Product description:

The aluminum tube for cosmeitc cream is refering to the aluminum 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, performance of production process, skillful workers and the quality control ability of the manufactures play significant roles. Junsam Packaging’s been supplying the aluminum tube at the purity of 99.7% aluminum.

How to make an aluminum flake or slug into a functional aluminum collapsible tube?

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 tube, and get through with trimming and annaealing. Let’s elaborate on this: every single piece of aluminum slug will be extruded into 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 direct printing of custom design on it.

Step 5: Capping

Generally all tubes must be delivered with caps. Most of 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 othose products sensitive to air and moisture.

There it is time to fill and seal the tubes.

Aluminum collapsible tube offers several advantages:

  1. Lightweight: Aluminum is a lightweight material, making the collapsible tubes easy to handle and transport.
  2. Durable: Aluminum is corrosion-resistant, providing durability and protection for the contents of the tube.
  3. Barrier Properties: Aluminum provides an effective barrier against light, moisture, and other external factors, preserving the quality of the contents.
  4. Recyclability: Aluminum is highly recyclable, making the tubes an environmentally friendly packaging option.
  5. Ease of Dispensing: The collapsible design allows for precise dispensing of the product with minimal waste.
  6. Aesthetic Appeal: Aluminum tubes can be easily customized with printing and labeling, enhancing product presentation and brand visibility.
  7. Long Shelf Life: The barrier properties of aluminum contribute to a longer shelf life for the products stored in the collapsible tubes.
  8. Hygienic: Aluminum is a hygienic material that ensures the purity and cleanliness of the contents, making it suitable for pharmaceutical and cosmetic applications.
  9. Convenience: The collapsible nature of the tubes allows for easy squeezing, ensuring convenient and controlled product dispensing.
