Edit date:2022-09-27With the improvement of living economic standards, customers are more aware of environmental protection, and more and more businesses choose aluminum tubes as their packaging containers. Many countries have aluminum tube factories, especially India, China has a number of professional aluminum tube manufacturers.
As a manufacturing country of China, flexible aluminum tube manufacturers provide trillions of aluminum tubes each year to domestic and foreign customers, which is bound to produce a very large number of defective empty metal tubes, then these defectived soft metal tubes and how will be handled? Where did they go? In this way, we need to speak about the properties and advantages of aluminum.
What are the properties and advantages of aluminum?
As a metal material, the advantages of aluminum are obvious.
1. Corrosion resistance: aluminum rapid oxidation, the resulting aluminum oxide surface coating can resist further corrosion of air, water and chemicals. The protective coating is transparent, colorless and non-polluting
2. Colorable: Aluminum can be easily colored by anodizing and can hold the coating well. Aluminum can be finished with coloring in various ways, like we can do 4c, 6c offset printing on empty aluminum squeeze tubes. It is a very very important character for metal packaging containers.
3. Lightweight: Aluminum is about one-third the weight of steel. This makes it cheaper to transport and can also help make lighter machines when needed.
4. Economical: Although aluminum is not the cheapest price material, it is still more economical than brass or stainless steel, so it is usually the best choice for non-corrosive applications.
5. Hardness: Aluminum has the highest strength-to-weight ratio of any metal.
6. Electrical conductivity: Aluminum has even better electrical conductivity than copper.
7. Non-magnetic: Aluminum is a good choice for applications where magnetism needs to be avoided. It does not generate additional magnetic fields and does not play a disturbing role in precision instruments. This advantage is very suitable for use in cell phone cases, power supply metal cases, both to increase the metal touch and not much weight, but also does not interfere with the reception of cell phone signals.
8. Recyclable: Aluminum is 100% recyclable and will not lose any natural properties. Recycled aluminum can save lots of energy and money, bring huge profit to the market.
The aluminium material also have what are not well-known characteristics that what impact and benefits will have on our lives.
1. It has good ductility.
Its ductility is second only to gold and silver, and can be made thinner than 0.006 mm aluminum foil. These aluminum foils are widely used for packaging cigarettes, candy, etc. They can also be made into aluminum wire, aluminium strips, extruded into a variety of shaped materials, and can be rolled into a variety of aluminum products. Aluminum can be cut, drilled, and welded by general methods.
2、Good reflection performance of light and heat.
Reflecting ultraviolet light is stronger than silver, the purer the aluminum, the better its reflective ability, so it is often used to manufacture high-quality reflective mirrors, such as solar stove reflectors, and can be used as a thermal insulation material.
3、With sound-absorbing properties
The acoustic effect is also better. So the broadcasting room, modern large building indoor ceiling, etc. also use aluminum.
4、Low temperature resistance
Aluminum in low temperature, its strength instead of increasing without brittleness, so it is ideal for low-temperature device materials, such as refrigerators, freezers, Antarctic snow vehicles, and hydrogen oxide production equipment. At the same time, the low-temperature resistance of aluminum is small, the resistance of aluminum is lower than that of high purity copper and silver when it is below 50K, and aluminum becomes a superconductor when it is below 1.2K.
The above is part of the summary of the advantages of aluminum and aluminum alloy, these advantages are often closely related in our life, but we are difficult to find out, so it is very reasonable that aluminum and aluminum alloy can flourish in human life.
The advantages of collapsible aluminium tubes
And the flexible empty aluminum tube is one kind of metal tube made from Aluminum, must have some natural advantages of aluminum, so these decades gradually occupy an important position in the packaging industry, and is widely used in pharmaceutical ointment packaging, cosmetics packaging, such as hair dye, hand cream, facial cream and so on, daily chemical products, such as toothpaste, shaving cream, shoe polish, etc., and food, pet nutrition cream, etc., and glue, caulk, etc., and children’s oil paint, watercolor, etc many usage.
1. Aluminum material does not rust, its oxidation is non-toxic, has good shading has excellent moisture and gas barrier
2. Good processing performance, no rebound, thermal conductivity, good ductility, sealing, and full protection of the contents.
How do deal with the defective aluminum squeeze tubes in production?
So how to deal with the waste metal tube produced in the production process?
Can you guess what this picture below is? Yes, this is the flexible aluminum tube compressed and re-melted into a scrap aluminum block. Somebody will buy these aluminum blocks for reuse for other aluminum products
Remelting recycled aluminum to produce recycled aluminum ingots requires only 5% of the energy required to convert unaluminized aluminum into virgin aluminum ingots, making it very easy to recycle. This is a unique advantage over plastic tubes, aluminum composite tubes, laminated tubes （ABL tubes), and other packaging containers produced by plastic.
In the past, the direct remelting process has been used manually. This process not only has a low metal recovery rate (25%) but also has serious fume pollution and poor labor conditions. And now from the material to pressed into the block of six operations are all mechanical operations, the aluminum recovery rate is almost two times the old method, and the pollution problem has also been basically solved.
In summary, we know why aluminum is 100% recyclable now. Aluminum is a 100% recyclable material and aluminum squeeze tube is 100% recyclable green packaging container.
Aluminum not only ticks all these characteristics but they are also eco-friendly which makes them acceptable in society. Sourcing for aluminum tube packaging is to be used as cosmetic tubes, pharmaceutical ointment tubes, food packaging tubes, artistic oil paint packaging tubes, and others. It is in fact not stressful as so many companies worldwide are beginning to embrace this idea.
There are so many companies that specialize in the production of these collapsible tubes. Beauty Sky Packaging is the most reliable supplier of empty aluminum tubes.
