Product Description:
The aluminum collapsible tube for cosmetics cream refers to the soft metal collapsible tube, which is made of pure aluminum slug or flakes.
The quality of aluminum collapsible tube is determined by various factors. The purity of aluminum, the performance of the production process, skillful workers, and the quality control ability of the manufacturers play significant roles. Junsam Packaging has been supplying aluminum tubes at a purity of 99.7% aluminum. Our machines excel in extrusion, application of inner lacquer, bottom latex, and printing of aluminum collapsible tubes, demonstrating exceptional efficiency and precision in their manufacturing process.

How to make an aluminum flake or slug into a functional aluminum collapsible tube for cosmetics?
Step 1: Lubricant coating
To make the next step of extrusion practical, Zinc stearate powder must be applied evenly on the surface of the aluminum flake/slug.
Step 2: Slug extrusion, tube trimming & annealing
All aluminum collapsible tubes take forms and shapes once the slugs are extruded into the tube, and get through with trimming and annealing. Let’s elaborate on this: every single piece of aluminum slug will be extruded into a tube shape. After that, the tube goes through the trimming process from which the nozzle is threaded, shaved, and trimmed. As the newly extruded tubes are too stiff to be collapsible, so they have to go through the oven equipment for annealing.
Step 3: Inner lacquer
The lacquer is not necessary for the tubes of glue, adhesive, or grease. But it plays a critical role, especially for the tube of hair color. Because it protects the dyeing cream from the reaction with the aluminum.
Step 4: Exterior coating
Polyester resin in white color is usually coated on the exterior base of the tube. The base coating makes a glossy background for the direct printing of custom designs on it.
Step 5: Capping
Generally, all tubes must be delivered with caps. Most of the caps can be screwed by the automatic capping machines in our factory. But some caps must be screwed manually. Such as the octagonal caps.
Step 6: Latex lining
Latex lining is not mandatory. However, it is recommended for those products sensitive to air and moisture.
There it is time to fill and seal the tubes.
