Plastic tube is an international advanced packaging container, non-toxic and tasteless products, easy to use health, bright and beautiful surface, low price. Widely used in cosmetics, medicine, food, detergent and other daily necessities packaging, can highlight the value of products. tubes are economical to pack, easy to carry and suitable for holding emulsions and colloid. In recent years, with the rapid development of modern packaging industry and the continuous optimization of plastic tube packaging, tube packaging has a strong momentum of development.
Main applications of tube packaging
Plastic composite tube because of its convenient use, economy, good health, has become one of the main packaging varieties of cosmetics, medicine and food. Since the 1990s, China has introduced a large number of advanced composite tube production equipment from Europe, America, Japan and Taiwan Province, with a strong development momentum. Strong growth in skin care products and bath products will drive an above-average increase in tube packaging, especially upright tubes, according to the report.
tube has other material incomparable advantage, therefore, since comes into the world, on cosmetic and medicine packaging cut a figure. At present, it has become an indispensable form of packaging for cosmetics and pharmaceuticals. The plastic composite tube is mainly used in the packaging of cleaning cream, facial cleanser (milk), body wash, shampoo, hair conditioner, hair colorant, depilating cream, toothpaste and other products in the cosmetic industry. At present, cosmetics are the largest customer group of tube, accounting for about 60% ~ 70% of all tube business. tube in the pharmaceutical industry is mainly used for the cream, paste type of external medicine packaging. The proportion of medicine in tube package is 15% ~ 20%.
Classification of plastic composite tube
Plastic tube can be divided into single-layer tube and multi-layer tube according to material classification.
Single layer tube includes metal tube and plastic extrusion tube; Multilayer tube includes aluminum-plastic composite tube, plastic composite tube and plastic co-extrusion tube. According to the processing technology classification, the tube can be divided into seamless pipe and slit pipe. Seamless tube includes cold stamping forming, rolling forming and extrusion forming; Welded pipes include high frequency welding, ultrasonic welding, hot welding and other forming methods. One of the extrusion molding can be processed multiple or single plastic tube.
Development trend of composite tube sheet
Aluminum foil is thinner

The sheet of composite tube is usually composed of white polyethylene, acid copolymer, aluminum foil, transparent polyethylene, etc. Conventional sheets are very thick, with aluminum foil typically 40 or 30. With the continuous improvement of technology, aluminum foil is getting thinner and thinner, and its proportion in the sheet material is also getting smaller and smaller, from 29.44% in 1980 to 12.21% at present. Now the thinnest foil is only 12, which brings the barrier closer to the content.
The sheet is transparent
More and more color creams and gels are becoming popular among consumers. When these products are installed in transparent composite tube, its attractive color and good texture let a person fondle admiringly, transparent tube packaging has undoubtedly played the role of icing on the cake. However, when using transparent tube, the contents of the tube are easy to be degraded by ultraviolet radiation. At present, the company has developed a 'UV barrier' product formula, which can effectively protect the filled product from uv damage.
Environmental protection is taken seriously
The most practical and rational way to produce environmentally friendly tubes is to maximize the use of economical, recyclable sheets and reduce raw materials. When the thickness of the aluminum foil barrier layer in the tube is reduced from the traditional 40 to 12, it can save a lot of resources; When the aluminum foil barrier layer is completely eliminated and replaced by EVOH (ethylene vinyl alcohol copolymer), the composite pipe can be completely recycled and reused.
Whether it is cosmetics, medicine or food, the first consideration of packaging is hygiene performance, followed by barrier performance, printing adaptability and chemical resistance. Of course, economy and ease of use must also be considered.
Basic, streamlined, simple -- the words used to describe cosmetic packaging, and tubes in particular, were only a few years ago. The trend has shifted in a different direction in the blink of an eye.
'You're seeing a big shift away from basic packaging,' says the industry's tube packaging experts. The shift is certainly from simple white packaging to more colorful tubes. Some malls and stores, such as Wal-Mart, have had a big influence on this trend because their shelves also feature lots of colorful tubes; Experts emphasize that this is the need for shelf effect.
Nowadays, consumers care a lot about the packaging of products, and many people prefer to buy things with unique packaging. Indeed, if you want to jump through the hundreds of items in a supermarket and grab customers' attention all at once, you won't have to put a lot of effort into packaging. Packaging that is novel, easy to use, safe and looks high-tech is bound to be more eye-catching. Stores and stores are taking the trend seriously, and shelves feature colorful tubes for the following reasons:
Strong product decorative effect
Many large cosmetic companies are known to have used tubes with elaborate design. But the market is increasingly demanding tube packaging, with more elaborate designs, softer touches and the ability to place pictures on composite tubes. Recently, the trend of metal appearance is still very hot for tube packaging. Interest in pearls and rainbow-colored effects continues, all achieved by adding pigment to the tube material.
As for the decoration technology of the tube packaging, the users also put forward their views. The application of screen printing from four and six colors to eight or ten colors can better strengthen the decoration effect of the tube packaging. In interviews, cosmetics companies agree with the trend, 'Consumers are pushing tube packaging to a higher level of graphic clarity. Therefore, we need to complete the graphic design they need.' Avon's latest innovation is embossed composite width-width labels that create a touchable pattern on the tube's surface. In effect, it is embossed on the wide label itself. These give the traditional composite tube a more upscale appearance.
Excellent anti-extrusion effect
With the increasing use of fully extruded plastic tubes in personal care products, many packaging users believe that tube packaging helps to solidify the brand identity. Because tubes are often an extension of a particular brand of product, the product manufacturer may be prepared to seek different types of packaging from different suppliers. One way to ensure that a line of products looks the same is to use the same pressure-sensitive label on all packages.
Shape and function advantages
It is known that one of the most popular styles or shapes in the tube is the oval shape. Until recently, the only shape available in tubes was a circle, but with the advent of oval shapes, tube-makers have created a new dynamic point in the market.
In order to provide a better product in tube form packaging, the packaging users interviewed suggested that tube manufacturers should switch to multilayer co-extrusion tubes instead of direct single-layer tubes that can be used to package items that would normally not fit, are difficult to fit, or would affect shelf life. Multi-layer composite tubes have grabbed more market share due to better decorative capability and capacity.
In general, plastic composite tube has other materials incomparable advantages, therefore, since the advent of cosmetics and pharmaceutical packaging on the cutting edge. At present, it has become an indispensable form of packaging for cosmetics and pharmaceuticals.

At present, with the adoption of some new materials and new processes, the composite tube presents the following trends.
Environmental protection
Environmental protection is not only about the disposal of packaging waste, but also about the pollution to the environment and the resources consumed in the production process. The introduction of the aluminum-plastic composite tube and the full-plastic composite tube adopts the economical and easily recycled sheet material to the greatest extent, especially the full-plastic composite tube. When EVOH (ethylene vinyl alcohol copolymer) and other high barrier materials are used, it completely replaces the aluminum foil. The composite pipe can be fully recycled and conducive to biodegradation. Sanying has successfully developed all-plastic composite tube on the basis of aluminum-plastic composite tube, which is widely used in toothpaste packaging. However, compared with aluminum-plastic composite pipe, there is a certain gap in extrusion resilience and barrier property, which will still limit the process of replacing aluminum-plastic composite pipe in a quite long period of time.
Health performance
The compound tube is mainly applicable to the packaging of oral care products and cosmetics, etc. Therefore, from the consideration of ensuring the safety performance of its products, hygiene performance is always the first consideration, and there is a growing phenomenon. Reflected in the raw materials, the first film, particles, adhesives, ink, and other physical and chemical indicators and abnormal toxicity is limited; In the choice of technology, different compound technology will have different influence on the residual solvent of sheet and tube. In addition, the environment of the production workshop, the cleanliness of the air, such as the number of microorganisms, suspended matter, dust, and the hygiene of the production workers, all have an impact on the sanitary performance of the final product. In addition, for different target markets, its requirements for the sanitary performance of the composite pipe are not the same, such as exported to Japan, the United States and other countries, it has a high requirement for the residual solvent in the ink, heavy metal content.
Low cost,
Due to the pressure of the composite tube manufacturers on the cost of raw materials, it objectively leads to the continuous lowering of the composite tube production cost by the composite tube manufacturers, which is specifically reflected in:
1. Thinner aluminum foil and tighter interlaminar structure. The use of aluminum foil in the aluminum plastic composite tube sheet, from the original 40 to now prevailing 20 to 30, the thinnest has been done to 12. At present, Sansakura has been used in many aluminum-plastic composite tubes with a thickness of 12 aluminum foil sheet, 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 aluminum foil and ensure its good product performance at the same time, virtually every reduction is due to technological innovation and equipment improvement or even the improvement of other materials.
2. Reduce the loss in the production process. For the production of aluminum-plastic composite tube, the gravure printing process with large width and double-head or multi-head co-extrusion technology are adopted as far as possible, and the working procedure is improved and the production speed is increased to maximize the production efficiency and reduce the loss.
personalized
At present, more and more emphasis will be placed on individuation in the material use and appearance design of composite tube. For example, non-standard pipe diameter and personalized length-diameter ratio, characteristic pipe shoulder and cap, ellipse and other pipe body selection, unique cut shape of sealing tail, wide application of sealing film, bronzing, screen printing, marking and other modification processes, as well as the use of photo-changing ink, laser cursor and other anti-counterfeiting technologies.
In a word, with the further development of composite tube, it will be more and more widely used in the field of daily chemical products.
