As a metal packaging container, aluminum collapsible tubes are 100 recyclable and good looking with 1 color–6 color printing, to be a common packaging material in daily life, so they are often used for hand creams, hair dyes, glues, ointments, paints, toothpaste, food and other creams/pastes which are good sales. Squeeze aluminum tubes like paint tubes, hand cream tubes are lightweight and easy to carry and shipping, but how to protect the cream won’t leaking? The soft aluminum tubes are made of pure aluminum and they have a good seal character. After squeezing out the cream from the flexible aluminum tube, the tube body will collapse (not rebound), which means that air and moisture will not flow back into the tube, reducing the chance of contamination of the contents. It protects the creams well.
How do squeeze the cream from the aluminum tube? It is from the unsealed mouth of the aluminum tubes, the end of the tubes are sealed after filling creams. There are 2 types of mouth: Open-end (open tip) & closed-end ( sealed tip), called open-mouth aluminum tubes and sealed tip aluminum tubes.

How to distinguish the aluminum open-end tube from the aluminum closed-end tube?
In addition to the pointed nozzle we described earlier, (see article ). Empty aluminum tubes have an open and closed mouth of two kinds, the tubes’ types are flat nozzle cylindrical tubes, but the nozzles are for different needs and different designs. In addition to the difference in appearance, these two hoses also have different roles!
The distinction between aluminum open-end and aluminum closed-end tubes
1, With a different shape of the cover
The aluminum open-end tube nozzle for the opening, need to match the special sealant cap to achieve the best sealing effect, the top of the cap is usually flat, such as a round cap, or octagonal cap; the aluminum closed-end tube nozzle for the closed mouth, just match the ordinary plastic cap can be, but the cap must have a spike to pierce the layer of aluminum foil and can squeeze out the cream inside.
2、The capacity of conventional filling is different
All volumes and dimensions (Dia. 11mm, 13.5mm, 16mm, 19mm, 22mm, 25mm, 28mm, 30mm, 32mm, 35mm, 38mm, 40mm) can be produced to open nozzle or sealed nozzle, but the capacity of aluminum open mouth tube is generally larger, usually, 30-200ml which is good for cosmetics, like hand cream, facial cream, mask….etc.; While the capacity range of aluminum sealed-tip tube is larger, 3-200ml are available.
3、Difference in filling contents
The open-tip aluminum tube is not completely sealed, so it is mostly used for filling viscous sticky cream products, such as hand cream, grease, earth cream, facial cream, etc.; While sealed tip aluminum tube has a wider range of applications due to its sealed mouth, and can be used to fill little diluted creams, such as oil paint, glue, cosmetics, pigments, hair dyeing cream, etc.
4、Using instruction
Aluminum open mouth tube in use, only need to unscrew the cap, can be directly coated in the need to use, very convenient; and aluminum closed mouth tube sealing design, need to use the caps pierce the closed mouth of the aluminum foil to open. It can effectively isolate the air, moisture, water, bacteria, and other substances in the external environment, reducing the chance of the paste being contaminated and spoiled, and spoiled. The product can be stored for a longer period of time.
5、Price difference
Is there any difference between the open-mouth aluminum tube to the sealed-tip aluminum tube? Yes, the open-mouth tube is a little higher than the sealed tip tube.
- The material aluminum ingot cost is a little bit higher
- The production cost is higher, the unqualified goods are much more than sealed tip packaging tube, and the defectives rate is higher.
- The quantity demand is less so all the purchasing cost and production cost is higher. There are only 20%–30% empty aluminum tubes with open tips, including the long nozzle tube with smaller open mouths.
Which nozzle of the aluminum tube should be used as packaging materials? In addition to the aesthetic appearance, more consideration should be given to the nature of filling products.
Good products, need to have good packaging to effectively preserve quality. In addition to the product itself must be of high quality, the packaging must also be careful.
What are the differences of testing standards?
1, The closed nozzle of the aluminum empty tube according to the conventional test quality can be
2, The aluminum tube of the open nozzle than the closed nozzle requires an additional leakage detection
