The diversified development of plastic hose packaging

Plastic hose is an internationally advanced packaging container. The product is non-toxic and tasteless, and it is hygienic and convenient to use. The surface is bright and bright, beautiful, and low in price. Widely used in cosmetics, medicine, food, detergent and other daily necessities packaging, can highlight the value of the product. The tube packaging is economical and convenient, easy to carry, suitable for containing emulsion and glue. In recent years, with the rapid development of the modern packaging industry and the continuous optimization of plastic tube packaging, the development momentum of tube packaging has been strong. The main application areas of hose packaging Plastic composite hoses have become one of the main packaging varieties for cosmetics, medicine and food due to their convenience, economy and good hygiene. Since the 1990s, China has introduced a large number of advanced composite hose production equipment from Europe, America, Japan and Taiwan Province, and the development momentum is very strong. According to related reports, the strong growth of skin care products and bath products will promote the growth of hose packaging at a higher than average rate, especially for upright hoses. The hose has the advantages that other materials are incomparable. Therefore, since its inception, it has emerged in cosmetics and pharmaceutical packaging. Now it has become an indispensable form of packaging for cosmetics and medicines. Plastic composite hoses are mainly used in the cosmetics industry for packaging products such as cleansing cream, facial cleanser (milk), shower gel, shampoo, shampoo, conditioner, hair dye, depilatory cream, toothpaste and other products. At present, cosmetics is the largest customer group for hoses, accounting for approximately 60% to 70% of all hose businesses. In the pharmaceutical industry, hoses are mainly used for packaging creams and ointments for external use. Medicines account for 15% to 20% of the tube packaging. Classification of plastic composite hoses Plastic hoses can be divided into single-layer hoses and multilayer hoses according to their material classification. Single-layer hoses include metal hoses and plastic extruded hoses; multilayer hoses include aluminum-plastic composite hoses, plastic composite hoses and plastic co-extruded hoses. According to the classification of processing technology, hoses can be divided into seamless pipes and seamed pipes. Seamless pipes include cold stamping forming, roll forming and extrusion forming; seamed pipes include high-frequency welding, ultrasonic welding, thermal welding and other forming methods. Among them, extrusion molding can process multilayer or single-layer plastic hoses. The development trend of composite hose sheets The aluminum foil is thinner The composite hose sheets are usually composed of white polyethylene, acid copolymer, aluminum foil, transparent polyethylene and so on. The traditional sheet is very thick, and the aluminum foil is generally 40μ or 30μ. With the continuous improvement of technology, aluminum foil is getting thinner and thinner, and its proportion in the sheet is also getting smaller and smaller, from 29.44% in 1980 to 12.21% at present. Now the thinnest aluminum foil is only 12μ, which makes the barrier layer closer to the content. Sheet transparency More and more colored pastes and gel-type ointments are being loved by consumers. When these products are packed in transparent composite hoses, their attractive colors and good texture make people love them. The transparent hose packaging undoubtedly plays a role in icing on the cake. However, when using a transparent hose, the contents of the tube are susceptible to degradation by ultraviolet radiation. At present, companies have developed 'ultraviolet blocking' product formulas, which can effectively protect filled products from UV damage. Environmental protection is valued The most practical and reasonable way to produce environmentally friendly hoses is to use economical and easy-to-recycle sheets to the greatest extent and reduce raw materials. When the thickness of the aluminum foil barrier layer in the hose is reduced from the traditional 40μ to 12μ, a lot of resources can be saved; when the aluminum foil barrier layer is completely eliminated and replaced with EVOH (ethylene vinyl alcohol copolymer), the composite tube can be completely recycled. use. Whether it is cosmetics, medicine or food, packaging must first consider hygiene performance, followed by barrier performance, printing adaptability and chemical resistance. Of course, economy and convenience must also be considered. Basic, streamlined, simple-these words used to describe cosmetic packaging, especially hoses, were only a few years ago. In the rapid changes, the trend has turned in another direction. 'You are seeing the industry itself move away from the basic style of packaging', the industry's hose packaging experts commented. This change must be a shift from simple white packaging to more colorful hoses. And some stores and stores, such as Wal-Mart, have a great influence on this trend, because their shelves also feature numerous colored hoses; experts emphasized that this is the need for shelf effects. Today's consumers are very concerned about the packaging of products, and many people prefer to buy things with unique packaging. Indeed, if you want to jump out of the hundreds of products in the supermarket and attract the attention of customers at once, it is impossible not to spend some time on packaging. Those packaging that are novel in appearance, easy to use, safe and seem to have a higher technological content are bound to be more eye-catching. Stores and stores are very comfortable with this trend, and the shelves are also featured with many colored hoses, which can be attributed to the following reasons: Strong product decoration effect It is understood that many large cosmetic companies have already used it. It has a delicately designed hose. However, the market has higher and higher requirements for tube packaging. They require the tube packaging to have a more exquisite pattern, a softer touch, and the ability to place pictures on the composite tube. Recently, the trend of metal appearance is still very popular for hose packaging. The interest in pearl and iridescent effects continues. These effects are achieved by adding pigments to the hose material. Regarding the decoration technology of tube packaging, users also put forward their opinions. From the application of four-color and six-color screen printing to eight-color or ten-color printing, the decorative effect of tube packaging can be better enhanced. In the interview, related cosmetics companies also agreed with this trend, “Consumers are pushing the hose packaging to a higher level of distinctive patterns. Therefore, we need to complete the pattern designs they need.” Avon’s latest innovation is embossed composites. Wide label, which makes a touchable pattern formed on the surface of the hose; it is actually embossed on the wide label itself. These give the traditional composite hose a more high-end appearance. Excellent anti-extrusion effect With the continuous application of fully squeezed plastic hoses in personal care products, many packaging users believe that hose packaging helps to consolidate brand characteristics. Because hoses are often a series expansion of a certain brand of products, product manufacturers may be prepared to seek different types of packaging from different suppliers. The way to ensure that the appearance of a series of products looks consistent is to use the same pressure-sensitive label on all packages. Advantages in shape and function It is understood that one of the most popular styles or shapes in the hose is the oval shape. Until recently, the only shape available in the hose was the circle, but with the emergence of the oval shape, hose manufacturers have created new vitality in the market. In order to provide better products in packaging in the form of hoses, the packaging users interviewed suggested that hose manufacturers should switch to multi-layer co-extruded hoses instead of direct single-layer hoses, as the packaging that can be used usually cannot be used. Contents that are imported, difficult to put in, or that will affect shelf life. Due to better decoration capacity and capacity, multilayer composite hoses have seized more market share. On the whole, plastic composite hose has the advantages that other materials are incomparable. Therefore, since its inception, it has emerged in cosmetics and pharmaceutical packaging. Now it has become an indispensable form of packaging for cosmetics and medicines. At present, with the adoption of some new materials and new processes, composite hoses show the following trends. Environmental protection Environmental protection is not only the treatment of packaging waste, but also includes the pollution of the environment and the resources consumed during the production process. The introduction of aluminum-plastic composite hoses and all-plastic composite hoses use economical and easy-to-recycle sheets to the greatest extent, especially all-plastic composite hoses. When using EVOH (ethylene vinyl alcohol copolymer) and other high barriers After the new material, the aluminum foil is completely replaced, and the composite pipe can be completely recycled and is beneficial to biodegradation. Sanying has successfully developed an all-plastic composite hose based on the aluminum-plastic composite hose, which is mainly widely used in toothpaste packaging. However, compared with aluminum-plastic composite pipes, all-plastic composite pipes have a certain gap in extrusion resilience and barrier properties. This will still limit the process of all-plastic composite hoses completely replacing aluminum-plastic composite pipes for a long time. . Hygiene performance The composite hose is mainly suitable for the packaging of oral care products and cosmetics. Therefore, from the perspective of ensuring the safety performance of its products, the hygiene performance is always the first factor to be considered, and it is increasing. Reflected in the raw materials, first of all, there are certain restrictions on the physical and chemical indicators and abnormal toxicity of films, particles, adhesives, inks, etc.; in the selection of processes, different composite processes also affect the residual amount of solvents in sheets and hoses. There will be different effects; in addition, the environment of the production workshop, the cleanliness of the air, such as the number of microorganisms, suspended solids, dust, etc., and the hygiene of the production workers, all have an impact on the sanitary performance of the final product. In addition, different target markets have different requirements for the hygienic performance of composite pipes. For example, when exported to Japan, the United States and other countries, it has high requirements for residual solvents and heavy metal content in inks. Low cost due to the lower pressure of the raw material cost by the manufacturers of composite hoses, objectively led to the continuous reduction of the production cost of composite hoses by the composite hose manufacturers. The specific manifestations are as follows: 1. The use of thinner aluminum foil and tighter Interlayer structure. The use of aluminum foil in aluminum-plastic composite hose sheets has dropped from the initial 40μ to the current 20μ to 30μ, and the thinnest has reached 12μ. At present, Sanying has used 12μ aluminum foil thickness sheets on many aluminum-plastic composite hoses, and has received good results. Of course, the reduction of the thickness of aluminum foil is by no means a simple subtraction. To reduce the thickness of the aluminum foil while ensuring its good product performance, in fact, every thinning of the aluminum foil benefits from technological innovation, equipment improvements and even other materials. Improved. 2. Reduce the loss in the production process. For the production of aluminum-plastic composite hoses, try to use larger width gravure printing process and double-head or multi-head co-extrusion technology, and improve the process and increase the production speed to maximize production efficiency and reduce losses. Individualization At present, there will be more and more emphasis on individualization in the material use and appearance design of composite hoses. For example, non-standard tube diameters and personalized length-to-diameter ratios, distinctive tube shoulders and tube caps, elliptical tube body options, unique tail-sealing incision shapes, wide application of sealing film, bronzing, silk screen printing Modification techniques such as, sleeve label, and the use of anti-counterfeiting techniques such as optical variable ink and laser cursor. In short, with the further development of composite hose, its application in the field of daily chemicals will become more and more extensive. Although new hose products are rich in variety and endless, keeping a balance with demand is still a challenge for hose packaging. Because for hoses, basically every order is customized, including size, degree, and pattern; therefore, the lead time for hoses is quite long. The increasing demand for hoses has led to a longer lead time for hoses, which is unwilling to see both manufacturers and customers, especially the timing of new product launches for packaging users. More compact. Therefore, many care product companies are seeking suppliers with shorter lead times. In addition, the application field of the form of tube packaging is not broad enough. The daily chemical and pharmaceutical industries are still the largest users of composite hoses. Currently, they are mainly used for packaging of some condiments in food. Applications in other fields need to be expanded. . Plastic hose is an internationally advanced packaging container. The product is non-toxic and tasteless, and it is hygienic and convenient to use.
