There are 2 types of nozzles of aluminum tubes: Long nozzle, and common flat nozzle.
Brief description: nozzle of aluminum tube
Aluminum packaging tube is a common packaging material in daily life, produced by 99.5% pure round aluminum ingot produced from square aluminum plates. The end user squeezes the cream from the nozzle of the packaging tube.
The filling method of flexible aluminum tubes is different from the plastic tube and aluminum laminated tube. Plastic tubes and aluminum laminated tubes have two kinds of shapes: one is the end of the tube is sealed, and the nozzle is open without a cap or with a cap, so the creams can be filled from their mouths. Another is the mouth is sealed with a cap, but the end of the tubes is open, creams can be filled from the tubes’ end and sealed. The empty aluminum tubes are all open at the end, the creams must be filled from the end of the aluminum tubes and then sealed, they can’t be filled from the mouth. The mouth is small like 1.0mm, 0.5mm, even 0.2mm or 0.1mm, and the nozzle is given with a cap all the time, the customer does not need to open the cap again, so the nozzle can be opened or closed.
Today we are going to talk about the aluminum tube’s nozzle. Empty aluminum tubes’ nozzles can be divided into the closed nozzle, open nozzle, and the open nozzles divided into ordinary open nozzle, and long nozzle. We can also divide the aluminum round tube into long nozzles and flat nozzles according to the shape of the thread. Two of the most common types of packaging tubes are long nozzle aluminum tubes and common thread aluminum tubes! They are named after the different designs of their nozzles.
Although both are the same aluminum tubing and have the same function, their production process, tube type, and filling content are different!
The comparison of long nozzle aluminum tube and common nozzle aluminum tube
1, The long nozzle aluminum tube is usually open, with a special plastic cap to achieve the optimal sealing effect.
The flat nozzle tube has two kinds of tips: open and closed ( sealed). The open mouth of tube needs to be paired with a special sealant cap to avoid spillage of the cream and reduce the chance of the cream being contaminated and spoiled. It is a very important quality indicator. For the open mouth, it is sealed by a thin aluminum film in production. The aluminum ingots are different for the different mouths of tubes.
2、The dimension of the tip of the tube
The opening of the long nozzle aluminum collapsible tube is usually very small, and it is mostly used for filling eye ointment, adhesive, RTV sealants, etc. with a small volume and precise gluing.
The opening of the common nozzle tube is generally larger and flatter, which is mostly used to fill general chemical paste products, such as cosmetics, toothpaste, ointment, anesthetics, nail paste, grease, oil painting, etc.
3、The difference of spreading the products
The pointed part of the long nozzle extends outward for a distance, which is convenient to squeeze out glue, and eye ointment and apply it directly to the place where it needs to be used, so as to apply for glue and medicine precisely.
The common flat nozzle tubes will need to be distinguished according to the product, such as cosmetics, hand cream, etc., directly squeezed out and can be spread by hand. Similar to glue or grease, oil coloring, etc., sometimes need to use cotton balls, and scrapers to assist in the application
4、Capacity
The capacity of the commonly used long nozzle tube is small, usually 3-15ml, and the general adhesive sealant, RTV sealant tube can reach 200ml.
The capacity range of the common flat nozzle tube is relatively large, with a conventional size of 3ml-200ml.
5、The sealant of the pointed nozzle tube is poor, often used to fill the adhesive or grease that is not easy to cure. Generally speaking, the application range is a little narrower, and the usual production is less, more often used in glue tubes, etc.
Flat mouth closed mouth tube has a better sealing effect and is often used to fill products that attach importance to sealing, such as pigments, hair coloring cream, hand cream, sunscreen, toothpaste, etc. Flat mouth tube is widely used, 80% of the products in the market with aluminum tubes are used flat mouth tube.
6、The materials of the matched cap for the empty aluminum tube
The lid of the spike tube is plastic, HDPE, or PE.
Flat nozzle tube matching cover materials are plastic, there are also metal, aluminum cover or zinc alloy covers, etc., a variety of shapes and styles, and more widely used.
7. Price comparison
The long nozzle of the tube requires more aluminum, and the raw materials is heavier, so the same size, same volume, and same thickness of tubes’ wall, and the same quality requirements of the product compared to the price of the common flat tube are slightly more expensive.
The use of long nozzle or flat nozzle tube depends mainly on the nature of the contents of the filling. Aluminum collapsible tube’s orifice design for the elonged or flat nozzle, mainly to meet the different needs of users. The point of consideration is that it can take into account the convenience of the user while maintaining good sealing performance.
So, somebody do not underestimate these packaging materials, its material selection, size, and shape design, for the use of products, transport, carry and preservation, play a key role! And it is especially important to choose a professional and reliable supplier with stable quality.
How do extrude the nozzle of the aluminum tube?
How does a soft aluminum tube make from? It is an interesting question. Aluminum tube is made from a piece of aluminum ingot.
In the first step in production, the aluminum ingot will be intruded into a hard aluminum tube the nozzle will be extruded at the same step. Then the nozzle will be trimmed in 2nd step together with tube’s length.
