What is the importance of applying end latex to aluminum tubes?
1, Enhance the sealing of the aluminum tube, to prevent the leakage of cream/paste/ointment objects.
As a kind of metal packaging material, although the aluminum tubing becomes soft and foldable after annealing, but it still has the properties of metals, if the folding tail is not careful and the force is not enough, it is likely that the product will leak from the tail. So the application of latex becomes very important for some items.
Molecularly fine cosmetics or adhesives filled in pure aluminum squeeze tubes, some will occur the phenomenon of cream leakage from the tail, which indicates the sealing of the seal is not enough.
In the production of aluminum flexible tubes, if you can spray a circle of latex on the inner wall of the tail inside of the aluminum tube, the end latex can fill the tiny gap when folding the tail seal to enhance the sealing and avoid embarrassing leakage. This is most important for some tubes are sealed by hand.
2, Effectively isolate moisture and air to avoid contamination of the contents.
If the content of the filling is easy to react with air or moisture, it is recommended to use the pure aluminum tube with the end latex to fill, after sealing, it can effectively isolate the outside oxygen, moisture, bacteria and other substances from invading, reducing the risk of deterioration of the content.
3, To ensure the shelf life of the contained cream/paste/ointment material.
For the paste material which is easy to oxidize and deteriorate by moisture, enhancing the sealing means that the shelf life of the product can be ensured so that the product can be sold on the shelf for a longer period of time, and the satisfaction of the end consumer can be ensured.
