　　There are many advantages of plastic co-extrusion hoses. If there is no side seal, the appearance effect is better than that of composite hoses. This is a must-have for cosmetic hose packaging in high-end beauty salons. Multi-layer co-extrusion is added with barrier properties such as EVOH, etc., which has excellent gas barrier properties, which can effectively prevent the infiltration of oxygen and peculiar gases, and prevent the leakage of the content fragrance and effective ingredients. According to the different extrusion dies, various shapes of extruded hoses can be produced, such as round, oval, square, etc., to meet the needs of different consumers.

　　

　　At present, the decoration of the hose is mainly realized through direct printing and self-adhesive labels. The process of making tubes and then printing for traditional extruded hoses usually uses offset printing and screen printing, while non-drying printing can use diversified combination printing processes such as letterpress, flexo, offset printing, silk screen, hot stamping, etc., with difficult colors. The performance is more stable and excellent. Appearance decoration is carried out through direct printing or self-adhesive labels to carry text or pattern information and enhance the value of product packaging.

　　

　　Filling process of plastic hose

　　

　　General working principle: The neatly placed hoses to be filled from the large-capacity hose silo through the automatic pipe feeding device are automatically inserted into the positioning mold after being aligned in sequence. The positioning molds rotate with the turntable and stay in different positions. At the workstation. Put the paste that needs to be filled into the closable cone-shaped barrel, through the plunger type quantitative filling valve directly connected to the barrel, accurately and automatically inject it, and intermittently stay in the hose at the filling station, and the large pan Continue to rotate, and quickly bring the hose filled with material to different tail sealing stations, and the manipulators of each station will immediately seal the tube tail. Different filling capacities can be obtained by adjusting the capacity adjustment table. By changing different manipulators, two folding, three folding, saddle folding and other different folding forms of metal pipes such as aluminum tubes can be completed. All plastic pipes, composites The heat sealing of the tube works. After the end sealing is completed, the typing manipulator will automatically print the production date, production batch number and other codes on the end of the tube.

　　

　　Matters needing attention: In the entire filling and sealing process, the two stations of filling and sealing are very worthy of attention, because if they operate unreasonably, they will directly cause product leakage. When filling, the material body must not contaminate the hose wall; the pressure and temperature parameters on the equipment when sealing the tail should be selected appropriately, and the processing window of the hose material needs to be explored and set to the best state in advance. Otherwise, the surface of the hose will be white, wrinkled, and leaking due to false seals.

　　

　　If there is a replacement hose manufacturer, you need to pay attention to the diameter and tolerance of the hose produced, and adjust the size of the matching blanching head and cooling ring in time to achieve the best sealing effect.

　　

　　Filling innovation case: combined with all-plastic composite soft

　　

　　Tubes and plastic co-extruded hoses can be made into transparent hoses. The filling and sealing equipment manufacturer Norden uses positioning molds to perform autobiography at different angles while rotating with the turntable to present the material spirally in front of consumers. , Greatly enhance the value of brand competition. As we all know, the poor quality of the hose seal will directly cause the product to leak, which will cause a great negative impact on the brand in the market. Norden company installed a nitrogen filling device on the original filling station at the same time, and added a nitrogen detection device after the sealing station to ensure the quality of the sealing.

　　

　　Prospects for future development trends

　　

　　As mentioned at the beginning of the article, tube packaging is not only used in daily necessities and beauty salon cosmetics; it is also used in packaging such as various medical supplies and food. Its inherent advantages will continue to maintain a certain market share in future packaging categories. In recent years, more and more beauty salon cosmetics manufacturers have begun to pay attention to environmental protection issues, and green packaging will become a trend. Materials with good biodegradability have become the new favorites.

　　

　　Protective, functional and decorative

　　

　　Multi-layer composite hoses will seize more markets in the future, and multi-layer co-extrusion hoses will gradually replace single-layer co-extrusion hoses, further enhancing the protection of cosmetics in beauty salons. In addition, the use of advanced technology minimizes the visibility of the joints of the plastic hose, making the plastic hose look more beautiful. At the same time, how to improve the hose consumption experience of consumers is also what we need to think about in the hose industry, which will also be one of the development trends in the future.
